    The failure mechanism of the jaw plate mill<p></p>

    It is visible through the jaw plate mill, jaw crusher teeth plate wear belongs to a chisel wear. The jaw plate material is commonly used in water toughening treatment ZCMn13 high manganese steel. The scanning electron microscope to observe the grinding of the jaw plate can be seen that the surface of the jaw plate is squeezed into the concave and convex portions of the material, then be abrasive pushed to the formation of the pressure of the tongue grinding surface grinding surface can be seen a lot of grinding sharp corners caused by short-range sliding wear scar, and can see the surface of the jaw plate micro-cracks. Jaw plate wear, mainly due to the abrasive relative jaw plate of short-range sliding the chisel to cut the metal caused by debris and abrasive repeated extrusion deformation caused by the jaw plate material repeatedly, leading to metal materials fatigue off. Wear failure process is: ? material is repeatedly squeezed the chisel tooth plate, the formation of micro cracks in the surface of the jaw plate area, or in a prominent part of the roots of the extruding metal, this micro crack continues to expand to a connected, resulting in the shedding of the surface of metallic materials, formation of wear debris; ? material repeatedly squeeze the jaw plate metal materials by local fracturing or reveal, rupture or reveal part of the formation of wear debris off with the extrusion of impact materials. The ? materials relative jaw plate of short-range sliding the chisel to cut the tooth plate formation of wear debris. <p></p>

    Material selection of the jaw plate <p></p>

    Affect the jaw plate wear, hardness, toughness and wear-resistant materials. ? materials, hard materials extrusion shallow depth, small deformation, the material is also a small chisel to cut the amount of short-range sliding of the material; good ? toughness, ability to resist fracture, and to eliminate the brittle fracture process of extrusion impact to improve the anti-fatigue deformation cracking. The two factors sometimes are contradictory, how to match is a very difficult subject. <p></p>

    Different size specifications of the jaw crusher, feed size, sharpness (shape), extrusion of the tooth plate, the force of impact. Large and medium-sized specifications jaw crusher squeeze pressure, should also be considered by the impact of the impact and bending stresses in addition to considering the resistance of the material extrusion pressure and anti-sliding cutting. Large jaw crusher teeth plate is usually to adopt ZCMn13Cr2 modified high manganese steel. The high hardness of the material to resist the squeeze jaw plate material should be selected, micro chisel failure, and also have sufficient toughness to resist chisel impact fatigue failure. Be improved from both the structure of the jaw plate, in order to reduce the relative sliding of the materials and jaw plate, which is not only beneficial to improve productivity, but also beneficial to improve the life of the material; for our country, small jaw crusher, jaw plate The material is mainly high-manganese steel, very few factories producing low-<a href="http://www.gongluen.com.tw/">alloy cast iron jaw pull. <a href="http://www.gongluen.com.tw/">Due to the low toughness of the low alloy cast iron, during the use it is prone to fracture. Use in the manufacture of high-manganese steel, small jaw plate, in the fork due to the impact force is too small, the hardening is not obvious, its excellent wear resistance can play, and the jaw plate life is very short, usually for 200-400 h. The annual consumption is of a large number. Therefore, looking for new materials to improve its service life and reduce material consumption has received special attention.<p></p>

    Description of austempering and its advantages<p></p>

    Description of austempering and its advantages<p></p>

    <p></p>

    ARTICLE Description of austempering and its advantages <p></p>

    Austempering is a process of applying heat treatment on ferrous metals, like steel and iron. This procedure is basically done for improving mechanical properties of metal. The procedure begins with heating the metal till its austenitic state and then rapidly cooling it; along with maintain a high temperature for prevention of formation of martensite for an enhanced duration. By the use of this process, metals become tougher, strong and resists to wear and tear. <p></p>

    <p></p>

    The main aim of austempering is to provide strength driven materials in various machine parts. The concept of austempering is different from traditional form of heat treating, in which there is quick quenching of austenite in oil or fluid at room temperature. It will form martensite, which is hard, but on the same time, it is highly brittle and needs tempering for becoming ductile. The outcome of austempering is dependent on the material used for the same. Bainite is the name given to austempered steel and it is relatively more ductile than martensite. The final product doesn t require any tempering and is tough, sturdy and adds wear resistance. On the other hand, <a href="http://www.gongluen.com.tw/">austempered ductile iron results in production of ausferrite, which has greater strength. <a href="http://www.gongluen.com.tw/">Austempered ductile iron (ADI) is also used in manufacturing of many machine parts. <p></p>

      Cast Iron--the Valve s Material<p></p>

      Cast Iron--the Valve s Material<p></p>

      <p></p>

      Even in the ceramic valve, there are other materials except the ceramic material. The cast iron is one of the common valve materials. The cast iron is the general term of alloying including iron, carbon and silicon. According to the editor s knowledge of DSMATERIAL, the cast iron contains several categories, such as <a href="http://www.gongluen.com.tw/">grey cast iron, white cast iron, malleable cast iron, nodular cast iron, wriggle ink cast iron, alloy cast iron. <a href="http://www.gongluen.com.tw/">The grey cast iron has high carbon content , and the carbon is mainly of graphite form, with grey fracture. It has low melting point, and the shrinkage is small in solidification. <p></p>

      <p></p>

      Its compression strength and hardness are close to carbon steel and the shock absorption is small. In the white cast iron, there are little carbon and silicon, and the carbon is cementite, with silver fracture. The shrinkage is big in solidification and it is easy to have shrinkage cavity and fissure. The white cast iron has high hardness, fragility, and cannot bear the heavy impact. These are the little introduce of the valve s materials. <p></p>

      <p></p>

      According to the different property of the different materials, they can be used in various working conditions. The customers should know the different function of the valve materials to choose the better proper valve. For more information.<p></p>

        How to Maintain Lithium Battery<p></p>

        How to Maintain Lithium Battery<p></p>

        <p></p>

        At present, lithium battery are commonly used on mobile phone, laptop, digital camera and other electric device. To learn how to maintain lithium battery can not only prolong battery lifetime but also protect your device from potential damages.<p></p>

        <p></p>

        Don’t charge over 12 hours for the first time. When we purchase electronic devices powered by battery, sellers will usually tell us lithium battery charge time must up to 12 hours in the first time. Actually, this idea is wrong. Unlike common Ni-CD or Ni-MH battery, lithium ion batteries have been activated before left factory, otherwise its low self-discharge, so it’s unnecessary to charge lithium ion battery for such a long time in the first time. Lithium ion battery is ready after recharged, it will reach to best status after 3 or 5 cycles.<p></p>

        <p></p>

        Don’t not use unqualified charger. Many friends care for their electronic gadgets very much, but often avoid the affect of lithium ion battery. When pick up charger, original charger is the fist choice, second one is some hi gh quality charger, that with over charge protection function or brand charger. Poor battery charger leads to shorter cycles, even causes explore or fire.<p></p>

        <p></p>

        Avoid over charge frequently. Long time over charge will let battery interior in a level of high temperature, is bad for lithium ion battery and charger. Thus, fully charged yet is good enough, or lithium battery will become a little bomb if without over charge protection function.<p></p>

        <p></p>

        Avoid contact metal. Lithium ion battery’s contact is needed to be clean, and note that do not let battery contact get close to metal when take care or carry, it carries out short circuit or cycles.<p></p>

        <p></p>

        Avoid often use in high or low temperature environment. Lithium ion battery has its own proper work and storage temperature, if it’s in over high or low temperature environment in a long tern, will affects lithium ion battery’s use time and cycles highly.<p></p>

        <p></p>

        Avoid long time without use or recharge. For some uncertain reasons, personal electronic gadgets or lithium ion battery might be to leave unused 3 months or more, so that we need to recharge lithium ion battery for some electricity volume regularly, then storage( recharge electricity volume is 30-70% of capacity, depends on storage time and battery capacity).<p></p>

        <p></p>

        Avoid use lithium ion battery which full charged yet. Temperature will be very high after batter recharged yet, if use at once, electronic gadget’s internal temperature will raise soon, it affects electronics component greatly. http://www.minamoto.com/en/?ztitle=p...attery&panel=1

          The Application of a Lithium Battery in Electric Automobiles<p></p>

          The Application of a Lithium Battery in Electric Automobiles<p></p>

          <p></p>

          Lithium battery holds the advantages of high working voltage, small size, light weight, no pollution, and long life span. Therefore, it has extensive applications in portable electronic products like phones, laptops, digital camera and so on.<p></p>

          <p></p>

          A lithium battery is predicted to have a booming development in the future, which is based on the pressing demand of easing off the serious environmental pollution problem around the world. Actually, a major pollution comes from the emission of carbon dioxide of cars. With the fast development of economy, more and more cars appear in our city, which both bring convenience and troubles to us. We pay the convenience for traffic jam and serious environmental pollution. People become aware of the problem and want to change the situation.<p></p>

          <p></p>

          To reduce the emission of carbon dioxide, electric automobile is on its way to come on the stage, which is expected to discard the common way of burning gasoline to provide drive. A lithium battery is believed to have great potentiality in this application. And there are many advantages to apply the lithium battery to an electric automobile. Considering the environmental protection, the usage of a lithium battery in car will lessen the burning of gasoline and lower the emission of carbon dioxide, which will help for slowing down the greenhouse effect. Another point, using a lithium battery will also help to cut the cost of using a car. Due to the sever energy problem, price of gasoline rise constantly and the expense of driving a car become higher and higher. Moreover, a lithium battery has high energy-density and can keep working for a long time, which means you will never be afraid of lacking of gasoline. However, now if traveling for a long distance, you will also even gasoline to work together to offer drive. Anyway, the battery will cut your cost and give you more convenience. Last, it also has a small size and light weight which are easy to be moved and gives fewer burdens to the car, for which the electric car in the future can be smaller and smarter than now.<p></p>

          <p></p>

          All in all, there are many problems in the reach of applying the battery to electric car, such as balance quality, safety, and economical efficiency. Nevertheless, many professionals are committing themselves to working out the most efficient way to solve the problem and green cars using Lithium battery will do lead the automobile market in the future. http://www.minamoto.com/polymer.html

            Why Lithium Polymer Batteries Are the Top Choice For Powering Your Electronic Devices<p></p>

            Why Lithium Polymer Batteries Are the Top Choice For Powering Your Electronic Devices<p></p>

            <p></p>

            There are so many things that need batteries today, especially with all the electronics that are being sold. Who knew batteries would come in so many different shapes, sizes and types. You would think that buying a battery would be easy but now you need to be knowledgeable and know something about batteries before you purchase them. One of the more popular batteries today is the lithium polymer batteries. These batteries are thin and lightweight making them perfect for many of the electronic devices.<p></p>

            <p></p>

            The lithium polymer battery was introduced in 1996. It quickly gained the approval of many due to its lightweight construction and the fact that it was rechargeable. These batteries are now being used in many electronic devices such as portable video players, portable computers and many rechargeable electronic devices.<p></p>

            <p></p>

            The energy density is one of the important components of a good battery and lithium has the highest energy density of any battery being sold. The life cycles are also longer and the degradation of the battery is much slower than many. These batteries do have some disadvantages such as exploding if they become overcharged, faster capacity loss and a longer recharge time.<p></p>

            <p></p>

            The two main lithium batteries available for purchase are the lithium ion and the lithium polymer. The polymer battery is much safer than the ion battery because of the way in which the lithium is suspended. The polymer battery suspends the lithium in a polymer gel and the ion battery suspends the lithium in an organic solvent. The organic solvent material is highly flammable unlike the polymer gel. The ion is also prone to burst into flames if there is a short or if the battery is crushed. The polymer is less likely to burst into flames in either case.<p></p>

            <p></p>

            An ion battery contains metal casing to house the suspended lithium whereas the polymer battery does not need them because the lithium is housed in the gel in which it is suspended. This in turn makes the polymer a more lightweight and flexible battery due to the elimination of the cylindrical metal casings. With the polymer being lightweight and flexible this appeals to the electronics developers and designers.<p></p>

            <p></p>

            The lithium polymer batteries are also referred to as LiPo or LiPoly batteries. Lithium batteries are quickly replacing the old NiCad (Nickel Cadmium) and NiMH (Nickel Metal, Hydride) batteries. Lithium is the lightest of all metals and has the highest energy per unit weight. It is no surprise then that lithium is quickly replacing nickel as the metal of choice for batteries.<p></p>

            <p></p>

            Prices can be good indications of product worth and since the LiPo batteries are much more expensive than the nickel batteries and lithium ion batteries, you automatically have an idea that it is going to be a good product. It is definitely one that falls under the old saying, "you get what you pay for".<p></p>

            <p></p>

            Based on the information and known facts, it is evident that a lithium polymer battery is currently a top of the line battery. These batteries are great for electronics because of their lightweight flexible design. They are more expensive but well worth the money you pay for them. Lithium polymer batteries are the way to go for a reliable high energy battery. http://www.minamoto.com/polymer.html

              The Li-Polymer battery: substance or hype?<p></p>

              The word ‘Lithium Polymer’ has become synonymous with advanced battery technology. But what is the relationship between ‘polymer’ and the classic Lithium Ion battery? In this article we examine the basic differences between the Li-ion and Li-ion polymer battery. We look at packaging techniques and evaluate the cost-to-energy ratio of these batteries. <p></p>

              <p></p>

              The Li-polymer differs from other battery systems in the type of electrolyte used. The original design, which dates back to the 1970s, uses a polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows the exchange of ions (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.<p></p>

              <p></p>

              The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile profile. There is no danger of flammability because no liquid or gelled electrolyte is used.<p></p>

              <p></p>

              With a cell thickness measuring as little as one millimeter (0.039 inches), design engineers are left to their own imagination in terms of form, shape and size. Theoretically, it is possible to create designs which form part of a protective housing, are in the shape of a mat that can be rolled up, or are even embedded into a carrying case or a piece of clothing. Such innovative batteries are still a few years away, especially for the commercial market.<p></p>

              <p></p>

              Unfortunately, the dry Li-polymer suffers from poor conductivity. The internal resistance is too high and cannot deliver the current bursts needed for modern communication devices and spinning up the hard drives of mobile computing equipment. Although heating the cell to 60°C (140°F) and higher increases the conductivity to acceptable levels. This requirement, however, is unsuitable for portable applications.<p></p>

              <p></p>

              Some dry solid Li-polymers are currently used in hot climates as standby batteries for stationary applications. One manufacturer has added heating elements in the cells that keep the battery in the conductive temperature range at all times. Such a battery performs well for the application intended because high ambient temperatures do not degrade the service life of this battery in the same way as it does with the VRLA type. Although longer lasting, the cost of the Li-polymer battery is high. <p></p>

              <p></p>

              Engineers are continuing to develop a dry solid Li-polymer battery that performs at room temperature. A dry solid Li-polymer version is anticipated by 2005. This battery should be very stable; would run 1000 full cycles and would have higher energy densities than today’s Li?ion battery.<p></p>

              <p></p>

              How then is the current Li-polymer battery made conductive at ambient temperatures? Most of the commercial Li-polymer batteries or mobile phones are a hybrid. Some gelled electrolyte has been added to the dry polymer. The correct term for this system is Lithium Ion Polymer. For marketing reasons, most battery manufacturers call it simply Li-polymer. Since the hybrid lithium polymer is the only functioning lithium polymer for portable use today, we will focus on this chemistry variation but use the correct term of lithium ion polymer (Li-ion polymer).<p></p>

              <p></p>

              With gelled electrolyte added, what then is the difference between Li?ion and Li?ion polymer? Although the characteristics and performance of the two systems are very similar, the Li?ion polymer is unique in that the solid electrolyte replaces the porous separator. The gelled electrolyte is simply added to enhance ion conductivity.<p></p>

              <p></p>

              Technical difficulties and delays in volume manufacturing have deferred the introduction of the Li?ion polymer battery. In addition, the promised superiority of the Li?ion polymer has not yet been realized. No improvements in capacity gains are achieved — in fact, the capacity is slightly less than that of the standard Li?ion battery. For the present, there is no cost advantage in using the Li?ion polymer battery. The major reason for switching to the Li-ion polymer is form factor. It allows wafer-thin geometries, a style that is demanded by the highly competitive mobile phone industry. Figure 1 summarizes the advantages and limitations of the Li-ion polymer battery.http://www.minamoto.com
