In the design, movable jaw plate and fixed jaw broken teeth should peak to valley teeth. Thus, when the broken material in addition to the role of external squeeze hammer crusher, and bending of the material relatively easily broken. In order to enhance the life of broken plates, small plates designed crusher broken down into a symmetrical shape, after a moment can turn around and use the Department of wear; a large jaw crusher crushing plate designed to mutually symmetrical pieces, so wear can post Use the broken board swap. Broken plates can choose white cast iron materials. White Iron greater hardness, good wear resistance, easy to source cheap; drawback is brittle, easily broken, life is short. In order to improve the life of the breaker plate, the material with the above 12% manganese steel manganese better, commonly used ZGMn13. Manganese better toughness heavy hammer crusher, although not high hardness (about 210HB), however, because it has the characteristics of work hardening, under pressure will continue to be strengthened, so wear at work constantly and constantly strengthen the hammer crusher manufacturers, it can not be used until worn to be scrapped. Manganese steel cast after going through a breaker plate water toughening treatment, the operation is substantially the same as the quenching water toughening treatment, i.e., the casting out of the manganese steel breaker plate heated to 1000 ~ 1100 ℃ quickly cooled in water. After the water treatment can be tough uniform microstructure, and microstructure fixed, avoid the use of naturally occurring in the phase transition leaving poor performance. Disadvantages manganese is more expensive, but life, cost and other aspects of general considerations, ZGMn13 than white cast iron long life, low cost. We know that hammer crusher production, with the continuous progress of the market economy and the continuous development of science and technology, China's various industries are in constant development, we all know that China is a big country in mineral resources, rich in mineral resources, mineral resources and these The exploitation and utilization, development is inseparable from the crusher equipment. Huge market demand in the market has a large number of required support equipment for mining, especially large crusher equipment to meet the large-scale production and lower electricity costs broken, for example, require lubrication systems and control systems for more than a small model of the device Strict.
