With the development of science and technology, the crushing equipment has been greatly improved in technology and also makes a breakthrough in the application of the equipment and materials. First, let’s talk about the plastic material.The material has the advantages of small specific gravity, strong corrosion resistance, good wear, friction performance and seismic resistance. In addition, the plastic material has sufficient mechanical strength, which can be compared with the metal material. In recent years, the proportion of plastic parts in military and civilian machinery products increased. Many countries have drawn up the plastic standards for the industrial sector selection.The moving jaw bear of the simple pendulum jaw crusher made in Japan uses the oily synthetic resin. The plastic is used to make the machine parts, which not only can save the metal to reduce weight, but also improves the performance of the machine to improve the reliability of the machine, extend the service life of the machine and reduce the production cost of the machine.The second material used in mining machinery is rubber. After years of trial studies. it confirms that the wear of the smooth manganese steel liner is twice faster than the flat rubber liner wear. The ribbed rubber liner wear occurs only at the top of the ribs, while there is no wear between the two tendons. The amount of wear of the rubber layer of the smooth rubber village board and a ribbed rubber liner within a unit time is equal. The consumption of ribbed rubber liner for per ton of material is only one-third of the smooth rubber liner. The wear of the rubber changes with the size, speed, and the hardness of the material of the device. The test in Sweden has demonstrated that the cost of the liner reduces by 5% after the discharging end of the mill, feeding end and the carcass use rubber liner. In addition, the installation time is 2.5-3 times faster than the manganese steel. Meanwhile, it is possible to reduce the power consumption and weight of the machine, and to reduce the consumption of grinding bodies to extend the life of the liner. There is no noise when the mill is running, which can improve the working conditions. When the rubber liner is used to replace the steel liner, you can not use the wood or steel to fill with the cracks. The rubber liner must be connected. At the connection of the carcass and end liner, you should fill with a piece of rubber. The remaining gap should bu filled with cement. As the rubber sheet is easy to burn, so the installation work should be completed in the case of entirely fireproof.
