Engineers change the packaged technology, so that each node can control system and transfer the information to the central nervous system. Then, Environmental elements are fitted in production technology and mining equipment is becoming ecological. The requirement of ecological mining machine is low noise, low dust and high safety. For example, the complete set of mining machinery include 69 jaw crusher, PF1214 impact crusher, vibrating screen, belt conveyor, ect.. Each node needs to be dust and noise, the noise big equipment should equip with sound insulation room. Stone crusher with big dust should also be closed and dust cleaners take out to collect dust.Qualified aggregates entail good equipments. The performance of the mining machine has a direct influence on the sandstone quality, which raised a higher requirement of crushers. Currently, Chinese crushers are developing in the direction of more advanced technique, higher quality, better performance, longer life span to meet the increasing market demand. The hard stone is usually the excellent aggregate in the highway construction. So it is quite urgent to solve the problem of the hammer abrasion. The common layout now is "jaw crusher-cone crusher-impact crusher-vibrating screen" of which the idea is to use the impact crusher for shaping after the stone has been crushed to a suitable fineness by the cone crusher. This idea entails a bigger initial investment while reducing the further cost of wearing parts. It is perfect if you are producing stone and sand both while less cost-efficient for those who only produce stone material.Crushing equipments are widely applied in innumerous fields like mining industry, the metallurgy, construction materials, highway construction, railway construction, water conservancy and chemical industry. The common mining equipments include the jaw crusher, the impact crusher, the cone crusher, the vertical shaft impact crusher, etc. Generally speaking, the cone crusher features its...
