The appearance  of  crushers is  to meet  the market  of  mining  material  process. According to the various request of quality of mine materials of diverse industries that increasingly need mining process, the machine and technology used in process are different. The appearance of mobile crushing plant is to meet the industries of great liquidity that contain uncertain factors as today is to east and tomorrow is to west, which is common, and the more industries of high liquidity exist, the bigger the market of mobile crushing plant will become.   The industries of high liquidity which we often come across, like the construct of roads require the mobile crushing plant have the following features: reasonable allocation in various crushing equipment, high speed of produce, convince in function and operation, great combination with materials location or working location, superb performance of operation, satisfying the need of different materials and portability and ease of assembly.   Now the main constituent of the mobile crushing plant includes primary crushing plant, second level crushing and screening plant and belt conveyor, which constitute the main part of the plant, meet the industries of high liquidity, crush materials in work site, reduce the fee of  transport of different materials and this kind of machine is convenient and flexible, and enjoys great mobility which becomes a good choice for many trades, and there is a great development prospect for this kind of mobile portable crushing machine.
