　　Working Principle of mobile crushing and screening units

　　When the mobile crushing and screening units is working, the motor drives the eccentric bearing bushing via spring coupling, transmission shaft and a couple of cone gear wheel. The crushing cone axis is forced to swing by the eccentric bearing bushing, which makes the mantle sometimes close to the bowl liner, and sometimes far away from the bowl liner. The raw materials are pressed, impacted and finally crushed in the crushing chamber.mobile crushing and screening units When this mobile crushing and screening units works, driven by the motor, the rotors revolve in high speed. When the materials get into the machine, it pumps the flat hammers of rotors, then the materials fly to the impact plate rapidly and pumps the flat hammer again, immediately, the materials are rebounded to the area of flat hammers. This process repeats constantly till the materials reach the required size and is discharged from the outlet.
