Working principle
Hydraulic roller crusher consists of a couple of parallel cylindrical rollers which are fixed horizontally. When these 2 rollers rotate in opposite directions, the fed material fall down to the rollers, and will be brought into the middle of the two rollers by friction and gravity, crushed and grinded by the two rollers and at last broke into small pieces. The crushed stone is pushed by the rotating roller and discharged by gravity.
