Two Roll Crusher
It only has a pair of opposite rotating rollers, completing crushing in one single pass. Materials are squeezed and crushed once through fixed roller gap, then discharged directly. Only one-time extrusion process, simple structure, single crushing effect, limited crushing fineness adjustment range.
Three Roll Crusher
It is designed with vertical three rollers to form two crushing zones, realizing two-stage continuous crushing.
- Upper two rollers finish primary coarse crushing
- Materials fall down and enter the lower roller group for secondary fine crushingIt uses one shared middle roller to save space, with adjustable bottom roller gap.Double extrusion process makes particle size finer and more uniform, and it is equipped with spring overload protection.
Core Principle Differences
- Crushing timesTwo roll: one-time crushingThree roll: two-stage successive crushing
- Roller layout & functionTwo roll: only one group of working rollersThree roll: upper group for coarse crushing, lower group for fine crushing
- Particle forming effectTwo roll: coarse finished granules, uneven size, more powderThree roll: fine and even granules, low powder rate
- Material processing wayTwo roll: simple direct extrusionThree roll: differential speed extrusion + secondary refined shaping
- Application principle orientationTwo roll: mainly for rough primary crushingThree roll: dedicated for fine crushing and uniform granulation of feed raw materials
