Four Roll Crusher

 Adopt triangle belt driving between motor and reducer. The triangle belt will slip if load is too big, which can protect the motor. 

 The connection between the swing roller part and reducer adopts universal spindle coupling, which not only make sure the swing roller have enough adjusting range but also protect the motor and reducer in case that damage due to overload.

 The roller part is the hardcore part of the crusher. The connection between mill roller and main shaft adopts key and taper sleeve, which is dismounting easily.

The gap between two rollers can be read from staff. The place where there is a hole under the staff is the zero reference line. The gap is 10 mm when the machine leaves the factory. The client can adjust the roller gap according to requirement.

 The frame and base frame adopt box type structure, which is strong, safety and reliability. 

The workers can adjust the speed of two rollers through change the motor triangle belt. The efficiency will be good when the speed of two rollers is not the same, but roll skin wear faster.
