One of the main functions of the spring loaded loose roll is to use the springs to absorb the initial shock loads when non-crushable material is fed into the crusher. This together with a V-belt drive system, helps protect the geared motors, bearings and shafts from shock load damage.

Roll crusher, also known as roller crusher, belongs to traditional crushing equipment. It is mainly used for fine processing of material particles. As the main working part, the two cylindrical rollers rotate oppositely to achieve the purpose of crushing. Due to its peculiar tooth crushing structure, it …

Apr 24, 2015· ROLL CRUSHER  Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing.  Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1.

The laboratory roll crusher consists of machine body, rollers, and other components. The spindle drive by V-belt from the motor, the roller operate according been turned trajectory, crushing the materials in the crushing chamber. Mini roller crusher is equipped with an adjustment screw in front and rear.

A spring-loaded mechanism works similarly when the contact between the rollers uncrushed body. Dual spring package provides increased speed of the roll, allowing you to skip almost any possible uncrushed body. In the proposed design, the force of the power element package of the spring is transmitted through the beam directly on the rack.
