formula for crushing rollers Capacity Roll Crusher Calculationsroller Crusher Roll Power And Capacity For Mercial Roll Crusher Roll Crusher An Overview Sciencedirect Topics The capacity of the singleroll crushers is a function of the roll gap the roll length and the speed and ranges from about 30 tonsh 27 metric tonsh for a 24inchlong 61 cm

The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening and whose length is the peripheral speed of the roll faces per unit of time The formula for material weighing 100 lb per ft3 is D x W x S 48 TPH

crushing Top roller is critical component amongst all As the drive torque hydraulic load crushing load is coming on the top roller The forces acting on the mill rolls give rise to shearing bending torsion and compressive stresses The top roller is most highly stressed since it

The concept of crushing using the crushing roller mill includes even more technical features Apart from the counterrotation of the two rollers there is a differential speed of the roller pair The crushing is achieved by a combination of shear stress cutting and pressure A special corrugation of the rollers contributes to the crushing of
