Formula For Crushing Rollers

roll crushers - slideshare,double roll crusher working principle and structure of double roller crusher 1.this series of roll crusher is mainly formed by the roller, roller support bearing, compression and adjusting device, drive components etc. 2.the adjustment of the particle size: between the two rollers equipped with adjustment device like pads or wedge.the wedge-shaped device has a adjusting bolt on top, when the adjustment bolt pull up the wedge, the wedge will push the movable roller away from the fixed roller.rolls crusher for sale - 911 metallurgist,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.

Diameter Of Rolls For A Roll Crusher For The Given Feed

Diameter of Rolls for a Roll Crusher for the Given feed

the following formula relates the coefficient of friction ( m ), radius of rolls (r), radius of product (d), and radius of feed (r): cos a = (r + d) / (r + r) à 1. where a is related to the coefficient of friction by the relation, m = tan a. angle of nip = 2 a.
