• ### singletoothed roll crusher

Conventional single-roll crushers use a simpler toothed-roll design, and are commonly used to reduce coal to approximately 2–3 inch (5–8 cm) topsize. The capacity of the single-roll crushers is a function of the roll gap, the roll length, and the speed, and ranges from about 30 tons/h (27 metric tons/h) for a 24-inch-long (61 cm) roll

• ### diameter of rolls for aroll crusherfor 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. We have, m = 0.29. Therefore, a = tan-1 (0.29) = 16.17 o. And we have, d = 0.5 cm; R = 1.5 cm
