A cement manufacturing unit uses a set of crushing rolls to crush dolomite (specific gravity =2.85) from a maximum feed size of 6.5 cm to a product size of 1 cm. The rolls with a width of50 cm run at 90 rpm and have a clearance of 1 cm between them. If the angle of nip is 30°,find the diameter of...

Figure 2. Roll crusher diagram Theoretical Capacity of Roll crusher = (0.0034 * N * D * W * S * ρ) tons/hr N = Number of revolutions of the rolls, RPM. D = Diameter of the roll, inches = 8" W = Width of a roll, inches = 5" ρ = Density of the crushed ore, gram/cm3 GRINDING: Grinding is the last stage in the process of comminution.

A certain set of crushing rolls has rolls of 100 cm diameter by 38 cm width face. They are set so that the crushing surfaces are 1.25 cm apart at the narrowest point. The manufacturer recommends that they may be run at 50 to 100 r.p.m. They are to crush a rock having a specific gravity of 2.35, and the angle of nip is 30.

The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio.

Theoretical capacity of crushing rolls in tons/hr is given by (where, V = peripheral velocity, m/sec. W = width of rolls, m Dr = distance between rolls ρ = density of material to be crushed, kg/m3 here, V =πND where, N = speed of the rolls in rotation per second (rps) D = diameter of rolls, m) ?

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 crushing to ¾ inch (2 cm), up to approximately 1500 tons/h (1360 metric tons/h) for an 84-inch-long (213 cm) roll crushing to pass 10 inches (25 cm).

Capacity of Roll Crushers. The capacity Q of roll crushers is directly proportional to its width, W, diameter, D and speed of revolution of rolls . Under continuous and steady feeding conditions, the capacity is given by (6.5) Q = π 60 D W ω L ρ B = 188.5 D W ω L ρ B t / h. where D = diameter of roll (m) W = width of roll (m) ω = speed (rpm)
