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.

These parameters will vary depending on the specific design and manufacturer of the crusher. Calculate the theoretical capacity: The theoretical capacity of the crusher can be calculated using the formula: Theoretical Capacity = (Q / A) x V x 60. Where: Q = Crusher capacity (in metric tons per hour)

And, the "theoretical passing capacity of crusher" refers to an amount expressed by roll width x roll peripheral speed x crushing clearance of rolls x true specific gravity of feed material. So far, in crushing rocks or ores by a roll crusher, as shown in Fig. 14, crushing clearance S has been set smaller than the diameter F of feed particles ...

Hint: The theoretical capacity of a roll crusher is given by Theoretical Capacity of Roll crusher = (0.0034 *N'D'Wsp) Where, D = Diameter of roll (m) S = Spacing between rolls (m) B = breadth of the rolls (m) N = Speed of rotation (rpm) p= Density of material (2000 kg/m3) • Calculate the actual capacity of the roll crusher.

The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1 ); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is reduced by 39–40% [ 9 ].

The old Titan took up 4,352 ft2 in 200 cabinets and used 8.2 MW of power for a total of 17.6 petaFLOPS of sustained performance (27 petaFLOPS theoretical). The new Crusher needs only 44 ft2 in 1.5 ...

The theoretical capacity of the roll crusher is the weight of a ribbon of feed having a width equal to the breadth of the rolls, thickness equal to the gap between the rolls and length …

A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.

The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings, 3. options on feeding …
