Suppose we have a roll crusher with the following parameters: Using the formula: Capacity = (2.5 * 0.5 * 1 * 0.05) / (2 * 10 * 200) Capacity = 0.0625 / 4000 Capacity = 0.000015625 cubic meters per second. So, the calculated capacity of the roll crusher is approximately 0.000015625 cubic meters per second under the specified conditions.

Abstract Analytical method for determining the energy-power parameters of the crushing process in a rotary hammer crusher with a grate is proposed. Using the method of equivalent power required for the electric motor drive of the crushing machine at the steady mode of operation and basic laws of general mechanics, we explain the …

Jaw Crusher: 500 mm to 800 mm: Reduced to about 125 mm to 150 mm. Large chunks of material are fed into the jaw crusher where strong compressive forces break them down. Secondary Crushing: To refine the size of the materials from the primary crushing stage. Cone Crusher, Impact Crusher: Usually between 125 mm and 150 mm: …

Double roll crushers help producers achieve the strict coal specifications they need to meet. Used as a primary or secondary unit, double roll crushers can be used in nearly any application with even the hardest, most abrasive material. This efficient crusher can lower power requirements for producing material and, with its unique features, can ...

Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls ... called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it ...

With a Double Roll crusher, the material is drawn and forced between a large-diameter roller and an adjustable liner. The maximum size of material that can be fed to a roll crusher is directly proportional to the diameter of the rolls. Triple roll crushers are manufactured to provide two-stage reduction all in one crusher assembly.
