Use the formula: RPM = (60 * Frequency) / Number of Poles. How do you calculate RPM from linear speed? To calculate RPM from linear speed, you need to know the linear speed and the diameter of the rotating object. Use the formula: RPM = (Speed * 60) / (π * Diameter).
A rock crusher is driven by a 100 HP, hydraulic drive at 625 rpm. The nomial output speed must be 225 rpm. Design/select a roller chain drive. Specify the chain size, the sizes and number of teeth in the sprockets, the number of chain pitches, and the center distance. Check that the angle of wrap is sufficient on the small sprocket.

A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8. Estimate:

The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
A typical 24" diameter Double Roll Crusher has a standard roll speed of 150 rpm. This roll speed can be easily increased to attain higher throughput capacities by …

4. ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could …
First in the code the RPM is divided by 50 to get `crushingSpeed` and then speed is `crushingSpeed * 4`. So that bit stays the same. * the ternary operation, for all effective purposes, just does `log2(stackSize)`. * Then `processingSpeed` is clamped between 0.25 and 20, which is the same as the nested `MIN`/`MAX`.

Primary impactors should be of a solid rotor type to reduce maintenance costs. Impactors should have a connected horsepower sufficient to ensure 110% utilization. The crusher application, speed and setting are the factors affecting this. Impactors should be consistently fed based on the amperage drawn.
