2.1 Roll Crusher Geometry It is necessary to estimate the maximum size of the mineral particles that can be fed into the machine for a known roll diameter, roll length and roll gap. It is convenient to assume that the particle is spherical and the roll surfaces are smooth when calculating for the maximum size of the particle feed.
How to calculate the Roll Crusher Capacity using a Formula The theoretical capacity of crushing rolls is arrived at simply by calculating the volume of the ribbon whose cross section is the area of the discharge opening, and whose length is the peripheral speed of the roll faces per unit of time.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
On the right, a Roll Crushers is shown in a sectional elevation of the A-C single-roll crusher while here below is a cutaway view of the machine, with hopper and part of the near side frame removed to show the crushing chamber. The moving elements of the machine consist of the roll, with its supporting shaft and driving gear, and the pinion-shaft on which are mounted the pinion and driving pulley.

Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. 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 expect from the crusher is 1/2 inch. Roll ...
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).
