Rock Crushers. The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand 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
HAZEMAG’s double-shaft hammer crushers, with efficient 3-stage crushing operations, are mainly used in the cement industry for the comminution of soft to medium-hard material. READ MORE Roll Crusher | …
Jaw Crushers are used to reduce the size of many different types of materials in many applications. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers
Knowing that the double roll crusher won’t apply extremely high or low strain rates to the particle, one may reasonably choose that a particle of hard rock can withstand 100 MPa of stress and require between 50 and 250 Joules of energy to break depending on its size. This rationale served as the basis for defining the main design criteria

Double roll crusher ... series roller crusher is widely used in tertiary crushing with the material feeding size less than 30mm and the product size 1 - 10mm of artificial sand making (cobblestone and construction waste), ... The tyre pressures are varied to suit the roll centre adjustment
Double roll crusher technology redefined. Comminution with a Crush + Size crusher is based on the innovative, patented crushing tool design. It enables the use of very high teeth with a small crushing gap, so that a direct feed of the feed material is ensured with a high crushing ratio at the same time. The oversize grain is effectively avoided in all three dimensions by a crushing chamber limitation and …
Roll diameters and widths are dictated by the feed size, product size and capacity. The rule of thumb for the Double Roll Crusher’s ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance
May 28, 2015 · When users need to adjust the crushing particle size and output amount, we must adjust the adjusting bolts and lock nuts on both ends of the fixed roller, adjusting ways are as follows (take example of double roll crusher 2PG series in Great Wall Heavy Industry Company):
As shown in Figure 4.24 the double-roller crusher consists of two horizontal cylinders that revolve toward each other at the same or different speeds. One of the rollers is springloaded and the other is permanently mounted. The rollers can be gear driven but this limits the distance adjustment between the rollers. Most rollers are driven by V-belts using individual motor

Feb 24, 2016 · 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
【Main parts】Bearing box, roll shell, bearing housing, adjusting rod, motor, carrier, fixed roller, movable roller and safety spring, etc. 【Working Principle of Double Roller Crusher】The roller of the roller crusher is supported by the spring pressure.Under normal working conditions, the spring force is sufficient to overcome the crushing force of the crushed material
8″ Double Roll Crusher. US $ 7,000. ... The smaller size crushers are furnished for belt drive or motor drive and with either of these drives provision is made for hand operation if desired. ... The springs are held at any desired tension by lock nuts and the machine may be dismantled without changing adjustment of the springs. Roll alignment
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 crushers can adjust the wedge device between rollers to control the feed and discharge size of the machine
