As the term "primary" implies, primary crushers are used in the first stage of any size reduction cycle. Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the
Working Principle of Double roll crusher. A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.
Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds.
Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions.
The Working Principle of Roll Crusher. Double-roll crusher can be divided into high speed and low speed double-roll crusher according to the revolving speed of roller; According to the installation methods of roller, it can be divided into two kinds: a roller bearing is active, and the other bearings is fixed and two roller bearings are active
Operation Principle. Double roll crusher is driven by the motor through the pulley or gear shaft opposite two rollers rotate, or were driven by two motors rotate two rollers. Double roll crusher with material by weight and the friction between the roll surface into the crusher and discharge within the broken. Through changes in two double roll
Roll Crusher Working Principle. Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum, phosphate

The crusher has hood seals on the hood sides, which seals the crushing chamber to prevent dust escaping. The crusher is supplied with a V-belt drive, a guard and a drive stand. A pair of geared motors drives each roll independently. Both drives are situated on the same side to make the crusher more compact.
Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions.
DOVE Roll Crusher also referred to as Double Roller Crusher, or Twin Roll Crusher is highly efficient crushing machine, used in certain applications for primary, secondary and tertiary crushing applications. DOVE Roller crushers are highly practical crushers for soft to medium-hard ore and where the final crushed out put is required to be of

Double roll crusher works on the principle of compression force. It can easily give a reduction ratio of up to 5:1. The material to be crushed is fed between two manganese rollers (rotating in opposite directions) through a feed chute and discharged at the bottom.

Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary
