DESCRIPTION. Osborn Double Roll Crushers can be used for primary and secondary crushing. The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher; however in some instances dependent upon material friability and hardness it is possible to achieve a 6:1 crushing ratio.
Double Roll Crusher. Double Roll crushers are the most common type of roll crushers. The crusher machine uses two opposite rotating rollers to crush the material. It is composed of an electric motor support a fixed roller a movable roller a safety spring etc.
The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher however in some instances dependent upon material friability and hardness it is possible to achieve a 6:1 crushing ratio. The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency

A Double Roll Crusher is based on the principle of feeding the material to be crushed between two manganese steel cast rollers rotating in opposite directions with their axes parallel to each other. The gap setting between the rolls is very small and hence the feed material is crushed while it passes through them.
Toothed Double Roll Crushers are used for crushing of friable and brittle materials like Coal Coke Sinter hot and cold Clay Earth Slag Chalk Soft Limestone etc. Due to cutting action of the teeth crushing of material takes place mostly due to shear and not by pressing. Therefore fines generation is bare minimum. Description: Crushing takes place due to two rolls running in to each ImagesMore results in images
Triple Roll Crushers. Triple Roll Crushers are ideal for producers who want to accomplish two stages of reduction in one pass. They can be used in coal salt coke glass and trona operations among others. Triple Roll Crushers combine a Single Roll Crusher with a Double Roll Crusher to form a crusher that is capable of achieving a 6:1 reduction ratio in the primary stage and a 4:1 reduction

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.

Roll Crushers rely on a combination of impact compression and shearing action to break material along inherent fracture planes. The Double Roll Crusher is ty
Sometimes a plain rolls are also used for crushing.Protection of un crushable material is provided to one of the crushing rolls in the form of a retractable roll mounted on heavy duty springs. This retractable roll assembly automatically widens the gap between the rolls during the entry of un crushable material and again come back to the original position.Operation of Double Roll Crushers is
In the double roll crusher the feed is distributed by a feeder over the entire roll width. The material is drawn into the crushing gap by appropriately shaped teeth projecting from the rolls. For special appli ions teeth of different heights are available at option. The anticipated maximum feed size determines the roll diameter.

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 appli ion in handling friable sticky frozen and less abrasive feeds such as limestone coal chalk gypsum phosphate and soft iron ores.
Double Roll Crusher. Double roll crusher is a relatively old crushing equipment. After numerous upgrades and transformations the manufacturing process is more mature. The equipment has a simple structure and less over-crushing. The tooth shape size and arrangement on the roller surface can be changed according to the nature of the material.
