TAKRAF roll crushers are designed for capacities of up to 14,000 th and are driven by powerful drive units in order to even crush hard or ductile material without stalling. The crushing process creates a minimum of fines in the product and can also handle sticky andor wet material without clogging of the rolls. The machines can be employed for medium hard material types up to 200 MPa compressive strength for example coal, ore, limestone, overburden and oil sands.
TAKRAF has developed and successfully installed the largest roll crushers worldwide for the Canadian oil sands industry in order to guarantee highest throughput requirements under extreme conditions.
Roll crushers are often fed by apron feeders that direct feed material between a fixed and a moveable roll. The two crusher rolls, equipped with crushing segments, rotate inward and crush oversied material, while fine material passes the crusher without additional crushing. The adjustable gap between the crusher rolls defines the sie of product material that exits the other side and falls towards the outlet chute.
If tramp or oversied material is fed to the crusher, one hydraulically supported roll moveable roll will disengage or release temporarily to let the foreign material pass and then return to its normal position and resume operation. If the foreign material is unable to pass, the moveable roll will remain in its extended position while sending a signal to stop the feeding process. In addition, a safety coupling can also react in the event of shock loads.
Sep 02, 2019nbsp018332Double roll crushers offer up to a 3-to-1 reduction ratio in some applications depending on the characteristics of the material. Triple roll crushers offer up to a 6-to-1 reduction. As a compressive crusher, the roll crusher is well suited for extremely hard and abrasive materials.
Two heavy smooth faced chilled metal rolls turning on parallel horiontal axes are the working elements of the roll crusher. A hopper is provided at the top for feeding the material. Particles of feed caught between the rolls are broken in compression and drop out below. The rolls turn towards each other at the same speed.

1.The rollers is wear-resisting chromium molybdenum copper alloy with long service. 2.The gap between the rollers is adjustable, so that the output sie and capacity will be changed accordingly.3.This crusher is equipped with motorless scraper. When the raw material has high moisture content, it can avoid to affect the output sie and avoid sticking the roller or blocking the machinehe.4.According to requirement, it could be in flat roller or toothed roller.
how does a double roll crusher operate - Buon Gusto. Double Roll Crusher,Roll Crusher,Roll Crusher supplier. Double Roll crusher is mainly used for the crushing of medium or lowerhardness mines and rocks with medium or lower rigidity in mine selection, chemicals, cement and building materials industrial production.Roll crushers have a theoretical maximum reduction ratio of 41.
A heavy and rigid cast-iron frame supports the two-roll assemblies, each of which comprises a shaft, a roll centre, and a shell of wear-resisting metal, such as high-carbon steel, or manganese steel. Each roll is independently driven by a flywheel type, flat-belt pulley, or V-belt sheave. One of the two pairs of bearings is arranged to slide horiontally on the side frames.
These movable bearings are spring-loaded to provide a safety relief for excessive pressures, such as are caused by tramp iron, etc. They are drawn up against locating shims which establish the spacing between roll faces discharge setting, and are held in that position by the springs, which are pre-set to the working pressure for which the particular machine is designed. This working pressure may vary fromas low as90kiloper linear centimetre of roll face, for light-duty rolls, to as high as 5.3 tonne per centimetre of roll face for extra-heavy-duty rolls.
