The rolls are operating with 5 m/s or more and shear and compression forces crush the material between the roll in the gap. The crushed material is released through the crusher base frame onto a discharge conveyor. The floating roll enables the crusher to release tramp metal and adjust the gap by the hydraulic supported gap setting system.

Due to differences in roll rotation rate and teeth distribution on roll, breakage product of SC shows the lower yield of +50 mm particles and −6 mm fines, and the higher content of −50 + 6 mm progenies. SC also indicates the advantage of saving energy if compared with that of single tooth roll crusher and double teeth roll crusher …

Roll Crushers. Similar to Sizers, Roll Crushers can be used for the primary crushing of soft to medium hard material that can be slightly abrasive, dry, or wet and sticky. They are typically used in heavy mining applications and have a typical ratio of reduction of 4:1. Primary Roll Crushers are available in several designs:

In coarse comminution, double roll crushers (DRC) are used for the size reduction of blasted materials and in secondary comminution. In the primary crushing stage, DRC with toothed rolls are of particular importance. In contrast to smooth rolls, these offer improved nip conditions so that larger particles can be nipped, and crushed.

Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

Double teeth roll crusher is mainly used in mining, metallurgy, chemical industry, coal mine to crush coarse, medium size fragile material. Its feeding size is big, discharging size is adjustable. it can crush material of compressive strength below 160Mpa. Especially in coal industry, double teeth roll crusher can crush raw coal and coke directly after …

The breakage behaviour of coals in the industrial sieving crusher and ordinary teeth roll crusher was compared based on industrial scale tests, in which both the consumed energy and the product ...

Roll crushers with differing tooth configurations can handle feed material of up to 1500 mm to generate a product of some 250 mm at rates of up to 2500 t/h. Roll crushers with smooth rolls are used for pulverization to generate a product granulometry of ≤ mm. ... Thanks to the distinctive geometry of the roll surface, i.e., teeth, hard facing ...

Double roll crushers help producers achieve the strict coal specifications they need to meet. Used as a primary or secondary unit, double roll crushers can be used in nearly any application with even the hardest, most abrasive material. This efficient crusher can lower power requirements for producing material and, with its unique features, can ...

The Twin Roller Crusher (TRC) is designed for flexible particle size reduction of soft to hard materials, which can be dry, or slightly wet and sticky. For materials such as coal, coke, cement clinker, limestone, …

Depending on the duty class, they can be used in most ROM applications, such as coal, salt, lime, pet coke and potash operations. 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 in the secondary stage while …

Lancaster Products Roll Crushers reduce – in a single pass- material previously requiring primary and secondary crushing. 800.447.7351. ... The crushing rolls turn toward each other, confining all crushing to the area where the teeth mesh. Both rolls are timed to rotate at the same speed to maintain a true – and highly effective ...

Working concept. Magaldi Single-Roll Crusher features a toothed roll assembly, which crushes the incoming feed material against anvil plates. When the material enters through the inlet chute, the teeth of the rotating cam shear and split the chunks against the anvil plates.
