The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and even above. It is less sensitive to wet and sticky material than Roll Sizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks.
Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate. ... The shape of the teeth is generally pyramidal. The roll surfaces play an important part in the process of nipping a particle ...

The Steele Smooth Roll Crusher plays a key role in bulk raw material preparation, processing clays, coal fines, coke breeze and gypsum waste. Twin rollers reduce pebbles and plastic lumps to form thin, flat discs, strips or sheets of material for additional processing or pugging. Crushing and shearing improve mix quality, so we use a twin …
A toothed double-roll crusher (referred to hereafter as TDRC) consists of a pair of oppositely rotating rolls, which have a series of intermeshing teeth protruding from the roll surfaces. The crushing action of TDRC is a combination of compression and ripping, where the teeth can dig into the rock and larger pieces than the roll diameter can be ...

The EDGE RS1500 roll sizer has been designed for the secondary and tertiary crushing of medium-hard, sticky and soft materials such as coal, lignite, clay, limestone and other bituminous and sub-bituminous materials. Boasting an impressive list of design features that includes a highly efficient hydraulic drive system, easy selective piece ...
Tooth roll crusher, also known as double roll crusher, is a versatile equipment used for material reduction in various industries. It consists of two cylindrical rolls that rotate in opposite directions, with each roll containing teeth that interlock with the teeth on the opposite roll. As the material is fed into the crusher, it gets crushed ...

But, when rolls' speed exceeds 150 rpm, the crushing performance would not be significantly improved. A reasonable working gap and better nipping behaviour are obtained using the spiral-tooth-roll or the staggered-tooth-roll. The validated DEM model could be applied to gain a fundamental understanding of the crushing mechanisms of TDRC.

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.
The Single Roll Crusher, which was originally patented by Calvin McLanahan in 1894, has evolved over the years to include design features to ensure many years of rugged operation. Complete with all safety guards, the Single Roll Crusher features an automatic tramp relief mechanism that allows the crushing plate to hinge open, pass non ...
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 producing a cubicle product at high capacities. An intermeshing tooth design means that no timing gears are required.
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 ...
