Double Roll & Teethed Roll Crusher
The usual practice is to fit one roll entirely with so-called regular teeth, and the other roll with six rows of regulars and two rows of higher (slugger) teeth.

Roll Crusher operation is based on the principle of continuous pressure generated between two counter-rotating rolls; allowing uninterrupted crushing, in contrast to the intermittent action of jaw crushers.
Rolls were easy to manufacture, to install and to operate in a wide range of applications. A robust and reliable design, low machine height and an excellent ratio of capacity versus machine mass make double-roll crushers (DRC) still today the preferred choice for many soft to medium-hard rock applications in quarries and ore mines.
Combining a twin tooth rotor design and a single deck pre-screen allow fines to pass through either before the material reaches the chamber or by falling between the crushing rolls without being further crushed.
Lancaster Products Roll Crusher rolls rotate 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 crushing action.
Regardless of the tooth configuration or roll setting, the crushing principles are the same. Material is crushed as a result of the combination of impact, shear and compression. Despite the fact the rolls are rotating at a relatively slow speed, some material breakage occurs when feed material enters the crusher and is impacted by the crusher ...
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.
Hi, I'm a student and need to design a double roll crusher that can be used for crushing coal from 100 mm down to 50 mm at a rate of 300 tons per hour (tph). Where can I find the mechanical properties of coal and how do I determine the roll diameter, roll speed, torque and reaction forces on the shafts if the rolls have teeth?
