Use a crusher with the right roll diameter with respect to the desired input and output size. Large pieces of coal fed to small diameter rolls produce a rolling effect of the coal as the teeth battles to grip the coal, thereby reducing throughput tonnage and increasing fines and segment wear.
One roll is fixed while the loose roll is spring loaded to minimize shock loads and damage to the crusher during a stall, resulting from noncrushable material, mostly tramp steel, being fed to the crusher.

Double Roll Crusher 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.
Single roll crushers utilize machine cut teeth on the gear set between the roll shaft and countershaft. Gear teeth are designed with a wide face and large profile for maximum strength and power transmission. With the exception of the Cobra Single Roll Crusher, all gearing is cut from alloy steel.
Crushers are also classified by their method of mechanically transmitted fracturing energy to the rock. Jaw, gyratory, and roll crushers work by applying compressive force. Impact crushers such as single rotor and hammer mill apply highspeed impact force to accomplish fracturing Table 2 (T 142, Text) lists the major types of crushers. CHAPTER 14.
