Roll crushers reduce the size of the feed by crushing it between the two rolls, as shown in Fig. 4.7. These consist of two heavy cylinders revolving towards each other. The feed is nipped and pulled downwards through the rolls by friction on the surface.
Roll crushers used to crush rocks and other heavy-duty materials generally feature teeth or spikes along the surface of each cylinder. Smooth-faced cylinders are used to crush more delicate materials, including minerals and some metals. If the double roll crusher does not produce a fine enough material, a four-way roll crusher may be needed.
Tooth roll crushers are more efficient in crushing hard materials, while smooth roll crushers are better for crushing soft materials. Q: What is the capacity of a tooth roll crusher? A: The capacity of a tooth roll crusher depends on several factors, including the material being crushed, the gap between rolls, and the speed of the rolls.
With a Double Roll crusher, the material is drawn and forced between a large-diameter roller and an adjustable liner. The maximum size of material that can be fed to a roll crusher is directly proportional to the diameter of the rolls. Triple roll crushers are manufactured to provide two-stage reduction all in one crusher assembly.
The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
