Below are suggested speed guidelines for CMB Cone Crushers: Low speed: Secondary applications, after a Jaw Crusher. Medium speed: Gravel applications with coarse feed. Standard speed: Tertiary applications (0 x 1/2") High speed: Sand applications (4m or less) Speed ranges: Smaller head diameters (48" or smaller): 750-1,200 rpm.
Standard (Secondary) Cone Crusher (Refer to Fig. 1): The Standard Cone crusher is normally applied as a secondary crusher in a multi-stage crushing circuit. The small diameter feed distributor and the wide throat opening at the top of the liners enable the Standard Cone crusher to accommodate the larger feed produced by the Primary crusher.

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
