Crusher Reduction Ratio Mineral Processing & Metallurgy

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Impact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material.

Impact Crusher Working Principle

Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping

The size reduction takes place quickly along short fracture lines, producing a more cubical product to meet aggregate specifications. This fast impact fracture is different from the slow compression breaking in cone or jaw crushers that produce more slabby or flat material (5 to 1 length to height ratio).

Impact Crushers Primary | McLanahan

Impact Crushers create material reduction by providing a sudden impact force that causes the material to shatter along all the weakest fissures in the stone. Controlling the flow of the material through the Impact Crusher requires features that vary from one style of impactor to another, and this is what separates McLanahan from the other

Size Reduction Visual Encyclopedia of Chemical Engineering

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher , also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device . As the disc rotates, the feed material is struck and crushed by descending

Impact Crushers have a Reduction Ratio of approximately 15:1. An example of this ratio of reduction would be that a 30” input particle can be reduced to approximately a 2” discharge particle.

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Cone Crushers | McLanahan

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may
