Reduction Ratio Calculator
Mathematically, the reduction ratio is calculated by dividing the size of the feed material by the size of the product. For example, if the feed material has a size of 100 millimeters (mm) and the product size after crushing is 20 mm, the reduction ratio would be 5:1 (100/20 = 5). This means that the crusher has reduced the size of the material ...

How To Size A Jaw Crusher
For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54". By sizing the Jaw Crusher slightly larger than the largest feed size, you reduce the risk of large lumps getting stuck in the crushing chamber or sitting on top of the crushing chamber, stalling production.

Feed should always be well graded with no gaps in the size distribution, which generally means an even distribution of different-sized feed material up to the defined maximum size. Fines (for example, 0–4 mm) should be screened out before the material is fed to the crusher as the fines may cause packing: this is a force overload and can be ...

How Ball Mill Ore Feed Size Affects Tonnage & Capacity
The rod mill was needed to reduce feed size to the ball mill because crushing plant output was normally coarser than 80% passing 10,000 microns. Such feed causes power inefficiency if fed directly to a ball mill. Even though the rod mill could be a relatively inefficient device for both energy and metal consumption, as was evidenced by …
