The rule of thumb for Jaw Crushers is to select a machine with an opening distance from the front of machine to the pitman (called gape distance) that is 20% larger than the largest particle size. Another way of stating this is to say that a given crusher size should be fed material with a largest particle size no greater than 80% of the gape distance.

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.

· 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
