He outlines three simple rules behind properly sizing a jaw crusher. Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size should not exceed 80% or 24-in.

The effect of crusher feed size on product sizing is shown in Figure 6 page I-196. For a constant setting or gap, the product % coarse is directly related to the feed % coarse. In other words, the shape of the feed size distribution is reflected in the product distribution. Other measurements have shown that the medium size material is largely

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates.

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".

Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material. Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches).

The capacity is similar to that of a jaw crusher with the same gape, and breadth 'B' equal to the perimeter of the gyratory crusher. Since all the coarse crushers have greater capacities than the devices for the finer ranges of size reduction, a gyratory crusher of sufficient size to crush the required size feed may have an excessive capacity.
