RETSCH supplies eight different types of jaw crushers, and each one accepts different feed sizes and delivers different results in terms of final fineness. All models of jaw crushers have a superior throughput and give a superior degree of size reduction relative to their intent and size. Each model also provides good quality final fineness.
The amount of pressure applied and the duration of its application influence the fineness of the grind. This technique is commonly used in jaw crushers and in mortar grinders. The effectiveness of this method depends on the hardness of the material being ground, the grinding surfaces, and the specific application of force.

Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high reduction efficiency. Jaw crushers are normally capable of a reduction ratio of 1:2 or 1:3. This ratio is affected by the feed
applied to obtain the required fineness. Large particles cannot always be ground to analytical fineness in one step. In some cases it is possible to carry out coarse and fine grinding in the same mill with different settings; in other cases two mills or crushers are required. 1. Why Size Reduction
