In terms of medium and fine crushing, jaw crushers are mostly selected for small output. Otherwise, choose a cone crusher. Feeding mouth width greater than 600mm is a large-scale crusher, feeding mouth width 500-600mm is a medium-sized crusher, and feeding mouth width is less than 500mm is a small crusher. The jaw crusher has a …

and eliminate high starting currents. The electricity used to power the crusher motor will vary depending on the required particle size: the smaller the particle the more electricity is used in crushing it. Using AC drives for crusher motor speed control provides an effective way to meet the smooth starting and crusher motor speed variations.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.

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".
