As one of the most commonly used jaw crusher, blake jaw crusher has two types: Single toggle jaw crusher An eccentric shaft is positioned on the top of the crusher. The swing jaw plate hangs on the eccentric drive shaft and moves up and down in elliptical motion, which compresses rock material as it moves down from the feeding part.
The prediction of crusher performance is typically concerned with the size distribution of the product exiting the crusher, the machine's power draw, and the capacity. The capacity of a jaw crusher is dependent upon the operating characteristics of the machine and influenced by the feed size and the nature of the material.

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.
The BB 50 is the smallest model of the RETSCH jaw crusher series and has been specially designed for sample preparation in the laboratory.

The characteristics of HPGR products (such as more micro-cracks, higher grain exposure) are beneficial to the leachate's contact with copper-containing minerals to improve the leaching efficiency. Yin et al. (2017) compared the sample properties and leaching characteristics of gold ores from HPGR and jaw crusher.
be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-

Crusher Types and Operating Characteristics There are three basic classes of crushers, which, when restricted to the task of underground primary (large feed) crushing can be listed as follows: Pressure Crushers —This category includes gyratory and three types of jaw crushers.
The desired grizzly opening for an underground jaw crusher is equal to 80% of the gape of the crusher. Source: Jack de la Vergne; The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart; The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone …

A parameter study using a jaw crusher is designed to investigate the in fl uence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and the quality of the ...
The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.
2.2. Samples analysis after comminution2.2.1. Particle size distribution. The gold ore sample of 200 kg was first fed to the primary crusher (PEX-150 × 250 mm) and secondary crusher (XPC-60 × 100 mm) to ensure all the sample could pass through a sieve of 20 mm.The comminuted ore was then thoroughly mixed and divided, fed to the …
