A typical jaw crusher can accept boulders that are about 75-90% of the size of its gape (the distance between the jaws at the feed opening), which, for large crushers, can be up to 48 inches wide. Through the use of compressive force, the Jaw Crusher reduces these large boulders into pieces roughly 6 to 8 inches in size.
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.
The force transmission characteristics can be used as criteria for the comparison of different jaw crusher mechanism designs in order to select the most suitable design for a given application.

jaw crusher attachment. Keywords Jaw crusher, Kinematic analysis, – Dynamic analysis I. INTRODUCTION Rapidly growing rate of industry crushing machinery. A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism.
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.

This paper studied the liberation characteristics of middlings crushed with different kinds of fragmentation forces. Middlings of −3 mm + 0.5 mm sampled from a dense medium cyclone were comminuted by a jaw crusher and a ball mill to −0.5mm with similar size distribution respectively. The generating mechanism of fines was also analyzed.
The design and development of a new generation high crushing capacity jaw crusher, developed for the first time in Turkey and whose Closed Side Settings (CSS) may be automatically adjusted hydraulically, were investigated in this study. The calculations for the crusher developed for this purpose were included in the paper. The design modifications …

However, a bigger CSS will produce a coarser product. Compared to jaw crushers, cone crushers have a higher reduction ratio, usually between 6:1 and 8:1 in a single pass. They also make a more cubic and evenly-shaped product because of the interparticle crushing action that happens inside the crushing chamber.

A gyratory crusher is a type of crusher that uses a mantle to guide the crushing process. The mantle is suspended on an eccentrically rotating shaft, which causes the mantle to gyrate. The gyratory crusher has a higher capacity than a jaw crusher. It is often used for primary crushing in the stone crushing industry.
They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece. crusher is famous product of heavy industry. An important parts of jaw crusher: moving jaw plate.
