While there are many different kinds of jaw crushers on the market, two types are predominantly used: the single-toggle jaw crusher and the double-toggle jaw crusher. Single-toggle jaw crushers, a seemingly simple yet complex mechanism, have a swing jaw which moves in an elliptical path from the bottom to the top of the crushing chamber.

Cone crushers, on the other hand, are more often used in the secondary and tertiary crushing stages. After the jaw crusher has done the primary crushing, the material gets fed into a cone crusher to be made even smaller. Sometimes, several cone crushers might be used one after the other to get the product to the desired size and …

The jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. The …

Double toggle movement jaw crushers like the Blake style (named for the inventor of the first successful mechanical jaw crusher, Eli Whitney Blake) have long been the standard for crushing hard ...

A double toggle jaw crusher is much larger, heavier, more moving parts and lower throughput than modern single toggle jaw crushers. The lower throughput statement is a bit misleading because it's partially attributed to the type of bearings they have versus modern crushers, so if one was to upgrade the bearings, throughput could …

The primary optimization objective was productivity, while crushing force served as an auxiliary optimization objective. These studies improved the performance of the crusher, leading to better ore crushing outcomes. As to jaw crushers, Legendre and Zevenhoven (2014) conducted an energy efficiency study.

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 price of double toggle jaw crusher is from 50,000 to 200,000 and more, and they are more complex than single toggle jaw crushers. They are provided with two toggle plates that are attached to the eccentric shaft, consequently with the movable jaw, the crushing force is increased and the capacity becomes higher.
