How a Jaw Crusher Works: Mechanics & Applications

Introduction‌

Jaw crushers are the backbone of primary crushing in mining and aggregate industries, renowned for their rugged design and high throughput. 

A jaw crusher reduces large rocks or ore by compressing them between a fixed and a movable jaw plate. The ‌toggle plate‌ and ‌eccentric shaft‌ drive the movable jaw in an elliptical motion, crushing materials against the stationary jaw.

‌Primary Applications‌:

1.Hard rock (granite, basalt) in quarries.

2.Iron ore and copper mining.

3.Demolition waste recycling.

‌

Case Study‌: A granite quarry in South Africa increased production by 25% after replacing an outdated hammer mill with a ‌Metso C150 jaw crusher‌, achieving 1,000tph capacity.
