Double Toggle Rock Jaw Crusher

Double Toggle Rock Jaw Crusher

Product Introduction  

Small jaw crusher, small rock crusher is widely used to crush various large stones, limestone, granite, basalt, river gravel, etc. Jaw crusher`s highest anti-pressure strength of material to be crushed is 320MPa. The jaw crusher is mainly used to crush hard and medium hard stones in stone mining, metallurgy industry, building material, highway, railway, chemical industry, etc.

Features of Jaw Crusher        

• 1. Symmetrical deep crushing chamber is adopted to maximize the range of feed size, capacity and crushing ratio.
• 2. Three-dimensional software is adopted to optimize crusher parameters and reduce equipment self-weight, so capacity is increased by more than 30%.
• 3. Bearing seat is designed integrally, so manufacturing difficulty is greatly reduced, and bearing life is increased.
• 4. There is a thick replaceable plate on the top of moving jaw to prevent moving jaw from being impacted.

Working Princle: The motor transmits through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when mobile jaw moving. So the mobile jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
