High capacity small concrete stone rock crusher price for sale

Introduction
Jaw Crusher is ideally suitable for primary and secondary crushing. The highest anti-pressure strength of crushed material is 350MPa.      construction equipment 

It is widely used in mining, metallurgy, construction, highway, railroad, and chemistry industries and etc. Many models are available according to your different fineness requirements.

In the ore dressing process, jaw crusher is the key role in the beginning of ore crushing stages, it is the key equipment of coarse crushing and find crushing before ore grinding.

Structure
Jaw crusher machie  made up of frame, eccentric shaft, grooved wheel, flywheel, moving jaw, side guard plate, toggle plate, toggle backseat, adjusting screw, returning spring, fixed jaw plate and moving jaw plate. Toggle plate is of safety function.

Working principle
The motor drives pulley of jaw crusher, making the movable jaw do periodic movement through eccentric shaft. The angle between toggle plate and movable jaw increases when movable jaw moves up. So the movable jaw moves to the fixed jaw. The stones are crushed in this process in jaw crusher. The angle between toggle plate and movable jaw decreases when movable jaw moves down, the movable jaw moves away from fixed jaw by the pulling of rod and spring, the crushed stones are discharged from the outlet.

Our Advantages

Deep cavity crushing, energy saving
Optimized deep cavity crushing, no dead zone, greatly improved feed and crushing efficiency, single machine energy saving 15% -30%, system energy saving more than double.

Centralized lubrication system, easy maintenance
The uniquely designed centralized lubrication system makes component lubrication faster and requires less maintenance.

Strong carrying capacity and high stability
The larger forging blank processing heavy-duty eccentric shaft, high-manganese steel plate and high-alloy cast steel assembly, the equipment bearing capacity is stronger and the stability is higher.

Advanced technology and long service life
