 Description of Jaw crusher

Jaw crusher is not only able to be usedtogether with mine-selecting and gravel processing equipments but also be usedindependently. The Jaw crusher is used for Primary crushers and Secondarycrushers for crushing all kinds of minerals and rocks with compressive strengthless than 320 mpa. There are two types of Jaw crusher: coarse jaw crusher andfine jaw crusher. We Henan Hongxing Machinery also manufacture Mobile jawcrusher, Single toggle jaw crusher and other Jaw breakers.

Working principle of Jaw crusher

 The strip and strip pulley are driven by amotor, and the moving jaw moves up and down via eccentric shaft. The anglebetween fixed jaw and moving jaw becomes smaller when the moving jaw runs down,then the materials are crushed into pieces. It will become bigger when themoving jaw runs up. The moving jaw board leaves the fixed jaw board under theaction of pole and spring, and then the end products come out from the crushingcavity. And also, Jaw crusher is always used as the Primary jaw crusher.

Jaw crusher's Performance and Features

1. Crushing cavity is deep and there is nodead area, which improves feeding capacity and output;

 2. High reduction ratio and uniform finalproduct size;

 3. Spacing piece type discharge-holeadjustment device is reliable and convenient;

 4. Reliable and safe lubrication system,convenient replacement of parts and small work load of maintenance;

 5. Simple structure, operational reliabilityand low operation cost;

 6. Energy-saving: single machine can saveenergy by 15% to 30%; the system can save energy by over 30% to 60%;

 7. Large adjustment range of discharge holecan meet the demands of different users;

 8. Low noise and little dust; 

 9. Simple structure; convenient maintenanceand use; stable performance; low operation cost; high reduction ratio.

10. The outlet employs pad-styleadjustment devices, convenient and reliable, and increases the flexibility ofthe equipment.
