(Free-Press-Release.com) February 21, 2012 -- How a jaw crusher works and what jaw crusher is used for

Jaw crusher can be of different sizes of raw materials, broken into particles of uniform small pieces, jaw crusher (broken jaw) in industrial and mining enterprises, this is because the aircraft structurerelatively simple, the model is complete and has a large. The jaw crusher (broken jaw) as a (coarse broken and in pieces) broken machinery use. Jaw crusher either and mineral processing equipment, gravel equipment for, but also can be used alone. The jaw crusher to produce the cornerstone of the road, railway ballast stone and construction sand and gravel aggregate. Existing jaw crusher (jaw crusher) pressing the jaw movement characteristics, and divided into simple swing jaw crusher, complex swing jaw crusher and three forms of mixed swing jaw crusher.

The jaw crusher is the use of the two jaw plate material extrusion and bending role rough broken or broken in a variety of hardness materials broken machinery. The broken bodies of the fixed jaw plate and movable jaw plate, when the two jaw plate close to the material is broken when two jaw plates leave the material is less than the discharge opening at the bottom of the discharge. The crushing action is carried out intermittently. This crusher due to the advantages of simple structure, reliable and hard materials can be broken and is widely used in mineral processing, construction materials, silicate ceramics and other industrial sectors.
The 1980s to twenty per hour crushing about 800 tons of material a large jaw crusher feed size reached 1800 mm. Common jaw crusher the elbows board and two of the single-bracket. Former moving jaw at work only to make a simple arc swing, it is also known as a simple swing jaw crusher; latter arc swing up and down movement, it is also known as complex swing jaw crusher.

In addition, in order to meet the nesting size requirements and compensate for wear of the jaw plate, additional nesting population adjustment device, usually put in between the bracket seat and rear rack adjust shim or wedge. However, in order to avoid affecting production, the replacement of broken parts and hydraulics can be used to achieve insurance and adjustments. Some jaw crusher with hydraulic transmission to drive the movable jaw plate, in order to complete the crushing action of the materials. These two types of jaw crusher with hydraulic gear, often referred to as the hydraulic jaw crusher.
The jaw crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and chemical industry and other various materials crushing compression strength not more than 320 MPa. The jaw crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and chemical industry and other various materials crushing compression strength not more than 320 MPa.
How to solve problems in the operation of the jaw crusher?
1) to replace or increase the crusher;

2) The exchange of electrical wiring;
3) the discharge opening adjusted to the instructions provided for the nominal discharge opening and increased crusher used for crushing; jaw crusher picture;
4) Check tooth plate pitch dimensions, such as sub-standard shall be to replace the jaw alignment relative position of the fixed jaw plate and the activities of jaw, to ensure the addendum on the tooth root, fixed clamping to prevent shifting;
5) to increase the voltage of the workplace to adapt to host overload requirements;

6) the replacement of bearings or moving the jaw. The activities of the fixed jaw jaw broken, why have beat or percussion?
Remedy:
1) to replace the tension spring;
2) the replacement of the rod;
3> re-install or replace the bracket. The jaw crusher host suddenly stop (commonly known as: boring cars) Remedy:
1) removal of the obstruction in the discharge opening, to ensure the smooth flow of the material;
2) tighten or replace V-belt;
3) re-install or replace the adapter sleeve; 4) align the workplace voltage to make it comply with the requirements of the host operating voltage; 5) Replace the bearing.
