Jaw crusher

Jaw crusher introduction 

Jaw crusher is one of the most popular stone crushing machines used in mining industry and it is ideally suitable for both primary and secondary crushing. PEW series single toggle jaw crusher has the features of great crushing ratio and uniform sizes. It can be used to crush materials with compressive resistance less than 320 MPA. It is widely used in various industries, such as mining, smelting, road and railway construction, chemical industry, etc. PEW series jaw crusher is used for primary crushing and secondary crushing.The maximum compression strength of materials to be crushed is 320MPA. Our design and production are of high position both at home and abroad.

 

Jaw crusher has advantages of simple structure, reliable work, easy to maintain, low cost of production and maintaining. It’s widely used for crushing materials which the compressive strength does not overtake 320MPa in mine metallurgy, building materials, chemical industry and other industries.

 

The work method of Jaw Crusher is as follow.

The motor drives the mobile jaw up and down through eccentric shaft. The angle between toggle plate and mobile jaw increases when mobile jaw plate moves up. So the mobile jaw plate closes up the fixed jaw plate. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when mobile jaw moves down. The mobile jaw plate move away from the stationary jaw plate with the pull of draw rod and spring, so the crushed stone will be discharged from the outlet. This process will repeat. The moving jaw will crush and discharge the stuff circularly.

Please carefully examine the fasteners, especially the lubrication components and bolts before starting the machine. Enough oil is needed on each lubrication component. Fasten the loose bolts, clean the crushing cavity, and then start the machine. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.

 

Feature:

-The deep crushing cavity increases the feeding capacity and output capacity;

-High ratio of crushing, homogeneous final product size;

-Adjusting the discharge opening through gasket, more convenient, it can meet different customers’ requirenment

-Lubricate system is safe and reliable, easy to change the spare parts;

-Simple structure, easy maintenance, consumption cost is lower;

-Energy-saving, for one set saving about 15%-30%;

-Little noise and dust.

 

Application of jaw crusher 

 

Jaw crusher is mainly used in metallurgy, mining, chemical, cement, construction, refractories and ceramics in the industrial sector for a variety of pieces and crushing of hard ores and rocks with.
