stone crushing production line,roll crusher for crushing stone

Introduction

Quad roller crusher suitable for the solid material that compressive resistance strength is less than 300Mpa,humidity less than 30% to proceed fine crushing. Such as coal, coke,  ceramics raw materials,mine,grain slag,Gypsum,clay,salt,chemicals and other solid materials.

Features: low use and maintenance costs,high ratio of reduction, high reliability, low dust , low noise.

The four rollers of quad toothed roller crusher are divided into overlay welding rollers or flat rollers,

according to the discharge size requirement to combination, It is suitable for the materials(feed size

is less than 90mm,discharge size required 0.2mm-10mm) to proceed  fine crushing.Such as steel

industry crushing coke;Quartz industry crushing quartz stone;Iron industry crushing iron ore;or in the

 similar occasion as above.

Working Principle
Four roller crusher is fixed with four high-strength wear-resistant alloy grinding rollers. Their relative rotation makes high extrusion pressure and shear force for crushing the material.

Firstly the material is fed into the space between the top two rollers. Through the rotation of the top two rollers, it is extruded, rolled and sheared (rough broken) .

Then, it is secondly extruded and gnawingly milled (fine crushing) by the middle two rollers which are relatively rotating.

Finally, under the extrusion, cut and mill of the next two rollers, the material becomes the required size, sent by the transport equipment.  

 Packing:   Export standard package, usually in bulk or wood case as per different requirements.
