4PG CRUSHER

Introduction

Four teethed roller crusher is suitable for compression strength less than 240Mpa,water content less than 30%of the medium hard and soft materials.In addition,it is suitable for fine and intermediate crushing which has few powder and lots of grains.Such as coal,coke,fertilizer,raw material,petroleum coke,glass, chemicals and other solid materials.It has the characteristics of low maintenance cost,large crushing ratio, reliable performance,less dust and low noise.

The four teethed roller crusher is equipped with four crushing rolls,the upper two rolls are the tooth roll faces,and the lower two rolls are the stacking roll faces (flat roll face or straight tooth optional),suitable for feeding  particle  size  less  than  700mm,finished  product  size  requirements  2-30mm  medium  and  fine crushing operation.Such as electric heating plant fluidized bed boiler,ordinary boiler broken coal,chemical fertilizer  plant  broken  fertilizer  raw  materials;copper  industry  broken  frozen  ore  powder;solar  industry broken waste glass tube;or similar to the above crushing occasions.

Working Principle

Four rollers crusher is fixed with four high-strength wear-resistant alloy grinding rollers.Their relatively rotation  makes  high  extrusion  pressure  and  shear  force  to  crush the  materials.Firstly  the  material  is entered  into  the  space  between  the  top  two  rollers.It  is  extruded,rolled  and  sheared  (rough  broken) because  of the  rotation  of  the  top  two  rollers.Then,it  is  secondly  extruded  and  gnawing  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,then be sent out by the transport equipment.
