Working Principle of Sizing Roll Crusher

2PLF series sizing roll crusher is driven by electromotor via reducer, two tooth-roller rotate inward synchronously in opposite direction. After material dropping from the inlet to crushing chamber,firstly is classified by  the tooth-roller with tooth, those which is accepted would pass through the two rollers to the discharging trough,and the massive materials would be crushed,cut, and then discharged in the discharging opening.

Structure and features of Sizing Roll Crusher
(1)  Constant-filling fluid coupling it is used as connection between the electromotor and reducer, buffering the strike and vibration generated when 
starting, as well as over load protection. 
(2) Tooth-roller
Tooth-roller is the key component of crusher, spiral arrangement of teeth. The toothholders and principal axis are assembled using the multiple dove-tail grooves, which enhance the shear strength.Small size materials are sieved out by two tooth-roller which rotate inward synchronously in opposite direction, and the massive materials are crushed by the broken tooth.Broken tooth is casted by adopting special formula which fuses multiple rare elements. 
It is  quenched after processing,make it higher strength as well as toughness,better abrasion resistanceand longer service life.
