2PLF Series Sizer Mining Equipment for Coal Crushing 

Working principle

2PLF-S series Mining Equipment for Coal Crushing is driven by electromotor(s) through reducer, toothed-rollers rotate in opposite directions,  after dropping from the inlet to crushing chamber, materials first are classified by the two rollers, those which is accepted would pass through the two rollers to the discharging trough, those agglomerate material would be crushed, cut, stretched before passing to the discharging trough. 

Structure and features

2PLF-S series Mining Equipment for Coal Crushing is composed of electromotor, torque converter, connecting cover, reducer(s), toothed rollers, and the main body.

(1)Torque converter

It is connecting the electromotor and reducer, buffering the strike and vibration generated when starting, as well as over load protection.

(2)Connecting cover

  It unites the electromotor and the reducer homocentrically , bearing weight of the motor, protecting the torque converter; Additionally, through the monitoring hole on the cover, working condition of the torque  converter could be monitored.

(3)Teeth rollers

  They are the key parts of crusher, spiral arrangement of teeth. The teeth holders are assembled with the principal axis in dove-tail slots firmly, which strengthen the cutting power.. The two rollers discharge small size material, and crush the agglomerate ones. The teeth are made of several rare elements following special metallurgic prescription processed through quench heating, possessing high intensity, toughness, abrasive resistance, and long service life.

(4)Shaft coupling

That flexible jointed by polyurethane quincunx spring coupling greatly lightens strike and vibration from the rollers to reducers.

(5) Over load protector

Speed detecting sensor over load protection guarantee safe production. The senor is connected with PLC programmed control monitoring equipment. The electromotor can be manually reversed

to remove obstruc and prevent material being blocked. Distance control can be realized through PLC programmed controller, ie. The running condition can be monitored through control room.

 This crusher eliminates over crushing phenomenon with cutting crushing technology. Small volume, light weight, suitable for 1st stage crushing, 2nd stage crushing, 3rd stage crushing in pit, workshop, and open-cut working condition.
