Raymond grinding mill feeding system and grinding system composition:

Raymond grinding mill main contain feeding system and grinding system. Raymond grinding mill automatic feeding system structure constitute: feeding roller(split rolls and quantitative rolls), material bridge and mobile feeding door and other structure. It's main function is making raw material uniform distribution along with quantitative rolls contact length and material thickness is uniform distribution on the whole length. Feeding materials through split roller appear uniform thin curtain condition falling and feeding to the grinding area. Raymond grinding mill feeding driving motor, select three-phase exchange permanent magnet low speed synchronous motors. Power is 400w, max. torque is 40Nm, synchronous speed is 60r/m(50Hz).

Feeding rolls speed testing: raymond grinding mill automatic control system, feeding rolls speed range is from 30r/min to 300 r/min, lower speed testing method can adopt measuring cycle method. Feeding rolls speed adjust good or not effect whether feeding rollers can uniform feeding or not, at the same time, determined whether raw material flow layer along the whole grinding rolls length thickness. Only when feeding roll adjust to the certain speed, we can make sure raymond grinding mill stable working, otherwise it will effect the production capacity, products quality and lead to the machine unnecessary damage. Feeding effect factors: 1. feeding roller tooth type and feeding rolls working speed; 2. feeding capacity automatic adjust function.
