The double disc refiner is a continuous beating equipment for the paper pulping system. It has the characteristics of compact structure, small footprint, high efficiency, low power consumption, strong adaptability, simple operation, flexible adjustment, and convenient maintenance. It is the ideal continuous Beating equipment. According to the requirements of the beating process, single or multiple units can be used in series or parallel.
Advantage:
(1) Mainly used for beating pulp to improve the tapping degree of pulp and meet the needs of papermaking.
(2) A variety of tooth-shaped grinding discs can be installed, with a wide range of raw materials, suitable for wood pulp, chemical pulp, chemical pulp, waste paper pulp, etc.
(3) Double grinding zone, high refining efficiency.
(4) High versatility and convenient maintenance
1. Improve the beating degree and wet weigh of pulp.
2.The equipment is furnished with automatic control system and can beat with constant power or constant energy consumption.
3.The rotary disc and the main shaft are splined to ensure the pressure balance in the two grinding areas.
4.The beating effect is stable and uniform.

This refiner is made up of main body, coupling and feed gear, etc.
The refiner has two abrasive sections. By the inclination angle of abrasion pattern, four abrasive plates are fixed, two left and two right. Two left plates are fixed on inner wall of machine shell and inside of rotating disc and two right plates are fixed on outside of rotating disc and moving pedestal, forming two abrasive sections (see drawing for installation instruction). Stock is conveyed to abrasive section through inlet pipe. After beating and refining, pumped out from the abrasive section and flows into shell, at last discharged from outlet pipe.
There are two bearings on the main shaft and fixed by bearing pedestal and connected to motor via coupling by Nylon column pins. The turntable is on the other side of the main shaft. And there are abrasive discs on each end of the turntable, and the turntable rotates between two abrasive discs and axially moves under pressure.
Movable pedestal is adjusted by feed gear with axial movement to adjust the space between two abrasive sections. A feather key is set between movable pedestal and machine case and pushed by trapezoidal screw.
The cover is a welded structure which is connected with the case by pin roll. Withdraw the whole movable pedestal into the cover and loosen the locking bolts before opening the cover. Keep the surface clean and withdraw the movable pedestal into the cover before closing the cover. Then fix uniformly fasten bolts.
2.CouplingCoupling is connected by Nylon column pin with the character of easy dismounting and maintenance. It meets the requirement of displacement of feeding and relieving and transmit torque
3.Feed gearFeed gear covers worm gear reduction system. Under force of worm gear, trapezoidal thread screw rotates and drive the movable pedestal forward or backward. The movable pedestal moves 0.23mm for each circle of motor. When rotating clockwise, it moves forward while anticlockwise backward.
