Cast Iron Grinder 450 Double Disc Refiner for Pulping Line

T1. Disc refiner is made of niobium alloy cast iron; the main material is cast iron.
2. The equipment is mainly used for coarse beating, refining and re-pulping of broke and waste paper.
3. It is available for long fiber pulp such as cotton, wood and hemp.
4. The equipment is furnished with automatic control system and can beat with constant power or constant energy consumption.
5. The beating effect is stable.ume.
The double disc refiner consists of a refining chamber, a transmission mechanism, a base, and a motor. The refining chamber consists of two fixed grinding discs fixed on the casing and the moving seat and two rotating grinding discs installed on the rotating disc to form two grinding areas. Through the exchange of different tooth-shaped grinding discs, to meet the pulping requirements of various pulps.
1.The double disc refiner consists of two fixed grinding discs fixed on the casing and the movable seat and the grinding discs installed on the rotating shaft to form two grinding areas.
2.The pulp enters the center of the grinding area from two pulp inlet pipes, passes through the grinding area under the action of centrifugal force and pulp inlet pressure, and completes the pulping process through the squeezing and impact of the toothed disk in the grinding area, and is sent out from the pulp outlet.
3.The rotating disc and the main shaft are connected by spline, which can make flexible axial movement.
4.The adjustment of the grinding disc gap is manual adjustment. The screw nut is driven to rotate by the transmission of the worm and worm wheel, so that the screw rod pushes the stator blade into the corresponding axial movement, so that the gap between the two grinding areas is changed, so that the gap and pressure of the grinding disc reach process requirements, the size of the current is an indication of the pressure in the grinding area.
5.The elastic cylindrical pin coupling is adopted, and the operation is stable.
6.Grinding disc material is wear-resistant alloy cast iron, which has been completely grind and processed.
