There are three kinds of refiner: single-disk grinder, double-disk refiner and DD refiner.
Single-disc refiner pulp from the feed pipe into the center of the grinding area, under the action of centrifugal force and feed pressure through the grinding area, through the grinding area of the teeth of the disk rubbing and squeezing to complete the pulping process, the working principle is that the pulp feed screw tube conveying the pulp to the grinding chamber, relying on the grinding plate grinding into a good pulp.
Double-disk refiner: the pulp from the two feed pipes into the center of the grinding area, under the action of centrifugal force and feed pressure through the grinding area, through the grinding area of the teeth of the disk rubbing and squeezing to complete the pulping process.
Double disc pulper has no requirements for raw materials in general, the basic paper raw materials are used in the pulper, unless it is pure waste paper pulping, there are individual factories will be used in place of a pressure screen pulper, if the raw material is mixed with the pulp board, it must be used in the pulper, generally out of high-grade tissue paper must also be used in the pulper.
DD Pulper is widely used in pulping of grass pulp, waste paper pulp, broadleaf wood pulp and coniferous wood pulp, equipped with manual and electric operating devices to realize manual and electric operation, or equipped with automatic control system to realize constant energy consumption control mode or constant power control of pulping, to ensure stable pulping effect.
