Multi-stage classification screen
In the OCC waste paper processing production line, the manufacturers process the long, medium, and short fibers separately according to the production process requirements. The advantages are particularly significant.
The traditional classification screen is a separate pressure screen. 进入筛顶部从顶部排出。 The pulp enters the pulp through the bottom. After screening by the sieve drum, the good pulp is short fibers. The remaining pulp does not pass through the sieve drum and continuously rises into the top of the sieve and is discharged from the top. After passing through the sand removal and entering the second-stage pressure screen, the slurry screened out is used as long fibers, and the second-stage sieve tailings need to be processed through a third-stage screen. 繁琐，消耗大，操作复杂。 The process is tedious, expensive and complicated.
Based on domestic production practices and the absorption of foreign advanced technologies, our company has developed a new generation of pulp fiber classification screens. 的三个筛选区分级处理，在实际生产中效果显著。 One classification sieve realizes the classification treatment of three screening areas of long, medium and short fibers , which has a significant effect in actual production. 段筛选区筛选后良浆作为短纤维，剩余浆料混合稀释水进入二段筛选区筛选，筛选后良浆可作为长纤维或中纤维使用。 In production, according to process requirements, long, medium, and short fiber classification can be performed. The pulp passes through the bottom to enter a section of the screening area and is screened as good fibers. The remaining pulp is mixed with diluted water and entered into the second stage of the screen. Good pulp can be used as long or medium fibers. 浆混合稀释水进入三段筛选区进行筛选。 Then, the remaining coarse pulp mixed with diluted water enters the three-stage screening area for screening. After screening, the good pulp can also be used as long fibers, and the tailings are discharged from the top.
1. Small footprint, simple operation and simplified process.
2. Low power consumption, only about 40% of the traditional process.
3. The fiber classification is clear, tailings can be discharged straight, and almost no fiber.
4. Less one-time investment.
5. Low maintenance costs.
