The concentration of the beating zone is generally controlled at 15-18%, the concentration of the screening zone is controlled at 3-4%. The waste paper and the beating water enter the pre-soaking area from the hopper, and the material is mixed, and soaked in the cylinder.

Working Principle of Drum Pulper

Materials are pulped in pulping area. Due to the rotation of barrel, materials are lifted to the top of barrel and fall down the barrel bottom. After several times beating and knead between materials, waste paper are broken into pulp. 

The spraywater pipe in the screening area is used to dilute the slurry and clean the sieve hole, so that the broken slurry is smoothly and fully flowed into the pulp pool through the sieve hole, and the large heavy impurities are discharged through the slag discharge port at the back. The slurry of the slurry tank can be sent to the follow-up equipment through the pulp pump to carry out further treatment of the slurry, so as to complete the whole beating process.
