High Quality Drum Pulper-Paper Pulping Machine


Drum pulper effectivcely pulps recycled waste paper. Drum pulper consists of pre-soaking area, pulping area and screening area. Advantages of drum pulper are: Avoid cutting action of traditional pulper, increasing physical index of paper, less energy consumption, reduce maintenance cost, etc.

Pulping Principle of Drum Pulper

The concentration of beating area is 15-18% and concentration of screening area is 3-4%. Waste paper and beating use water enter pre-soaking area through feed hopper and all materials are mixed, soaked.
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 function of water spray pipe of screening area is to dilute slurry and clean sieve hole. So, pulp can pass sieve hole and flow into pulp chest smoothly and fully and large light, heavy impurities expel from slag discharge outlet.
Pulp in pulp chest are transported to following equipment by pulp pump for further treatment to finish the complete beating process.
