Beating Principle of Drum Pulper


Drum pulper developed by Zhengzhou Leizhan works in a consistency of 18%-22% and makes soft rub in waste paper, by doing this, paper fibers are fully dampened and separated, and save the strength and length of waste paper to the greatest extent.

Beating 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.
