HYDRAPULPER


HydrapulperWhen the bales of woodpulp or waste paper arrive at the papermill they are loaded onto a conveyor and passed into a circular tank containing water. This has a very powerful agitator at the bottom which breaks up the bales into small pieces.

The pulp mass created begins to look like thick porridge. This machine is known as a Hydrapulper. It operates automatically and when the disintegrating process is complete it discharges the pulp into large storage tanks.

Hydrapulpers used mainly for handling waste paper are fitted with special devices for removing unwanted contraries such as wire, plastic, paper clips, staples etc.
