High Density Cleaner

Grubbens High Density Cleaner takes care of unwanted particles and removes them from the suspension using the vortex separation principle. Parts that have a higher density than the pulp, such as screws, nails, staples, steel parts, stones and pebbles are effectively removed and gathered in the reject chamber.


When installed in your existing plant the cleaner comes with separate rotor, which allows it to operate without any pressure drop. When the cleaner is installed in a new system the capacity of the pump will determine the pressure in the cleaner.
