Versatile and efficient.


With a very similar design and operation to a concrete mixer’s drum.

The cleaning spiral screw is welded inside the drum, which turns as the drum rotates. The cement and water particles are separated from all other waste materials when they are shifted and come into contact with water.

There are a series of enclosures on the last section of the spiral, which shift the washed aggregates up and deposit them on the outlet tray.

The unit features a vibrating outlet tray that helps recover the aggregate, using less water than other systems (it is placed at the drum discharge position and it is inserted into its body)
