1. the materials enter into rotary drum from the feeding hopper in which they tumble and rub each other with the rotation of the drum. The clean spraying water and bubble waving make dirt and sand on the surface of the materials fall off and discharged from the drum sieve holes together with the drained waste water. There are brushes at intervals in the drum so that the raw materials will get further cleaning under the action of pressure difference and brush friction. Finally, the material after washing will be further cleaned by high-pressure water spraying.
