Washers are used for washing contaminated and clotted material. Depending on the application, different types of washers are used.
In a log washer, the contaminated grain is fed in at the lower end of the trough and transported upward in a zigzag manner by the paddled longitudinal shafts. The resulting friction of the individual stones causes the impurities to be pulverised, dissolved in the water and run off.
Drum washing machine
In a drum washing machine, the motorised wheels rotate the drum. Conveyor blades are mounted inside the drum, which move the material forward. An intensive friction wash inside the material is enhanced by built-in lifting bars. The dirt particles and fine particles as well as organic materials such as wood in the gravel mixture are washed out according to the counter-current principle.
Similar to the drum washing machine, the bulk material is passed through a water bath in the turbo washer. The cleaning effect of the turbo washer is enhanced by a combination of friction and pressure, which is created through the wedging of the material between the rotor and the trough.
