Log Washer
A heavy-duty log washer developed for cleaning ores with a high clay and mud content, providing effective washing and separation with its counter-rotating twin-shaft design.
Product description
Log Washer
Powerful and Effective Washing for High-Clay Ores
A log washer is a heavy-duty industrial washing machine used to clean ores containing high levels of clay, silt, mud and sticky foreign matter.
Its counter-rotating twin shafts and abrasion-resistant paddles break up the clay layers on the material and clean the ore effectively. It is the preferred choice for high-efficiency washing, particularly in mining, aggregate production and mineral preparation plants.
KRIOS Engineering designs its log washer solutions according to the plant capacity, the properties of the material to be processed and the project requirements, providing solutions suited to each production process.
Working Principle
Material fed into the washing tub is continuously agitated by specially designed paddles on two shafts rotating in opposite directions. During this movement, the clay and mud layers on the material are separated by mechanical attrition and the action of the water.
While the washed material is carried to the discharge section, the separated fine particles and the dirty water are removed from the system.
