This setup is a 200-ton-per-hour magnesite ore-washing process plant. It is configured with a vibration feeder, trommel scrubber, vibration screen, log washer, etc. The process is as follows:

• The raw material is fed by a tipper truck or excavator into a grizzly hopper with a grizzly bear with a gap of 150 mm. Over-grizzled material larger than 150 mm is stacked nearby and under-grizzled material smaller than 150 mm enters the vibratory feeder.

• The vibratory feeder also has a grizzly bear with a clearance of 10 mm. 10-150 mm of material enters the rotary grit screen for scrubbing, while debris smaller than 10 mm flows to the settling tank for water recycling.

• This rotary scrubber‘s washing efficiency is very high. Its screening section has two layers of polyurethane with screen sizes of 4 mm and 20 mm (the 20 mm screen protects the 4 mm screen). The under-screen material (less than 4 mm) goes into the same settling tank, and the top-screen material (4-150 mm) is conveyed to the vibrating screen.

• The vibrating screen is used for further accurate screening and is divided into 3 decks of 4 mm, 50 mm, and 100 mm. The under-screened material of 4-50 mm goes to the log washer, while the intermediate sizes of 50-100 mm and the oversized material of 100-150 mm are conveyed to a separate yard.

• The log washer is used to re-wash the 4-50 mm material for a cleaner end product.
