The drum type ore washing machine equipment is commonly used for various difficult to wash block iron ores. The drum type ore washing machine is divided into two types: round drum type and round drum plus screening strip type. The drum type ore washing machine can divide the washed raw materials into+40mm and -40mm secondary commodities, and the -40mm inner double spiral structure tank type sand washing machine can further clean the raw materials into+2mm and -2mm secondary commodities. The ore washing efficiency can reach up to 98%, which is the most effective method for difficult to wash iron ore.
The cylinder section of a large cylindrical ore washing machine is composed of a pulping section and a screening section, and the cylinder body is made of wear-resistant rubber as a jaw.
The basic principle of a large drum washing machine: the cleaning drum section is supported by four towing wheels, the electric motor drives the reducer, and the size transmission gear drives the cleaning drum section to rotate at low speed. Iron ore with mud and lime powder is fed from the feeding port and enters the rotating drum. It is cleaned by installing a wear-resistant rubber lining plate with a certain angle of view inside the drum, which continuously drives the throwing down. The entire process is moved several times from the feeding end to the feeding end, and the system is washed and rinsed in both directions or reverse directions. The clean iron ore is lifted by the drum washer and unloaded into two layers of conical screens, which are divided into coarse, medium, and coarse The three fine particle size distributions are discharged respectively. Sewage with sludge is discharged according to the perforated partition at the feeding or feeding end.
