Recently one set of big bowl decanter centrifuge package is ready for delivery to international mining tailings dewatering project. The big bowl decanter centrifuge model is GNLW764A-VFD, which has been widely used for mining tailings dewatering project in the past. The system including 2 containers, the top container with big bowl decanter centrifuge, the bottom container with chemical dosing unit, both of the containers with windows and doors, for convenient transportation and operation.
GNLW764A-VFD decanter centrifuge technical parameter is as below:
Bowl diameter is 30inch (760mm), bowl length is 3328mm, the max capacity is 120m3/h, the treating capacity for oil sludge , mining tailings and other materials will be various as per different conditions. max bowl speed is 2650rpm, max G force is 3000G, the mechanical separation cut point is 2~ 5 microns, differential speed is 5~ 28 rpm, and gearbox torch is up to 25000 N.M., gearbox ratio is 38:1, the main motor is 160KW (217HP)，back drive motor is 90KW (120HP). The bowl main components including big end, small end, are made of duplex stainless steel 2304, the collection box is also made of SS304, the screw is made of stainless steel, and the bearing is from SKF for reliable working. By working with chemical additives, the centrifuge can separate ultra fine solids from the mining tailings, to get more clear water and drier solids. VFD control panel for main motor, back drive motor and feeding pump motor can adjust the motor frequency and control the feeding rate and get required treatment result.
The coal dewatering centrifuge can be utilized for coarse coal, fine coal, ultra fine coal, coal tailings dewatering treatment. Compared with filter press, the dewatering centrifuge is with small footprint, easy operation and maintenance, less cost, less maintenance cost. For more information, pls contact with GN solids.
