This week GN solids control shipped 2 units of Large Bowl 30 inch GNLW764A Decanter Centrifuge for Mining Industry to Australia, this is the largest centrifuge model we have made right now, we have 9 inch, 14 inch, 18 inch, 22 inch and 30 inch bowl decanter centrifuge with different treating capacity, different speed, different G force for various applications.
The diameter of the centrifuge bowl is 760mm, the bowl length is 3328mm, the treating capacity is 528gpm, max bowl speed is 2650rpm, typical bowl speed is 2200rpm, max G force up to 3000G, typical G force is 2060G. The main power is 160KW, back drive motor is 90KW, the gearbox Torch is 25000.N.M.
Same with the smaller decanter centrifuge, the screw propeller protection is tungsten carbide tiles, the bowl fluids distribution port and solids discharge port is protected tungsten alloy for longer working life, the bowl material is made of duplex stainless steel 2304 for anti corrosion.
The bearing for this big bowl centrifuge is very big, need separate lubrication system for better lubrication to extend the working life of the bearings. The plate type heating exchanging system can effectively cool down the lubrication oil so that to get a better cooling performance and the temperature sensor installed on the bearing seat will send signal to the PLC to trip off the centrifuge in case of over high temperature.
The bigger size of the centrifuge bow, the higher speed of the centrifuge rotation speed, the higher technology is required to produce the centrifuge. As the top decanter centrifuge manufacturer in China, GN solids control have the capability to produce big diameter bowl centrifuge, high speed decanter centrifuge, VFD variable speed decanter centrifuge, FHD full hydraulic drive decanter centrifuge to meet the requirement of our international clients from different applications.
