Comparing with other solids control equipment like the shale shaker, desander, desilter and other equipment, the decanter centrifuge clearly need more attention and more care during operation in order to make sure a good performance, especially on the 24*7 running jobsites.
As the leading manufacturer of solids control and waste management manufacturer in China, GN has been producing hundreds of decanter centrifuges and GN centrifuges are working all over the world, GN has following tips to share with the decanter centrifuge owners or operators.

a good choice of centrifuge

GN decanter centrifuge

1. Before confirming the model, collect as much as information including the those points: the jobsite condition, like the temperature, the end users’ special request like the EX standard (ExdIIBT4? IEC EX? ATEX or Gost?), the allowable max electric current, and electric specification of the jobsite(380V, 50HZ? 460V, 60HZ? 415V, 50HZ or others?). And try to collect as much information of the material to be treated, the largest particle size, the solids contents before treatment, and the allowable largest particle size and solids content after treatment. A right choice of decanter centrifuge is the precondition of its good performance. Those are GN Centrifuge Models for your reference.
2. Before installing and commissioning of the decanter centrifuge, read the user’s manual carefully and get a general idea of the specific model of decanter centrifuge and the control panel. Normally, the VFD controlled decanter centrifuge is more complicated to operate, the operator need to have both mechanical and electric knowledge to handle it, at least for operate it.
3. Assign a specific professional engineer or operator for each decanter centrifuge. His work is to observe the condition of the decanter centrifuge and discover any problem at the first time and solve it. Because the centrifuge is high speed running machine, and when the mud condition changed a bit, it affect the performance and the centrifuge service life.
4. Lubricate the centrifuge on time, especially the bearings. Like GNLW363CG decanter centrifuge, the bearings are original SKF bearing. Good bearings ensure a longer service life on basic that you maintenance them carefully. Per manual’s instruction, some points of decanter centrifuge need to be lubricated every shaft and some need to be lubricated after running some hours.
5. A standard equipment is designed for common conditions, but not for all. In some cases, the end user need to make the jobsite condition to suit the equipment, like to make some isolation for keeping the equipment warm or cool, sometimes, the end users even put the decanter centrifuge in a air conditioned room or container to get an ideal performance.

In the past CIPPE 2016, GN Solids Control brought its centrifuge family to the show, all the centrifuges from the 9 inch baby centrifuge to the 22 inch big brother centrifuge, standing in a row and visited by many visitors and end users.

Especially the GNLW363 Decanter centrifuge, both the old look one and the new design were shown in CIPPE 2016, and the new one was positioned on a skid. What’s the differences between each generations GNLW363’s?

1, first generation GNLW363, the original design for 14 inch decanter centrifuge, with the two motors on each side of the centrifuge. although the material used is better than others, the centrifuge is still an old looking one.

2, second generation GNLW363B, it is more international looking, as GN Solids Control has been selling its products to many countries and regions in the world, and GN’s products design became more and more international, GNLW363B decanter centrifuge’s motors are located on same side of the centrifuge, it allowed the operators to have more space for operation.

  1. third generation GNLW363C decanter centrifuge, for outlook, it is similar to GNLW363B, with two motors on one side. But there are more small but useful changes on GNLW363C, because the centrifuge was used for many applications since then, like the oily sludge separation, the dewatering unit and etc, with feedback from jobsites, GN re-designed it and better it a lot.

4, forth generation GNLW363D, the inside design is similar with GNLW363C, but the outlook is quite different, as the structure is more compact and total weight is less, easy for air shipment in case of urgent use.

For the same model of GNLW363D/C decanter centrifuges, GN has optional control panels like fixed speed control panel, VFD control panel of normal one, and the positive pressurized control panel with PLC smart touching screen.
