D Series Decanter Centrifuge

D Series Decanter Centrifuge is used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.

Application:

D Series Decanter Centrifuge is used in separating suspension of solids phase with particle ≥2μm in diameter for drilling mud and fluids handling.
It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas.
This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management.
It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G.

Working Principle:

Decanter Centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed.

D Series Decanter Centrifuge Features and Benefits:

1. Innovative design includes longer bowl, allowing drilling fluids to thread through more slowly, thus resulting in drier solids and finer separation point;
2. Big bowl offers big volume. It also generates high-G force;
3. Stainless steel bowl, scroll, compartment are available and covered with corrosion-proof coating so as to have longer lifespan;
4. Tungsten carbide scroll points with wide spacing flights at tapered end create a finer layer of conveyed solids for consistent, uniform separation and maximum solids control efficiency.
5. German FAG or Swedish SKF brand bearings are available;
6. Electrical Components complies with SIEMENS/Schneider ATEX or IEC Ex.
7. Screw pump and submersible slurry pump are provided to meet liquid feeding requirements of centrifuge of various customers
