My collegue just shared another great news, after sent 10 sets of decanter centrifuge to Africa, plus another big order with more than 40 sets decanter centrifuges, now in Africa we have far more than 100 decanter centrifuges. 
You must wanna know what is happening. Top quality product, best service, and public praise.
Except more than 30 years experance engineer teem, we also hired another team lead by engineer who deal with Alfa Laval decanter centrifuge for moren than 20 years, went to many sites, different applications. We get more updated features from GNLW363B, to GNLW363C, after collecting all the feedbacks from different sites. A more robust products finally come to the world, while we still keep improving at the same time.

Normally when a client trying to find a proper decanter centrifuge, they may consider:
1. Material
2. Screw protection
3. Failure protection
Freely to let us know if you are interested in details of GN Decanter Centrifuge.

The fixed speed centrifuge & variable speed centrifuge is good combination for barite recovery and mud weight cutting. Fixed speed centrifuge is mainly working for mud weight cutting; the variable speed centrifuge is mainly working for barite recovery, most working under 2200rpm to 2700rpm. When the job only need one function like mud weight cutting, the two centrifuge can working together at similar speed. During the actual job process, the user need to continuously test the feeding mud, discharge mud and continuously adjust the bowl speed of centrifuge to get proper treating results.
In the recent orders, client normally purchase different centrifgues with fixed speed and VFD. For more flexible applicating on site.
