Decanter Centrifuge and Cuttings Dryer for Domestic Client

January 07 2019

Comparing with the traditional drilling mud recycling system that will dig a mud pit on the ground, the closed loop mud

recycling system is being more and more preferred as the environmental protection regulations issued are much stricter than

ever before. This is why the decanter centrifuge and cuttings dryer unit would be used to recover more drilling fluids from

the discharged cuttings.

The decanter centrifuge and cuttings dryer here mentioned in this article are equipped for a 1500HP oil rig for a domestic

client. It is well known, GN is the first one API certified manufacturer in China whose both the decanter centrifuge and

cuttings dryer are proved perform well on site. GN’s drilling waste management system is designed basically on

consideration the function of the decanter centrifuge and cuttings dryer.

The drilling mud recycling system for a 1500HP rig will need a large volume of drilling mud to keep the rig working

continuously. Of course, the drilling cutting discharged from the primary shale shaker is also a large volume. By using GN

’s cuttings dryer, the oil content on the cuttings could be reduced down to less than 5 percent. After further separation

by the cuttings dryer, more valuable drilling fluids could be recovered. And then immediately, the effluence out from the

cuttings dryer would be transferred to the high speed decanter centrifuge for polishing. By using the cuttings dryer and

decanter centrifuge unit, the waste discharges could be greatly reduced and the more fluids could recovered for reuse. This

is good for environment protection and cost saving on the operation.

In recent year, GN is keeping perfecting the design of decanter centrifuge and cuttings dryer unit. From all aspects, the

performance of GN’s equipment is significantly improved. Not only in domestic market, but also the customers from abroad

come to GN for business cooperation, and a great number of the customer is for repeated orders as GN’s decanter centrifuge

and cuttings dryer really work satisfactorily.

GN Decanter Centrifuge for Chemical and Mining Industry

January 01 2019

GN Solids Control has expanded the decanter centrifuge application to chemical and mining industry. With many years of experience of our centrifuge engineers, GN can offer cost-effective solutions for the chemical and mining industry.

Following is the our main applications:

1) Chemical and Pharmaceutical Decanter Centrifuge

GN centrifuge for chemical industry is to do Solids and liquid separation of chemical fluids, and clarify the liquid for different gravity. More over GN centrifuge is able to do Solids mixture classification, and dehydration of liquid solid mixture.

2) Ore and Mineral Separation Equipment

Many different Ore processing like gold and silver, Lanthanoids, lead and zinc, nickel and copper, platinum are suitable to be processed with GN separation equipment. GN shale shaker, hydrocyclones and decanter centrifuge are widely used in the mining industry for separation of minerals, raw materials and ores.

Other Application

Grinding and Polishing Liquid

Plastic Recycling

Soda Plant Waste

Pulp & Paper Waste

The reason why GN Solids Control can make the start-of-art centrifuges for the chemical industry is because of two main reasons. One is that, we have the talent and experienced centrifuge engineers with over 20 years’ experience, the other reason is that we have the advanced CNC machineries with strict QA and QC for the production according to API and ISO regulations.

Decanter Centrifuge

centrifuge solids control, dewatering

GN Decanter Centrifuge is designed for the drilling mud solids control and oilfield waste management.GN VFD drive decanter

centrifuge with variable speed allows drilling contracor or mud service company to do the barite recovery, fine/ ultra fine

solids separation,dewatering centrifuge.GN have the decanter centrifuge from 9 inch bowl to 22 inch bowl available for

different applications.GN decanter centrifuge bowl length and diameter ration is over 3, this gives the best result for the

drilling fluids cleaning.

Large Bowl 30 inch GNLW764A Decanter Centrifuge for Mining Industry to Australia

Dec 20 2018

This week, GN arranged the shipment of two sets large bowl decanter centrifuge to Australia for coal mining slurry dewatering process.

The model of the large bowl decanter centrifuge is GNLW764 that is the largest centrifuge GN can make at this time. For the coal slurry dewatering project, always a large flow capacity is required. That is why the client selected GN largest decanter centrifuge.

Features of GN Large Bowl Decanter Centrifuge GNLW764A

1. The rotating bowl is made from duplex stainless steel 2304 with centrifugal casting processing for better balance performance.

2. Screw conveyor is also rom stainless steel and the blade is protected with tungsten carbide for long working life.

3. To protect the motor of the large bowl decanter centrifuge. GN equips the VFD control panel for the operation of the centrifuge. So that the motor can be started to run at a low speed to prevent the over high electric current to burn the motor. In the meanwhile, a VFD control panel will let the operator to run the decanter centrifuge with different speed for various process purposes.

4. The lubrication system is using oil pump to feed lubricants to both of the bearing seats. 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.

GN decanter centrifuge is mostly used in drilling mud solids control. However, now is applied in more and more other industries like mining slurry dewatering, waste water treatment and oily sludge treatment. For more information on GN big bowl decanter centrifuge, please contact us freely.
