GN Solids Control also supplies various conveying pumps in the complete set of equipment, including screw pumps, submerged slurry pumps, sand pumps, and solid vacuum conveying pumps.

Among them, the solid vacuum pump is a new technology specially designed for conveying materials with high density, high solid content and good fluidity. Recently, GN Solids Control provided 2 sets of solid vacuum pumps to a European company. One GNSP40B is used for fixed-position transportation; one GNSP20B, this type of vacuum pump has a pulley at the bottom, which can be moved at will, and is used by customers for mobile use.

GN Solids Control vacuum pump is a pneumatic pump that uses air as its power source. It can be used to transport mine tailings, drilling waste, industrial slurry, chemical powder, construction aggregates, oil sludge, kitchen waste and other materials.

 

In solid transportation, screw conveyors are conventionally used for transportation, which has short transportation distance and high cost, which cannot be satisfied for long-distance transportation. The vacuum pump has a suction distance of 50 meters for clean water and a discharge distance of 1000 meters. It is of great significance for long-distance transportation.

The maximum processing capacity of GN vacuum pump is 40m³/h. If more processing capacity is needed, solid vacuum pumps can be used in parallel. A domestic Shanghai drilling mud company uses 4 GN Solids Control vacuum pumps in parallel, which greatly increases the processing capacity, thus satisfying On-site use requirements.

The reason why the vacuum pump can have a good effect and a longer head for solid transportation is that it can form a higher negative pressure and a positive pressure. GN Solids Control has specially designed two devices, a vacuum pump rotary discharge device and a vacuum pump buffer funnel, to relieve pressure and prevent the impact of the discharge of materials. So as to meet the customer’s requirements.

GN Solids Control mud treatment system also widely used in trenchless, piling, and shield tunneling projects. Please contact us in time if you need it.

GN Solids Control is a supplier specializing in the production of mud treatment equipment.

GN Solids Control is a manufacturer of solids control and waste disposal equipment. After more than 10 years of continuous innovation and development, GN Solids Control has become a well-known brand in the domestic solids control equipment industry.

GN Solids Control‘s continuous pursuit of equipment quality and performance is an important reason why customers at home and abroad increasingly prefer to choose GN. In August 2021, the GN solids control centrifuge was successfully used in South American drilling rigs. This time we provided centrifuges and screw pumps to customers. The specific models and introductions are as follows:

 

1. Decanter centrifuge GNLW363C-VFD

Centrifuge is widely used in drilling fluid control and barite recovery. The price of drilling fluid is very expensive, because it usually needs to add chemicals to make it have a certain specific gravity and viscosity before it can be reused, so it is very important to recover more drilling fluid. The GN centrifuge processes the drilling fluid under the action of high rotation speed and high gravity, so that the drilling fluid is separated from the solid and liquid, and more drilling fluid is recovered, and at the same time, the useless solid phase is separated, which saves a lot of cost and improves efficiency.

GN Solids Control drilling fluid centrifuges are available in a variety of sizes, including 14 inches, 18 inches and 22 inches. The decanter centrifuge GNLW363C-VFD provided this time is one of the most popular centrifuge series products, and many units have been sold at home and abroad. The conventional solids control system is equipped with two centrifuges, namely a medium-speed centrifuge and a high-speed centrifuge, while the GNLW363C-VFD centrifuge of GN Solids Control is a high-speed centrifuge with good treatment effects and good economic benefits, and is well received by customers.

2. GN screw pump GNG30-075B

GN company generally chooses screw pumps in the selection of liquid feed pumps for decanter centrifuges. Because the screw pump can control the liquid supply flow and can record the liquid supply. The flow range of the screw pump can be adjusted according to customer needs.

GN Solids Control has always been committed to providing customers with cost-effective solutions. If customers have any needs, they can contact us at any time.

GN Solids Control is a professional manufacturer of solids control and waste treatment equipment. With years of rapid development, GN Solids Control products have been sold to many countries and regions around the world. The system was successfully sold to the North American market and applied to the job site, which was well received by customers. This set of dehydration system mainly includes the following modules.

1. Receiving funnel

The receiving funnel is mainly used to collect the mud after vacuum excavation, and a metal grid is installed inside the funnel to remove larger stones and prevent larger particles from entering the vibrating screen and damaging the vibrating screen.

2. Coarse screen shaker

The slurry after removing large-size rocks through the receiving funnel enters the GN Solids Control shale shaker. The first coarse screen is carried out by selecting a smaller mesh screen to remove harmful solid phases in the slurry.

3. Double-layer shale shaker GNZS706

GNZS706 double-layer shale shaker is screened separately through the upper and lower screens. First, the slurry that has passed the coarse screen enters the upper layer of the double-layer shale shaker for a primary screening, and the liquid-phase slurry after screening falls into the second screen. The net for secondary screening can effectively remove solid phases with different particle sizes in the mud.

 

4. Desilter

The sludge remover is installed above the vibrating screen by 12 4-inch cyclones made of polyurethane material, and the slurry is pumped into the cyclone at a certain pressure through the slurry supply centrifugal pump, and the heavy solid phase and the The light liquid phase is simply separated, the heavy solid phase directly falls into the vibrating screen below for another solid-liquid separation, and the liquid phase enters the mud recovery tank from above.

5. Decanter centrifuge GNLW553-VFD

The GN Solids Control550 series centrifuge is a widely used centrifuge. Its processing capacity can meet the needs of most working conditions. The mud is discharged through the slag discharge port.

6. Chemical dosing system

The automatic dosing system can automatically and continuously add chemicals to the centrifuge to gather fine particles together, which is beneficial to the solid-liquid separation of the centrifuge and removes more harmful solid phases.

7. Mud tank

According to the actual processing capacity of the customer on site, our company matched the corresponding mud tank for the customer. The main tank size is 10369x2100x2312mm, and it is equipped with protective equipment such as pipe manifolds and protective fence walkways.
