Mini Shale Shaker and Decanter Centrifuge for International Diamond Core Drilling

One batch of mini shale shaker and mini decanter centrifuge are ready for delivery for diamond core drilling project. It is the core equipments for the diamond core drilling solids removal unit.


A complete solids removal unit consists of shale shaker, decanter centrifuge, centrifuge feeding pump, mixing hopper, mixing pump, mud gun( agitator), compact design mud tank and accessories. The function of the solids removal unit (SRU) is a closed loop fluids treatment system to recycle the water for mineral and diamond core drilling, the purpose is to reduce the water consumption, reduce the environmental impact, improve the drilling efficiency.
According to different drilling conditions, we have 2 models of mini centrifuge for option, GNLW223 is a standard mini decanter centrifuge with max bowl speed 4500rpm and max G force up to 2492G. We can also provide variable frequency drive for this centrifuge for smaller current in start if need. GNLW224-VFD is a high configuration variable speed mini decanter centrifuge with max bowl speed 5000rpm. Both of GNLW223 and GNLW224-VFD centrifuge with bowl diameter 9 inch, the bowl length is different, the client can select it according to their actual requirement.


GNZS752 is a 2 panel mini shale shaker, to separate the coarse solids from the diamond core drilling waste water, it can greatly improve the separation efficiency of mini decanter centrifuge, and protect the centrifuge screw. Without the mini shaker, the centrifuge bowl will be blocked frequently and damage very fast. GN mini centrifuge bowl screw propeller is protected by tungsten carbide tiles for longer working life, especially when the solids content is high in the waste water, it will improve the centrifuge working life greatly.
If you need a mini shale shake and mini decanter centrifuge or complete solids removal unit for core drilling, pls contact with GN solids control.

The bottom shale shaker model is same with the shale shaker GNZS594. The treating capacity is up to 1000gpm with 2ea of 10 or 12 inch desander cone, 16 ea of 4 inch desilter cone.
Except for shale shaker, mud cleaner and screw conveyor, GN also produce drilling mud decanter centrifuge and drilling waste treatment decanter centrifuge, vertical cuttings dryer and high G drying shaker,pls contact with GN solids control.

Double Deck shale shaker and cuttings dryer for Africa drilling company

One set of double deck shale shaker and one set of vertical cuttings dryer are ready for shipment to Africa for drilling cuttings treatment system.
The double deck shale shaker will be applied as high G force drying shaker to separate the coarse solids, it can be used for both water based drilling cuttings and oil based drilling cuttings. The anti splash cover on the top to prevent the drilling mud from splashing. The top layer and bottom layer total 6pcs shaker screens are composite material frame for longer working life and better separation performance.


The vertical cuttings dryer is ideal equipment to be used for oil based drilling cuttings treatment, after treatment, the oil content on the cuttings is below 5%, the fluids will flow to an intermediate tank, then feed the fluids to decanter centrifuge for further treatment, the fine solids will be separated out by decanter centrifuge, the fluids can be reused for drilling. Before treated by decanter centrifuge, the fluids can be treated by drying shaker to reduce solids content, it will increase the decanter centrifuge treating capacity and performance, also it can prevent the centrifuge bowl from damaged by the high solids content.


GN standard drilling waste management system GNCM-40A is consist of VFD decanter centrifuge, vertical cuttings dryer, flushing pump, centrifuge feeding screw pump, fluids collection tank, skid, electric control system, accessories. The compact design with small footprint is loaded into standard container.
Except for drying shaker and vertical cuttings dryer, GN solids control also produce drilling waste treatment decanter centrifuge, including high speed decanter centrifuge, VFD decanter centrifuge, Fully Hydraulic Drive decanter centrifuge, we provide different explosion proof standard for option, IEC EX, ATEX, CNEX. For more information about high G drying shaker and vertical cuttings dryer, pls contact with GN Solids Control.

Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud
4. 1 unit of GNSB3X2C-9J centrifugal pump
5. 1 unit of GNSLH-110C jet mud mixer with mud mixing hopper and 11KW mixing pump installed on the skid
6. 1 unit of GNZYQ1000A mud gas separator
7. ATEX electric control system for the whole system
