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.

Screw Conveyor and Solids Control Equipment for Middle East Drilling Company

One batch of screw conveyor and solids control equipments are ready for shipment to Middle East Drilling Company. The equipments list including screw conveyor, shale shaker and mud cleaner as below:

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.
