GN solids control shipped one unit of compact solids removal unit to our international client for core drilling in mining industry. This is the 3rd unit of solids removal unit in that area since the last shipment in July, 2015. The client who bought 2 units of solids removal units gave us some feedback and suggestion, we welcome our customers to give us comments to improve ourselves. We made some amendment and improvements according to their suggestions.
The updated design of solids removal unit is more compact compared with before, the complete design is only 2800x2100x2477mm， which can be shipped by 20ft standard container for sea freight. The 7.5HP centrifugal pump is as a multi function pump for both feeding the centrifuge and mixing. This is to save area and cost for the total unit. The special designed return back pipelines is considering the flow rate of 7.5HP centrifugal pump is bigger than the mini decanter centrifuge treating capacity, if feeding too much, the centrifuge will be easily blocked, the excess fluids should be return back to the mud tank by pipelines.

The stainless steel material mixing hopper is to prevent the hopper from corrosion. The mini decanter centrifuge is the specialized model for core drilling waste water cleaning, because the water cost is very expensive, by using GN solids removal unit, the client can save lots of water consumption and save drilling cost. The 2 panel shale shaker is a mini equipments for the 1st phase cleaning of solids removal, the treating capacity is much bigger than the decanter centrifuge, because there might be a lot of big cuttings from the core drilling , which will damage the centrifuge and influence the performance of the centrifuge, so the 1st phase cleaning is very important.
For more information of GN compact solids removal unit, pls contact with GN solids control.

As a worldwide reputation brand, GN Solids Control owns its professional electrical control department to support its products line.

As most of the industry control panels should be used outdoors and some for hazardous environment. In order to ensure the longer lifetime and reliable performance at jobsite, all GN control panels are explosion proof higher than IP54. Good sealing for water and dust resistance is the basic request of ex performance. It ensures the control panel can be running reliably outdoors, especially for all kinds of drilling activities and underground constructions.

What kind of control panel GN Solids Control do make and offer?

1) Magnetic control for small power equipment ≤30kw. It is a kind of direct start for small motors. Magnetic control is widely used for solids control shale shaker, drilling fluids mud cleaner, high G drying shaker, drill mud agitators, small size pumps, drilling cuttings screw conveyers, etc…

2) For motors bigger than 30kw, direct start control panel is not suitable. Star delta starter control panel is widely used for motors ≥ 37kw. It can protect motors during starting.

3) Soft starter is another kind of control for motors ≥ 37kw. It generates a small current during starting. Compared with the start delta starter control panel, soft starter control panel is much better. It can save power. If client want use a small size cable for the motors or choose a smaller power generator, soft starter is better choice. But the soft starter control panel price is much higher than delta starter control panel.

Big pumps, vacuum degassers, decanter centrifuges, VG dryers, they have big motor. They should use star delta starter control panel or soft starter control panel.

4) Magnetic starter, control panel delta start control panel and soft starter control panel are for all fixed speed control. GN Solids Control does also offer variable speed control panels per request. VFD control panels are widely used for screw conveyer to change the transfer speed, transfer screw pump, decanter centrifuges.
