8 Sets Inclined Plate Clarifier and 6 Sets Decanter Centrifuge for mud treatment

BY gnadmin 3 September 2023 Uncategorized

Recently 8 Sets of Inclined Plate Clarifier and 6 Sets of Decanter Centrifuge are ready for mud treatment projects, as one of the mud cleaning equipments and solids liquid separation equipments manufacturer in China, GN solids control has widely used our separation equipments for mud treatment, sludge treatment, waste water treatment, oil waste treatment, etc. industries. The 8 Sets Inclined Plate Clarifier is shipped to South America for industrial sludge treatment, the 6 Sets of high speed VFD Decanter Centrifuge are used for oil drilling mud treatment in China.

The inclined plate clarifier is firstly to be used for solids liquid separation in the oil sludge treatment system, chemicals like polymer pretreatment can improve the solids removal efficiency, it can be used based on different conditions and decide by the user. The working principal is that the inclined plate settling surfaces pitched at 55 degree angle. The solids slide down the plates in the sludge hopper, which can be transferred by a pump to solids collection box, the liquid remained in the top layer. The fluids flow to oil water separator for further treatment. The advantages of inclines plate clarifier is cheaper price, no electricity power required, simple operation, compact structure, high treating capacity, but it also with disadvantages such as lower treatment standard, it mainly used different gravity of the different materials, if the treatment result is required very high, the inclined plate clarifier can not be used.

Decanter centrifuge is one of GN major equipment, we can produce different size, different application decanter centrifuge, from 9 inch bowl to 30 inch bowl, for oil & gas drilling mud treatment, dewatering unit, oil sludge treatment, industrial waste treatment, water treatment, tailings treatment, construction mud treatment, etc.

GN Mini Solids Control Equipment for Mining Exploration

BY gnadmin 28 August 2023 Uncategorized

Recently one set of mini decanter centrifuge and mini shale shaker are ready for shipment for mining exploration.

Mining shale shaker and decanter centrifuge are major equipments of diamond core drilling solids removal unit for waste water treatment. The mini shale shaker’s function is to remove the coarse solids from the waste water, and reduce the solids content, so that the fluids feeding to decanter centrifuge can meet the feeding standard, which will improve the decanter centrifuge treatment performance. The decanter centrifuge is to remove the fine solids from the waste water and get much clean water, which can be reused for drilling. The purpose to use the solids removal unit is to recycle the water , reduce water consumption and reduce drilling cost.
If the coarse solids content is very less, a filter can be used before centrifuge to prevent coarse solids entering into decanter centrifuge, otherwise the centrifuge screw will be easily blocked and easily damaged by the coarse solids.

The 9 inch decanter centrifuge has 2 models for different applications. GNLW223 mini decanter centrifuge is the economic centrifuge for fine solids separation, the max speed is 4500rpm, and max G force is 2492G, the typical speed is 3800rpm, and working G force is 1777G, the design capacity is 130L/min, the typical capacity is 100L/min, the dewatering capacity is 1 m3/h.
When ultra fine solids required to be separated out, GNLW224F-VFD decanter centrifuge can be applied, the bowl length is 36.4 inch, the bowl length is longer for longer time clarification of material for better treatment performance. Max speed is 5000rpm, typical speed is 0 ~ 4500rpm, to reach working G force 2492G.A VFD control panel will adjust the main motor, back motor frequency to reach better treatment result.
