GN Solids Control has been committed to the development and manufacturing of solid-liquid separation systems for many years. Just this month, GN Solids Control successfully commissioned and installed a solids control system for a domestic chemical company, which is the core equipment of the solid-liquid separation system. It is a centrifuge and some supporting equipment.

GN Solids Control is committed to the design, development, manufacturing and production of industrial separation centrifuges. GN Solids Control can produce various types of centrifuges with drum diameters as small as 220mm to 760mm. The length-to-diameter ratio of the centrifuges produced can reach 4.2. The separation factor can reach 3000G.

the development of the domestic environmental protection industry and
separation industry in recent years, GN has developed three series of
centrifuges based on the original centrifuges, namely T series, Y series, and C
series to meet the needs of different industries. Separate requirements. The
half cone angle of the GN T series dewatering centrifuge is 11 degrees, which
is conducive to the dewatering of materials and obtaining a drier solid phase.
It is often used in drilling mud, sludge dewatering and other industries; the
half cone angle of the GN Y series centrifuge is 15 It is usually used for
difficult to separate, small particles, small solid-liquid density difference,
high viscosity, low concentration soft materials; GN C series centrifuge has a
half cone angle of 20 degrees, usually used for difficult separation, small
particles, solid Materials with small liquid phase density difference, moderate
viscosity, moderate concentration, and high requirements for clear liquid
clarity, such as vegetable protein extraction, biological separation, etc.

After years of development of GN Solids Control, in order to better control the centrifuges we produce, GN Solids Control has established a professional electrical department, focusing on the R&D and manufacturing of PLC systems and electrical control systems to match the various types of centrifuges of GN. The machine significantly improves the practicability and operability of the GN centrifuge. And in order to ensure the better processing performance of the centrifuge, GN Solids Control can also match the corresponding chemical dosing system for customers.

Recently, the oily sludge treatment system manufactured by GN Solids Control has been installed and debugged at a domestic customer and officially put into production, which has been highly praised by customers.


present, due to various conditions such as different properties and working
conditions of the oily sludge treatment system in China, few equipment
manufacturers have consistent equipment. GN Solids Control has successfully
developed a set of low-cost, high-quality system equipment through market
exploration and technology research and development in recent years. The oily
sludge is separated into multiple stages through this oily sludge treatment
system, and finally the oily sludge is separated. Separated into oil, water,
solid and other products. The separated oil can be directly sold to the
refinery, and the water is repeatedly hot washed, and the oil content of the
solid phase is controlled at about 1%-3%. The oily sludge reduction process is
well completed.


This oily sludge treatment system is GNOST-05A, which processes 5 cubic meters of modulated sludge per hour. The overall system includes a feed module and a sludge vacuum pump for sludge transportation; pre-mixing module-2 sets of heating pre-mixing tanks; dosing module- The three-compartment automatic dosing system and separation module-a decanter centrifuge and a disc separator, can well complete the continuous and automated work from the feed end to the discharge end. The complete system can be operated by only 3 people. The energy consumption is low, which greatly saves the cost per ton of oil sludge treatment.

Recently, a set of sludge solidification equipment produced by our company GN Solids Control has been assembled and debugged, and will soon be sent to the geothermal well drilling construction site in a China important city to help the construction of the new area of ​​the motherland.

This set of curing equipment is mainly used for the curing of drilling cuttings, and its processing capacity can reach 15m³/h. This system is divided into two skid-mounted parts, namely the drill cuttings storage skid and the curing mixing skid. Drill cuttings storage hopper and solidification mixer are respectively installed on two skids, and the two devices are independent into skids, which is flexible in layout and convenient for shipment.

system workflow of the sludge curing equipment produced by GN Solids Control

First, the drill cuttings storage funnel is used to store and receive drilling
mud or waste, and then the material is transported to the solidification mixer
at a certain flow rate through the screw conveyor at the bottom.

The chemical agent in the chemical additive storage box is sent to the curing
mixer through a screw conveyor. In this system, the platform of the storage box
is designed with a floating platform extending to both sides, which is
conducive to the construction personnel to stack chemicals here. Additives for
easy construction and efficient work.

The materials and chemical additives are fully mixed in the curing mixer, and
the materials continue to move toward the outlet of the curing mixer. When the
materials are delivered to the outlet, the curing process has been completed.
The system also reserves a liquid phase addition port at the inlet of the
curing mixer, which can add water, acid, alkali and other chemicals required
for curing.

GN Solids Control sludge curing system is to fully mix the curing agent and the material in the curing mixer to complete the curing. During the operation of this system, the adding ratio of materials and curing agent can be set in advance. After the setting is completed, the system can be operated automatically, which greatly reduces labor costs.
