Features of GNLW224EP-VFD Decanter Centrifuge:

1. The large and small end cover shafts, rotating drums and spiral mandrels are made of duplex stainless steel SUS2205 by centrifugal casting, and their performance is better than SUS304 and SUS316 in the same industry.

2. The main parts are made by centrifugal casting and die forging technology to avoid the quality defects of intergranular corrosion and incomplete residual stress release caused by traditional welding technology.

3. The main material of the screw pusher is made of duplex stainless steel SS2205, SS2304 or higher material, and the spiral blades are integrally pressed by CNC spiral blade forming equipment to improve the efficiency of screw slag conveying.

4. The slag discharge port is protected by a replaceable hard alloy sleeve. The top and side of the slag discharge port of the drum are installed with cemented carbide scrapers, which can effectively protect the drum and prevent wear. The 360-degree rectangular slag discharge port, slag discharge Smoothly prevents clogging.

5. According to the material handling requirements, the spiral can use BD baffle to separate the dewatering zone and the settling zone deeper, and the dewatering zone is longer.

6, PLC control panel control, the sensor can be placed on the centrifuge to monitor the state of the machine.

Recently, a set of sewage treatment centrifuge with dosing device produced by GN Solids Control will be sent to customers in the Middle East. The centrifuge of this project adopts intelligent, automated, and efficient customized design according to customer requirements. The machine trial effect is very satisfactory.

Features of chemical dosing equipment:

1. Three tanks in one (mixing tank, mixing tank, storage tank) continuous brewing, easy operation and maintenance, low labor cost; according to actual needs, it can be changed to double tank type to make it more economical and reasonable;

2. The machine has the function of proportioning allocation, which can adjust the concentration of liquid medicine required for brewing according to actual needs;

3. The brewing concentration of this machine is uniform and moderate, which can reduce the occurrence of granulation caused by improper manual deployment, which will block the pipeline or pump, and increase unnecessary maintenance costs and powder expenditure;

4. The fusion effect of the medicine and liquid mixer reaches 100%, with unique innovative functions;

5. The machine is uniquely designed with stand-by time and automatic intermittent and paused cross-stirring functions, so that the infusion solution can be uniformly blended and kept in the best use state forever; when the powder supply tank is low in stock, the indicator of the appliance is detected by induction The function assistance of warning and stopping of the dosing pump makes the overall controllability of the machine more perfect.

Features of GN Solids Control 454E series decanter centrifuge:

1. The drum is made of duplex stainless steel SS2305 by centrifugal casting, and its performance is better than SS304 and SS316.

2. The centrifugal casting process makes the drum more uniform in texture and has good dynamic balance performance.

3. The slag discharge port of the centrifuge and the slurry outlet of the screw pusher are inlaid with tungsten carbide cemented carbide sleeves, which are extremely wear-resistant and not easy to break.

4. The screw pusher is inlaid with wear-resistant alloy sheets, which has a longer life and reduces the number of maintenance.

5. PLC control panel control, sensors can be placed on the centrifuge to monitor the status of the machine. GN Solids Control focuses on the R&D and manufacturing of separation and conveying equipment. E series decanter centrifuges are mainly suitable for solid-liquid separation of mineral oil, chemical viscous materials, fruit juice, coffee, tea, wine, soy milk, biodiesel, starch, etc.

Recently, a set of construction slurry treatment system produced by GN Solids Control has been put into use in construction mud treatment stations in North America, and the system has been successfully introduced to the international market, and will soon be sent to foreign customers, including the Middle East, Southeast Asia and other regions Engineering construction unit. The system has the characteristics of small footprint, low cost, and significant treatment effect, and can also be widely used in tunnel shield and pipe jacking projects and trenchless directional crossing projects.

This mud separation system is mainly composed of four solid-liquid separation modules: coarse screening, vibrating screen, desanding and desilting cyclone and decanter centrifugal dehydrator. Its working principle is as follows:

1. The mud tanker transports the mud produced by urban construction to the treatment station. First, the big rocks are filtered out through the collecting funnel, and then the small rocks are screened out through the coarse screen. The remaining mud is filtered and collected to the transfer station. In a jar

2. The slurry supply pump pumps the slurry from the transfer tank to the vibrating screen for further solid phase separation and removes the large particles of sand and gravel;

3. After the mud passes through the shale shaker for preliminary solid-liquid separation, it is pressurized to the desander cyclone by the slurry pump in the system. After high-speed cyclone separation, the grit components with a particle diameter greater than 40 microns are removed, and the fine sand is separated into the transfer tank, and then pressurized by the slurry supply pump to the desilting cyclone. The desilting cyclone will be more than 20 microns The particles are separated, and the mud below 20 microns is returned to the mud storage tank and pumped to the construction machinery for recycling after reproportioning.

4. The high-speed centrifugal dewatering centrifuge equipped with this system can separate the fine particles of 5-20 microns in the mud to ensure the performance of the mud.

Centrifuges produced by GN Solids Control are widely used in drilling mud treatment, sewage environmental protection treatment, oily sludge treatment, chemical and food and beverage industries.
