GN Separation Equipment Manufacturer

This week, GN completed the assembly and factory test of two GNLW454 decanter centrifuges. The equipment rotation bowl is 450mm and the rotating speed can reach 3500RPM. Later the equipment will be sent to European client for municipal sewage treatment.

In the process of municipal sewage treatment, it is necessary to precipitate the sewage to be treated, and then dewater the sludge in the sedimentation tank to facilitate the transfer and re treatment of sludge. GN ET series dewatering centrifuges are designed based on sludge dewatering, which can meet the requirements of users to adjust the running speed of the equipment according to the dryness of slag discharged and the clarity of liquid discharged during the machine running, so as to achieve better treatment effect.

GN sludge dewatering centrifuge has the following characteristics:

1. The equipment adopts dual motors to drive the bowl and screw respectively, and realizes solid-liquid separation by adjusting the differential speed. The dual motor is installed at one end of the equipment, with reasonable structure, which is convenient for personnel to operate and maintain the equipment.
2. The collection box is made of stainless steel, and the upper cover is equipped with gas spring, which can be easily opened for maintenance.
3. The upper cover of the collection box is designed with flushing water inlets, and nozzles are installed inside the upper cover to flush the outer wall of the bowl and the slag outlet.
4. Considering the working condition of municipal sludge dewatering, GN provides wear-resistant protection for the parts inside the centrifuge that contact with sludge. For example, a tungsten carbide protective sleeve is installed at the material distribution port of the screw, the screw blades can be protected by tungsten carbide alloy plates or built-up surfacing, and a tungsten carbide protective sleeve is also installed at the sludge cake outlet of the drum.
