Difficult to separate
1. Center feed, center discharge, small energy loss, it is an energy-saving horizontal spiral discharge sedimentation centrifuge;
2. Full downstream flow, full drum filled with materials, the residence time of materials in the drum is 2-5 times longer than that of ordinary horizontal screw centrifugal machine, the separation effect is significantly high, which can be applied to sewage treatment plant, and the biochemical excess sludge and mixed sludge can be effectively separated without flocculant, and the recovery rate is more than 90%. For other similar materials, better clarification effect can be obtained without or with less flocculant;
3. Because the material stays in the drum for a long time, the satisfactory clarification effect can be obtained without very high speed, with small vibration, low noise and long service life;
4. Compared with other concentration equipment, it has the advantages of high efficiency, small floor area, airtight performance, no odor and low operation cost;
5.The cost of concentration equipment can be reduced by more than 5 times;
6. Mechatronics products with high degree of automation;
7. The machine can also be widely used in the clarification, purification and concentration of suspension which is difficult to separate in chemical industry, hospital, light industry and food industry.
Lwn series concentration centrifuge is a new type, energy-saving horizontal spiral discharge sedimentation centrifuge which is further improved by referring to the similar technology in Japan. It consists of five hole drum, screw conveyor, differential, frame, shell and other components. After the suspended material enters the drum, it relies on the strong centrifugal force to make the solid precipitate and concentrate on the drum wall instantly, and the screw conveyor will transport the solid to the drum wall The precipitated solids and concentrated slurry are introduced from the sludge discharge of rotary drum, which is the first technology in China. After five years of operation in related industries, satisfactory results have been obtained.
Lwn centrifuge is the only settling centrifuge developed on the basis of LWB series. It is 5-10 times as effective as ordinary centrifuges of the same specifications in settling and separating. It is mainly used for difficult to separate materials, such as mycelium separation and nano scale material separation.
