Zhejiang Qingji Ind. Co., Ltd is one of the important manufacturers specialized in separators and centrifuges, whose main products are WestLake Disc Separator and Zhejiang-Escher Wyss Two-stage Pusher Centrifuge. Because of their excellent quality and performance, our separators and centrifuges have been honourably awarded various prizes, such as the National Invention Prize, the Sci-tech. Innovation, the Silver Medal of Quality. Our products are well sold both in China and abroad . And we have established a joint-venture in Thailand , which is responsible for sale and after-sale service around Southeast Asia.

Zhejiang-EscherWyss Two-stage Pusher Centrifuge is China's only product manufactured under the licence and whole technology from Swiss Sulzer Escher Wyss and with the certification of the Swiss Company. Series P Two-stage Pusher Centrifuge has high adaptability to filterable crystalline and fibrous products (bigger than 50um), and can successfully separate over 200 kinds of different products, f.or example, sodium chloride, sodium sulfate, sodium bichromate, ammonium sulfate, ammonium nitrate, boric acid, acetate, nitro cellulose, urea, PVC, potassium chloride, potassium nitrate, potassium sulfate, potassium carbonate and phosphate. The centrifuges are widely used in such industries as light industry, chemical industry, metallurgical industry and environmental protection.

WestLake Disc Separator can be used in the operation of liquid-solid separation, liquid-liquid-solid separation or liquid-liquid separation. Now, the separators are successfully used in the separation of latex, palm oil, vegetable oil, orange oil, yeast, fruit juice, beverage, beer and milk. Of these machines, Model Lx-460 separator is mainly intended both for the concentration of latex and for the removal of water and impurities in latex. Model QTD-350Hz separator functions in the form of liquid-liquid-solid separation or liquid-solid separation, and can be used in the operation of purification or concentration. The separated impurities can be discharged out of the machine in the controlled intermittent frequency, and the high-purity can be obtained.Model QTD-350Hz is fit for traditional Chinese medicine, vegetable oil refining, and chemical industry.
