How to choose decanter centrifuge?

The application of decanter centrifuge in environmental protection mainly refers to the dewatering of sludge generated in the process of industrial and civil sewage treatment. Today's environmental issues have become the focus of the world's common concern, in this context, the value of decanter centrifuges has been reflected, the former sewage plants or related treatment plants are self-settling or the use of belt filter press for sludge dehydration and concentration, the test proved: Sludge moisture content from 98% to 80%, its volume can be reduced by 10 times, because of this, decanter centrifuge due to its inherent large processing capacity, automatic operation, good dehydration effect and other characteristics, in the field of environmental protection has been widely used and promoted. Decanter centrifuge single product sales accounted for about half of all centrifuge products, laying its irreplaceable status. In foreign countries, decanter centrifuges are preferred for sewage treatment equipment.
Decanter centrifuge selection
Choosing the right decanter centrifuge can not only solve the production problem, improve the work efficiency, but also save the production cost and reduce the business risk. The main factors affecting the selection are as follows:
1. Centrifuge speed: Generally decanter centrifuge should be more than 3000 RPM, the higher the speed, the higher the centrifuge separation factor, the better the separation effect.
2. Centrifuge material: different materials of its wear resistance, corrosion resistance and other physical and chemical indicators are not the same, foreign decanter centrifuge generally the lowest material is 316L, or duplex stainless steel, abrasive components must be selected ceramic synthetic materials.
3. Centrifuge differential control: different differential control accuracy is different, and the difference in life and maintenance costs is very large, the higher the differential accuracy, the better the adaptability to the material, so it is appropriate to choose the equipment with high differential accuracy.
4. Length-diameter ratio: the larger the length-diameter ratio of decanter centrifuge, the greater its processing capacity, and the smaller the moisture content.
5. Control system: Whether it is automatic programming control, domestic and foreign equipment manufacturers have basically realized the full automatic control of the equipment.
6. Installation power: affects the control of energy consumption, the general domestic equipment energy consumption ratio is high, foreign energy consumption ratio is low.
7. Processing and production technology: decanter centrifuge is a separation equipment required for high-precision processing, and enterprises without finishing ability produce products with high maintenance rate and limited processing capacity.
