Integrated Mechanical Belt Thickener
1. Sludge inlet moisture content: 98%~99%, sludge outlet moisture content: 92%~96%.
2. Equipped with self-cleaning spray nozzles, saving approximately 30% on rinse water.
3. The self-developed sludge scraping baffle ensures even distribution of materials, reducing the dosage of flocculants by about 20%.
Product Introduction
1. This machine features a specially designed large-diameter arc dewatering technology in the transitional dewatering zone, which gradually increases the pressure on the filter belt, effectively preventing the phenomenon of sludge leakage, thereby greatly enhancing the sludge processing capacity.
2. The compact frame design with S-shaped installed guide rollers reduces the overall volume of the machine and improves dewatering efficiency.
3. The thickener has a simple structure, low fault rate, stable operation, and special filter mesh selection, resulting in significant pre-dewatering effects.
4. The addition of a "dummy roller" device makes pre-press dewatering more stable and effectively prevents sludge leakage.
