The rubber belt vacuum filter uses filter cloth as the filtering medium, relying on vacuum negative pressure to achieve efficient solid-liquid separation. This equipment features a simple structure, low manufacturing and operating costs, and is easy to maintain and operate. The production process runs fully automatically, allowing for flexible adjustments of operating speed, feed rate, and wash water volume based on production needs. Widely used in industries such as power generation and environmental protection, mining, chemical, metallurgy, papermaking, food, pharmaceuticals, and coal.
