Rubber Belt Vacuum Filter Product Introduction
Rubber belt vacuum belt filter press is an advanced continuous vacuum filtration equipment for industrial solid-liquid separation. It combines a high-strength filter belt with a fixed vacuum chamber to create stable vacuum pressure for efficient slurry dewatering.
This system is widely used in industries requiring large-capacity, continuous operation and low moisture output, especially for difficult-to-filter materials such as fine mineral slurry, chemical sludge and FGD gypsum.
Working principle
Step 1: Slurry Feeding
Slurry is evenly distributed onto the moving filter belt.
Step 2: Vacuum Filtration
Vacuum box creates negative pressure, extracting liquid through filter medium.
Step 3: Washing Section
Multi-stage washing removes impurities and improves filtrate purity.
Step 4: Dewatering Zone
Extended vacuum area enhances moisture removal efficiency.
Step 5: Cake Discharge
Dry filter cake is continuously discharged at the end of belt.
Step 6: Belt Cleaning & Regeneration
Filter cloth is cleaned for continuous stable operation.
