The motor drives the roller to make the rubber belt moving forward and the filter cloth is synchronous with the rubber belt. Then the slurry (mixture) will be pumped into the feed hopper, and flow onto the flat surface of the vacuum belt filter press machine. At the same time, the material will be distributed evenly by the distributing device. Under the force of vacuum negative pressure, the liquid will be sucked out through the filter clothes, and the solid will be blocked by the filter cloth. The filter belt and filter cloth run circularly and will be washed by clean water for the next cycle. This is the whole process of vacuum rubber belt press.
Features of Vacuum Belt Filter Press Machine:
1. The vacuum belt filter is a contentious filtration device, so it has bigger capacity.
2. It can finish several technical process together: filtration, cake washing, dewatering, filter cloth self cleaning.
3. It has better filtering performance with higher efficiency.
4. Modular design, so that convenient to install and deliver.
5. Higher automation degree to save labor strength and , and can realize remote control.
6. According to technical requirement, the running data are adjustable, such as: the cake thickness, running speed, washing water consumption etc.
7. Stable working performance.
8. Easy to maintain.
