It uses gravity and vacuum suction to achieve effective separation, featuring a horizontal vacuum zone that facilitates filtration, washing, and blotting. The system is ideal for suspensions with coarse particles and high density, and it’s particularly effective in gypsum dehydration for wet flue gas desulfurization. With its modular design, long-lasting friction belt, and low operating resistance, it ensures stable operation, high filtration capacity, and low maintenance. Suitable for various industries like metallurgy, mining, chemical, and environmental protection.

Model: PBF Series
The Toncin PBF Horizontal Vacuum Tray Belt Filter is a high-automation, continuous solid-liquid separation equipment ideal for mining slurry processing. Utilizing filter cloth or mesh and vacuum suction, it efficiently separates solids and liquids. The modular design allows for flexibility in assembly and easy integration. It offers multistage washing capabilities, ensuring thorough cleaning, and can handle high-viscosity slurries with ease. The filter’s PLC control system supports remote operation, enhancing convenience. It's widely used in industries like coal washing, offering high filtration efficiency, easy maintenance, and automation for optimal performance.
Applications of Rubber Belt Vacuum Filter

FGD Projects
Rubber Belt Vacuum Filters are widely used for flue gas desulfurization (FGD) gypsum dewatering in coal-fired power plants. They are designed for continuous operation under large slurry volumes, delivering low cake moisture and stable performance in long-term, high-load conditions commonly found in large-scale power generation facilities.

Mining Industry
In mining operations, Rubber Belt Vacuum Filters are applied to the dewatering of gold, copper, and iron ore tailings and concentrates. Their high throughput capacity and operational stability make them well suited for modern mineral processing plants, where reliable solid-liquid separation is required for sustained, high-capacity production.
