Disc filter for drying and filtering fine solids
Achieve unparalleled dryness and efficiency in fine solids processing with high-pressure and continuous operation, optimizing dewatering and lowering thermal drying costs for mineral and chemical producers.
Filters and Dewaters Fine Particulate Suspensions
The BoHiBar Disc Filter from BOKELA offers a robust solution for continuous pressure filtration, excelling in applications like alumina processing, coal production, and mineral dewatering. This system utilizes hyperbaric filtration, operating within a sealed pressure vessel to achieve pressure differences up to 6 bar. The unique design ensures efficient filtering and dewatering of fine suspensions, producing dry solids with significantly reduced residual moisture.
The equipment’s applications span across industries, handling end-products such as aluminum hydroxide, activated carbon, and iron concentrates. Available with filter areas up to 168 m², the BoHiBar Disc Filter supports high throughput, accommodating large volumes of slurry and cake processing.
Automation is seamless with its PLC-controlled system, featuring automated startup, shutdown, and cleaning procedures. The integration of steam pressure filtration reduces residual moisture further, while innovative wear protection components and manhole access ensure low maintenance and high availability.
Engineered for flexibility, the filter is constructed from materials resistant to corrosion, supporting longevity even in harsh chemical environments. With capabilities for customization, BOKELA provides comprehensive engineering support tailored to your filtration needs, ensuring reliable and efficient operation.
