Pressure drum filter for fine-grained products
In industries dealing with fine-grained suspensions, achieving an effective filtration, washing, and dewatering process poses significant challenges. High process pressures and temperatures further complicate the situation, necessitating advanced solutions for optimal outcomes and minimized residual moisture.
Achieve high throughput and low residual moisture
The BoHiBar Drum Filter from BOKELA specializes in the filtration, washing, and dewatering of fine-grained or difficult-to-filter products. Operating with high filtration pressure differences up to 6 bar(g), it ensures high specific throughput and effective cake washing with low residual moisture. Its closed design provides gas-tight, leakproof operation, suitable for scenarios where contamination needs to be prevented or specific process conditions need to be maintained. The steam pressure filtration option is an innovative hybrid process that combines mechanical and thermal actions, resulting in particularly dry solids. Available in sizes with a filter area of up to 40 m², it supports continuous, fully automatic operation, making it ideal for applications such as plastic intermediates, crystallization and precipitation suspensions, and fine-grained pigments, fillers, and dyes.
Benefits
