Hesheng's extra-large DU-150㎡ horizontal vacuum belt filter has been successfully commissioned in a single batch at a national-level chemical enterprise, demonstrating reliable performance in large-capacity phosphogypsum dewatering applications.
Phosphogypsum is difficult to dewater because of its high moisture content, poor sedimentation characteristics, and tendency to scale. To address these challenges, Hesheng redesigned the overall dewatering process using a new belt support structure, a full-area constant-pressure vacuum zoning system, and a self-balancing tubular material distribution system.
These optimizations help solve three common problems in ultra-large filtration systems: sealing difficulty across a large filtration area, uneven filter cake formation at the edges, and rapid vacuum loss caused by filter cake cracking. The result is a more stable and controllable dewatering process that helps transform phosphogypsum from a disposal burden into a more manageable resource.
For chemical and mineral processing projects requiring large-capacity continuous filtration, Hesheng provides customized horizontal belt filter for sale solutions designed around material properties, throughput requirements, and operating conditions.
