Classic and efficient models - a reliable choice for large-scale production
DU type rubber belt vacuum filter: continuous horizontal vacuum filtration technology, with a processing capacity of 10-50t/h, suitable for large-scale continuous dewatering scenarios such as mining (iron concentrate, copper concentrate), metallurgy (steel slag, concentrate), etc;
PBF/XU belt vacuum filter: modular structure design, flexible adaptation of filtration area (5-30 square meters), covering medium production capacity needs such as chemical (catalyst recovery), food (starch clarification), etc;
2. Customization for Special Scenarios - Precise Matching with Strict Requirements
XU fully sealed vacuum filter: fully welded sealed structure+double-layer vacuum chamber design (vacuum degree ≥ -0.09MPa), air leakage rate<0.1%, specially designed for fields with strict environmental requirements such as fine chemicals and pharmaceuticals, ensuring low moisture content of filter cake and high purity of filtrate;
DNY type concentration and dehydration integrated machine: integrates concentration and dehydration dual functions, improves process efficiency, and is suitable for environmental protection (municipal sludge), electricity (desulfurization gypsum) and other scenarios that require reduction treatment;
3. Deep Dehydration Technology - Solution for Low Moisture Content Requirements
DZY type belt press vacuum filter: With the synergistic effect of vacuum suction and mechanical pressing, the moisture content of the filter cake is as low as 18% -22%, suitable for deep drying needs of high humidity materials in chemical industry (such as dye filter cake), municipal sludge, etc;
4. New technology models - leading the future of the industry
He series belt vacuum filter (newly developed in 2025): Integrating AI intelligent control with special filter belt materials, optimizing separation efficiency through real-time monitoring and adaptive adjustment, reducing energy consumption by 15% -20%, and redefining industry solid-liquid separation standards.
