Description
Mining Industry Sludge Dewatering Specialist Belt filter press for Tailings and Process Water
The DAGYEE Mining Industry Sludge Dewatering Specialist Belt Filter Press is a core piece of equipment engineered specifically for the demanding process water treatment in mining. Built to tackle the challenges of high-hardness and highly abrasive solids in mining wastewater, it delivers efficient, continuous dewatering of tailings, concentrates, and various mineral sludges through a reinforced structure, optimized filtration path, and reliable automation. It ensures the quality of process water for reuse and dramatically reduces sludge disposal costs, making it the ideal choice for modern, environmentally responsible mines.
How belt filter presses work

Enhanced Flocculation: Utilizes specialized flocculants in a high-shear mixer to form dense flocs tailored to mineral slurry characteristics.
Gravity Thickening/Drainage: Flocculated slurry rapidly releases a large amount of free water on a coarse mesh belt, boosting subsequent efficiency.
Wedge Pre-Pressing & Forming: Enters a graduated wedge zone, subjected to linearly increasing pressure to release interstitial water and form a uniform sludge mat.
High-Pressure Shear Dewatering: The sludge mat undergoes powerful shearing and compressive forces in an "S"-shaped path of multiple press rollers, removing capillary water to form a hard, solid cake.
Automatic Discharge & Cleaning: The dry cake is scraped off, and the belts are thoroughly cleaned by high-pressure jets, ensuring continuous high-efficiency operation.

Belt filter presses Advantage
BEARING FRAME Made of two very thick carbon steel plates (on request, SST), fixed to each other by means of profiles and welded to form a stiffen perfectly levelled unit. The whole structure is protected by sand-blasting type Sa 2.5, then by a zinc-aluminium alloy hot spraying and finally covered by a layer of bicomponent polyurethanic resin. Bolts and nuts are made of SST A2 AISI 304. (Ref. A)
ROLLERS The pressing, tensioning, transmission and sludge discharge rollers are protected by a layer of 8mm of rubber. The motorized pressing roller and the trajectory correction one are coated by 8 mm. of rectified rubber layer. All the rollers are supported by ball bearings type ‘Y’ which are suitably sized and guarantee a perfect impermeability. (Ref. B
BELTS TRACTION SYSTEM Models with belts width of 800, 1200, 2000 mm.: it consists of a worm motor variator with speed manual adjustment, directly keyed to the roller; Models with belts width of 1600, 2500, 2600, 3000 mm.: it consists of an epicyclic motor variator connected to a traction roller by a toothed crown and chains protected by carters. (Ref. C)
BELTS GUIDE SYSTEM Pneumatic type with proportional action probes to keep the belts continuously centered and one upon the other. (Ref. D)
BELTS TENSION SYSTEM It consists of pneumatic jacks with air springs which keep the belts tensioned. (Ref. E)
BELTS WASHING SYSTEM It consists of spray header pipes equipped with nozzles which can be cleaned by a specia plan (Ref. F)
