How belt filter presses work
-
Mobile Feeding: Mining wastewater sludge is fed into the unit via a mobile pumping system.
-
Rapid Flocculation: In a compact flocculation mixer, the sludge reacts with specialized flocculants to form large, stable flocs.
-
Three-Stage Dewatering:
-
Gravity Drainage: Flocculated sludge rapidly releases free water on the filter belt.
-
Wedge Pre-Pressing: The sludge is gently compressed in the wedge zone to enhance stability.
-
High-Pressure Squeezing: Incremental pressure from a series of press rollers forms a dry, solid cake.
-
-
Centralized Discharge & Mobility: The dry cake is discharged centrally, and the entire system is ready to be towed to the next site.

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)
Belt filter presses Features

Belt filter presses Benefits
-
Drastically Reduced Hauling Costs: In-situ dewatering converts liquid sludge to dry cake, massively reducing volume and thus the cost of transportation to tailings dams or disposal sites.
-
Zero Fixed Infrastructure Investment: Eliminates the need for costly permanent dewatering buildings, saving significant capital and time.
-
Rapid Emergency Response: Serves as an emergency unit to quickly tackle accident ponds or overflow situations.
-
Unmatched Project Flexibility: Ideal for small-to-medium mines, short-term projects, or scenarios requiring mobility between different mining sites.
-
DAGYEE Proven Reliability: Inherits the high reliability of the DAGYEE brand, ensuring stable performance in demanding mining environments.
