Vacuum belt filter for sludge dewatering

Continuous filtration for optimum cake moistures

Horizontal vacuum belt filters offer numerous advantages for process plants:

High filtration rates and large tonnage capabilities

Excllent washing efficiencies and lower cake moisture

Long service intervals and low maintenance costs

Applications of horizontal vacuum belt filter

Typical applications for the horizontal vacuum belt filter include:

Dewatering

Washing

Coal fines

Gold/silver recovery in cyanide process

Rutile/zircon and titanium sands

Washing of phosphate rock

Iron ore fines (both hematite and magnetite)                         

Nickel/cobalt and manganese salts

Pyrites

Uranium for SX recovery

Nickel

Potash/soda ash and lithium salts

Zinc

Acid-leached copper and cobalt

Lead

Recovery of alumina from sintered mud

Copper

Vanadium leached from magnetite

Phosphate rock

Hemihydrate and di-hydrate calcium sulfate from phosphoric acids

Washing applications

High extraction efficiencies are the key to profitability in most washing applications, whether it is for gold, uranium, phosphoric acid, copper, or alunima. The horizontal vacuum belt filter can attain wash efficiencies of more than 99.8% as plug flow displacement and multi-stage counter-current washing is utilized over the filration area.

Materials of construction

We offer a complete range of solutions for corrosive, abrasive and hot filtering applications, from the highest quality stainless steel to FPRs and plastics. The filter frames are mnufactured from open channel and angle sections to prevent problems associated with corrosion when using box sections.

Cake discharge

Cake discharge on most applications is spontaneous, we make use of cake scrapers or water slides to ensure complete cake removal in the event of wet, sticky products.

Transporter belt

We have constructed the widest filters using 4m rubber belts. These are available in natural rubber, SBR, neoprene, and EPDM, depending on the process requirements, transporter belts have a carcass-free center zone to ensure long life by preventing contact between the carcass and corrosive filtrates.

 

Working principle

Horizontal rubber belt vacuum filter with filters as the filter media, is full use of gravity and vacuum suction material to achieve effective separation of the solid-liquid separation equipment. Ring of rubber belt vacuum chamber as a whole. Drag the ring belt from motor runs continuously, filter cloth dressing on the belt and run synchronously, tapes and vacuum skid pad ring contact friction belt and the formation of the water seal. Slurryby the distributor of evenly distributed on the filter cloth. when the vacuum chamber connected to the vacuum system, forming vacuum area on the tape, landfill leachate wearing summary and transverse grooves on the belt filter cloth by a small hole into the vacuum chanber, solid particles are withheld on the filter cake formation. Liquid discharge separator into the vacuum chamber, along with the rubber band to move, cake that has been formed in order to enter the filter cake washed area and dry area, finally separating filter cloth and adhesive tape, filter cake is discharge at the unloading roller. Discharged after washing, the cloth filter regeneration of filter cake, and then through a set of back-up roll and again after correcting device into teh filter area, began to enter new filter cycle.
