Horizontal Belt Filter

Filter Frames: Efficient Filtration Solutions

Filter Frames are precision-manufactured in standard rolled and pressed metal sections, offering durability and versatility. Materials are carefully chosen based on operating conditions and include mild steel (painted or protected), as well as various grades of stainless steel.

Transporter Belt

The Transporter Belt supports the filter cloth, featuring drainage channels and filtrate removal holes. With belt widths ranging from 500 mm to 4800 mm, it ensures longevity through a carcass-free center zone that prevents contact between the carcass and corrosive filtrates.

Rubber Grades:

Different rubber grades, such as Natural Rubber, SBR (HT or LT), EPDM, Chlor-Butyl, and Neoprene, are available based on application requirements and site conditions. The rubber selection influences the type of splice needed.

The grade of rubber, filter application and site conditions will normally determine the type of splice required. As a general guide:


Rubber curbs, bonded or vulcanized to the belt edges, prevent spillage and serve as a vacuum seal, enhancing overall efficiency.

Vacuum Box

Designed for extreme conditions, these vacuum boxes are available in stainless steel, glass-reinforced plastic, and HDPE/PP to ensure compatibility with process conditions and mechanical stresses.

Wear Strip and Wear Belt

The adoption of wear strips and belts for vacuum sealing, made from wear-resistant, low-friction materials, is an industry-standard. These strips attach to the vacuum box shoulders, locating loose wear belts.

Transporter Belt Support

Tailored support systems, such as air boxes, wear belt support stations, or stainless steel/HDPE support slides with a water film for frictionless belt movement, cater to diverse filter applications.

This can be affected in a variety of ways depending on the application of the filters

Cake Washing Applications

Achieve high extraction efficiencies exceeding 99.8% with flooded solution levels in the wash zone. The separation of wash zones from the filter table, controlled vacuum box spreads, and patented filter slope prevent forward leakage, ensuring maximum liquor concentration and recovery.

Co-Current Washing

Ideal for applications like gold and silver recovery, this method provides excellent washing efficiency with multiple stages for non-critical filtrate dilution.

Counter – Current Washing

Used when downstream treatments require minimal dilution, this method is suitable for applications such as acid leached copper, cobalt, pyrites, and recovery processes like uranium recovery and cellulose pulp washing.
