Key Benefits
- Minimise cake thickness for maximum production and cake washing efficiency and drying
- High production rate and washing efficiency
- Save on plant space and construction costs as Belt Filters can be located on one floor
- Benefit from a combination of uniform filtration, mechanical strength and chemical resistance
- Easy filtration of slurries containing fast settling solids
Increase production, lower your costs
Horizontal Belt Filters provide you with high extraction efficiency, low cake moisture, increased production and reduced operating costs while achieving maximum filtration area in comparison to other filter options.
Our filters are especially suited for applications requiring low cake moisture and multi-stage washing, allowing you to maximise cake purity at minimum specific cost. Low energy consumption and high filtration rate make Horizontal Belt Filters an excellent choice for a wide range of processes.

What we offer
Flexible and low cost
Horizontal Belt Filters can be applied to many different slurries, including fibrous materials, fine slimes, and coarse granular solids. Sizes are available up to 300m2 filtration area.
The filters maximise cake purity at a minimum cost per kilogram of product. They are especially suited for applications requiring low cake moisture and multi-stage washing. Low energy consumption and high filtration rate mean this is an excellent choice for a wide range of processes, including: Minerals processing, metallurgical ores, chemical processing, power wastes, industrial waste, food processing, and pulp washing.
Horizontal Belt Filters are ideal for your operations if:
- Thorough cake washing is required with free settling solids, complete processing of feed materials, maximum product recovery and minimum operating cost
- A flexible range of operating conditions is required
- Simplicity of operation and maintenance are required
- Process contact requires exotic construction materials.
Key benefits
Low maintenance needs, reduced monitoring
- Minimise cake thickness for maximum production
- Belt speeds up to 60 meters per minute mean fast filtration cycles that minimise cake thickness for maximum production, and cake washing efficiency and drying. By controlling the speed of the filter and process conditions, you can vary cake thickness from 4mm to 20cm.
- Low maintenance
- Heavy duty construction meets and exceeds special demands of 24 hour continuous operation. To minimise corrosion, frames are available in stainless steel as well as carbon steel. Wetted parts can be supplied in a variety of stainless steels and other specialty metals as required for process conditions. The filter cloth is continuously washed to prevent blinding. Cloth changes are accomplished quickly and easily.
- Minimal operation attention
- Filtration surfaces are visible to you at all times. Normally, only a periodic operator check is required. Alarm instrumentation can be supplied for control room reporting.
- Low installation cost
- Filters, including all auxiliaries, can be located on one floor, meaning you save on plant space and construction costs. Filters up to 100m2 have been shipped fully assembled.
Product features
Minimise unscheduled maintenance
Drainage belts
The most important component of the filter is the drainage belt. Drainage belts are uniquely designed for each application to suit the process and environment.
Important characteristics of the belt are:
- Uniform filtration
- Mechanical strength
- Chemical resistance
Years of belt manufacturing and product research have provided our engineers with expertise in vulcanisation, drainage profile, and carcass and elastomer selection.
Drainage belt carcasses are totally encapsulated in the elastomer to protect against chemical attack and carcass delamination. Carcass and elastomer selection are based on standard testing procedures and empirical data. Drainage belts are available in natural rubber, SBR, EPDM, neoprene, hypalon, and butyl. Most belt splices are hot vulcanized to maximise the strength of the splice and ensure carcass protection. Standard belt widths range from .3 to 6.5 meters.
Lowering mechanism
A pan located beneath the support belt drain holes serves as a vacuum manifold and filtrate collection chamber. On larger filters, a lowering mechanism is provided to simplify your vacuum pan inspection and maintenance. On large, severe duty filters, a counterweighted system is required to lower the pan vertically. By maintaining a parallel orientation to the filter surface during travel, this arrangement eliminates realignment difficulties and assures positive reseating. A hinged cable and capstan arrangement and mechanical pivot system are also available.
Vacuum sealing systems
Filters are equipped with a vacuum seal that prevents vacuum loss between the moving drainage belt and the stationary vacuum pan. Traveling seals are independent of the drainage belt and move relative to the top of the vacuum pan. Most of the wear occurs on the traveling seals which are easily replaced.
