Filtration Belts

BeltTS is recognized as the leading international manufacturer of drainage belts and related rubber belt filtration products. The design and production team have created over 1,000 drainage belt solutions to support global industries requiring an efficient slurry dewatering process.

Heavy duty rubber filter belts, also called carrier belts, are used in specialized dewatering process equipment for separating solids from liquids in a slurry. These belts are highly engineered and built to very exact tolerances and specifications.

A variety of drainage hole patterns are available for different filtering applications. The drainage holes usually straddle the ribs between the two grooves, allowing one hole to drain both grooves. Hole patterns can be repeated across the width of the filtration belt if needed.

Filter belt grooves are usually one of the three basic shapes: V, Round, or U, with the V-shape being the most common. The purpose of the grooves is to transport the liquid being drained to the drainage holes. Grooves are either cut or ground into the top cover of the belt, leaving the carcass intact and protected.

Skirts increase the capacity of the filtration conveyor and help prevent spillage. Skirt styles and heights are determined for each specific application.

When the belt carcass must be protected from the liquid being filtered, we offer filter belts with fabric-free zones. These belts have the entire carcass removed from exposed areas, usually around the drainage holes and often the edges of the belt. The carcass of the belt is safely protected by a wall of solid rubber.

Many filtration belts have guides on the bottom of the belt to keep the drainage holes centered over the vacuum chamber or to aid in tracking. Several guides can be spread across the width of the belt, depending upon the number of vacuum chambers on the conveyor. Most often, the drainage holes run through both the filter belt and the bottom guides.
