Spiral pressure filter is add filler wire spiral ring, the porosity decreases, and reducing the cost of materials on the surface of the mesh.

Mainly used for press filter with belt type dryer.

Suitable for food, pharmaceutical, chemical, alcohol, vinegar industry, coal, mining, paper pulp washing, sludge dewatering and drying industry.


A belt filter press is an industrial dewatering machine which separate  liquids from bio solids/sludge. Another type of belt filter is the vacuum belt filter, this is usually a very large and wide installation for processing high volumes.  These type of belt filters are used within the water treatment industry, sewage treatment industry, food industry, mining industry, mineral industry, paper industry, pharmaceutical- and chemical industry. Those polyester wire mesh belts are built to withstand severe conditions like humidity and tension. 

Belt filter press in operation

Belt filter presses produce mechanical pressure on the slurry by sandwiching the sludge between two monofilament wire mesh belts which squeeze the water out of the sludge. The woven wire mesh belts within these belt filter presses are on high tension and follow a specific path along various rolls with a decreasing size of diameter. When the woven wire mesh belt passes the final pair rollers at the end of its path, the filter belts are separated where the filter cake (result of the pressed sludge) is scraped off, and ends up in a receiving container.

The belt filter press can basically be divided into three main areas:

1. The gravity dewater area where sludge is draining freely from water by means of gravity on a porous filter cloth belt/woven wire mesh belt

2. The wedge area where the remaining slurry is bought together by means of rollers and filter cloth

3. The pressure area where medium to high pressure is applied on the sludge in order to drain the solids intensively

Belt Filter Press

In other words, this filtration process is all about draining by pressing sludge between wire cloth belts in order to dewater the sludge for further processing.
