Belt Filter Cloth for Vertical (Tower) Press Filters | Larox Filter Cloth

larox vertical press filters

The vertical tower press belt filter cloth is the specially designed filter element of the vertical tower belt filter machine, for example, Larox vertical tower press filter. It’s one piece continuous filter cloth in “Z” shaped between the filter plates group. The belt filter cloth deployed between the filter plates horizontally. During the press filtration process, the filter plates group are pressed together, then pump the slurry into the filtration chamber, the filtrate reaches through the filter cloth, and the solid particles are retained on the filter cloth to form a filter cake. Then open the filter plate group and discharge filter cakes.

The vertical tower press filters are widely used in the washed mineral of heavy non-ferrous metal, especially for the large throughput and fine particles of difficult to filter, and filter cake moisture request lower than 10%.

The working conditions require the belt filter cloth for a vertical tower press belt filter should be in excellent filter performance to capture the fine particles, good conveying for large volume filter cake, abrasion resistant for metal prills and scraper, chemical resistant for chemical solvents, and excellent mechanical strength for enduring the tensile of the driven & tension roller, furthermore the belt filter cloth should be good heat set to ensure the stable dimension and low elongation. Generally, the tension of the belt filter cloth on a vertical tower press filter is about 5kN.

vertical press filters-z shape filter cloth

The special “Z” shape of this kind of belt filter cloth fixed on a vertical tower press filter request the cloth has a significant difference from other belt filter cloths, it has the same weave structure on both sides, double-sided filtration, and double-sided cleaning.

How to choose the belt filter cloth for your Vertical tower press filters?

1. Define the ideal material and fiber

Material and fiber Properties
Polyester monofilament filter cloth Made of high-strength, low-stretch polyester monofilaments. Smooth surface for easy cake discharge, acid-resistant, wear-resistant and high-strength, anti-blocking, easy to clean, and regeneration. The normal use temperature is less than 130 °C (266 °F), and the instantaneous use temperature is 150 °C  (302 °F).
Polyester multifilament filter cloth The series of filter cloth is weaving by the polyester filament in multi-strand. It is acid-resistant, high strength, better intercept ability for fine particles, but more difficult to clean than monofilament due to the multi-fiber. The normal working temperature is no more than 130 °C (266 °F), and the instantaneous working temperature is 150 °C  (302 °F).
Polypropylene (PP) monofilament filter cloth Made of polypropylene high-strength monofilament, smooth surface for easy cake discharge, acid and alkali resistant, hydrolysis, oxidation and mildew resistant. The normal working temperature of PP filter cloth is less than 90 degrees Celsius, and the instantaneous use temperature is 90°C (194 °F).
Polypropylene (PP) multifilament filter cloth Made of polypropylene monofilament in multi-strand, smooth surface, acid and alkali resistant, hydrolysis, oxidation and mildew resistant, high strength, better intercept ability for fine particles, but more difficult to clean than monofilament due to the multi-fiber. The normal working temperature of PP filter cloth is less than 90 degrees Celsius, and the instantaneous use temperature is 90°C (194 °F).

2. Select the optimal weave

Plain weave filter cloth

a. Plain weave: the most primordial and simplest weave, more interweaving points, compact and firm structure, small porosity and hard texture, medium cake release, easy blinding.

twill weave

b. Twill weave: The twill weave has less interweaving points, less robust than plain weave, but still stable in transverse and good mechanical strength, more smooth surface and filter cake release easily.

satin weave

c. Stain weave: The warp and weft threads have less interlacing points, loose structure, soft texture, the smoothest surface for cake release easily, and relative lower retention ability.

3. Choose the suitable air perm

High air permeability has higher filtration efficiency but lower particle retention, small air permeability could get better particle retention but filtration speed decrease. We will help to choose the most suitable type of filter cloth to get your optimal filtration production.

The air permeability was depended on the yarn density and decide the filter fineness as well as the filter efficiency.

The multifilament or multifilament / monofilament mixed belt filter cloth is most commonly used on the vertical tower press filters, due to its extremely high tenacity and better capacity of particle retaining. Both sides twill weave makes the cloth has smooth surfaces, for easily filter cake discharge.
