Sludge Dewatering Horizontal Belt Filter Press For Mine Industry

Product Description


What's the belt filter press?

The belt filter (sometimes called a belt press filter, or belt filter press) is an industrial machine, used for solid/liquid separation processes, particularly the dewatering of sludges in the chemical industry, mining and water treatment. Belt filter presses are also used in the production of apple juice, cider and winemaking.The process of filtrationis primarily obtained by passing a pair of filtering cloths and belts through a system of rollers. The system takes a sludge or slurry as a feed, and separates it into a filtrate and a solid cake.


How the belt filter press works?

Diagram of a belt filter: sludge in the feed hopper is sandwiched between two filter cloths (shown green and purple). Fluid is extracted initially by gravity, then by squeezing the cloth through rollers. Filtrate exits through a drain, while solids are scraped off into a container.

Product Advantages


Advantages of Belt Filter Press

There are many physical separation processes similar to the belt filter press used for dewatering, including centrifuges, vacuum-disc filters, and the plate and frame filter press. When compared to other compression filters, belt filters use relatively lower pressures. Although centrifuges have lower moisture content, lower costs and simpler operations in coal tails processing, belt filters tend to make less noise and have much quicker startup and shutdown times.

Belt filters are considered simple and reliable, with good availability, low staffing, easy maintenance and a long life.The belt filter is most advantageous when installed such that it is open and viewable at floor level for easier adjustment and monitoring. This is of course subject to what lighting and ventilation will allow.

Main features:

(1) Automatic control and continuous working
(2) Low energy cost and long service life
(3) High dewatering efficiency and high solid containing rate of mud cake
(4) Easy maintenance and management
(5) Low noise and less chemicals
(6) Economical and reliable, wide application.

(7) Good at dealing with Oily sludge.

(8) Water and power saving.


Product Application

Applications of Belt Filter Press

The belt filter is mainly used for dewatering of sludge and slurry and juice extraction from apples, pears and other fruits, as well as grapes for winemaking, etc. Belt filters are used both municipally and industrially in a range of areas including urban sewage and wastewater treatment, metallurgy and mining, steel plants, coal plants, breweries, dyeing, tanneries, as well as chemical and paper factories.

The applications of a belt filter are only limited to the sludges, slurry or mashed fruit that it can process. The sludges from municipal use include raw, anaerobically digested and aerobically digested sludges, alum sludge, lime softening sludge and river water silt.In industry, any sludge or slurry is sourced from food processing wastes, pulp and paper wastes, chemical sludges, pharmaceutical wastes, industrial waste processing sludges, and petrochemical wastes.These wastes can include mixed sludge, mineral slurry, dust sediment, selected coal washing mud, biological sludge, primary sludge, and straw, wood or waste paper pulp.

Some dewatering objectives include reducing the volume to reduce the transport and storage costs, removing liquids before landfill disposal, reducing fuel requirements before further drying or incineration, producing adequate material for composting, avoiding runoff and pooling when used for land applications, and optimizing other drying processes.Belt filters are specifically designed for each of these particular applications and feeds.

Applied Industries: 

1. Paper making, leather industry, livestock products industry, aquatic product industry, chemical industry and food industry.
2. Sludge concentration treatment and dewatering treatment for municipal sewer, water clarification plant .
3. Separating usage of food industry, chemical industry, mineral industry etc.
