Product Details

　The paper-belt filter consists primarily of the following components: a liquid tank, a dirty-paper collection bin, a nonwoven filtration medium (commonly referred to as the “paper belt”), a drive mechanism, an alarm unit, a reducer, and a liquid pump. During operation, the chain and wire mesh of the drive mechanism are arranged in an arcuate configuration, and the nonwoven fabric laid over them also assumes an arcuate shape. When contaminated liquid containing impurities is sprayed onto the nonwoven fabric, fine chips and other contaminants are adsorbed onto its surface. As the accumulated dirt on the fabric increases and eventually clogs it, the liquid level rises, triggering the float-type level controller to send a signal. The alarm unit then activates, causing the reducer to drive the chain and wire mesh, which in turn discharges the accumulated dirt and used fabric into the dirty-paper collection bin. This process automatically replaces the filtration medium. Once the filtration medium has been renewed and the liquid level drops, the machine stops rotating, thereby initiating the next filtration cycle. The clarified liquid entering the liquid tank is then pumped by the liquid pump to the main processing unit.

　　The filter manufacturer’s products are capable of thoroughly removing all types of metallic and non-metallic fine impurities from coolant (oil), making them particularly suitable for precision machining equipment such as grinding machines and honing machines. When contaminated fluid lands on the filter cloth, fine chips and impurities are adsorbed onto the surface, where they themselves become part of the filtration layer, thereby enhancing the filtering performance. Moreover, because the filter cloth operates in an arc-shaped configuration, this design not only increases the effective filtration area but also reduces the footprint. When the filtered liquid contains a high concentration of magnetically attractable impurities, a two-stage filtration process can be implemented by adding a magnetic separator: first, the separator removes most of the magnetic impurities, and then the filter cloth completes the final filtration. This approach effectively reduces filter cloth consumption and improves overall filtration efficiency.

Features of the Paper Belt Filter

01

The paper-band filter is highly effective at removing fine metallic and non-metallic impurities from coolant (oil), making it particularly suitable for precision machining centers such as grinders and honing machines.

02

When contaminated liquid falls onto the filter cloth, fine chips and impurities are adsorbed onto its surface; in turn, these particles themselves become part of the filtration layer, thereby enhancing the filter cloth’s filtration performance.

03

Because the filter cloth operates on a curved surface, it both increases the filtration area and reduces the footprint.

04

When the liquid to be filtered contains a high concentration of magnetically attractable impurities, a two-stage filtration system can be implemented by adding an additional magnetic separator: first, the magnetic separator removes most of the magnetically attractable impurities, and then the remaining particles are filtered through a filter cloth. This approach effectively reduces filter-cloth consumption and enhances filtration performance.

Scope of Application

Hebei Rui’ao’s belt-type paper filter is particularly well suited for purifying coolant in a wide range of grinding machines, precision lapping machines, wire-drawing machines, electrical machining equipment, and other fine-machining tools; its most common application is the separation of metal chips and swarf. The primary market for magnetic separators comprises machine tools such as lathes, grinders, and planers, where they are used to separate metal chips and swarf generated during machining operations—including industrial waste and intermediate chemical products that require iron-removal processes. With the increasing use of aluminum products in the market, the volume of aluminum chips produced is inevitably growing, and if ferrous contaminants are present, these materials cannot be properly recycled or reused—making magnetic separation essential. Magnetic separators are also widely employed in the refining of copper powder and other nonferrous metals. Typical applications include surface grinders, precision grinders, deep-hole drilling machines, honing machines, internal and external cylindrical grinders, centerless grinders, thread/gear/bearing grinders, wire-cutting machines, and machining centers.

Performance and Applications of Magnetic Roller Belt Filters

This unit is a combined product of a paper-band filter and a magnetic separator, and should be given priority when machining magnetizable workpieces on grinding equipment.
