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, thereby automatically replacing the filter cloth. Once the filter cloth has been renewed and the liquid level drops, the machine stops rotating, 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 comes into contact with the filter cloth, fine chips and impurities are adsorbed onto the surface, where they themselves form part of the filtration layer, thereby enhancing the overall filtration performance. Moreover, because the filter cloth operates on a curved surface, this 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 the majority of these magnetic impurities, and then the filter cloth completes the final filtration, which effectively reduces filter cloth consumption and improves 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 grinding machines and honing machines.

02

When contaminated liquid falls onto the filter cloth, fine chips and impurities are adsorbed onto its surface, thereby becoming part of the filtration layer and enhancing the filter’s overall filtering 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 process 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 the 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 precision machining tools; its most common application is the separation of metal chips and swarf. The primary market for magnetic separators is mechanical machining—specifically lathes, grinders, planers, and similar equipment—where they are used to separate metal chips and swarf; they are also employed in processes that require iron removal from industrial waste and chemical intermediates. With the increasing use of aluminum products in the market, the volume of aluminum chips generated is inevitably growing, and if ferrous contaminants are present, these chips cannot be properly recycled or reused—this is precisely when a magnetic separator is needed. Magnetic separators are also widely used in the refining of copper powder and other nonferrous metals. Commonly applicable machinery includes 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.
