ARIOSA: the dust removal system that protects leather quality

How often, during the tanning process, have the quality and value of the leather been compromised because of dust?

At certain times of the year, dust is a real headache for those who work with leather. Not to mention the problem of static electricity, which sometimes makes it impossible to work at all.

BERGI SpA has long been committed to this cause, waging a full-scale war against dust.

There are various types of powder used in tanneries: emery dust, which is the most common, flesh-side fibre dust, and ambient dust.

Per la polvere da smerigliatrice ad oggi abbiamo sviluppato 5 varianti di depolveratrice ad aria mod. ARIOSA da 3 a 6 teste soffianti e, in numero superiore, teste aspiranti. In entrata o in uscita alla depolveratrice in alcuni casi suggeriamo l’applicazione di una spazzola rotante per smuovere la polvere fissata in profondità.

Typically, when purchasing a grinding and dust removal line, secondary factors such as the type of blower, the distance between the machines and the suction system, the diameter of the suction pipes, how many bends, the difference in height, etc. are underestimated. These are all factors determined for successful skin cleaning. So when you buy a grinding line or a single dust collector it is good to know from the beginning where the machine will be placed and where the suction system is located. It is clear that the closer they are the easier the dimensional calculation. On the other hand, if you plan to install a spark detection system in the intake air pipes, you need to calculate the air velocity and place an automatic damper at a safe distance from the detector to block the air flow and prevent the spark from entering the dust collector. This distance is always greater than 20 linear meters.

To deal with the fibre dust on the flesh side that is usually generated by rubbing, BERGI SpA has designed a range of dust extractors that can be positioned, or even installed, in front of or behind various production machines, such as: behind the stacking conveyor before stacking, in front of the spray finishing line, a rotary pad printing machine, or a press for finishing or intermediate printing. Fixed or mobile dust collectors, depending on the customer’s specific requirements on a case-by-case basis.

For environmental dust, the solution is usually the same as just mentioned above: this is normally created by incorrect use of certain processing steps, such as for example personnel who introduce the hides onto a finishing line or press to iron and print and with the jet of compressed air constantly blows the hides, by moving the dust from the skin in his hand but moving it to another part of the environment and then systematically returning to the starting point.

There are also specific systems for air recirculation in the environment with collection filters and low-energy impact engines.

All this must be treated after careful on-site advice so as not to risk a half-baked investment.
