The amount of dust created during slitting is of particular concern in tissue, paper and nonwovens plants, and this is especially true for producers in the hygiene industry.
This will depend on the type of product, the production process itself and the speed at which production takes place. The deposition of dust in the slitting area may reduce the cutting efficiency, contaminate the finished product and contribute to environmental pollution.
For this reason it is important to have a high-quality dust removal system in place, something that has become one of the most appreciated industrial plant retrofits.
Why do you need a dust removal system?
It cannot be stressed enough how important it is to have an adequate dust removal system on your tissue, paper and nonwovens production line. Here are the primary reasons why you must have it:
1. MAINTAIN PRODUCT HYGIENE AND QUALITY
When the product is cut, fine dust from the product is released. This dust settles on the product as it is being wound, which effectively contaminates it and compromises its overall quality. This, as we’ve said before, is especially critical for the producers of hygienic fabric and manufacturers of wearable products.
Besides the obvious hygienic issues, no one wants to open the product packaging only to find it to be covered in slitting dust, particularly the one from another product (cross-contamination).
2. IMPROVE WORKERS’ HEALTH
When dust is released into the air, it becomes a safety hazard to workers, who can easily breathe it. This can cause them both minor and severe respiratory problems, especially those who already suffer from respiratory illness, such as asthma. In addition, the accumulation of large amounts of dust in any area is a fire or explosive hazard.
3. IMPROVE CUTTING EFFICIENCY
Simply put, when dust gathers on the slitting area, it can dull the blades and prevent them from operating at peak efficiency.
4. AVOID CONTAMINATION
The effects of contamination from dust can range from plugged filters to obscured sensors on the production line. This can result in an increased need for maintenance to clean the machinery and replace filters or even an increased machine downtime, should said machine break down due to dust contamination.
How a dust removal system works
A dust removal system can be installed at any part of the production line, including:
- In-line slitting winders
- Spooling lines (for nonwovens)
- Printing lines
- Full enclosure (the dust removal system is incorporated in a self-supporting aluminium and polycarbonate structure)
The dust removal system for the slitting blade section includes suction heads that are positioned over the blade and a blower used to blow off any dust accumulation on the blade. The system also includes:
- A suction line, the power of which follows the machine rump up/down
- A fan that comes with a converter and a control unit
- Pipes and ducts to carry the dust away from the production area
- A filter to ensure dust is separated from the air
Dust removal system upgrade
A.Celli offers a solution that will turn your slitting area of the production line into a dust-free zone. The system is usually custom designed to suit a plant’s individual needs in order to collect dust from the parts of the production line that need it most. This dust removal system:
- Will not interfere with any other equipment operating on the production line;
- The captured dust will be conveyed through ducting from each of the suction boxes to a main duct;
- Ensures there is a control damper on each of the branch lines to ensure balanced operation of the system;
- Conveys air to the filter, which can be a wet or dry filter;
- Returns the clean air to the plant and the waste to the production cycle in the form of white water.
Main features of A.Celli’s dust removal system
