Applications for Kiekens Products

The Kiekens central dust extraction systems

You will encounter them in all sorts of locations, wherever dust and dirt need to be extracted fast and efficiently: offices, schools, public institutions and the like, or in places where vacuum cleaners cannot reach, or where severe noise restrictions are in force, such as hospitals.

In industrial companies, too, a central dust extraction system is ideal for removing dust and dirt without having to drag vacuum cleaners all over the place. This will help you save cleaning costs and create a better and healthier climate.

1. How can multinational enterprises solve office cleaning issues?

A clean working environment is an important factor in any company's employment working conditions policy.
If your office covers six floors (around 10,000 square metres plus sanitary spaces), how on earth are you going to work out a system to keep all those spaces clean?

The Kiekens solution: A semi-automated central dust extractor system. In this case, semi-automated means that the filters are beaten clean automatically after use.
A company building of this size offers the possibility of fourteen simultaneous extraction points.
The dry dust is collected in separators, and the purified air is exhausted noiselessly. The key concepts of this solution are reduced workload and workplace optimisation.

2. How can chemical factories save on cleaning costs?

In one of the factories of a large chemical company, plastic raw materials are processed into semi-manufactures. The waste produced during the manufacturing process must be removed regularly in orde to minimise stand-still times.

The Kiekens solution: A fully automated central extractor system with several hundreds of extraction points in the factory, allowing sixteen people to work with the system simultaneously. The Kiekens solution is extremely user-friendy, so that the operators are able to keep the workplace, the production equipment and the factory clean with very little effort.

Vapour exhaust and recirculation of clean air
In spaces where industrial production processes take place, the air is often full or noxious fumes that have an adverse effect on working conditions (by settling on the equipment and products, reducing visibility, etc.). Worse still, the fumes may be very unhealthy and unpleasant for the people working there. In most cases the solution is obvious: Kiekens provides vapour exhaust systems (made-to-measure or with standard components) that are suitable for virtually any process where unwanted vapours and mists are produced. By supplying fresh and clean air, the Kiekens systems will greatly improve the working climate in previously unpleasant and unhealthy work areas.

3. Vapour exhaust and recovery of raw materials

The galvanisation of tubes produces unpleasant vapours. Also, the addition of powders to the zinc bath is a potential dust nuisance. Note, moreover, that the zinc dust produced further down in the production process might generate a fair amount of extra income if it could be recovered.

The Kiekens solution: An extensive installation comprising two different sections. The first section exhausts the vapours and collects the dust using a self-cleaning filter. The second section collects the zinc dust. Additional heating will prevent the dust and zinc from sticking together.
Coarse and fine zinc particles are separated using an intermediate separator. The collected zinc dust is sold to the paint industry and helps recover much of the cost of the installation.

4. How does Kiekens succeed where others fail?

A well-known seed supplier has built a new machine shop for seed cleaning activities. After some time, the exhaust system appears to be unable to meet the extremely stringent purification requirements. The supplier decides to call Kiekens.

The Kiekens solution: First measure and determine the conditions. As new systems would be too expensive, the question is: How to upgrade the existing installations to the required standards? In the end it is decided to install new pipelines to improve exhaust capacity, and to place three new dust filters.
The ventilation problem is solved by improving the air supply. This solution guarantees highly improved working conditions for the employees in the machine shop.

5. Dust-free shipment of bulk goods with the use of grab cranes

The sudden release of, say, 10 m³ of tapioca from a grab crane into a storage funnel will produce an enormous cloud of dust, which may harm both human health and the environment. This type of handling also causes a great deal of raw material to be lost.

The Kiekens solution: A dedusting installation with an exhaust point inside the bunker, to prevent dust from escaping into the outer air. The filter chambers are united with the bunker.
A recirculation system is used to transport trapped dust particles back into the funnel section. The product is placed on mechanical vehicles for transport out of the bunker; Kiekens also provides dedusting solutions at strategic points along the route.

Dust-free pneumatic transport
The manual supply and transport of raw materials in production processes often generates a great deal of unwanted dust. However, there is an excellent solution to prevent that problem.
Kiekens pneumatic transport technology ensures the efficient, environmentally friendly and dust-free incorporation of raw materials into the production process.
Dust formation and loss of raw materials belong to the past thanks to the Kiekens pneumatic transport circuit. Once again, Kiekens offers the best solution!

6. Toothpaste production that does not leave a bad taste

Chalk is one of the key ingredients of toothpaste. Incidentally, it is also one of the most difficult raw materials to process in a dust-free operation. In addition, chalk has a tendency to stick to people's shoes, which means it will spread through buildings in no time. This, in short, was the problem faced by one of the leading toothpaste manufacturers before they consulted Kiekens.

The Kiekens solution: A dust funnel placed outside the production hall, from where the chalk is transported to the mixing pans inside the production hall through a pneumatic system. A facility installed above the mixing pans prevents the chalk from dusting when being fed into the pans. The chalk residues in the return flow are conveyed back into the production hall through a filter.
In addition to eliminating the dust problem, our solution has streamlined the product supply for this manufacturing process.

7. Fighting sand nuisance in a brickworks

In modern brickworks, bricks are baked in a fully automated process which involves a risk of the clay sticking to the moulds.
In order to eliminate this risk, the moulds are sprinkled with dry sand. The downside is that this method produces dust and high machine abrasion rates.

The Kiekens solution: Exhaust and collection funnels are placed where the dust is created. The systems are connected to the steel pipeline (with reinforced bends) of the central extractor system.
The dust collected is transported to a dump. The result: machines will not get jammed and suffer very little wear, cleaning times are reduced considerably and the production staff are no longer bothered by stray sand.
