Specialized solutions for the recycling industry Venti Oelde

Air is the medium we work with. Research and development, planning and consulting, manufacturing and service, whatever we do, the emphasis is on innovative air technology. Venti Oelde plants and components are used for collecting, handling and filtering of air, vapours, gases, dust and airborne solids. An enthusiastic, experienced and knowledgeable team, numbering 270, ensure that individual customer requirements are implemented under economically expedient aspects. The resulting solutions are innovative, efficient, cost-effective and forward-looking. They are appreciated all over the world and...

The conceptual range of available industrial fans includes high-efficiency fans to handle gas and dust and heavy-duty fans for dust-laden process gas or clean air. These also number specially designed fans to circulate hot gas with a temperature to 1000 °C and high-pressure fans to handle gas, dust-free air, chips and other material. The field of dust collection technology includes the capture, handling and filtering of dust or solid particles out of air and process gases. The primary elements of the quotation are the planning, manufacture, assembly and commissioning of air-handling plants using...

Production waste or waste of one type represent a great resource potential if they are properly recycled. Venti Oelde has taken up the cause of processing waste before it is transferred to a recovery facility. Great emphasis is placed on hygiene in the food-processing industry. For the drinks industry, for example, PET bottles are treated in our suction type PET bottle conveying plant. This makes it impossible for residual liquid or contaminated air to leak from the pneumatic conveyor system. Fundamental to all Venti Oelde conveying and disposal systems is the wish to supply individually designed...

Special separators are used to sort the conveyed material according to the specific requirement. These are appropriate to the type of material which is being processed. Our plants convey bottles and labels from the label-stripping machine to the appropriate disposal location, where they are compressed and can be transferred to a facility where further processing takes place. The same applies to bottle tops. We are even able to generate two different products – the aluminium tops and the PE bottle tops.

The scrubber is characterised by a particularly intensive scrubbing property in a venturi pipe. The high velocity of the gas-stream in the venturi throat causes an extremely fine dispersion of the washing liquid. The water mist and dust particles meet in particularly intensive contact so that the particles are humidified and adhere to the liquid. Downstream of the venturi pipe there is a counter-current scrubber, in which the water droplets with the dust particles contained in the gas-stream are washed out. The scrubbing water can be re-used after it has been treated by means of drum screen and...

Windsifters, using re-circulated air, are used to clean the mainly ferrous metal scrap for large feed volumes up to 200 t/h. Up to about 90 % of the air is recirculated. The result is a good ferrous scrap quality and low environmental pollution achieved by considerably reducing the volume of air and dust load leaving the equipment. Pivotable discharge belts are used to discharge the ferrous fraction so as to obtain a large stockpile volume. Special lifting magnetic drums separate the iron fraction from the non-ferrous metals and heavy waste material. The waste fractions are automatically discharged...

Venti Oelde offers concepts to obtain a concentration of metals or to generate very pure metal contents for the so-called shredder heavy fraction produced by large shredders. By separating these valuable materials into their original component parts it is possible to obtain higher profits when selling the reclaimed secondary raw materials. Together with our customers we design complete plants to process metals, for example, electronic scrap, shredder fluff and shredder heavy fraction and cooling scrap. Because of the various milling and separating components our Multi-Metal-Separating Plant is...

Treatment of waste and generation of secondary fuel No matter whether waste is bio-mechanically pre-treated or burnt, it is advisable in any case to separate out any impurities. Venti Oelde offers a number of different air classifying systems, so-called separators. These are characterized by using recirculating air and by their capability of handling large volumes. New developments such as the large particle separator complete the spectrum. Even when bio-mechanical processing at a later date in waste processing plants is planned to produce secondary fuel, these classifiers are useful to generate...

As a result of the increasingly stringent legal requirements and costly treatment processes the whole dust collection and air handling field in waste processing plants has gained in importance. Venti Oelde applies its know-how in the handling of air and collecting of dust here. As well as simple filter plants and wet scrubbers we also supply large and complex dust collection plants, if necessary with precoating plants for the various cleaning systems. Furthermore, we support the general contractor in building special plants, by developing specific air management concepts to minimize air volumes...

Hot, dust-laden oxy-fuel gases, produced, for example, when breaking up slagblocks or cast blocks from converter or blast furnace smelts, are effectively captured, exhausted and dedusted before they are discharged into the atmosphere. Capture hoods, appropriate to each process, efficient exhaust plants and high-capacity filter plants assist in the fight against dust and in transforming slag-block gas-cutting work-places into clean and humane workplaces. Specific capture and the planning of pipes and ducts and their layout are also included in Venti Oelde’s supply scope. We select the appropriate...
