At HÖCKER, energy efficiency is not just a fashionable phrase."

Since the 1980s, HÖCKER Polytechnik has been supplying the Klingele-Werken [Klingele Factories?] with energy-saving plant for process waste disposal.

For more than 25 years HÖCKER Polytechnik has been the supplier of the technology for paper and corrugated fibreboard disposal to the Klingele company.
Many different plant types, from waste and dust extractors, to ventilation and conveyor belts have been installed in the past in the various production facilities.
As a result of the extensive modernisation work in the Klingele Group, improvements and expansion of our extraction and conveying equipment or even complete new systems became necessary.

In the Hilpoltstein, Werne, Delmenhorst and Grunbach / Remshalden factories, the complete waste disposal technology was revised, planned and implemented.
The Klingele company places particular value on environmental protection and cleanliness; the production techniques of existing and also new processing machines was rationally altered so that waste disposal could be done principally by means of large conveyor belts. For the most part, the conveyor belt systems were installed in new underfloor channels. The waste material is then fed into the channel balers via an inclined conveyor.

This method of waste disposal produces little dust and is energy efficient. The edge strips from the corrugated fibreboard units are also partly disposed of in the same channel balers by a suitably-adapted extractor system.
By reducing and adapting the extractor units (using an underpressure system) permanent savings can be made in energy and heating costs.

Special material separators and filters were employed which enable smooth separation and filtering of the materials and dust from the air.
Furthermore, Klingele invested in dust briquetting presses by HÖCKER Polytechnik. These automatically dispose of the accumulated dust from the filters and compress it into manageable briquettes.

On many of the processing machines decentralised dust extractors were installed. This is where the extracted air or inserts are cleaned of dust or extracted by suction. To avoid long duct distances, in certain places small filter units were set up in the production at each machine in order to ensure low-dust and pleasantly ventilated workplaces.

In addition, at the Delmenhorst Factory, as an intermediate solution before the future completion of the extension, a combined shredder-conveyor system was installed. Here the waste from the stamping machines is fed directly into a slow-moving shredder via an underfloor conveyor. From there the shredded material is transported by means of the existing air extraction system to the balers. When the installation is completed, the shredder will be replaced by a suitable inclined conveyor to the baler.

Since in several factories the upgrading required a period of several months while normal operation continued, several building sections were necessary. Precise agreement and numerous site visits with perfect coordination regarding the individual work sections and binding installation dates were needed to carry it all through. All the planned objectives to keep to schedule and to minimise lost production time were achieved by the parties working together.

All the extraction and conveyor systems delivered were planned so that in the future they can be easily and economically extended at any time in the individual factories.
