Projects clean air technology

Especially in the case of individual plants, such as a filter plant in a quarry or similar, a supply of compressed air is not always easy to realize. For this case Münstermann supplies self-sufficient systems which are suitable for indoor as well as outdoor installation.

From time to time, it is the small projects that offer exceedingly interesting applications. A winning project in the field of air pollution control for the KIBAG ballast plant in Seewen, Switzerland, took our employees underground.

Our customer Clariant operates a bleaching earth grinding stock at the Moosburg site. The existing electrostatic precipitator has now been replaced by Münstermann with a modern bag filter system.

Münstermann has supplied a filter unit for a new Knöllinger mixing plant in Höhr-Grenzhausen. Various units such as big bag stations, mixers, ring extractors and transport containers are dedusted.

At Fels-Werke, an electrostatic filter for a drum dryer has been replaced by a modern bag filter system.

A cement production project involves the dedusting of a clay stone silo via a bag filter with compressed air cleaning. The clay is crushed in a heated crusher and then thrown over the bucket elevator and a belt into a silo.

In a project in Germany sintered filter elements are used for the separation of the finest dusts and fumes from the exhaust air of a special ceramics production. With the sintered filter elements very high separation efficiency can be achieved. A good regeneration of the elements with economical compressed air consumption contributes to a very long service life as well as the fact that it is occasionally possible to wash off the filter elements.

Two older filter systems from other manufacturers were rebuilt at our long-standing customer Jura Cement in Wildegg in Switzerland.The replacement was necessary because the procurement of spare parts and thus the reliability of the entire system has become difficult. Münstermann took over the project planning and production of the conversions.

Münstermann has supplied two dedusting plants for crushing and classifying plants for the processing of magnesite to RHI. The place of installation is in Austria. The system itself is designed for an extraction volume of 30,000 m³/h. 

A de-dusting unit is often a part of a larger plant. A recent project with Hazemag in the USA shows the importance of trust and communication between the companies involved. The project is a mobile crushing plant for a quarry, which Hazemag designed. The operator of the quarry is Lehigh Cement Company Union Bridge Quarry (New Windsor, USA, Maryland). The dedusting of this crushing plant was supplied by Münstermann. 

"Vapors" are waste air laden with water vapor, such as is the case, for example, during the drying of solids. During drying, the vapors absorb finest dust particles, which are separated in the downstream vapor filter.

A new filter system for dust removal of a dry drum for petroleum coke and pitch coke was delivered. The system runs at temperatures of up to 170 °C. Münstermann was responsible for the dismantling of the old plant, the technical design, project engineering and planning of the new plant, including all further necessary units for the operation.
