Together with one of our customers, Haver Niagara from Münster we have undertaken the dedusting of a dry mortar plant in Adwan in Saudi Arabia.

Planning and production of the filter plants by Münstermann

The Haver Niagara conveyor belts and screening plants were dedusted using the Type SK36 bag chamber filters. The bag filter is equipped with a fully automatic compressed air cleaning system. This system serves to recover dry dust and purify gases. Münstermann produced the filter system itself. The 3-D planning of the pipelines was also completed out by us however the production of the piping was carried out locally. Assembly and commissioning was the responsibility of Haver Niagara. Münstermann trained the technicians from Haver in advance.

Compressed air cleaning

The compressed air pulse for cleaning in each respective filter bag ensues from the use of servo-assisted diaphragm valves. Each filter module has its own compressed air tank with diaphragm valves, control valves and piping. Short electrically controlled compressed air pulses clean the rows of filter bags. The cycle times and pauses are variable and can be adapted to suit the operating conditions. The pulse rate is fixed in such a way that the installed filter surfaces are well cleaned.

A satisfied customer

Adwan has been happy with the filter units from Münstermann and their quality for years. We have frequently supplied Haver with goods and services in the past – not through Haver Niagara but through Allgaier for the dedusting of the drying drums. The quartz sand has to be dried before it is mixed with cement or paint etc. Even desert sand contains a certain amount of residual moisture.
