Cement production is similar all over the world. Raw material such as limestone, clay and sand and other aggregates are mined in quarries. They are ground and milled. The raw mix is fired in a rotary furnace at approx. 1,450 degrees Celsius to make clinker brick. In another mill, gypsum is added to form the end product - cement.
The pollutants released in this branch of industry is considerable. With Intensiv-Filter filtering installations, dust emissions can be lowered by more than 99%. We analyse your emission values and draw up a concept for the best economical solution for your requirements.
