    These innovaations have made it possible to raise the production of the cement mill form 20tph up to 30tph r(200 000t annual). As a result of collaborations with the above mentioned partners the existing cement grinding technology has changed fundamentally. Therefore a shift has occured from the previous gridning technique (open cycle) to a modern (closed cycle) technique with the installation of new-generation type (O-SEPA type) separator. Within the scope of the project cement mill
