Cement ball mill and vertical roller mill are two most widely used cement mills in today’s cement grinding plants and are also the main types of cement mill we produce As a professional cement equipment manufacturer, AGICO has rich experience in the designing and manufacturing of.
In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named “conscious laboratory (CL)”. For constructing the CL, a.Cement plant motor manufacturing is one of our main product focuses. Cement mills, fans, shredders - in the production of cement, particularly large and efficient motors are required for the most diverse processes. MENZEL offers individual motor solutions for all applications in the cement.
Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and or to increase the fineness and improve defined cement properties, e.g. powder flowability.
