Rawmill
A medium-sized dry process roller mill. A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore …

Coal Grinding
Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
A Comparison of Three Types of Coal Pulverizers
The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

Raymond® Bowl Mill designed and built for flexibility
The Raymond® Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.
Cement Roller Press
Semi-finishing grinding system: after ground by cement roller press, materials are divided into three parts through an air classifier: coarse, medium and fine, in which the coarse material is returned to the roller press for re-grinding, the medium material is put into a ball mill for further grinding, and the fine material is directly discharged as the finished …
Vertical Roller Mill in Cement Plant
Vertical roller mills have a smaller footprint, are more compact, and easier to install, making them ideal for smaller and medium-sized cement plants.
