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 physical properties) of the finished cement, and has a large effect upon the ...

SINOMALY produces cement raw material grinding mills in various specifications. These machines are suitable for grinding mill production lines with an output of 2500t/d, 3200t/d, 4000t/d, 5000t/d, 6000t/d and 8000t/d. The vertical grinding mill is utilized for the grinding of raw materials, mixed cement, and slag powder. Technical Parameters.
are hydraulically lifted from the grinding track before the mill motor is started. The mill can then not only be started empty but also par- tially filled with a low starting torque. Metallic contact of grinding parts on an empty or loaded mill is pre- vented by automatic lifting of rollers via a grinding bed depth control.
Vertical raw mill is important equipment widely used in the cement raw meal (cement raw materials) grinding section of the cement production process in cement plant.Because the vertical raw mill is the use of roller grinding principle to crush materials, its vertical raw mill operation is more efficient and energy-saving, product output is more stable, so in cement industry, electric power ...
Cement mill separator, or cement separator, is a type of equipment that was widely used in the cement grinding system and raw mill system of cement plants.The function of the separator is to separate the fine-sized particles from the coarse-sized particles, so as to avoid material condensation and over grinding in the mill, and improve the milling system's grinding efficiency.
Cement raw meals are sent into a cement rotary kiln to be calcined under a high temperature. After several chemical reactions are produced, some spherical gray particles, what we called clinker, are formed. In cement cooler, these hot clinkers will be cooled to a normal temperature.
