Rawmill Wikipedia

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

Factors Affecting Ball Mill Grinding Efficiency

Apr 22, 2018 Within this range, an optimum water content for efficient grinding normally exists depending on the combined effects of a number of prevalent conditions such as pulp viscosity, mill retention time, internal friction and filling of the intersticies of the charge, material transport characteristics, and the mill physical design parameters.

SAG Mill Liner Packing Grinding & Classification

Packing will result if the gaps between the liners permit it, and if the particle size produced in the mill will fit in these gaps. We see packing in our dry vertical roller mills and also in cement mills. Granted the packing is not as severe as in wet mills, as the presence of water can cause some ores to behave like a self-setting concrete mix.
