In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and ...

Cement kiln - Wikipedia

Portland cement clinker was first made (in 1825) in a modified form of the traditional static lime kiln. The basic, egg-cup shaped lime kiln was provided with a conical or beehive shaped extension to increase draught and thus obtain the higher temperature needed to make cement clinker. For nearly half a century, this design, and minor ...
