14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.

This article will describe the different parts of a CNC machine. Some parts are common between lathes and mills, like the control unit, driving system, and feedback system, while others are specific to a certain type of machine. For example, tailstocks and headstocks are only found on CNC lathes. 1. Input Device.
