cement manufacturing

The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement Commonly used separators are in closed circuit grinding are O –sepa Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm)

Ball Mill

Ball mills are used primary for single stage fine grinding regrinding and as the second stage in two stage grinding circuits According to the need of customers ball mill can be either wet or dry designs Ball mills have been designed in standard sizes of the final products between 0 074 mm and 0 4 mm in diameter

Mill Bolting

The mill manufacturer specifies a load which is designed to be the optimum load applied to the bolts to hold the mill together for its entire life which can be in excess of 20 years some mill manufacturers specify an elongation unfortunately they usually specify a torque figure which should in a best case produce the correct elongation but rarely does

5 Questions to Ask Before Selecting an End Mill

The length of cut needed for any end mill should be dictated by the longest contact length during an operation This should be only as long as needed and no longer Selecting the shortest tool possible will result in minimized overhang a more rigid setup and reduced chatter As a rule of thumb if an application calls for cutting at a depth greater than 5x the tool diameter it may be
