The grade and hardness of the ore supplied to the mill often vary considerably. In addition, equipment wear and drift will introduce uncertainty into the process management. This makes it difficult for a fixedspeed mill to operate efficiently and is one of the reasons why SAG mills and some ball mills utilize variablespeed drives (VSDs).
The comparison between single stage and double stage grinding has received much attention in the past few years. In order to submit information for use of mill operators, we have prepared comparative flowsheets for 50 Ton, 100 Ton, 200 Ton, 350 Ton and 550 Ton/24 hour plants, showing both single and twostage grinding in typical mill flowsheets.

Oct 12, 2017· Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
