WhatsApp: +86 18838072829SAG mills grind ore by lifting it and a small amount of grinding media and dropping it inside a horizontal mill. Ball mills are smaller and use a higher concentration of iron balls to pummel the ore. The mills can operate in an open grinding circuit, feeding secondary grinding systems, or in a closed circuit generating a fine product.
WhatsApp: +86 18838072829The Ball Mill, the Pebble Mill and the SAG Mill are 3 of the most popular types of mills on the industrial market.

WhatsApp: +86 18838072829Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. If a ball mill uses little or no water during grinding, it is a 'dry' mill.
WhatsApp: +86 18838072829A SAG mill of diameter m and width m was charged to 40% of the mill volume with ore of SG when the porosity was 38%.With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to the change in mill conditions.
WhatsApp: +86 18838072829In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 28%, so that the capacity of semi SAG mill to process materials can be increased by 1030%. The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation.
