capacity of sag mill and ball mill

What is the difference between a SAG mill and ball mill?

A SAG mill with a 44′ (134m) diameter and a power of 35 MW (47,000 HP) has been designed [9] Attrition between grinding balls and ore particles causes grinding of finer particles SAG mills are characterized by their large diameter and short length as compared to ball mills The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge SAG mills12102017· Ball mill is a fine grinder A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel The ball charge of a SAG mill is about 29% to 30% By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness The internal machinery of ball mill grinds the raw material into theDifference Between Sag Mill vs Ball Mill mech4study26112019· The internal machinery of the ball mill grinds the material into powder and continues to rotate if extremely high precision and precision is required Application The ball mill can be applied in the cement production plants, mineral processing plants and where the fine grinding of raw material is required From the volume, the ball mill divide into industrial ball mill and laboratory use the small ball mill, sample grinding test In addition, these millsWhat's the Difference Between SAG Mill and Ball Mill
