Mar 15, 2016 Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding medium and the mills were lined with either silex

Capacity. 1-95t/h. Input size. <25mm. Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.
The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well. To help the process along, eight-inch-diameter steel balls are added to the rocks as they tumble
Jan 01, 2016 To grind the ore to the liberation size the mill was run at 72% of the critical speed when charged with balls 64 mm in size and 7.9 t/m 3 density. Determine: 1. the fraction of the mill filled with balls, 2. the mass of balls charged. 7.9. The feed size to a single stage wet ball mill was 9.5 mm of which 80% passed through a 810 μm sieve.
