Continuous Rod and Ball Mill Sepor, Inc

Sepors 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill. The spiral classifier is popular in pilot plant grinding due to the ease in which the oversize is returned to the

grinding mill initial charge ball mill odanahschool

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.
