Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ...
Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
HIGHLIGHTS OF AGICO GOLD BALL MILL. The grinding fineness and grinding time can be adjusted automatically. The cylinder body is welded by steel plates with a thickness of 1536mm. Grease is used for main bearing lubrication to avoid heavy metal pollution. The gold ball mill has the advantages of small vibration, low noise, and low labor intensity.
Ball mills generally have a length to diameter ratio in the range of to An economic form of grinding used in many newer and higher production plants is the autogenous grinding mill. In this mill, the rock is allowed to crush against itself as it cascades in the mill, thus saving the cost of replacing steel balls as they become worn down.
