AMIT 135: Lesson 7 Ball Mills & Circuits
Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, …

Ball Charge Design and Management | Stone Crusher
1) Grinding transfers energy from a mill's motors to particles through the movement of balls within the mill. 2) The size of particles being ground, type of grinding (crushing or attrition), ball size, and mill speed determine the specific energy required. 3) An optimized ball charge has a mixture of ball sizes to match the material being ground, high porosity for particle retention, and a

8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the particles of media - the rods, balls or pebbles. This motion can be characterized as collision …

Introduction The closed ball milling circuit is a key part of many minerals processing operations. Recirculating load is the fraction of mass flowing through the mill divided by the feed throughput, and this has been found to be a significant consideration in mill circuit performance, and thus the economics of the operation. This paper will describe a digital tool and methodology that can
