Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and :1.
Ball Mill Work Index tests using crushed feed, and Standard Autogenous Grinding Design (SAGDesign) Tests, patented by Outokumpu. (See reference 8 below). The comparison of these results gives context to how the various measurements relate to each other and how they can be used to obtain an accurate design for the grinding mills required for

A Bond Ball Mill Work Index test is a standard test for determining the ball mill index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006). This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required
Milling – Rod / Ball Mills including Bond Ball Work / Grindability Index MARC manufactures a wide range of ball and rod mills to suit most metallurgical laboratory applications. Our range extends from small 6L jartype mills that are manually positioned on rollers to large 30L size mills.
The Bond ball mill work index is one of the most commonly used grindability tests in mining and is often referred to as the Bond work index.. The test is a lockedcycle test where ground product is removed from test cycles and replaced by fresh feed.
Similarly to Bond Work Index, k parameter considers, besides the energy consumption, the sizes from mills feed and product which normalizes the data from the three mills. 0,0 2,0 4,0 6,0 8,0 10,0 12,0 14,0 t Ball mill 1 Ball mill 2 Vertical mill Average ball mill 1 Average ball mill 2 Average vertical mill
