Ball Mill Liner Design - Mineral Processing Metallurgy

05/01/2016  Liners furnished with heavy lifter bars are also sometimes used and in such a case the locking of the ball charge to the shell must be very effective. Nevertheless, although a few vague general statements to the effect that a lifter mill gives a product with different size characteristics to that of a smooth mill

Analysis of power draw in ball mills by the discrete ...

01/04/1999  This is a unique feature of this numerical technique, because none of the existing models for power draw is capable of accounting for the lifter dimensions or the number of lifters or even the ball size distribution. The design of lifter-bars should be such that the mill is able to draw adequate power to achieve maximum throughput and at the same time, minimize liner damage. All the ...

Semi-autogenous grinding (SAG) mill liner design and ...

Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (e.g., a 34-ft-diameter mill shell would have 68 shell lifters). This is also called a 2-D shell lining. Eliminating some shell lifters increases the volume of charge between the lifters

Mill Lifters. The number of lifters generally can be determined by the rule-of-thumb: Number of Lifters = 3nD for double wave liners = 6.6D for single wave liners where D is the mill diameter (m). Double wave liners are more suitable for ball sizes less than 60 mm. Otherwise, single wave is preferred. Grinding Media. The bulk densities of the steel media typically used are: Balls 4650 kg/m 3 ...

01/08/2001  The ‘standard’ ball mill used throughout this study has an internal shell diameter of 5 m. There are 23 lifter bars spaced circumferentially around the mill shell. The standard lifter is symmetric with an 85° face angle and is 210 mm wide at the top and has a height of 200 mm above the liner. The wear plates between the lifters protect the ...

The Selection and Design of Mill Liners - MillTraj

even mill shell damage arising from impacting of the charge directly on the liner, and unsuitable spacing of lifter bars yielding unfavourable compromises between lifter bar height and liner life - have highlighted the significance of correct mill liner selection. Liners protect the mill shell from wear and transfer energy to the grinding charge, and a careful balance is required to optimise ...

The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size. Considering a typical mining operation processes 10,000 to 100,000 tons per day the energy expenditure in grinding is 50 percent of the cost of production of the metal. A research team from
