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, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.

grinding) has a step lining suitable for large grinding media. It protects the shell while ensuring optimum lifting of the mill charge.

feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and

maintenance" (Shoemaker and Gould, Modern Mill Design, 1980). Again to quote Shoemaker and Gould, "Increased production of the final product is often more easily and economically attained through expansion than by increased recovery." Planning for expansion is therefore a consideration in all but the shortest-lived operations. Even at mines

Fast, easy installation A vertical roller mill capacity upgrade can be achieved without significant changes to existing machinery, so there's very little downtime during installation. Downtime can be further minimised by installing the upgrade during a planned maintenance stop. Typically, it takes only a few days to connect the HRP to the mill.

Three-piece "compression-type" liner bolt sealer is designed to prevent leakage of slurry. or dust from mill liner bolt holes. Used in conjunction with Grade 5 (high-strength) bolts, this assembly is generally applied to rod mills over 10.0′ in diameter and ball and. autogenous mills greater than 13.5″ in diameter.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

Like a ball mill, the grinding media size in a Tower mill is dictated by the top size of the feed andproduct­ Steelballsizes in the Towermill are limited, however, to a maximum of 32 mm (1.25 in.). For very fine grinds, balls as small as 6.4 mm (0.25 in.) are used. Since steel grinding balls weigh approximately 4646 kg/m!

the trend in large SAG mills has been to use wide-spaced shell lifters with large lifter face angles, primarily to reduce packing and ball/liner damage, and to use larger, hence fewer, mill liner parts to reduce downtime at liner change-outs.
