Similar to the ball mill work index, the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill work index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test.

The ball mill is classified as an intermediate and fine grinder where the action of the grinding is based on impact and attrition. The ball mill consists of a cylindrical shell slowly turning about
Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh …
Description. XMGQ work index ball mill is specially and mainly used to determine the work index of grinding of ores, slag, and other materials. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the industrial standards.
A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.

8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
Welcome to the most trusted and comprehensive Attrition Mills directory on the Internet. A broad range of Attrition Mills resources are compiled in this industrial portal which provides information on manufacturers, distributors and service companies in the Attrition Mills industry.
Some of the most common types include ball mills, pellet mills, hammer mills, and disk mills. Engineers and other professionals often refer to the process of grinding as a unit operation. This is a term used to describe a specific step in a process.
With Attritor lab mills, users can choose wet or dry grinding, introduce inert atmospheres, operate at controlled temperatures, vary grinding speed, overcome product contamination, change media size and type, and get precise energy consumption information, all on the same lab mill.
Bond Ball Mill Work Index, BWi, kWh/t 13.4 Bond Rod Mill Work Index, RWi, kWh/t 18.1 Table 1. Example of AG/SAG Ball Mill Circuit Wio Calculations [1] [2] ABstrAct Optimum use of power in grinding, both in terms of grinding efficiency and use of installed capital, can have
In this work, in order to look into attrition behavior ranging from fragmentation to abrasion, we have selected two different ball milling media: 25 mm Zirconia balls and 3 mm Zirconia balls, to generate different ball milling environments (harsh vs. soft).
See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Dec 23, 2013· Together with ball mill and jet mill, pin mill also acts by producing impact and attrition. Two discs with closely spaced pins rotate against one another at high speeds. Particles experience impaction with pins and attrition between pins …

As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals....
recirculation load for an attrition ball mill processing limestone with a bond work index of 10 and a feed particle size of ¼" x 0" is between 140 to 150%. The result is smaller hydroclones than for a typical horizontal ball mill system of similar capacity.
Attrition Mills from Munson Machinery are ideally suited for reducing fibrous and friable materials within a relatively narrow particle size range from coarse down to 100 mesh.
