The rod mill work index values in this survey were based on results from Amdel which is believed to have used a non-standard rod mill using a smooth liner. Bond rod mill work index determinations are supposed to be done in a mill employing a wave liner.
The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus. The SAGMILLING models …
• The Bond Ball Mill Grindability Test determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills. The test is a closed-circuit, dry grindability test. It is run in a standard ball mill and can be performed at mesh sizes ranging from 48 mesh to 400 mesh. Bond Ball Mill Work Index (and modified ...
One complication to comparing parameters is a difference in the apparatus used at some laboratories for the rod mill work index. The apparatus specified by Bond is that the rod mill should have a wave …
Issues with a smooth liner A "Bond" rod mill work index is to be determined in an apparatus with a wave liner. The author is aware of four laboratories that offer a rod mill work index test where the lining of the mill is either smooth, or smooth with a small number of primitive lifters that do not constitute a wave liner (one of
Rod mill on working site. 1 The rod mill usually uses a steel rod with a diameter of 50-100 mm as a grinding medium. The length of the steel rod is 25-50 mm shorter than that of the cylinder, and is usually made of high …
The standard bond rod mill work index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample.the test then involves a series of batch grinds in a standard bond rod mill.a bond rod mill is 0.305m by 0.610m, with wave liners (of a form described by bond), which runs at 40rpm and tilts as described below.
The Titan Bond Work Index Rod Mill is one-piece cast construction with integral wave liners of a form described by Bond. This mill is used to perform the necessary metallurgical testing to determine the grinding …

Rod mill liners are subjected to severe impact. Premature breakage and scrap loss are reduced by correct selection of liners for the specific grinding duty. Additional benefit results from use of a backing …
Rubber liners absorb the impact of the larger grinding media and thus protecting – the mill structure and prolonging it's life. Weight: Rubber weighs about 15% of an equivalent volume of steel. This means …
Of the many types in use, the cylindrical mill, which employs a cascading mass of balls or rods, is universally used for the size reduction of hard, moderate to highly abrasive materials, such as minerals, ores, stone, …
wave liner bond rod mill Customer Cases Glass Reinforced Plastic Structural Armor liners within the M113 and Bradley Fighting Vehicles; most recently S2 glass-reinforced plastics have been accepted for liner applications.
When converting a mill from steel to rubber liners, the design must be changed from such familiar steel liner shapes as wedge bars and plates, wave liners, and ship-lap to take advantage of the ...

They require a specific 305mm diameter x 305mm long (inside dimensions) horizontal axis ball mill without lifters operating at 70 rpm to perform grindabilities from 28 to 500 mesh and a 305mm diameter x 610mm long …
describes both the breakage energy consumed and the size distribution of the mill product. The action of a wave liner in a rod mill is to lift the mill charge and …
The use of a rod mill for producing manufactured sand is not a recent application. A Marcy Open End Rod Mill has been operating at the plant of the Sun Sand Company, Thayer, West ia, since 1925. In early 1940 an. 8' x 12' rod mill of the open end type was installed at Shasta. Dam, near Redding, California for sand production.
Bond Test WI's (kWh/t): Rod Mill: Ball Mill: 9.5 kWh/t.8 9 kWh/t . Bond Standard Circuit Work Index: Assume the rod mill Work Index of 9.5 applies from the actual rod mill feed sizeof 19,300 mµ (although some of this work might ideally be done by crushers to achieve a rod mill F80 of 16,000 m) to a rod µ mill (circuit) product size of 1,000 ...
empirical calibration between the two styles of mill liner. Bailey et al. (2009) described a rod mill work index round-robin program between different international laboratories with a normalized standard deviation of 12%. It is believed that the round-robin is a mixture of smooth and wave liner designs. The Author is aware of three Australian
Hence in this particular example, rather than rod mill tests being carried out, tests suitable for crushers, AG/SAG mill s and HPGRs should have been substituted. ... Bond rod mill . Rod mills ...
Assist the lift of the media and ore to the desired height in the mill. Liners can be made of manganese steel, Ni hard or high carbon steel and hard rubber or synthetic material that is 65 – 75 mm thick. The liners can be: …
Essa's ball and rod mills can be supplied as complying machines with the appropriate barrels and ball or rod charges. As with our standard range of ball and rod mills, the Essa® Bond Index Ball Mill and Bond Index Rod …
