are the Bond Work Index (Wi) values (Bond, 1952), divided into a low energy crushing work index (Wi C) for coarse rocks (75-50 mm), a rod mill work index (Wi RM) for intermediate sized particles (25-3 mm), and a ball mill work index (Wi BM) for small particles (<3 mm) (Ammtec, 2000). Laboratory

range. This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm). Rittinger's law showed more _app1icability to the fine

The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to passing size of <3.35 mm.

XMGQΦ305 Grinding Bond Ball (Rod) Mill is mainly applied for testing the grinding work index of the material of every kinds of ores, slag, etc. Under the specific rotation speed for dry grinding, then screening the products, weighing, repeat operation several times, getting the grinding work index kWh/t

GRINDING LAWS The three laws of Rittinger, Kick and Bond can all be derived from the follow- ing relationship, proposed by Charles (1957), between energy consumed and mate- rial size C.51 : &=-kg Yn Setting the exponent n to 1, 11 or 2 upon integration defines the …

size reduction circuits (Charles, 1957). However Bond's Third Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond's theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond's equation is as ...

Bond crushing law. A. Calls for relatively less energy for the smaller product particles, than does the Rittinger law B. Is less realistic in estimating the power requirements of commercial crushers. C. States that the work required to form particle of any size from very large feed is proportional to the square root of the volume to surface ratio of the product

The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...

As with Bond's third theory of comminution, the SP1 energy relationship is based on a "standard" circuit. Essentially the SP1 energy relationship does for SAG/AG circuits what Bond's third theory does for ball mill circuits (where pebble crushing is never done). Predicting the milling swings.
