RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each appliion. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming

Experimental ProcedureExperimental Procedure Where nc = Critical speed (rpm) R = Radius of the mill (m) r = Radius of the ball (m) Critical Speed Observation Radius of the mill = 0.85 m Radius of the ball = 0.025 m nc = 33 rpm So operating speed = 25 rpm All basic parameters have been calculated while considering existing experiments in ball

The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by

2012710&ensp·&enspThe design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this

2020515&ensp·&enspSee 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. The sample was received crushed appropriately for the ball mill test.

With a view to developing a sound basis for the design and scaleup of ball mills, a large amount of data available in the literature were analyzed for variation of the two key mill performance parameters: power specific values of the 'absolute breakage rate of the coarsest size fraction', S *, and 'absolute rate of production of fines', F *, with some of the important operating and

According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 3.327 mm.
