material retention time in a ball mill vrm page 1 of 1 Aug 11 2010 Re MATERIAL RETENTION TIME IN A BALL MILL VRM You could do that by measuring the material flowrate Qtonsh through the mill as well as the quantity Mtons of material that accumulates

Motor HP and Production is totally depends on material and fineness. All the data given are nominal only. It may vary widely from case to case depending upon many factors. We also offer other based on customer request. Use of Batch Type Ball mill: Batch Type Ball Mill is useful for grinding coarse feed to get fine wet or dry powder in single continuous operation.

Therefore, a mill with a fine ball charge cannot handle a high mill throughput without operational problems. Tests carried out at the Lafarge Plant in St. Constant in Canada, utilizing the same mill with two different ball charges, have shown that for an equal throughput the finer ball charge had the higher retention time.

OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently reactive to

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different

Therefore, ball abrasion rate in the mill determined by Equation 10. A𝑟= At F =4003321.8 131328 =30.48 g/ton (10) In above equations: 𝑣m: 3total mill volume (m ), 𝑁: number of balls which exist in mill, 𝐴𝑏: each ball abrasion (g), 𝐴t: total ball abrasion in the b3

The pulp should have a volume of *25%= in the ball mill. Then the minimum grinding time = /= Note: When the grinding time is the shortest grinding time, it is ideal when the large block is directly ground to the granule size, and there is no overgrinding phenomenon.

The grinding process for all the three iron ores is carried out individually in Bond's ball mill and the total retention time taken by each iron ore sample is calculated. The present investigation focuses on utilizing the calculated retention time of the iron ore as a standard grinding reference time to the laboratory ball mill for optimizing the grinding time of each ore.
