Book excerpt: On going research at the University of Alabama has shown that stirred ball mill grinding is the highest cost unit operation in the beneficiation of Eastern Oil Shales. Minimization of that cost is critical if oils derived by beneficiation and hydroretorting of Eastern shales are to become an economic alternative to conventional crude oils. Cost optimization of stirred ball milling is a substantially different problem than optimizing a conventional (tumbling) mill operation. For conventional mills minimum cost is virtually synonymous with minimum energy consumption. Because the technology is mature and well understood, the operator can predictably optimize within a very narrow range of operating conditions. In contrast, stirred ball milling offers the operator several more ''degrees of freedom'' in selecting operating conditions. An example is the selection of rotor speed. In general, lower speeds result in lower energy consumption per ton of material ground but at the cost of reduced mill capacity per unit volume. Because stirred ball mills have a high capital cost per unit volume the trade off between energy consumption and capacity becomes critical. This paper presents a generalized total cost mode for stirred ball milling and examines data generated in the grinding of oil shales in terms of the model. The paper also discuss the role of the cost model in guiding future research in grinding circuit optimization.

Available in PDF, EPUB and Kindle. Book excerpt: A 5-litre vertical batch stirred ball mill was used to study comminution characteristics. Chromite sand was used as the feed. A factorial design was prepared with the following parameters, which influence grinding in a stirred ball mill: pulp density, pin-tip velocity, ball density, and size. The energy required for grinding the chromite sand in the stirred ball mill was determined by the use of Charles' Equation. The findings are in agreement with the results predicted by this equation. It is shown that the Rosin-Rammler size distribution equation fitted the data over a wide range of operating conditions. For any particular grinding condition, it is possible to use only the size modulus, since the Rosin-Rammler lines are parallel. The relationship between the selected function and the Charles' energy-size relationship is demonstrated. The link to Bond's law is also discussed and it is concluded that Bond's law does not apply to this grinding regime. The factors that have the greatest effect on grindability are, in order of importance: ball size, pin-tip velocity, and ball density. Interactions between the grinding parameters are negligible. The results imply that accurate predictions can be made to determine the grinding conditions required to achieve a desired product specification.

This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were made of the grinding kinetics of chromite ore in a stirred ball mill. Grinding tests were carried out using material in discrete size ranges (-53 + 38 micrometers and -38 + 25 micrometers) and for material conforming to a natural spread of sizes (-100 micrometers). Tests conducted on the discretely sized material were used to establish the breakage function for the ore. Specific selection function parameters were established by milling the -100 micrometers material for various inputs of energy. The population-balance model derived from the test results yielded good agreement between the measured and fitted product size distributions. A relationship was established between the specific selection function and the pin tip velocity, ball density and ball size.

Book excerpt: "The study of the ball mill is very complicated, due to the varying conditions existing in the mill. Some of these conditions are: Size of grinding media, size of feed, moisture content, and speed with its effect on the paths of the grinding media. A brief history of fine grinding will first be outlines, after which some of the theories of ball milling will be stated. Then the paths of the grinding media will be given some attention, and a new point of view about the trajectory will be brought out"--Introduction, leaf 2.

Available in PDF, EPUB and Kindle. Book excerpt: 2Vlanuals of mineral dressing or more precisely those of comminution-classifi cation treat in particular the mechanics of the machines, and generally their handling. In this way the plant engineer becomes acquainted with the equip ment but is given no help in learning something of the processes taking place in the material to be comminuted even though the purpose of the operation is to enhance wanted and to avoid unwanted physical or physico-chemical processes. Neglecting the description or representation of generally used and well known equipment the object of this monograph is to supply information on the processes taking place in grinding installations. It explains the sometimes complicated phemonena by applying quite simple means; it requires only an elementary knowledge of mathematics, mechanics and physical chemistry. The ideas are applicable to the grinding of all brittle raw materials or semi finished industrial products. The special problems of cement grinding and thm;e of hall mills are explained in more detail; in cement grinding we have to meet special requirements with regard to ball mills apart from other con siderations -, since these now demand the greatest overall energy consumption. Currently disputed problems are dealt with, and naturally the views of the author are given in detail, but contrary views are also mentioned and the ample list of references ensures that these opposing views can be considered.
