• OSTI.GOV Technical Report: Optimization of Comminution

Jul 01, 2005 Abstract. The goal of this project was to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process were used to study methods for optimizing the product size distribution, so that the amount of excessively fine material produced could be minimized.

throughput is often not achieved. This decrease in grinding efficiency, coupled with increasing mill size, suggests two possible problem areas: 1. There is a size limit to mills, beyond which increasing size is detrimental to efficient use of energy. 2. The correlations which relate the power needed for a specified

Unlike most types of mills, cone mills can be used for hard to grind products while using less energy than other types of mills. Cone mills are preferred in some industries because they produce less noise, dust, and heat than traditional milling equipment. Equipment Design Material is fed into the conical chamber by gravity or conveying it.

cement production is for material size reduction. Increasing the efficiency of particle size reduction could have a large impact on energy consumption in the cement industry. Current estimates of grinding power requirements used for equipment sizing are indirect indications often based on industrial experience or scaled up from laboratory tests.

Furthermore, the fine grinding costs increase exponentially with decreasing product particle size. As a result of the increased energy requirement for fine grinding, it is desirable to optimise fine grinding processes such as stirred media milling (ie IsaMill) to enhance energy efficiency, throughput and the product fineness.

• More efficient grinding for Iron Range industries

Jun 03, 2020 Traditional taconite pellet-making processes use a rod mill to get the rock to the consistency of coarse sand, and a ball mill to grind the rock into a fine powder. This technology is still in use on Minnesota’s Iron Range by some facilities. A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 pounds.
