Live Chat### The energy efficiency of ball milling in comminution

The surface area, size distribution and specific energy consumption for the material ground in the ball mill were used in conjunction with the single particle data to provide an assessment of the energy efficiency of ball milling. In addition, using the extensive published results on the comminution of quartz, this paper provides an attempt to tie together the range of information in the

Live Chat### Factors Affecting Ball Mill 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 length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for

Live Chat### Grinding in Ball Mills: Modeling and Process Control

The 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 ratio most frequently varies from 0.5 to 3.5. The starting material can be loaded either through a spout feeder or by

A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a

To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as possible. Thus as small balls as possible should be used in each stage. Difference Between Ball Mill and Rod Mill. Rod Mills. The principal field of rod mill usage is the preparation of products in the 5 mm0.4 mm (4 mesh to 35 mesh) range. It may sometimes be recommended
