Worldwide awareness of environmental issues mandates regulatory measures which establish strict ambient air quality standards to control emission levels. For decades, many countries have been devastated by uncontrolled emissions of pollutants. The ecological balance has been damaged to the point that stringent steps must be taken to control pollutant emissions. As a result, various national and regional agreements have reduced acceptable pollutant emission levels. Highly industrialized countries with densely populated regions suffering from high levels of pollution have established the most rigid emission standards.
Ball Mill Bond Work Index for Limestone
Ball Mill sizing is based upon tonnage, feed size, product size, operating or test plant data or the Bond Work Index Method. The Bond Work Index indicates a relative grindability of the limestone. The Work Index number is developed by grinding a small sample of the material in a laboratory unit using a defined procedure.Additional consideration must be given to the
amount of the circulating load (recycle) and its effect on grinding system performance and power requirements. Typically, circulating load will range between 300% and 500% depending on feed size, limestone hardness, mill characteristics, ball size, etc.
Grinding Wet Ball Mill Limestone
Wet grinding is usually preferred over dry grinding. When looking at the grinding process in isolation, there are pros and
cons of wet versus dry. Dry grinding requires more power, yet has less ball and liner consumption that in wet grinding. Additionally, the capacity of a dry mill is typically less per unit mill volume than it is with wet milling.Size ranges described in this manner are variable in practice and can have occasional 1 to 3” tramp material and or higher percentages of fines. The horizontal ball mill is capable of accepting this stone size direct, without any pre-crushing function, thus improving system flexibility, simplicity and reliability. Abrasion is controlled with wear resistant mill liners and by the inherent concentration of the wear in the media.
