Dry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with a torque measurement. The influence of the ball size distribution on the specific selection function can be approached by laboratory runs using mono-size balls. The
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.

In powder grinding plant, ball grinding process flow includes crushing, milling,air classifying,packing,silos,bucket elevator,conveying,etc. Grinded material discharges from outlet grit fluently. Ball grinding mill is Formed a closed system with air classifier.
【Working principle of ball mill】 Ball Mills is a typical material grinder machine which widely used in the mineral processing plant, ball mill performs well in different material conditions either wet type grinding or dry type, and to grind the ores to a fine size. Main ball mill components: cylinder, motor drive, grinding medium, shaft.
With Attritor lab mills, users can choose wet or dry grinding, introduce inert atmospheres, operate at controlled temperatures, vary grinding speed, overcome product contamination, change media size and type, and get precise energy consumption information, all on the same lab mill.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
