Nov 16, in the laboratory, the common method to be used as the ball mill. this work aims to design a simple horizontal ball mill. calcium carbonate material from limestone and eggshells powder was ground using the developed ball mill. the balls to powder ratio (bpr) and powder type were investigated in relation to the particle.
The ball mill contains a hollow cylindrical shell that rotates about its axis. this cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it. ball mills are classified as attritor, horizontal, planetary, high energy, or shaker. view chapter purchase.
The ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 1–1.5 times the shell diameter ( figure 8.11 ). the feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by.
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting ma terial (feeders), and the system for discharging the output.
