Size reduction techniques. The four basic techniques used in size reduction of dry powders are impact shear attrition and compression forces. In some cases a combination of these may be found in a single mill type. Impact and attrition size-reduction methods include air classifying mills pin mills hammer mills and jet mills.
Steel Ball Mills amp; Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.

The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous SAG Mill via an utilized method. Miduk copper concentrator is located in Kerman Province Iran and its size reduction stage includes one gyratory crusher which feeds one SAG mill 9.75 dia.m3.88 lengthm following two parallel ball mills 5dia.m7lenghtm.
The ball mill is then sealed and rolled for a period of time sufficient to reduce the particle size of the pigment to less than about one micron. Generally about 2 to 24 hours is sufficient although longer times may be used. The time of agitation is not critical so long as the time is sufficient to achieve the desired particle-size reduction.
The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3. 2.2 Sample preparation The copper-cobalt ore used in
