FM 306: SIZE REDUCTION AND SIEVING OBJECTIVE •To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving •To estimate the energy required for the grinding operation
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sinteringIt works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotati

Mills with size reduction media: Ball mills (dry) Ball mills are basically made of a drum partially filled with a grinding media, typically beads of ceramics or steel The mill is filled with the grinding beads as well as the product, then the mill is rotated until a speed ,
Method of installation of acoustic enclosure means that mantle the whole ball mill and add sound-absorbing body to eliminate reverberation noise inner the acoustic enclosure This method is usually available for 25-45dB noise reduction, but cannot effectively isolate ball mill noise to the outside world
The solution about the noise of ball mill 1Acoustic enclosure (soundproof hood) Use the acoustic enclosure to cover the whole ball mill, and then add a sound absorbing device in the hood to eliminate the reverberation noise This method usually gains the noise reduction of 25-45db (A), but it does not effectively isolate the ball mill .
