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. •To analyze the results using the available theories. INTRODUCTION
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiralshaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill .
Ball Mill and Grinding Circuit Preparation for StartUP The following items must be checked before the equipment in the Grinding Circuit is started. Check the ore slot feeder for obstruction or hang—ups. Check the ball mill belt feeder for undue buildup of material. Check oil level in ball mill lube oil tanks. Also, check grease level in the mill ring gear spray lube drum.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.
Ball mills Ball mills are used for dry and wet grinding of different materials such as cement materials, cement, lime, and ceramic materials.
