The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.Web

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.Web

Overview of Ball Mill. Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylinder-containing balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.Web

Working of Ball Mill. The ball mill works by introducing the material to be ground into the feed hopper. The material is then pulled into the mill by the rotation of the drum. As the drum rotates, the balls inside the drum strike the particles, breaking them down into smaller pieces. The ground material is then discharged through the discharge ...Web
