Condition Monitoring of Ball Mill with HD Technologies
In a ball mill, steel or stone balls are mixed with the ore and during rotation of the drum the ore is ground, by friction and compression, into a suitable fineness for the next step in the process. The main component of all mills is a rotating drum, turning with a suitable speed, gearbox, and motor. The mill is a very important part of the milling process in the cement industry. In many cases

Practical 1 : Ball Milling | TF Lab 1
In roller mills, the principle of attrition is used where material is sheared as it passes through a gap and is transferred from slower roll to a faster roll, and is removed by a scraper. In ball mill, size reduction is done by both impact and attrition of particles. Rod mill is similar to ball mills but it uses long rods for grinding media
