Practical 1 Ball Milling

23-12-2013In 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
