In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level See also crusher for mechanisms producing larger particles In general grinding processes require a relatively large amount of energy for this reason an experimental method to measure the energy used locally during milling with different machines was recently proposed
WhatsApp
The operating principle of the ball mill consists of following steps In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls
WhatsApp
Ball milling is one of the few unit operation that improves with increasing mill diameter If acceptable results can be obtained with a 12" jar mil then good result will certainly be obtained with a 72" diameter mill
WhatsApp
The collision of spherical medium is point contact during grinding so the ball milling efficiency is high and it is easy to grind fine but compared with rod grinding the phenomenon of over grinding is serious When the grain size of ore feeding is below 30mm and the particle size of grinding product is less than 1mm the rod grinding efficiency is higher
WhatsApp
Another important task associated with the ball mill grinding operation is to establish a sound basis for carrying out scaleup of ball mills based on laboratory or pilot scale test work This requires studies related to the influence of mill diameter on production rate of particles of a desired size distribution
WhatsApp
Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical mechanical and chemical characteristics Typical examples are the various ores
