An indirect consequence of this analysis is the observation that Bond‘s approach based on feed and product D80 passing sizes is probably a good estimate for grinding power consumption only in the particular cases For example when a rod mill is operated in open circuit or a ball mill is operated in closed circuit with classifier under normal conditions of circulating load in which the
P Product size 80 passing µm F Feed size 80 passing µm fx j 0295x j1000000 In 2011 Morrell discussed the appropriateness of SAG mill transfer size in regards to grinding mill specific energy modelling It was suggested that since AGSAG mills are mostly operated in very near 274 Get Price VertimillOnline Chat
First a Jar Mill grindability test requires a 5 lb 2 kg sample and produces a direct measured specific energy net Hphrt to grind from the design feed size to the required product size The second test a Bond Work Index determination results in a specific energy value net Hphrt from an empirical formulaOnline Chat
The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 14 to 16 Rod mills accept feed up to about 50 mm 2 in and produce a product in the size range of 3000 to 270 mm –4 to –35 meshOnline Chat
Complete size range to fit your grinding needs The OK Mill is offered in a complete size range including 3 4 and 6roller mills and the largest vertical roller mill size available with installed power over 11 500 kilowatts This ensures the ability to meet all possible capacity requirements in a single vertical roller mill solutionOnline Chat
Jan 01 2016 · As a result of the crushing operation a spread of smaller product size is obtained and fed to the grinding mill To use Equation 33 therefore Bond considered the work as the energy required for the reduction of feed particles that passed 80 of a particular sieve to a product particle size that passed 80 of a sieve openingOnline Chat
mill equipment size but also dictates how to operate the mill whether continuous or batch operation is required and whether the process can be performed inhouse or if a tolling service is a better option The required product size is an important grinding cost factor especially for finesize grindingOnline Chat
