The Judgments of Ball Mill Grinding Task and the Finish Quality Level.

Grinding job status throughout the beneficiation process plant is well known in the selection of basic , significance. In the end what has been done grinding mill have such ease and position? VIPEAK said: grinding operations task is to bring the ore useful components completely or basically reached monomer separation , while also try to avoid over- grinding, sorting operations to provide appropriate ( size and mass fraction ) was selected pulp, in order to better recover useful components in the ore to create the conditions .

Second, determine the quality of the grinding operation is complete

Sorting index is good or bad depends largely on the quality of ground minerals . Therefore, they get ball between the major technical indicators are important . First grind minerals should granularity to meet different processing methods on the selected size requirements to ensure access to quality and useful minerals concentrate fully recovered . If the grinding fineness is not enough, various mineral particles are not reached full monomer separation , then the sorting index will not be too high ; but if too small mill to produce sludge , either mineral processing methods can not effectively recycled. If re-elected when the fine is less than 20.0 mm would be difficult to recover , while the lower limit for the effective recovery of flotation 5.0 ~ 10.0 mm, while excessive wear resulting sludge , pharmaceutical consumption will increase , loss of selective flotation process , even flotation will not be able to follow-up operations can also cause difficulties .

In the above case to meet , ball mill mineral sorting operation must also meet the required quality scores , the sorting operation has a range of suitable mass fraction , mass fraction too low are inappropriate. It should be noted , the best mineral grinding fineness and quality scores are determined through beneficiation tests .
