A Laboratory Ball Mill is used for grinding in laboratory flotation test work, wet grinding is necessary in several stages in order to approximate the actual grinding conditions of a ball mill and classifier in plant operation. With this small ball mill it is possible to grind successfully in several stages without dilution, because the large feed opening and discharge hole (which retains the balls while the mill is being discharged) permits quick and thorough draining with the use of a minimum of wash water. Used in conjunction with a (Closed) Ball Mill, and a laboratory batch classifier saves time.
Batch Laboratory Ball Mill
The (Open) Batch Mill makes possible simulation of grinding in a ball mill-classifier circuit by grinding a fixed time, then hand classifying with a sieve and a bucket and returning the sand to the mill for further grinding. Pulp volume can be kept at a minimum by control of wash water since the ball load does not ….Read more
