Condition monitoring by a simple head-flow test near duty point using repeatable measurements has long been used but could be more widely adopted. An extension of this method can be used to calculate the best time to overhaul a pump based on balancing the cost of overhaul against the increasing energy consumption that occurs as a pump wears.

Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

[PDF]Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 0-30% pebbles, by volume, with savings in energy and ball consumption increasing progressively.

[PDF]When the proportion of pebbles in the mill charge was low (up to 30%), the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ball-mill to improve grinding efficiency.
