2) Usually the mechanical squareness measurement are made on 250-300 mm so the value that you say, 2 cent, is the same value that you obtained with Ballbar (-0,061 mm/m=>0,020 mm/300). Usually the sag compensation table is used to compensate the horizontal spindle bending due to the weight of the spindle.

Because it has a great weight on it, when it is stopped, the oil is squeezed out from between the inner and outer bearing. Before the mill is started up this bearing must have oil injected into it by way of a pump. The pump must be started before the mill begins to turn and must continue until the mill has made at least one revolution.

an existing SABC (SAG mill with recycle crushing and a single stage ball mill). First, a pre-crush stage using HPGR was introduced to minimise the generation of critical size material in the primary mill. The aim was to reduce a portion of the feed material below critical size and generate more fines to decrease the load in the primary mill.

Safe and speedy replacement. Thinner mill liners result in a larger volume inside the mill. This means you can have a higher charge level. Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.
