The discharge system of a mill is the most complex and time-consuming part of the mill to reline. The new Megaliner™ for discharge systems integrates dischargers, grates, lifter bars and filling segments in one unit, reducing the number of components used by as much as up to 70%. This can cut your installation time in half.
Typically in wet overflow grinding mills the product is allowed to exit the mill by overflowing the discharge trunnion. The driving force for flow of slurry from the feed to discharge end of the mill is the flow gradient due to the discharge trunnion being larger than the feed trunnion. However, grate discharge mills have a more complex mechanism.
