The compact spiral lining is mostly used in mono-chamber mills, or mills with a long second grinding compartment. The large number of progressive activator plates means that the ball load is moved optimally. The plow plates increase the energy transfer once again, creating a certain moderate sorting effect for the grinding balls, which improves the grinding power inside the ball charge.
