Mar 21, 2007 Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity or mill throughput of AG and SAG grinding mills. Generally, the discharge from AGSAG mills consists of one or both of the following components slurry water and finer particles and pebbles 20-100 mm.
Grinding mills - CM50 C25 The grinding disc mill CM 50 was developed for grinding of apples and pears. In the meantime it is successfully used for the milling of various other fruits and vegetables such as cherries, strawberries, black currants, carrots, onions etc. The CM 50 mill produces mash structure which is ideally suited for dejuicing.
All mineral grinding mills suffer high wear rates of their internal components. All cylindrical tumbling mills AG, SAG, Ball and Rod Mills feature cylindrical structural shells, protected from abrasion by removable, replaceable mill liners. Every tonne of mineral ore must be processed through the grinding mills.

Jun 02, 2017 Autogenous grinding AG and semi-autogenous grinding SAG mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
