The mill is not a pressure vessel and there is no need for shaft seals. Gravity keeps the grinding media in the mill and no external screens are needed. The unique mill construction guarantees optimal grinding conditions in the whole mill volume.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
The material is charged into the mill at the top and is discharged out the bottom side, making use of centrifugal force. The HSA is used when smaller particle size (generally 40 mesh) materials are fed into the machine and micron size end product is desired. ... • Stainless steel grinding chamber • High speed, high volume production ...
a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grind-out is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop.

Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length. The ore charge is usually 25 to 35% of the mill volume.Autogenous mills have grate discharges to retain the coarse grinding media in the mill.
A grinding mill power model that is a function of load behaviour parameters was previously calibrated against data collected on an industrial autogenous mill.
