If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Ball Mill Parts. A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wear-resistant materials to prolong its lifespan.
From that "power draw" you calculate a shell size from 4 parameters: diameter, effective length, wet or dry? %loaded and % of critical speed. You also size an appropriate motor …

• Mill inspection via the inlet is possible, thus increasing personnel safety • Less wear and simpler form of wear lining on straight end walls • Short inlet cone • Less bearing clearance and thus less mill shell deflection polysius ® ball mill with direct drive There are two types of gear unit available for the mill drive unit.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill.
A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill …

The basic parts of the ball mill are a shell, balls, and motor Fig.2. A ball mill is also known as a pebble mill or tumbling mill. It consists of a hollow cylindrical shell (drum) containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The axis of the shell may be either horizontal or at a small ...
Loading the Mill. A cylindrical shell revolves around its axis to form the ball mill. Metal balls (or other grinding medium) are fed into the mill together with the components of black powder (potassium nitrate, charcoal, and sulfur) within the shell. Using a ball mill to make mixed black powder is a specific operation, but safety is crucial.

A ball mill's cylindrical shell is filled with large cylindrical pellets made of some material (typically stainless steel, or rubber). When the shell is rotated around its axis, the internal cascading effect of these balls and the material being ground within produces a fine powder.
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
The big gear of the ball mill fits on the mill shell, the size is bigger, the big gear is divided into half structure, the radial and axial run-out of the big gear are controlled within the national standard, the aging treatment is up to the standard, and the stress and deformation after processing are prevented. ... When connecting the main ...
The ratio of active mill shell surface area to ball charge surface area for the 5.0 meter (16½ foot) unit, is roughly half of that for the 2.4 meter (8 foot) unit. However, the actual ratios are so small (1 or 2 percent) that the amount of grinding at the shell is likely of little significance for either size.
