In comparison to conventional tumbling mills, i.e., rod and ball mills, the grinding media in an autogenous mill derive from the feed ore itself Rowland and Kjos, 1978.Any change in feed ore properties will therefore affect the grinding charge and thus, the breakage mechanisms within the mill.

Ball Mills. Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft x 8 ft with 75 HP to 30' x 41' and as much as 30,000 HP Larger ball mills are available with dual pinion or ring motor driv Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
We offer a full line of parts for rod, ball, and semi-autogenous grinding mills for cement plants. Shell liners We offer many choices in design and alloys for all popular mills, ranging from traditional wave styles to step liners, classifying liners and SAG mill liners.
Application of SAG Mill Liner. Our SAG Mill Liner are widely used in the grinding stage for mining industry, cement industry, thermal power plant, paper-making and chemical industry etc. Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening.
Thus it offers a savings in capital and operating costs. 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.
Jul 15, 2019· Motors are rated as one of four "design types" for their ability to endure the heat of that starting and pull up. In ascending order of their ability to start inertial loads, NEMA designates these as design type A, B, C, and D. Type B is the industry standard and is a good choice for most commercial and industrial applications.

Apr 01, 2016· If one looks back over the last 70 years or so there is a fairly common theme to most of tumbling mill power draw models (Bond, 1961, Hogg and Fuerstenau, 1972, Arbiter and Harris, 1982, Austin, 1990).This is that the models used the charge shape shown in Fig. 1 in which it was assumed that all particles moved with same rotational rate and that the slurry phase was not explicitly considered.
Special Options. All models can be equipped with a torque meter to precisely measure energy expended in the grinding chamber. Stationary arms can optionally be fitted into the tank wall in configurations best suited for your specific application.
The price of a motor depends on the rated torque of the motor (more-so than the motor rated power and diameter), so for large mills a slight increase of the motor rated speed can result in substantial price savings. Operating at higher mill speeds can reduce operating costs by permitting operation at lower ball charges for a given mill power draw.
ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.
