Autogenous tumbling mill, also known as media-free grinding machine, can directly process raw ore from the quarry or ore that has been coarsely crushed. The biggest feature of the autogenous mill is the large crushing ratio. The feed size of AG mill can reach 300~400mm or even larger, while the minimum discharge size can reach 0.1mm, and the crushing ratio can reach 3000~4000. In comparison, the feed size of ball mill is usually between 20-30mm, while the product size is between 0-3mm.
The wet autogenous grinding system is composed of wet autogenous mill, particle size control operation, secondary grinding equipment and processing facilities for difficult-to-grind particle grades. Usually the minerals are fed into the mill rod mill according to a certain size ratio. The autogenous mill can grind the material to 0.074mm at one time, and its content accounts for more than 20% to 50% of the total product. The crushing ratio can reach 4000-5000, more than ten times higher than that of ball and rod mills.
Autogenous mill is a new type of ore grinding equipment with both crushing and grinding functions. It uses the material itself as the medium to achieve crushing through mutual impact and grinding. The autogenous mill has two driving modes: variable speed and fixed speed with different power, and some autogenous mills are also equipped with micro-motion devices. It is equipped with a cylinder jacking device for easy maintenance; for large mills, in order to eliminate the static resistance moment when starting, modern advanced technologies such as hydrostatic bearings are used to ensure the safe operation of the autogenous mill.
