We offer AEROFALL mills as autogenous or semiautogenous mills for drying and grinding. A large diameter to length ratio is characteristic for these mills. The feed material can have a lump size of up to 500 mm. One fundamental advantage of this mill is that it even accepts sticky materials that have moisture contents of up.

The process known as comminution is the breakdown of ores to freely liberate the gold or other valuable minerals from their host matrix or gangue, to be recovered through a gravity-based system or any other recovery media that requires the gold or valuable mineral to be mostly or fully liberated from its host rock for a.
distribution as a simplified model for estimating energy losses. Only one production datum is required, which is the electric power of the grinding mills. Recovery of the thermal energy is not simple since the temperature range of the 7 grinding mills studied ranges from 18oC to 38oC. This is a difficult energy source to recover.
After a mineral deposit has been identified through exploration, the industry must make a considerable investment in mine development before production .. Dry grinding, a higher cost process than wet grinding, is used mainly for downstream processing that requires a dry ground material or for producing a special dry.
