The ball mill was tested as a grate discharge mill and as an air-swept mill. Feldspar was chosen for the tests. ... Ultrafine grinding in an air-swept ball mill circuit ... High performance dry ...
This paper is concerned with the model of a fully air swept ball mill operating in a raw material grinding circuit. For simplicity, the approach assumes that different components in the feed can be treated as if they all had the same breakage and classification properties.
The grinding plant has no dust problems as it works under negative pressure conditions, due to the pneumatic material conveyance. As there are no dust deposits (in contrast to closed circuit mills with bucket elevators), the air-swept mill is especially suitable for grinding coal. A simple plant concept and low capital expenditure typify the ...

BALL MILL is an equipment that is used for size reduction and homogeneous mixing of wet and dry materials effectively. Uni-Mech manufactures specially designed Batch type and Continuous type Ball Mills ranging from 2 Kg to 10000 Kg capacity.
The gas temperature is controlled by cold-air bleeds to ensure a dry product without overheating the mill. The product passes into an air separator, which returns oversized particles to the mill inlet. Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill.
