Sep 17, 2021 Design of Tubular Mills. 3. Operation of Tubular Ball Mills. 1. Introduction. The usual objective of reducing the size of run-of mine ore pieces is to separate the mineral of interest contained in the ore body from associated gangue minerals. As crushing only does not generally liberate a mineral, further size reduction is usually required.
GRATE BALL MILL ROM Ball Mills 3.Run-of-Mine Ball Mills (ROM Ball Mills) Run-of Mine Ball Mills can accept ROM up to 150 mm. The large feed particle size reduces effective Ball charge carrying capacity of the Ball Mill, thus ROM Ball Mills typically operate between 20-32% Ball charge. ROM Ball Mills carry a low aspect ratio can
