Mineral Processing Plant Design & Construction Example

The jaw opening is maintained at 1″. The crusher discharge, along with the grizzly undersize, is transported on a 14″ x 65′ conveyor with a slope of 4 3/8″ per foot at 150 feet per minute to the fine ore bin. The conveyor is powered with a 2-Hp., 1200-r.p.m., fan-cooled, totally enclosed ball bearing motor.

ROM ball mill design

I am no RoM ball mill expert and hope others will add to this. RoM Ball mills, like SAG mills, utilise coarse rocks in the RoM feed as grinding media but with 25 – 40% steel balls added instead of 5 – 18 % volumetric filling in SAGs which may become advantageous when the coarse fraction in the RoM feed is depleted.

Introduction to Mineral Processing

In broader terms, mineral processing consists of two functions. Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration.
