Mineral Processing Equipment : Ball mill of closed system in ukraine - A type of mining equipment that can trigger the development and change of the beneficiation technology industry. The main core machines are ball mills, rod mills, flotation machines, magnetic separators, etc.
Ball mill application: ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. to achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill.
The value of airflow in m 3 /hr can be back calculated using the mill diameter and media fill level to a velocity over the mill internals. however, the disadvantage of this method is that it also includes any false air that enters the mill system after the mill exit, through the mill seals, leaking sample points, air slides and the bag.
Reply: closed-circuit crushing is a means of controlling product top size by screening the product and then returning oversize material to the feed end of the crusher for another pass through the machine. while it may be possible to obtain a specified top size from crushers without using a closed-circuit system, it is not always.
