MINERAL PROCESSING

MINERAL PROCESSING - MILLING Introduction Milling, sometimes also known as fine grinding, pulverising or comminution, is the process of reducing materials to a powder of fine or very fine size. It is distinct from crushing or granulation, which involves size reduction to a rock, pebble or grain size. Milling is used to produce a variety

process, providing sufficient size reduction in a single process. Alternatively, it can be part of a two stage process where further size reduction is required. Characteristics: This type of mill is only suited to certain kinds of mineral - one which has a fairly coarse nature but once it is broken will disintegrate readily into a small size.

Crushing in Mineral Processing

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

Clearly size reduction provides more surface area that w൯uld be accessible to gas or liquid reagent – if we halve the diameter we get 4 times the surface area: the 1/d squared relationship.

Size Reduction, the Three Laws of Comminution, and the Bond Equation

According to Gupta and Yan (2016), it has been found that the von Rittinger equation is more applicable for coarse size reduction, while the Kick equation is more appropriate for finer size reductions in the region where large surface areas of particles are exposed as in the case of grinding operations.
