Relationships between comminution J energy and product

Table I shows the Bond ball mill work index obtained for the ore samples as well as the iron and silica content in concentrate and tail after LIMS The concentrate weight recovery was in the order of 50–60% Furthermore it may be observed that the Bond ball mill work

Ball Mills

A Ball Mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill The larger the diameter the slower the rotation If the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back

Bond Work Index

The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12 7 mm ( inch the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard 14 mesh see Chapter 4 for definition of mesh) thus determining the rod mill work index (Wi R or RWi)
