Several grindability tests were developed over the years to design grinding circuits or optimize existing operations. each test has its own strengths and weaknesses and it is imperative to select the proper test procedures to meet project deliverables and minimize the risk ofroject. pilot plant testing of large bulk samples historically constituted the traditional approach for ag or.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.

2.2. bond ball mill bbm standard test the procedures to carry out the bond grindability tests in ball mills and rod mills are outlined in sections 2.2 and 2.3. they are usually referred to as the standard tests, but it must be highlighted that the procedures havent been defined by iso or astm standards.
