Getting intense about grinding - CIM
2015-11-02· It is one of the first hard-rock mines to use the High-Intensity Grinding Mill (HIGmill), which has previously seen use in the industrial minerals industry. The HIGmill’s rotating grinding discs stir small ceramic beads, which wear down ore particles to a size where even very fine grained minerals can be liberated. The tall, narrow shape of the mill and the configuration of its discs produce,Rock Mechanics - an introduction for the practical engineer,the application of external forces as in drilling, blasting, cutting and grinding. Both these branches of rock mechanics involve the control of rock deformation and fracture processes. In the first case, excessive rock failure (in this context, failure is taken to mean either excessive deformation or fracture) must be avoided in order to preserve the stability of the structure and, in the,Rock flour - Wikipedia,Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk.
