The results showed that the HPGR – ball mill circuit achieved a 21% energy reduction over the existing SAG – ball mill circuit under the same P80 grind size of 160 μm. There is also a well-known HPGR application at Cerro Verde copper mine in Peru which has been presented by Vanderbeek et al. (2006) in detail.

The grinding mill is one of the important mining machines. When grinding materials, the output of grinding mill will be affected by many factors, mainly by the particle size of the finished product, the hardness of the material, the humidity of the material, the composition of the material, the viscosity of the material, the working efficiency of the supporting measures of the equipment, etc.

The feed size distribution together with the ore characteristics (hardness, lithology, alterations, etc.) are the most important factors affecting the SAG mills performance.
Pellet mill performance can be significantly affected by the physical and chemical forms of the calcium and phosphorus sources used in the formula. Sutton (1979) investigated the effect of defluorinated phosphate (two particle sizes) and dicalcium phosphate (18.5%) on pellet mill performance with a broiler grower formula.

Equinox Gold is a Canadian mining company with six producing gold mines, a multi-million-ounce gold reserve base and a strong production growth profile from four growth projects. The Company is delivering on its growth strategy, advancing from a single-asset developer to a multi-mine producer in just two years, and is rapidly advancing toward its million-ounce vision.
This quantity is small compared to the power used by a semi-autogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW. However, the energy used for fine grinding is still significant.

Factors That Affect Ball Mill Grinder Capacity And Quality 7 factors that affect the output of ball mill machine The grain size of raw material. Since the vertical kiln cement plant uses the small ball mill, the grain size of raw material can greatly affect its capacity and quality.
Because these are critical factors affecting grinding efficiewe can use DNN to correlate vibration profiles to mill performance. Let's elaborate on this because it is a really cool technology.
Optimise your mill capacity and throughput. Increase liner life and cut replacement downtime. Cut energy costs. Reduce safety risks to employees. Optimise SAG mill capacity and avoid unnecessary downtime. SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock.
important factors affecting the SAG mills performance. Some oper-ations have recognised an opportunity in the relationship between feed size and mill performance and manipulate feed size to obtain efficiency improvements (Morrell and Valery, 2001). The specific energy does not just depend on ore competence but also on factors
