In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
With ore grades declining and cost pressures rising, high-throughput circuits based on very large grinding mills are becoming an increasingly attractive option in mineral concentration applications.
The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

"The design/optimization of the pump and cyclones to maximize grinding circuit efficiency first requires a concise understanding of, and clearly defined specifications for, desired grinding circuit performance. Subsequently, the pump and cyclone performances that provide the desired grinding circuit performance can be defined.
and examine the use of the technology in conventional grinding applications (P80 20 - 150 µm). Recent installations will be examined, including fine and coarse grinding applications, as well as the recent test work that was undertaken using an IsaMill™ in a primary grinding circuit, and the resulting circuit proposal for this site.
Over-grinding does not have a significant benefit to gold recovery but reduces the mill throughput and results in higher unit costs in terms of energy, grinding media and reagent consumption. If there are frequent changes in ore hardness, grinding circuit performance is affected and poses challenges for operators to maintain the target particle ...

Grinding Ball Fragments in the milling circuit impact on two critical areas. One is the crushing circuit where companies have observed damage to crushers, unscheduled downtime and loss of production. The other is the grinding circuit where companies have discovered wear to pumps, sumps, piping, hydrocyclones, mill liners as well as inefficient
Fragments of grinding media eventually accumulate in the ore being processed and can cause serious damage to other equipment in the grinding circuit such as pumps and hydrocyclones. The foremost reason to use a trunnion magnet system in a ball mill is to .

autogenous grinding and ball mill grinding—these mills are known as Semi-Autogenous Grinding or SAG mills. Water is added to the ore during the grinding process. This creates 'slurry', which is then used to transport the ore throughout the remainder of the extraction process. SAG Mills constitute a recent innovation in terms of ore ...

Description. A 14/12 millMAX TM pump was installed in the SAG1 grinding circuit as a trial replacement for the existing 12/10 for performance comparison and in an attempt to overcome process difficulties. Krebs Engineers have developed the millMAX TM pump wet end to adapt to a variety of power frames. This system has been developed specifically for coarse material contained in mill ...
Mar 20, 2020· In this blog you can read there are multiple reasons for measuring density in the grinding circuit. In most sites a ball mill is used for grinding and a (hydro) cyclone for classification. The slurry needs to be continuously monitored and controlled. Density meters efficiently help operators to monitor and control the grinding circuit, optimize it and prevent process failures.
Engineered for use in the most aggressive duties, mill circuit pumps easily manage large size particles in highly abrasive slurries, the company reports. These pumps are designed for the most severe slurry applications such as ball and SAG mill cyclone feed as well as water-flush crushing in mineral processing plants.
