Advantages and Disadvantages

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product ...

Since their early application, semi-autogenous grinding (SAG) mills have provided the modern mining industry with workhorses used for most high-throughput comminution applications. These mills can functionally replace most of the crushing equipment in a comminution circuit, resulting in a tight footprint and reducing common issues experienced ...

SAG Mill process control classically maintains the SAG mill volumetric filling within a set operating range. Typically a SAG mill weight measurement, by either bearing pressure transducers or load cells, is used as an inferred measurement of volumetric filling. To maintain volumetric filling within a set operating range the SAG weight setpoint use for process control …

SAG mills consume significant amounts of power, water, and consumables, and thus pose sustainability- and OPEX-related challenges. Image: FLS. North American Mining • June 2024 • 23 SAG mills provide the modern mining industry with workhorses able to manage most high throughput grinding tasks.

A SAG (Semi-Autogenous Grinding) mill is a giant rotating cylinder filled with grinding media and the ore being reduced. As the mill rotates, the grinding media lifts and the impact crushes the feed material. SAG mill control refers to the practice of managing the mill load, which is the amount of material inside the mill at any given time.

Since it is now possible to achieve design tonnage at start-up, it is recom-mended to use a 'mill design by ore hardness measurement and calculation' method, similar to Bond methodology, …

Q1. What is a SAG mill used for? A SAG mill is used to grind and crush large pieces of rock into smaller pieces of rock, gravel, or dust. It is commonly used in the mining industry. Q2. How does a SAG mill work? A SAG mill uses a combination of impact and attrition to grind the material.
