Rely on our proven track record of AG and SAG Mill superiority
Your operation requires cutting-edge solutions with high throughput to enhance productivity and profits. We have designed our AG and SAG Mills with your specific needs in mind. Our team of highly-skilled engineers continually upgrades designs for the consistently most cost effective and robust AG and SAG Mill solutions for your operating needs.
What we offer
Rely on our proven track record of AG and SAG Mill superiority
Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.
SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost the grinding efficiency of your operation.
The mills can be operated in open circuit, feeding downstream secondary grinding, or operated in closed circuit as single stage mills generating a finer product size. 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 engineers continually improves SAG/AG Mill designs in order to provide the most robust, safe, and efficient grinding mills available.
Key design features:
- Robust head castings and shell fabrications resulting in low stress levels and longer operating life
- Mill designs are supported by a full suite of design analysis reports including rotating body finite element analysis, main bearing fluid film analysis, drivetrain steady state torsional analysis as well as gearless mill dynamic modal analysis and system stiffness analysis
- Gearing rated to the latest proven AGMA standards
- High value lubrication systems with potential for flywheel rundown circuits (eliminating nitrogen accumulators)
Key Benefits
Increase efficiency with proven and cost-effective AG and SAG Mill
- Get more done at a lower cost with higher throughput
- Our SAG and AG Mills have been painstakingly designed to reliably provide higher throughput, enabling you to process more at a lower cost.
- Easily find the perfect fit from our wide range of sizes
- We provide SAG and AG Mills up to 12.2m in diameter. Our mills use conventional geared drives for transmitting up to 18,000 kW of power by use of a twin pinion system.
- Depend on years of proven reliability and productivity
- We’ve been producing the highest quality SAG and AG Mills since the 1980s. We also provide comprehensive customer service that includes full lifecycle solutions from installation and commissioning of new equipment, to optimisation support, audits and regular maintenance.
Product Features
Benefit from AG and SAG Mill in many drive arrangements, sizes and bearing designs
Your operation requires a Semi Autogenous Mill (SAG mill) or Autogenous Mill (AG Mill) that is flexible, durable, cost-efficient and tailored to your specific needs and use cases. That's why we offer a full product range from 4.3m to 12.2m in diameter with multiple options for configuration of designs to suit your operation:
Potential for modularisation/segmentation of major components for pre-assembly efforts or for ease of transport
Multiple drive options available including:
- Direct drive systems utilising low speed synchronous motor(s)
- High speed drives through gear reducers
- Single or dual pinion drives (with load sharing technologies)
- Wrap around motors for highest power requirements
Established full line of main bearing technologies to best suit the application such as:
- Hydrodynamic trunnion supported sleeve bearings
- Hydrodynamic shell supported bearings multi-pad bearings (self-aligning)
- Hydrostatic trunnion supported sleeve bearings
- Hydrostatic trunnion supported multi-pad bearings (self-aligning)
Flexibility in feed chute design to suit troublesome ore characteristics (highly abrasive, sticky, etc.)
Various feed end seal arrangements to arrive at the best solution for sealing and liner maintenance
Customised discharge arrangements to suit trommel screens or vibrating screens
Digital solutions to improve performance of your SAG mill
For the best possible results, we recommend our LoadIQ smart sensor technology in combination with our ECS/ProcessExpert Advanced Process Control system. These solutions will provide your business with greater flexibility as together they will automate the response to mill conditions, freeing up your operators for other roles. We have designed ECS/ProcessExpert to adjust mill conditions to improve ore reduction and energy efficiency to help lift your productivity.
