SGS has unrivaled expertise in conducting bench-scale tests, such as the MacPherson Autogenous Grindability Test to design power-efficient grinding circuits. We have evaluated more than 750 ore samples from more than 300 deposits using the MacPherson 18" mill test.
The Autogenous mill is designed for dry grinding of raw bath (cr yolite) mixed with other mate rials as aluminium modules or sheets, ir on scraps, papers, etc.
Autogenous Grinding Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5-½' diameter mill had both pebble ports and ½" wide slotted grates. The plus ½" mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½" …
AG Autogenous amp SAG Semi Autogenous Mill Design Calculations. Mill Sizing After laboratory and pilot plant testing confirm the feasibility of autogenous or semi autogenous grinding it can be used to establish the exact grinding circuit and mill size In the pilot plant tests the tare power of the pilot plant mills should be determined before and after each test run The tare power should be ...

Autogenous mills, or AG mills, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
The special characteristics of the Autogenous mill are stated, and a suitable type of model for the mill is presented. An Autogenous Milling defined as used in this study; the term Autogenous ...
The designs of autogenous and semi-autogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.

Many other papers on autogenous and semi-autogenous Bassarear and Sorstokke of Cyprus Pima reviewed the test work they performed to develop their semi-autogenous ball mill grinding circuit. Many other papers on autogenous and semi-autogenous grinding also discuss the pilot plant and bench scale testing done to prove grinding circuits.
Grinding mill process design. Choosing an appropriate grinding circuit configuration depends on your ore characteristics and mine plan. Outotec has extensive knowledge of comminution technologies and processes to ensure we provide the optimal solution for your needs.
Design Of Autogenous Grinding Mill. The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself In conventional milling, the ore is crushed to, plus or minus, 3/8 of an inch, before it is put into a mill for grinding...
Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the grinding action and …
Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills 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.
