Metso SAG mills - Metso Outotec

Semi-autogenous as they are often called, 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, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

SAG Mill Tutorial EDEM 2017

Introduction This tutorial describes how to set-up and analyze a SAG Semi-Autogenous mill simulation. There are 12 short steps that will guide you throughout the tutorial. The SAG Semi-Autogenous mill is a machine designed to to grind smaller particles and break larger rocks. Particle breakage will not take place during this simulation. The main focus is on: […]

Autogenous and Semi-Autogenous Mills | FLSmidth

Semi-autogenous uses a minimal ball charge in the range of 6-15% while autogenous uses ore only. SAG and AG Mills operate by lifting ore/ 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 ...

What is SAG Semi-AutoGenous Grinding and How it works

Semi-autogenous is used in place of autogenous when the ore does not produce the necessary competent media. Forged steel balls are used to supplement the coarse ore. In the past, the same ill geometry has been used as in autogenous mills with modifications in the structural design to account for the increased weight of media ...

Improvement of φ5.5 m×1.8 m semi-autogenous mill liners ...

 · The semi-autogenous mill is mainly used for rough . Due to the large ore entering the cylinder, the body is a ball with a diameter of 200 mm single weight of 50 kg. When the mill is working, the local impact force of the body on the cylinder liner is large.

Mill grinding -

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller comparatively diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m 28 ft in diameter with a 22 MW motor, drawing approximately 0.0011% of the total worlds power see List of countries by electricity consumption. However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance. The power predictions for ball mills typically use the following form of the Bond equation: $${displaystyle E=10Wleft{frac {1}{sqrt {P_{80}}}}-{frac {1}{sqrt {F_{80}}}} ight,}$$ where • E is the energy kilowatt-hours per metric or short ton • W is the work index measured in a laboratory ball mill kilowatt-hours per metric or short ton
