Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally.

Every mining operation has a unique grinding process. Variable needs require versatile grinding equipment. Metso offers flexible autogenous (AG) mills,semi-autogenous(SAG) mills, ball and pebble mills, as well as stirred mills to fit your needs.

In SAGmill operation, thegrindingrate passes through a minimum at a “critical size” (Chapter 5), which represents material too large to be broken by the steelgrindingmedia, but has a low self-breakage rate. If the critical size material, typically 25–50 mm, is accumulated themillenergy efficiency will deteriorate, and themillfeed ...

Hammer millis the most widely usedgrinding milland among the oldest. Hammermillsconsist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact.

MillType Overview. Three types ofmilldesign are common. The Overflow Dischargemillis best suited for finegrindingto 75 – 106 microns.; The Diaphram or Grate Dischargemillkeeps coarse particles within themillfor additionalgrindingand typically used for grinds to 150 – 250 microns.; The Center-Periphery Dischargemillhas feed reporting from both ends and the product discharges ...

Themillis filled with thegrindingbeads as well as the product, then themillis rotated until a speed sufficiently high so that the beads can tumble freely. It should be noted that, in some applications, a stirrer is present to agitate the beads, and the drum is therefore not rotating.

Variables in Ball Mill Operation. ... Critical speed (CS) is the speed at which thegrindingmedia will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS.

Jan 05, 2020· BurrMills. The oldestgrindingmodels, these are the most common. Burrs consist of twogrindingplates, either stone or steel. One plate is fixed to the housing unit and is called the “bedstone,” while the other plate is rotated and is known as the “runner.”

RodMillsare particularly useful, if you run a low tonnageoperationand are looking for coarse product. Our RodMillsare available in multiple diameters to fit the needs of youroperation.Grinding, primarily by attrition, RodMillsrequire comparatively low levels of power to operate.

Sanjeev Latchireddi, Chief Process Engineer –GrindingAmericas, Outokumpu Technology, looks at the shift from ballmillsto SAGmills. Nowadays, the more successful plants are those that have adopted effective and efficient strategies to optimize their plantoperation.
