A grinding mill needs a classifier to extract the particles that have been milled sufficiently finely, and to send oversize particles back to the mill for further grinding. ... (80% minus 75 microns etc.). Those gradings are dependent on the size distribution of the feed to the cyclone, and are commonly described as p80, p50, p20 etc.

A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working ...

Add the same weight of grinding rods (or balls) to the mill each time. You would perform this grind tests over to time range to obtain a P80 size range. Say, for this example, 10 minutes, 20 minutes, 30 minutes. After you filter the mill discharge product, perform a full screen analysis (wet screen 400 mesh) followed by dry sieve.

The Huckleberry mine, located in British Columbia, produces roughly 40 million lb/y of copper. A comprehensive energy and cost study compared an existing SAG millbased circuit at the Huckleberry mine with two proposed circuits involving comminution technologies that are associated with energy efficiency: highpressure grinding rolls (HPGR) and highspeed stirred mills.

Mill will grind slower, classifier overflow will thin out, get finer. If fed too fast, a grate mill may plug. Cut down classifier water, and may need to cut mill feed and water. #2. BallMill Discharge: Thinner: Feed too slow or too coarse; too much water in feed. Mill will be underloaded and classifier too dilute.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

The 9 to 10 m (30 to 33 ft) SAG mills now in wide use and the 127 mm (5 in.) balls they require to break primary crusher products testify to the validity of Taggart's work of 60 years ago. An empirical relationship relating ball size to ore properties and mill size has been developed by Azzaroni (1981). F80 = feed size, 80% passing, microns
