AMIT 135: Lesson 2 Circuit Mass Balancing – Mining Mill

A classifying cyclone is treating 150 gallons/min of slurry. A plant technician has measured the pulp densities of the process streams using a Marcy density gauge and reported the following: Ï f = 1.08 gm/ml, Ï o = 1.03 gm/ml and Ï u = 1.20 gm/ml. Determine the volumetric flow rates to each stream.

Hydrocyclone Operation

When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone operation performance.

Ball Milling | Material Milling, Jet Milling | AVEKA

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by

Introduction to Cyclones

This Size Classification is most often seen in milling, where the process requires a product of a certain particle size. 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. A cyclone does this, with the

Ball Mill

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Ball Mill Explained

If a ball mill uses little or no water during grinding, it is a ‘dry’ mill. If a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
