further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density. The underflow from the cyclones is sent back to the mill to be reduced further in size, generally

Effect of Water Density on Grinding Mill

29/07/2015  The amount of water that the mill requires to grind the ore, properly, varies depending upon the type of mineral and the characteristics of the Native rock that it is found in. Some concentrator plants require a very accurate control of the water addition. To do this there has to be a method of measurement. A way to gauge the amount of water that is to be added, to the ore, to maintain the correct ratio between ore and water.

The ball mill is in a closed circuit loop with sump and sieve bend. The sump has a feed of 60.1% solids,water addition to sump is 100 cubic meters per hr and outflow from sump constitutes 49.1 % solids.This feeds onto a sieve band which has an under-screen flow of 42.9% solids. The overflow from the sieve bend (56.1% ) feeds into the ball mill which has a water addition of 67 cubic meters per hr.The ball mill

Ball Mill - an overview ScienceDirect Topics

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...

LIME SLAKING SYSTEMS Bulk Handling Technologies

Too little water will result in insufficient water to slake the quicklime and potentially causing build-up in feed pipes and chutes as the mixture becomes too thick and cohesive to flow through the system. Following slaking, water is then added for dilution to achieve the required final solids content of the slurry. Ball Mill The ball mill has two primary functions within the quicklime slaking ...
