Magnetic Separator
Wet magnetic separator is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals.
The first two GrindingEfficiencyMeasurement examples are given to show how to calculate Wio and Wioc for single stageball mills. Figure 1. The first example is a comparison of two parallelmillsfrom a daily operating report.Millsize 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows thatMill2 is slightly more efficient thanMill1 even though it has a higher power ...

This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
Chute feeder is a kind of feeding equipment which is earlier used in storage trough and it is suitable for the short-distance transport of metallic and non-metallic materials.
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.

Aug 30, 2019· 1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
Dec 26, 2017· Several factors affect theefficiencyof aball millfor cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grindingefficiency:MillGeometry And Speed. According to Bond (1954), the grindingefficiencyof amilldepends on theball milldiameter, size of the media andmillspeed.
Ball millingaball millwith a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions,efficiencyfactors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
Theball millis a tumblingmillthat 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 minimizeballcoating, or slurry containing 20–40% water by weight.

The high energyefficiencyof stirredmillscompared toball millsis well understood. The use of towermillsas an energy efficient alternative to secondary and regrindball millingbecame a common inclusion in the latter part of the previous century. Traditionally the higher energyefficiencywas attributed to the difference between attrition ...
Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. This formula calculates the critical speed of any ball mill. Most ball mills operate most efficiently between65% and 75% of their critical speed.
