Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

Aug 29, 2018· CHANGE IN BALL MILL OUTPUT IF INPUT AND OUTPUT SIZE CHANGES The mill output is a function of mill feed size as well as the product size, if other variables like Mil Diameter, load in the mill, RPM of the mill etc. are kept constant. If input size fraction is reduced the output

Effect of Ball Diameter, or Rod Diameter Variation The first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter, upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling; these curves being deduced from the data of Coghill and Devaney.

The law of ball size distribution (D bsd) in the horizontal planetary ball mill is studied by the DEM, and takes the simulation results compared with the grinding test results, reveals practical significance of the simulation.We have obtained the specific rates of breakage can be determined by the mean contact force. • Friction work reduces with the rise of the larger-size balls in D bsd

The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24%, moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1.5.

For each curve any point underneath represents all the possible output mass fractions that can be obtained from milling the two size classes under different conditions of ball match. The graphs show that for a courser feed a three ball mixture (50 + 20 + 10 mm) will provide the much required largest amount of size class of interest.

May 21, 2009· Abstract: Ball mill coal pulverizing system is a multiple-input multiple-output (MIMO) process characterized with strong couplings and nonlinearities. Conventional control methods maybe work well initially, but will deviate from optimal work point for a period of time and even cease to be functionally effective.

In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies. Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.

CHAENG cement ball mill equipment can reduce energy consumption by 30% and increase the processing amount by 15-20% after transformation. The cement ball mill can perform dry process production and also wet process production, moreover it can do grinding and drying at the same time.
