Ball mill is mainly used for grinding in mining metallic minerals and nonmetallic minerals cement refractories chemical power plant aluminum building material ceramic steel slag and fly ash ect It follows more crushing and less grinding principle to save energy The feed size to ball mill shall be smaller than 25mm the output size can be adjusted by revising steel balls ratio.
Ball mill load parameters VDChari Ball mill load parameters When maximum and minimum ball sizes are known it is necessary to define the proportions in which different sizes will constitute the load Loads can be characterized by two parameters each one of them contributes in a different way to the grinding process Unitary weight.
A large number of process variables affect the performance of ball milling such as milling time powder to ball weight ratio speed of milling eccentricity of the bowl on the disc volume of the material to be grounded medium type of mill jar dimensions milling temperature milling.
The aim of this work was to optimize the ball mill based refining process of chocolate in terms of refining time and energy consumption Experiments were planned following a central composite design CCD considering refining time rt and agitator shaft speed as as factors The experimental variables measured were chosen from the main characteristics that describe unmoulded chocolate.
There are a lot of parameters used in ball milling process However the parameters that have been tested most for optimization are the rotation speed and milling time This indicates that these two parameters play an important role in determining the effectiveness of the milling.

81 Grinding 811 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type These mills exist in a variety of types rod ball pebble autogenous and semiautogenous The grinding action is induced by relative motion between the particles of media the rods balls or pebbles.
These parameters are thoroughly studied in 4 5 and an empirical relation is suggested expressing the mill capacity as a ratio approach is most frequently used in ball mill grinding circuits.

Ball mill circuit classification system performance is considered here first because it provides the basis for subsequent characterization of ball mill breakage efficiency.
Major design and operating variables in closed circuit ball milling of a specified feed to a desired product size are summarized in Table 1 The purpose of process modelling is to establish cause and effect relationships between physical design and operating variables and the performance objectives of the circuit Subsequently output and efficiency can be maximized The fundamental issue addressed by ball mill circuit modelling is thus depicted in Figure 1 McIvor 1989.
Steady state models provide the plant metallurgist with performance parameters which can be calculated and compared from two or more sets of operating data.
In the simplest form of plant experimentation a key performance parameter such as the fineness of the final product is measured with and without a specific change to the circuit Within the constraints imposed by the accuracy of measurements and assumptions about the constancy of other inputs including the ore characteristics the relative values of this parameter are used to evaluate the effect of the change on circuit performance.
Bond work index analysis takes this method of experimentation several steps further During comparative testwork variations in the ore grindability grinding energy input and feed and product sizing are measured and accounted for through the grinding circuit 8220model8221 embodied in the work index formulation For each set of data both the circuit operating work index and the laboratory test work index of the circuit feed are determined Relative work index efficiencies with and without the change to the circuit can then be calculated and compared.
All the production of new product size material takes place in the mill as 8220coarse8221 is ground into 8220fines8221 However the proportion of the total mill power applied to size reduction of coarse particles is equal to the fraction of coarse solids inventory or the so defined circuit classification system efficiency.
The energy specific grinding rate of the coarse material in the ball mill can then be defined as follows.
The mill specific grinding rate reflects both the efficiency of the mill environment in breaking the coarse particles as well as the grindability characteristic of the ore over the particular size reduction range.
To arrive at a term which reflects only the efficiency of the mill environment we must factor out the grindability of the ore such as the net grams per revolution measured in a Bond work index test This will yield the specific grinding rate in the plant ball mill relative to the measured specific grinding rate in a standard test mill and may be termed the 8220grinding rate ratio8221.
