The basic parameters used in ball mill design power calculations, rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit openclosed[email protected]
you cannot use work index analysis for the same purpose on ball mill circuits because of the complex interactions between grinding and classification. In this module, you will learn how to relate design and operating variables to ball mill circuit efficiency through functional performance analysis. This Introduction is seven pages long.

involve grinding. With Lloyd39s ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd39s research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
DESIGN, FABRICATION AND TESTING OF A LABORATORY SIZE HAMMER MILL AJAKA E.O. and ADESINA A. Jaw crusher, Ball mill, Burr mill and many others. Thus, of all the crushing machines available, the Gyratory crusher, jaw crushers and the hammer mill are the most widely Design theories and Calculations
Equation 1 is multiplied by the factor of 1.08. A multicompartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.

Figure 5. Highlow wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous AG or semiautogenous SAG mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
