Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
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 open/closed
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
Ball Mill Sizing With Bond Method Work Index Base. 1. introduction. a bond ball mill work index test is a standard test for determining the ball mill work index of a sample of ore. it was developed by fred bond in 1952 and modified in 1961 jkmrc co., index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating theget
#0183;#32; Approximation Methods for Work Index. The Bond method of measurement of the grindability of ores in rod mills and ball mills is long and tedious and requires a standard set of grinding conditions; mill size, ball charge, etc. A number of approximate methods have been reported that shorten or approximate the work index estimation.
