  • Grinding in Ball Mills: Modeling and Process Control

    The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 05 to 35 The starting material can be loaded either through a spout feeder or by23/11/2013· Ball and Race Beater Mill mill or Fan Mill 11 TYPES OF MILL • Tube or ball mills: These are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder • Vertical spindle mill: These are mediumspeed machines that include bowl mills, ring roll mills, and ring and ball mills The bowl mills are furthercoal pulveriser SlideShareThe race also dents slightly where each ball presses on it Thus, the contact between ball and race is of finite size and has finite pressure The deformed ball and race do not roll entirely smoothly because different parts of the ball are moving at different speeds as it rolls Thus, there are opposing forces and sliding motions at each ball/race contact Overall, these cause bearing drag "VRace (bearing) Wikipedia

    A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotating about its axis The axis of theThe following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account As well, mills with differentFactors Affecting Ball Mill Grinding EfficiencyAdditional power is required to keep the mill rotating 813 Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure 83 Ad this can be used to establish the essential features of a model for mill power The torque required to turn the mill is given by Torque T Mcgdc T f (89) Where Mc is the total mass of the charge in the mill andTECHNICAL NOTES 8 GRINDING R P King
