Ball mills are rated by power rather than capacity today the largest ball mill in operation is 853 m diameter and 1341 m long with a corresponding motor power of 22 mw toromocho private communications
May 01 2020 the ball mill capacity q is obtained from the ratio of the power of the pinion required by the ball mill to the unit power consumption of the grinding product as shown in eq the grinding kinetic formula is presented in eq eq is obtained after logarithmic processing 7 n
3 lb capacity media ball mill perfect size for the small hobbyist to mill black powder rocket propellant and other barrel measures 475 high x 45 in diameter
6 lb capacity double barrel ball mill perfect size for milling 2 different comps at once in separate drums 2 barrels measures 475 high x 45 in diameter
For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie
Nov 18 2008 summary the ball mill is designed to grind materials by turning the cylindrical shell with grinding medium eg steel balls put in the shell and has a simple structure and ease of handling furthermore the ball mill of a large capacity has been available to a very extensive range of applications in both dry and wet 14 references 1
Jun 23 2020 one way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge this can allow an operation to increase plant throughput or reduce the product size which can each contribute to higher revenue but there are several factors to consider before the decision to convert is made
