Design Method of Ball Mill by Discrete Element Method collected. The diameter of the gibbsite powder was measured using a Master Sizer 2000 (Sysmex Corporation). Details of the experimental conditions are given in Table 2. Results and Discussion 1. Effects of Fins on Ball Motion in the Mill To predict ball mill grinding behavior using the dis
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

#0183;#32;INTRODUCTION Although many factors influence grinding rate and energy consumption in ball mill grinding, liner design {lifter design) is one of the most important parameters. Mill liners {lifters) are the agents to transmit energy and impart motion to the grinding balls, which in turn comminute ore particles( Dunn, 1976).
Improving knowledge of grinding technology and mill operations to operate, optimise and troubleshoot ball mill and vertical roller mill grinding installations. Ball mills and vertical roller mills are used for many grinding applications in cement production: raw meal grinding,
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill amp; ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment. In present day practice, ore is

involve grinding). With Lloyd''s 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 Lloyd''s research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

#0183;#32;Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill. When no grinding medium is charged it is known as an autogenous mill. In this chapter, we initially discuss the design and operation of tubular mills followed by ball mills.
Lengthdiameter Ratio of Ball Mill: it relates to the ball mill production mode. For the ball mill of open circuit grinding mode. In order to ensure the fineness of the final product is qualified for the first time, the lengthdiameter(L/D) shall be ; For the closed circuit grinding ball mill, in order to enlarge the discharge value of the
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.
