7 Differences Between Ball Mill and Rod Mill - Xinhai

The cylinder length-diameter ratio of rod mill is generally 1.5-2.0, while the cylinder length-diameter ratio of ball mill is smaller, only slightly greater than 1. In addition, the cylinder speed of the rod mill is lower than that of the ball mill, so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill

Effect of Ball Size and Ball to Powder Ratio Variation on

Dec 28, 2011· The variation of ball size in a planetary ball mill (PBM) was studied in terms of its effect on the specific impact energy of balls as a result of ball to ball and ball to vial collision calculated through a computer simulation. The mean crystallite size of calcium carbonate in the course of milling as well as the required time for obtaining a thoroughly formed calcium carbonate was also

ATTRITORS AND BALL MILLS HOW THEY WORK Robert E.

A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground). Some are compartmented. M Linings may be made of steel, ceramic, cast basalt, silica or rubber. Ball sizes range is size from 6" diameter,

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 rotati

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 0.5 to 3.5. The

Cement mill notebook - SlideShare

Jan 07, 2015· The difference between ball mill and tube mill is the ratio of the tube length to the tube diameter. Tube mills have a ratio of length to diameter of [3-6 : 1], for ball mill this relation is[<2 : 1]. Two different processes occur inside the mill: 1- Crushing: Breaking up of the incoming particles from a size of about 30 mm to a size of minus 2
