(5) Simply speaking, the cast ball is the heat-resisting ball (suitable for dry grinding, such as the ball grinder in cement plant), and the forged ball is the corrosion-resisting ball (suitable for wet grinding, large mines, power plants, etc); the cast ball is suitable for the 1.5-3.8m grinder, while the forged ball is suitable for 1.5-11m grinder.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position. The current way to measure the charge filling degree

Dec 08, 2009· Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball 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.
• Ball mill specific grinding rate • Ball mill grinding efficiency The circuit output is defined as the production rate of fines by the circuit. It is calculated from three values: 1. The dry ore feed rate to the circuit (t/h). 2. The % fines in the circuit feed. 3. The % fines in the circuit product.

Grinding Abstract In ball milling the rates of breakage vary primarily with the size distribution of powder in the mill. Using an approximate solution to the batch-grinding equation, the acceleration and deceleration of breakage rates of all individual size classes are determined when the grinding environment is varied. Experimental results with
Rate of ceramic body grinding in a ball mill 191 product applicability. This is related to the use of ground product in the production of ceramic materials that should satisfy strictly specified users' demands.
In this study we conducted grinding tests on silica glass using a ball mill, and measured the grind ing rate constant of the feed size decrease. We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass, feed mass, and the mill's rotational speed were constant. The results indicated that the grinding ...
