However, as the production progresses, the powder extraction rate will decrease, which will affect the production ...

Mar 02, 2014· 3.1. Industrial Ball Mill The ball mill utilized in the sampling survey has an inside diameter of 7.3 m and length of 9.6 m and is run in open circuit. Under normal operating conditions, the mill ball loading is 30% of total mill volume, mill rotational speed is 75% of critical speed, slurry solids concentration is 75%, solids feed rate is 330 tph.

Thus, in a given grinding circuit, for a certain feed rate, a pebble mill would be much larger than a ball mill, with correspondingly a higher capital cost. However, the increase in capital cost is justified economically by a reduction in operating cost attributed to the elimination of steel grinding media.

Therefore, the operators of ball mill need to check the steel ball situation regularly, adding steel ball reasonably and ensuring the stable production of ball mill. 5.Strictly controlling the grinding concentration of ball mill. Generally, the grinding concentration influences the pulp proportion, fluidity and degree of adhesion of steel ball.

Jul 18, 2016· The mill is equipped with a discharge diaphragm at the end. This diaphragm retains the grinding media in the second chamber and allows the discharge of finely ground material. Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement.

Improve The Crushing Rate Of Ball Mill. Considering from the grinding media, another method to achieve energy saving and consumption reducing is to accurate the diameter of steel balls, and make the steel balls with proper proportion and make the grinding media has proper shape.

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.

The grinding fitness is one of the main factors affecting the mineral processing index,which will directly affect both the grade of concentrate and the recovery rate of product. Therefore, how to improve grinding fineness of the ball mill becomes an important part of controlling grinding operation cost.

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.
