What is critical speed of a SAG mill?

The critical speed of a SAG mill is the speed in RPM's at which centrifugal force causes the material being ground to be held against the inside of the shell. This speed is only dependent on the diameter of the mill.


How do you prevent oxidation in a ball mill?

When setting up a ball mill, it is critical to consider what is being milled. Keeping the mill cool and introducing oxygen scavenging materials will greatly reduce oxidation in a ball mill. Sealing the ball mill production chamber and flushing with nitrogen or an inert gas may help depending on the material that is put through the milling process. Additionally, mill speed must be optimized (not too fast or too slow -- it's critical), and the correct material and size for the balls must be selected.


What are various parts of ball mill?

Ball mill is mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (. And belts are used to transmit rotary motion). Functions on the same principle. , but cannot be used in the preparation of some pyrotechnic mixtures such as. Because of their sensitivity to impact. High-quality ball mill is potentially expensive and can grind mixture particles to as small as 5. , enormously increasing surface is and reaction rates. The grinding works on principle of critical speed. The critical speed can be understood as that speed after which the steel balls (which is responsible for the grinding of particles) start rotating along the direction of the cylindrical device; thus causing no further grinding.if you want more,visit: http://www.zdmill.com/ congratuation to you!

What is ball milling process?

Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material. The ball mill is a key equipment for regrinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Our ball mill can grind ore or other materials that can be grinded either by wet process or by dry process. Ball mill is the most common grinding equipment in mining process, and widely applied to the grinding of all kinds of metallic, non-metallic grindable materials. Owing to different ways of classification, ball mill can be called differently. According to dry grinding and wet grinding, ball mill can be divided into dry ball mill and wet ball mill; According to grinding size, ball mill can be divided into grid ball mill and overflow ball mill; According to the barrel length, ball mill can be divided into long cylinder ball mill and short cylinder ball mill.

What is the difference between hammer mill and ball mill ginders Which is more efficient?

A hammer mill uses a pounding motion to grind things. A ball mill grinder uses a roller to grind things. The ball mill grinder is going to be more efficient because the product is pushed through the rollers at a specified thickness.
