A ball mill is a very efficient grinding machine, used for grinding of different materials, such as cement, silicates, ceramics, fertilizer, etc. The ball mill grinds the materials into fine powder and is probably one of the most efficient grinding machines. The working principle of ball mill is very simple. The material to be grinded is loaded into the barrel, which contains grinding balls, known as grinding media. With the barrel rotating, the material is being caught between the grinding balls, which mix and crush the material into fine powder in only few hours. This means that the longer the ball mill runs, the finer powder the material will become.
The ball mill is used for a variety of applications in different industries that need to crush the materials into fine powder. The capacity of most ball mill for sale is about 60 Hz and 115 volts, all capable of operating continuously without any failure. The particle size totally depends on how long the ball mill runs. If the ball mill is allowed to run long enough, it can make the material reach a sub-micron level. For maximum grinding efficiency, it is recommended to use as smaller and less materials in the barrel as possible, because bigger materials may have an impact of the crushing balls and reduce the grinding action. Also, it is recommended to grind and crush the materials few times with a ball mills of smaller capacity than one long process with a ball mill of big capacity.
Grinding media, or more known as grinding balls, are the most important consideration when choosing a ball mill for sale. The most popular choice for grinding media is chrome steel, as it has high-mass and high hardness. With the capacities of the steel, this grinding media can efficiently grinds and crushes a variety of materials with low operators' efforts and in short period of time, with minimal contamination. However, there are some specific materials that require a specific type of grinding media. For grinding rocket propellant or black powder, lead is the only grinding media that can be used. Lead is a very high-mass grinding media, but it is soft and may causes serious contamination to the material in the ball mill.
For grinding very hard materials, chrome steel is the obvious choice. Heavy and hard grinding media, able to grind even glass particles. Ceramic media is also not a bad choice, especially when keeping the contamination to minimum is required. A ball mill for sale with ceramic media is perfect for milling individual chemicals, with only one disadvantage – very slow operation.
