Guide On The Grinding Media Ball Manufacturer

Over the years, many different forms of grinding media ball have been tested, but there are really only two types of media that are effective in grinding. The spherical ball and the cylindrical rod are examples of this. Other forms are more costly to produce, and they have not shown any significant increase in grinding performance.

An experienced charge will grind more effectively than a fresh mill charge, according to the results of the study. Obviously, this is hard to predict at the outset, but following the continuous operation, the media charge should be examined for size and weight, and kept at the optimal position determined before. Following the selection of the charge, new media should be created in the largest size that was previously utilized. In certain circumstances, it has been shown to be useful to add replacement media of two or more sizes in order to keep the seasoned ratio as precisely as possible.

Using The Grinding Ball

When using grinding ball mills, the initial charge to the mill is typically between 40 percent and 50 percent of the mill volume, whereas for rod mills it is between 35 percent and 45 percent of the mill volume.

In general, rod mills will have a vacant area inside the charge of roughly 20 percent to 22 percent for fresh rods, depending on the manufacturer. The theoretical empty space in a ball mill is around 42 percent to 43 percent of the total volume. It has been discovered that when grinding rods wear, a 4′′ or 412" rod will typically break apart at around 112" diameter. It is less likely that tiny diameter new rods would break apart as quickly and will normally wear down to around 1 inch in diameter. It has been discovered in many applications that removing rods when they reach the 1′′ size, as well as removing broken portions of rods, can boost the grinding efficiency.
