The terms wet milling and dry milling are overarching concepts that do little to actually describe the processes and forces involved. But some methods are only possible under wet conditions, and some require dry milling conditions. Although the goal of both grinding methods is to reduce particle sizes to a target range, the processes are different.
Read MoreBall mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
Read MoreUnlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other. Of course the surface tension of the liquid used will greatly affect the ability ...

Read MoreThe type of ball mill is related to the water content of ore. For the type of MQG dry grid ball mill, water content of ore should be controlled strictly before grinding. High water content would easily led to the solidarity of ore, blocking the grid linder of ball mill, and making difficult for ball mill to discharge.

Read Moresolution is to dry the material prior to grinding, or dry and grind it at the same time by sweeping hot air through the mill. As an alternative, water can be added to the material and it can be ground wet; this solution is suitable for ham-mer mill operation but not for jet mills. Melting point and thermal instability. Jet mills can grind
Read MoreThe choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling …

Read MoreWet milling is milling using cutting fluid. Although dry milling can extend the tool life, the cost of cutting fluid treatment, health and safety issues are attracting more and more attention. The use of dry processing is a very valuable saving in technology, but in some cases, only wet processing can be selected.
