Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, by impact or crushing, or by attrition. A mill is charged with media and activated by a high speed agitator shaft to separate the individual particles.
The chemical composition was determined by wet chemical analysis. The microstructures were investigated of the prepared samples using standard metallographic technique. The hardness measurement was carried out by using digital Rockwell hardness tester. The wet wear test of grinding media balls was done by using laboratory scale pot mill. 3.
In the wet milling process, the boron powder and tungsten carbide ball were put into the milling jar as in the dry milling process. Also, 15 ml of anhydrous hexane as a solvent and 1 ml of oleic acid as a coating material were added to the milling jar.
Both of the dry and wet ball mills are composed of feeding port, discharging port, turning part, and transmission parts such as retarder, small transmission gear, motor, electronic control. The wet grinding can be widely used, because most of the minerals can be wet milled.
Wet ball milling processes produces smaller particles, compared to dry ball milling process. Introduction Of Active Surface Media Wet ball milling allows easy introduction of surface active media having to do with the reduction of the required energy for the inhibition of aggregation of fine particles.
The ball mill can grind ores and other materials, wet or dry. There are two kinds of ball mills according to their ways of discharging material: grate type, and overfall type. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.
The ball mill contains a hollow cylindrical shell that rotates about its axis. This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it. Ball mills are classified as attritor, horizontal, planetary, high energy, or shaker. View chapter Purchase book
