Cone milling is one of the most common methods of milling in the pharmaceutical food chemical and associated industries They are typically used for size reduction and deagglomeration or delumping of powders and granules Generally used for reducing material to a particle size as low as 180m (80 mesh) they produce less dust and heat than alternative forms of milling traditional chemical milling (CHM) process will face the challenges of decreasing production demand average chemical waste processing cost increasing and the new numeric control machine milling techniques' competing see Figure 1-4(AEROLIA 2010) One of the impacts of the reduction of chemical milling parts is excess capacity

For this rea- son milling plays an important role in many industrial fields (construction materials mining industry chemical industry food industry) About 4% of the electric energy production worldwide is used for milling processes and about 1% of the industrial production is produced using milling processes

Chemical milling

noncutting removal processes (1) in chemical milling the metal is removed by the etching reaction of chemical solutions on the metal although usually applied to metals it can also be used on plastics and glass (2) electrochemical machining uses the principle of metal plating in reverse as the workpiece instead Read More
