ATOX® Coal Mill FLSmidth

Our ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleumA mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or Mill (grinding)

Industrial Solutions polycom high-pressure grinding roll

ciency of high-pressure grinding and the polycom ® reveals its full potential. Compared to a roller mill, it is thus able to save up to 20 percent of the energy required for grinding; compared to a conven-tional ball mill, it can even save up to 50 percent. Maximum energy savings are achieved by combining the polycom ®and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size. Higher availability & reliability HRC 8 provides an optimal crushing force with the use of adjustable hydraulic cylinders and variable speed.

Loesche Mills for Cement and Granulated Blast Furnace Slag

The spring-loaded roller grinding mill for grinding coal was intro duced by Loesche in the 1920’s. Since the end of the 1930’s Loesche mills have also been used for grinding cement raw material. The biggest breakthrough in this field of application took place in the 1960’s. Soon after this the cement industry expressed the desire tohydraulic systcm. The grinding pressure on the high pressure sidc of the hydraulic cylinder in U1e range betwcen 50 bar and 100 bar is inducing the grinding forces into the material in the gap between U1e rollers and lhe table.
