Cement plant, the kiln. Based on their design, it is critical to keep the kiln in motion at all times when heated. The inching drive for this application is designed to operate whenever main power is lost for the rotation of the kiln. The second cement application for inching drives is the rotation of the horizontal grinding mills for maintenance.
The OKTM Mill’s flexible design makes it possible to operate it with a number of rollers out of service while still reaching 60 to 70 percent of the normal operation output, minimising production losses. The compact and long-lasting ATOX Coal Mill has the capability to grind virtually all types of raw coal, to your desired fineness. It is.

There are two types of pellet mills, one is a flat die mill and the other is a round die pellet mill. First to be designed was the flat die mill the round die was improved basing on the operating principle of the former. Flat die pellet mills are used for small to medium scale pellet production whilst round die pellet mills.

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300 C. Inert kiln exhaust gases with oxygen content.
