A tubular grinding mill is often used for efficient size reduction application of variety of products such as metallic ores, coal, cement, refractory, pigments and chemicals with the purpose varying from product to product.
Tubular grinding mill application
Cement
The basic raw material for producing cement is a carbonaceous rock called limestone . In addition, other partial substitutes such as blast furnace slag, pozzolanas, fly-ash etc are used for various purposes. The cement manufacturing process involves several stages of size reduction by crushing and grinding, the most critical being the final grinding of clinker after the raw material has been thermally processed in a kiln. This finish grinding operation is most vital as the properties of cement depends, to a large degree, on the particle size which is a controlling parameter for the cement manufacturers.
iron ore
To make best use of low grade iron ores now available worldwide, some type of beneficiation process needs to be carried out to ensure efficient blast furnace operation. Pelletisation is one such process which relies upon the ore being ground to separate the iron bearing particles from the gangue, the ore subsequently being formed into pellets which are sintered prior to the melting operation.
COPPER AND OTHER NON-FERROUS ORES
These metals are normally extracted in the form of very low grade ores, which requires complex processing to extract useful minerals. Initially the metallic ore particles must be physically separated from gangue materials by milling. Subsequent separation is then achieved by a flotation process based on either differential densities or chemical activation.
Coal
Coal is frequently ground for use as pulverized fuel, the most common application being power generation. This is an operation which is sometimes carried out by ball milling, but it is also a field in which a vertical spindle mill is predominant.
