A tubular grinding mill is often employed for efficient size reduction use 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
iron ore
To produce best utilization of low grade iron ores available these days worldwide, some sort of beneficiation process has to be performed to make sure 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 can be sintered ahead of the melting operation.
Cement
The essential raw material for producing cement is really a carbonaceous rock called limestone. Additionally, other partial substitutes for example blast furnace slag, pozzolanas, fly-ash etc can be used for various purposes. The cement manufacturing process involves several stages of size reduction by crushing and grinding, one of the most critical being the ultimate grinding of clinker following the raw material continues to be thermally processed in a kiln. This finish grinding operation is most vital because the properties of cement depends, to a large degree, around the particle size that is a controlling parameter for the cement manufacturers.
Coal
Coal is frequently ground for use as pulverized fuel, the most frequent application being power generation. It is really an operation which is sometimes carried out by ball milling, however it is additionally a field where a vertical spindle mill is predominant.
COPPER Along with other NON-FERROUS ORES
These metals are typically 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 will be achieved by a flotation process according to either differential densities or chemical activation.
