Pneumatic Conveying Equipment Revolutionizing Mining Efficiency In South Africa

The author explains the advantages of utilizing heavy-duty equipment for dilute-phase pneumatic conveying in challenging underground mining conditions. Although often used for handling fine-grained materials, such as cement and pulverized coal, pneumatic conveyors can also effectively transport larger, heavier materials like abrasive rock and coal. Dilute-phase systems use high-speed air to move particles while dense-phase systems use air at high pressure, provided by a reciprocating compressor or positive-displacement blower.

In the mining industry, both types of systems have their own applications, including the transport of rock dust and mine refuse. Pneumatic conveying has been used in coal mines since the 1920s and has proven to be a valuable method for both hoisting coal and disposing of rock waste. This technique is also used for hoisting extraneous rock from construction projects, making it a versatile and useful tool in the development of mines.

Dilute-phase pneumatic conveying systems offer a range of benefits for handling both fine-grained and larger, heavier materials in challenging underground mining conditions. With the use of high-speed air or air at high pressure, these systems provide efficient and effective transport options for materials such as abrasive rock, coal, and mine refuse. This technique has a long history of success in the mining industry, proving to be a valuable tool for both hoisting coal and disposing of rock waste in numerous applications.

Additionally, it has also been utilized in the construction industry for hoisting extraneous rock, showcasing its versatility and usefulness.
