Increasing Capacity And Productivity In The Metals Markets Through Pneumatic Conveying And Process Injection Technologies - The Southern African Institute Of Mining And Metallurgy

Pnuematic Conveying and Process Injection Technologies have been implimented in the metals markets for the last 40 years and have consideribly improved the productivity and the performance of many processes. There have been many steps forward in handling technology and this paper seeks to consider those now offered by Clyde Materials Handling who as an established customer-driven solutions provider, which has turned its attention to supporting the Metals Market. Clyde seek to utilises its knowledge, expertise and technologies to transform the production processes of its customers, who operate in the ferrous and non-ferrous metals industries. With over 30 years experience in the process improvement industry, Clyde Materials Handling has helped their global customer base transform the way in which they operate their processes, which has enabled them to generate sustainable economic benefit and maintain their positions as leaders in their respective markets. Operators within the metals market have developed and deployed pneumatic conveying and pneumatic injection technologies. These environmentally supportive and sustain-able solutions have been used to transport raw materials within operating facilities, from storage to silo, as well as injecting these materials directly into the heart of production processes. Operators, such as Codelco in Chile, Corus Steel in the UK, and many others across the World have seen pneumatic injection solutions transform their process and costs. To inject a consistent, pulseless and accurate flow of material to a copper concentrate bath smelter, or injecting granular or pulverized coal as a coke substitute in to a blast furnace via the Tuyeres helps to increase the operational capacity, availability and productivity and reduce the cost of the operation. This paper will discuss and highlight the ways in which pneumatic conveying and injection technologies, created by Clyde Materials Handling, and applied in partnership with the customer, have helped to improve the operational performance of the production processes of operators across the non-ferrous metals markets with specific reference to applications in the Lead and Zinc Industries. With examples from Zinc Fuming in Australia, Zinc Calcine and Powder Handling in Korea, Precision coal injection to QSL and TSL Furnaces, and metered distribution of Zinc Calcine to Reactors.
