From mining, steelmaking or cement industries, where flow rates on the order of thousand “t/h” are handled, down to food or pharmaceutical industries where rates as low as “g/min” are handled, they all depend on well designed bulk solids handling processes and equipment to ensure constant and reliable operation, resulting in high quality products.
The Brazilian glass industry produces approximately 3.6 million tons of glass per year in 30 plants. The total amount of raw material handled in these plants reaches 4 million tons per year. Considering all the raw materials used in glass production (e.g., sand, alumina, limestone, cullet) are solids, the knowledge of bulk solids flow should be well understood by the industry. If that was true, problems like batch segregation, excessive abrasive wear, pluggages, and buildup, which hinder plant efficiency increasing production cost and reducing quality, shouldn’t exist.
This paper presents the results of a survey with different companies, to understand how and if the Brazilian glass industry is using available technology to solve or avoid typical operational problem caused by poor solids handling systems.
