Bulk material classifications for the design of pneumatic conveying systems

摘要

Many products and intermediates in the mining, resource and process industries exist in loose bulk solid form (e.g. pulverized coal, cereals). These bulk solid materials have to be stored and transported during manufacture and processing. Due to its enclosed nature, flexibility and easy automation, pneumatic conveying of bulk solid materials is being used increasingly by industry, for example to minimize dust levels and improve workplace safety. This paper reviews classification diagrams used to predict the modes of flow of bulk materials in dense phase pneumatic conveying.
