New Concept in Grinding for Energy Efficiency

摘要

The objective was to assess the potential energy savings of a laboratory-scale, conveyor-belt-type autogenous (new-concept) mill and compare its performance to a 5.5-ft diameter conventional autogenous mill. The project included provisions for the design, construction, and field testing of a pilot-scale, new-concept mill and technology transfer activities. Comparative tests with the laboratory-scale, new-concept and conventional mills, using taconite ore, revealed the new-concept mill as inefficient in terms of process and mechanical energy requirements.
