The document outlines a project to reduce dust at a direct reduced iron (DRI) plant. A team was formed to identify dust generating areas, reasons for dust generation, and potential solutions. The team conducted site visits, meetings, and feasibility studies. Key solutions identified included modifying chutes and ducts, installing impact idlers, dust suppression systems, and improving housekeeping. An action plan was created and progress was tracked. Video recordings showed dust reduction of 30% so far in the targeted areas. The next meeting was scheduled and the team thanked DRI staff for their support in reducing dust emissions.

Project: Reduction of Dust at DRI Plant AIM: Dust Free DRI
Agenda & Task Identification Area identified by external trainers from SSU DRI Division Identification of most dust generating areas. Reason of dust generation in this area. Are these reasons creating dust generation in this area AVOIDABLE or UNAVOIDABLE. Can these reasons be eliminated without affecting the process. What machine or methodology is at place to control pollution. What is status of these machines in terms of maintenance, performance, availability & utilization. Are machine and methodology adopted are adequate and effective. What can be alternate arrangement to control the dust. Are the workmen aware about the pollution control devices. Is there any procedure to define to control pollution at this place. Taking suggestion from the area in charges.
