IN BRIEF

Pneumatic Conveying of Copper Concentrate Abrasive

Abrasive Environment

The customer approached Macawber for developing a solid solution for the unique challenge of both an abrasive and corrosive environmental conditions in their copper ore processing plant outside the large copper mine located near Liaocheng in Shangdong Province, China. Due to other systems in the processing plant, including chemical processing systems and open mechanical conveying systems of questionable quality, the customer decided to take the first step in developing a cleaner plant and selected several Macawber pneumatic conveying systems for processing the various materials used in copper processing. Copper concentrate is a minimally processed ore product and one of the materials the customer chose to handle using Macawber systems.
