Grinding Abrasive Recovery FINE MAG

In parts grinding processes, scratches generated on workpiece surfaces have been causing quality problems in the production scene. These scratches are primarily caused by the whetstone dressing in the grinding process and the grinding abrasive separation during the process. The grinding abrasives that are inherently non-magnetic material are recovered with paper filters or centrifugal separators. However, traditional recovery methods raise problems of high running costs, extensive maintenance operation, and coolant temperature increase brought by centrifugal effect. Specifically, the coolant temperature increase requires the operator to install auxiliary devices, including supply pumps and temperature controllers for use in coolant cooling, all of which need wider installation and operation space. The grinding abrasive recovery FINE MAG is new magnetic separator. Although the magnetic separator originally recovers magnetic materials, new product can recover grinding abrasives and sludges separately. This equipment makes it possible to recover about 80% of this waste within it. In addition, sludges and grinding abrasives are separated and recovered and, therefore, Sumitomo Heavy Industries Finetec, Ltd. expects these materials that have been handled as industrial waste will be recycled.
