How to improve the cleanliness of abrasives

The Importance of Monitoring Abrasive Cleanliness

Mar 03, 2017· Selection of the type and size abrasive is dependent on the degree of cleanliness specified, the depth of the surface profile, the type of substrate to be prepared, and any specification requirements regarding type (e.g., use of expendable verses recyclable abrasive). The cleanliness of the abrasive (whether new or recycled) is equally important.
