grinding aid agglomerates

The nature of grinding aids means that they promote the formation of dust because they reduce the agglomeration of the finest particles see Figure 3. In certain cases, the filter andor the hopper of the bag filter can become overloaded. This can lead to the wrong supposition that the grinding aid chemically attacks the filter cloth.
