Abrasive wear and attrition

If the wear problem is due to abrasion, the first step should be to test the abrasive wear characteristics of alternate liners (Johanson Royal 1982) and then consider changing the wall material or liner. 

Another operational problem is unacceptable attrition. If this is occurring, consideration should be given to using a letdown chute, reducing the size of the bin or changing the type of feeder to one that provides fewer pinch points.
