If you are thinking of getting into the rapidly emerging recycled asphalt shingle (RAS) grinding business, a key piece of equipment is your grinding system. While productivity and quality control around particle sizing are very important, another key consideration is wear and tear, as shingle grinding is a tough assignment in terms of machine wear.
Here are some leading equipment manufacturers.
Peterson Pacific produces multi-faceted wood grinders that can be equipped with the optional shingle grinding package for use in asphalt shingle grinding.
Rotochopper reports that it has the only machine specifically designed to process asphalt shingle waste, resulting in lower wear and higher efficiency. Following the first link below, you can see a close up of a Rotochopper in action at Gemaco Sales.
