Abstract: A pulverizing pass having at one side an adjustable crushing plate which forces the material entering to pass between the plate and variable speed replaceable rotating hammers which are substantially open causing the material to be pulverized. The chamber is lined with plates which can be repeatedly replaced. In addition, heat is applied to the material throughout the process by two open flame furnaces whereby the material exits dry. Further a means for removing contaminants from the glass is accomplished by three blower devices which suck the contaminants into three collection bags whereby the finished product exits 99.9 plus % clean.
