The uniformity and suitability of fractural glass derived from breaking used fluorescent tubes for separation of the glass and potentially toxic powder adhered to the fractured glass prior to disposal and recovery of the components glass and powder is improved by use of a fracture blade having a sharp striking point extending forwardly from a base composed of a flat transversely oriented rotatable striking blade. The blade is preferably, for best results in later separation of the glass particulates and powder, operated at a striking blade speed of 1760 to 3700 feet per minute, providing a uniformity and size of fractured glass upon which a significantly more effective countercurrent air separation can be made. |
