| An asphalt roofing material recycling system and method is used to recycle new and used asphalt materials. The asphalt material is broken up and separated. Dry ice may be added to the recycler and/or a jacket coolant used to cool the recycling vessel. The recycle vessel includes a number of high speed choppers having a blunt end as well as a horizontal mixer element with paddles. The recycled asphalt material is provided to a screener that may feature a plurality of sloping levels, each level including a tray below a screen and balls located within the tray that bounce due to vibration to prevent clogging of the screener. A second processing trip involving gravity feeding the material to be further recycled into a cutter with knife edges to further break down the size of the asphalt material is used for large particles that do not pass through the screener. | ||||||

| 160 | Method for the recovery of secondary polyols from paint sludges | US747700 | 1996-11-12 | US5716996A | 1998-02-10 | Bernd-Uwe Kettemann; Michele Melchiorre |
| The invention relates to a method for the recovery of secondary polyols from paint sludge coagulate, formed from paint overspray which has first been dewatered by mass action, by chemical treatment in a manner such that the recovered product can be reused in the manufacture of paints. According to the recovery method, the organic components contained in the paint coagulate are glycolytically split at an elevated temperature into reusable polyols. Preferably, a mixture of different glycols is used, preferably in an amount of about 20 to 50% by weight based on the dewatered paint coagulate. The addition of glycol dilutes the paint coagulate and makes it flowable. The water contained in the paint coagulate is evaporated and removed during the glycolytic splitting because of the increase in temperature. The impurities contained in the paint coagulate, such as pigments, coagulants or flocculants, can be comminuted and finely dispersed by intensive shearing of the paint coagulate. At the end of the process, these impurities can also be filtered out from the polyols formed. | ||||||
