Terry,
That was a most informative description of your blower system. I am with you and Eric on the vacuum problems. I used to work for a company years ago that used vacuum unloading and conveying for polypropylene pellets. I believe some of the problems we always had could have been reduced or eliminated if we had changed over to a blow system. We certainly would not have collapsing rail car situations, not that we ever did. We used vacuum breakers on all the systems and had a good pm system to keep them set and accurate. It is a very real concern though. We had bridging problems from time to time and we used bridge breakers by Thayer Scale. They were silo mounted vibratory units that would periodically shake the silo and cause the bridge to fall. Actually, since our silos were conical bottom units, we had a more severe problem of rat-holeing than bridging but the bridge breakers worked for both conditions. I am intrigued at the many ways people have solved the problems of material transport. It has always been a favorite subject of mine. Thanks for the additional info.
