Modernize your processes by totalizing and proportioning flow of dry ingredients — b y weight Totalizing flow of shredded rubber. Used tires axe shredded before feeding to the devulcanizer. The total weight is registered by a Toledo-Chronoflo* Batching Conveyor Scale and the flow automatically stopped when the pre determined quantity has been delivered. (Upper photo). Proportioning flow of three dry rubber stocks. ToledoChronoflo Control Scales enable the operator to pre-set the percentages of the prescribed formula. The Chronoflo Controls automatically regulate the speed of each stor age bin discharger to maintain the exact proportions. (Lower photo) Chronoflo Totalizers register the weights of delivered materials on instruments conveniently lo cated for supervisory control. If these applications suggest uses in your plant, write for detailed information, layouts, and prices. *Trade marks registered in U. S. Pat. Off. A . C S.
