A manufacturing plant had a machine that would process 6mm ceramic beads into small medical components. They used a screw type conveyor to move the ceramic beads from a large container into a hopper above the machine. In this situation, the customer called EXAIR prior to determining which mechanical component failed. They contacted the conveyor manufacturer for assistance. Because of the complexity of the conveying system, it would take time to evaluate. They had to determine if it was the motor, the gear box, the shaft, or electrical system. Depending on which item that failed, there was a good chance that it would not be in stock. With this length of downtime, it would cost the company much money and delays in shipments. The operation had to be shut down until they could find a way to keep the hopper filled with ceramic beads. Being that they were under the gun, they contacted EXAIR to see if we could help.
In discussing their layout, the hopper was 10 feet away from the supply container, and the opening of the hopper was 10 feet above the floor. These lengths were well within the limits of the EXAIR Air Operated Conveyors. I suggested the model 152200 Heavy Duty Line Vac Kit. This unit has the highest conveyance rate, and it can move items in the range of plastic pellets to steel shot. It does not have any moving parts, so it makes it very simple, reliable, and long lasting. The Heavy Duty Line Vac is made of a hardened steel that makes it very resistant to abrasion. The next question he asked was if we had it in stock. We did!!! EXAIR stocks every cataloged model number for same day shipping with orders placed before 3 p.m. EST. We were able to ship the Heavy Duty Line Vac that same day to get his operation back up and running. He did mention to me afterwards that he wished he had at least one Heavy Duty Line Vac on his shelf as a backup system. It could have saved his company an entire day of downtime.
If your company relies on mechanical conveying systems to move product, you may want to have an EXAIR Air Operated Conveyor on hand just in case of an emergency. When things go wrong, you do not want to be down any longer than needed. If you need help in sizing the correct Line Vac for your application, you can contact an Application Engineers at EXAIR.
