With a total production capacity of 20,000 cwts. of flour per day, ADM Milling Co.'s flour mill at North Kansas City, MO (816-221-7272), also produces a large volume of millfeed, both in mash and pelleted form. The mill ships millfeed by both truck and rail through the same loadout system, using a two-way diverter to route millfeed either to a semi truck or a covered hopper railcar. Because ADM Milling sells more than one type and grade of millfeed, it's important not to have cross-contamination between different grades of millfeed. An airtight seal on the diverter is critical to preventing that sort of contamination, says Project Engineer Rick Corbett, at
ADM Milling's engineering center in Salina, KS (785-825-1541). The company was quite interested when Salina Vortex Corp., Salina (785-825-7177/www.salinavortex.com), announced the development of its new Seal TiteTM two-way gravity diverter valves. 'They're located right in the same town with us,” Corbett says, 'and they showed us what they were working on (during product development). We were definitely interested.”
Products & Services
Rodless cylinders are linear devices that use pressurized fluid to move a load within many power transfer operations.
Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting.
Hydraulic cylinders are actuation devices that utilize pressurized hydraulic fluid to produce linear motion and force.
Cylinder Repair Services
Cylinder repair services rebuild and refurbish used or damaged cylinders. They disassemble and clean cylinders, inspect them for cracks and other damage, and re-hone cylinder surfaces.
Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often unsupported.
