Tubular Pneumatic Conveyor Pipeline. Final Technical Report.

摘要

A section of pneumatic conveying system was constructed and tested at the Milchem Barite Grinding Plant located at Galveston, Texas. Granular Barium Sulphate (barite) was used as the test material. A range of tests were conducted and modifications made to the fluidizing line and uni-directional valves to optimize the efficiency of the system. The test line proved superior to conventional pneumatic conveying lines by increasing the product conveying rate from fifty-six (56), tons per hour with a conventional system to one hundred and forty (140) tons per hour. The low vent loss of 2.1% was due to the test line's ability to convey a denser product flow without line plugging than possible with dilute phase conventional systems. The test line was deliberately plugged with material and rapidly unplugged during a series of tests to determine shut-down and start-up capability. This system may be retro-fitted to existing conventional pneumatic conveying lines with only minor modifications. (ERA citation 10:044855)
