A CONVEYOR . . . WITH NO MOVING PARTS!
F-H In this unique conveyor, partly aerated pulverized ma terials flow, by gravity, on a slightly inclined, porous surface. The equipment comprises a lower channel, forming an air chamber, having an upper surface of porous material, usually heavy fabric, upon which the material flows, and a n upper channel to contain t h e material. A novel feature of t h e design is the porous surface of low-air permeability, which assures uniform distribution of low-pressure air, e.g. 6-in. W.G. The most important advantage of t h e Airslide is its remarkably low power requirement, usually about oneTrade marks: "F-H AIRSLIDE" (Patent pending)
tenth of the power of a screw conveyor of similar capacity. The Airslide has been used to convey gypsum, soda ash, barite, bentonite, lime, fly ash, iron ores, Portland cement. and cement raw materials. For further details and information, write for Bulletin FH-1. It will be sent you promptly.
