Fox Solids Conveying Eductors Blog

In a vastly simplified conveying arrangement – compared to any possible option with rotary valves – one blower is used to simultaneously drive three ceramic-lined eductors. Each eductor is under a different hopper. Each eductor then conveys the abrasives to a different destination. The result – three conveying systems, only one blower with no moving parts.

Aluminum chips, although a soft metal, can be extremely abrasive when conveyed at rates of 5 tons/hr. Fox is supplying conveying eductors with replaceable ceramic liners as well as replaceable tool steel liners. In addition, some portions of the eductor internals are clad with tungsten carbide.

This major producer of synthetic wood and decking has installed another Fox eductor in their new manufacturing line to convey resin pellets with no moving parts – so their production can continue with no maintenance shutdowns from resin conveying. This is just another of many producers of building products that use Fox venturi eductors – including producers of roofing tiles, sandpaper, chipboard, and grout.

A major food processor in Thailand has been using Fox 4 inch, fully sanitary, food grade eductors to reliably convey dough pellets, since 2006. Pleased with their service, they recently ordered a 6 inch sanitary eductor for a new production line. Air is supplied to the eductors from reliable, maintenance-free regenerative blowers, from Fox Valve.

One of the world’s largest manufacturers of graphite powders has been using Fox Solids Conveying Eductors to convey graphite from their grinders and screeners since 1998, with almost no wear. Their most recent order was for a 4” eductor to pneumatically transport from a large dust collector through 400 ft, to additional processing.

Back in the 1990’s, over one hundred Fox Eductors were installed at one of the largest toner plants in America – pneumatically conveying ultra-fine carbon from screeners, grinders and totes, with no fugitive dust and no blowback. In January 2022, Fox received a call to replace a 3” eductor, which had (finally) worn out. Shipped and installed in under a week.

After thorough testing with Fox venturi prototypes, Fox’s customer is now installing dozens of venturi eductors to convey dense metal powders with insert gas on their additive manufacturing products. These high performance eductors include numerous design features to meet exacting customer requirements.
