New Quantum Series 3-Way Wye Line Diverters

SALINA, KS - The global leader in valve solutions, Vortex® Valves North America - a division of Salina Vortex Corporation - introduces its new, patent-pending, Quantum Series 3-Way Wye Line Diverter specifically engineered to handle dry bulk solids in pneumatic conveying systems with vacuum or positive pressures up to 15 PSIG (1 barg).

The Quantum Series 3-Way Wye Line Diverter, available in 2" to 8" (50mm to 200mm) pipe or tube, can direct dry bulk material from one source to three destinations, or converge from three sources to one destination.

Vortex utilizes precision laser cutting and bending technology to manufacture this leading-edge diverter valve. It provides a number of advantages over traditional flapper and rotating tunnel style diverters and eliminates trouble spots inherent in these conventional diverters. The wye line diverter provides superior sealing, low installation weight, fast "in-line" maintenance, and long-term, reliable service.

The Quantum Series Wye Line Diverter provides positive shutoff of air and material improving process efficiency, minimizes cross contamination, and eliminates material buildup beyond the closed port. Adapting the Vortex Quantum Series Wye Line Diverter to meet system requirements is made easy with a wide selection of actuators, position indication switches, flanges, and tube stubs.

The Quantum Series 3-Way Wye Line Diverter also offers a wide variety of modifications to accommodate high or low temperatures, corrosive, humid, and hazardous environments. Contact Vortex for application specific information.

For more than 30 years, Vortex has provided quality Slide Gates, Diverters, and Iris Valves designed specifically for handling dry bulk solids in gravity, vacuum, dilute, or dense phase applications. Vortex Valves are engineered for dependability, durability, easy maintenance, and offer proven solutions to material handling and process efficiency problems. With an in-house team of engineers, Vortex Valves can be completely customized for individual applications or special installations.

Ultra-High Capacity Twin Centrifugal Screener

MILLBURN, NJ -- A new Centri-Sifter® Twin Ultra-High Capacity Centrifugal Screener introduced by Kason Corp. matches the capacity of two individual High Capacity screeners within a smaller footprint, while cantilevered three-bearing shafts allow rapid sanitizing, according to Henry Alamzad, president.

Dry or moist bulk solid material is gravity-fed through a feed splitter to evenly divide the flow of incoming feed material into the two horizontally-oriented cylindrical screening chambers which operate in parallel. A shaft in each screening chamber rotates a helical paddle assembly that accelerates the radial movement of particles against the screen.

On-size particles pass through apertures in the screens and fall through a cone-shaped discharge chute, while oversize particles are propelled through the open end of the screen cylinders and ejected through a discharge spout.

Each of the screening chambers features a sliding end cover and three-bearing shaft that cantilevers for quick removal of internal components.

External roller bearings are located at the motor end of the shaft and on a sliding cover at the discharge end for maximum support and vibration-free operation. When the end cover is hinged open, the shaft becomes a cantilever supported by a third externally-mounted roller bearing located between the motor-end bearing and material feed point, allowing internal components to slide freely from the opposite shaft end for thorough wash-down.

In addition to sifting and scalping of dry bulk materials, the screener can break up soft agglomerates and/or dewater moist solids or slurries.

The screener is constructed of stainless steel finished to 3-A, FDA, BISSC, and other sanitary standards required for food, dairy, and pharmaceutical applications, as well as contamination-sensitive chemicals.

The company also manufactures other types and sizes of centrifugal screeners as well as circular vibratory screeners and fluid bed dryers, coolers and moisturizers.

Mr. Moorlach wants help with blow-through rotary valve:

I have a dust collector (Airjet Filter) with a blow-through rotary valve.

Now I have a bit of a problem, the product is something you find in a vacuum cleaner (so called Hoover Vac) and is building up above this rotary valve because the pressure underneath the rotary valve is positive and in the filter it is negative.

What would one of your guys think is the best solution to prevent this problem?

A pneumatic vacuum lift is no option the product has to be transported via a pressure line.  Any suggestions?  (to post reply, click here)

Thanks,

Mr. Castano needs to calculate material pressure on walls:

We are helping a client who's designing a large concrete silo for clinker, but the containing walls of this silo are not vertical. The cross section of the silo is approximately 3/4ths of a circle, making the silo also the majority of a sphere.

The usual formulas to calculate material pressures and material friction on the silo walls apply to vertical walls.

Do you know of any references we can use to estimate the bulk material normal pressures and shearing friction that he should consider on the inclined walls of this silo?  (to post reply, click here)

Thanks in advance,
