Mobile Flexible Screw Conveyors from Spiroflow

CHARLOTTE, NC -- A mobile Flexible Screw Conveyor that can be used to meter bulk ingredients and/or minor additives from storage or processes of any kind for further processing or packaging is now available from Spiroflow Systems.

The Spiroflow Mobile Flexible Screw Conveyor is ideal to use with a wide range of materials, particle sizes and bulk densities for discharging from bulk bags, silos, hoppers, transportable rigid bins, mixers, reactors or dryers in process industries such as food, chemical, plastic and others. The conveyor can be controlled volumetrically or gravimetrically from the source vessel or by ‘gain in weight’ at the receiving end.

Designed with the operator in mind, the Spiroflow Mobile Flexible Screw Conveyor is easy to maneuver by a single attendant. Locking wheels ensure stability and safety when the conveyor is in use at the various locations, parked or being cleaned elsewhere.

The system’s mobility allows use for diverse and multiple product applications in different areas of the plant. System design accommodates easy product changeovers and allows different products to be conveyed using the same system for maximum economy.

Like all Spiroflow Screw Conveyors, the mobile conveyor’s only moving part is a motor driven spiral that rotates within a sealed tube to gently move material without degradation or risk of mixed product separation. The result is a system with a low installation cost that is high in efficiency and performance.

Simple to maintain, the Ultra High Molecular Weight Polyethylene (UHMWPE) tube and steel spiral easily disassembles for cleaning to minimize downtime and reduce any risk of cross-contamination, an especially important feature when switching products. The electric motor can also be reversed to empty the conveyor of residual material and, when required, the conveyor can be flushed out with water or a cleaning solution.

To accommodate throughputs of up to 10,000 cubic feet per hour, a variety of different spiral and tube diameters are available to exactly match plant requirements.

Prater-Sterling’s new Evolution Hammermill

Bolingbrook, IL -- Prater-Sterling’s energy saving Evolution Hammermill design first prebreaks incoming material against staggered rows of cutting plate slots to reduce whole product into course mash before screen contact. The prebreak repetitive impacting produces a much finer grind through any perforation than the screen alone could produce without cutting plates.

The Evolution grinding chamber is shaped following the cutting plates, so material is initially released into a tight 3/16” hammer tip to screen clearance where acceleration is retarded to enhance grinding action.

Following this combined pre-breaking impact and close clearance accelerated grinding, at 900 of circumference the shaped chamber straightens to open hammer tip to screen clearance to 7/16” and significantly improve finished particle egress out of rotation.

Compared to any conventional hammermill designs, the Evolution’s prebreak and close clearance enhanced grinding action replicates particle distributions though up to two larger perforation sizes.

Competitors require one horsepower to achieve capacity, while Prater-Sterling achieves that capacity with 15% to 20% less HP. For a finished particle distribution of 85% minus 14 mesh, 80% plus 60 mesh grinding #2 yellow dent corn at 12% to 14% moisture, most US ethanol plants are designed around 35 TPH (31.75 MTPH) of capacity per hammermill. To meet that specification and capacity a conventional 38” diameter hammermill use 1/8” (3.17 mm) Perf screens and 250 HP 1,800 RPM drive motors.

The Prater-Sterling 40” diameter Evolution Hammermill can replicate that particle distribution through 3/16” (4.76 mm) Perf screens with a 200 HP 1,800 RPM drive. On a 24 hour, 7 day/week operating schedule at the lowest kW cost, that 50 HP savings is worth over $20K annually per hammermill.

Mr. Stephenson needs help with a labyrinth seal:

We have an air classifier labyrinth seal that does not work correctly. Powder leaks into the seal area and binds the machine.

Wheel size is 400 mm diameter and it has 3 ribs to act as the labyrinth. Clearance in between the faces is 0.3 mm.

We would like to know what is important in getting a very good seal. Pressure across the wheel in up to 6 " Wg.  (to post reply, click here)

Mr. Saleh has a problem with particle size measurement:

Can any one help? What does it mean if the material has 90% through 200 mesh? How is that related to the particle's size in microns? Where can I find the conversion tables if any?  (to post reply, click here)
