NIR-based technique provides a simpler way to measure moisture

moisture measurement

Kett US

This company has developed an approach to moisture measurement that uses Near-Infrared (NIR) light, which can deliver immediate, laboratory-quality moisture readings. Traditional laboratory and online moisture-measurement techniques — while capable of providing comprehensive results — lack the simplicity and flexibility for frequent spot checks, so secondary testing methods are often needed. The new NIR-based method enables portable, instant moisture readings of chemical feedstock, product formulations or any end product. NIR moisture meters allow accurate measurement of solids, pastes, and liquids without contact or sample preparation, so there is no contamination in handheld and online models, says the company. Because no direct contact or sample alteration is required, particle size variation and unusual textures are not an issue.  In addition, because the process is non-destructive, samples remain unaltered so they can be used for additional tests or put back into the product stream. Unlike complex laboratory equipment, portable NIR equipment, such as the KJT130 Handheld Portable Instant Moisture Meter,  are designed for ease of use — the user simply points the instrument at the product and the moisture content is instantly shown on a digital display, with results accurate to .01% in a 0-100% measurement range.— Kett US, Anaheim, Calif.

This unit combines impact grinding and air classification

Kason

Kason

The model CAM 1300 air classifier mill (photo) combines impact grinding and air classification in one machine to produce fine powders with narrow particle-size distribution, at throughput rates up to 16.5 ton/hour. Intended for bulk foods, pharmaceuticals, chemicals, epoxy resins, powder coatings and mineral applications, the mill allows control of the air flowrate and grinding temperature to condition heat-sensitive or hygroscopic materials. Material enters the milling chamber where a spinning rotor impacts the particles against grinding segments inside of the chamber wall by centrifugal force. A rising column of air lifts the particles into the rotating classifier wheel, separating on-size material and directing it to the process air stream for collection or further processing. Over-size material returns by gravity into the path of the spinning rotor for further grinding. Particle size is readily controlled by varying the rotor speed, classifier speed, air flowrate and feedrate, eliminating the need for separate classification equipment. — Kason Corp., Millburn, N.J.

New low-noise fans are oil-free to prevent contamination risks

Rite-Hite

Rite-Hite

The new Direct Drive high-volume, low-speed (HVLS) fan (photo) produces no noise and uses no oil. The lack of gears reduces noise, while the absence of oil means the Direct Drive HVLS fan eliminates any opportunity for contamination. The fan comes standard with 24-ft dia. blades, but 20-, 16-, 12- and 8-ft dia. options are also available. A single Direct Drive HVLS fan can circulate a large volume of air up to 85 ft from the fan’s center in all directions for optimal heating or cooling of an area encompassing up to 22,000 ft 2. The unique design of the fan directs air outward from the center in a conical shape, eliminating dead-air holes directly beneath the fan and in corners, translating to more uniform airflow from floor to ceiling and from wall to wall. Without a gear motor, the Direct Drive HVLS fan can be installed in roughly half the time it takes to install a traditional HVLS gear-motored fan, says the company. — Rite-Hite Corp., Milwaukee, Wis.

New thermowells reduce vibration and fatigue

Emerson

Emerson

The Rosemount Twisted Square thermowell (photo) is said to reduce dynamic stress, simplify process calculations and provide more accurate temperature measurements than other thermowells on the market. Twisted Square thermowells improve reliability and reduce risk of fatigue failure through their ability to dampen dynamic stresses caused by oscillating vortex pressures. These dynamic stresses can result in vortex-induced vibration (VIV), which is the primary source of thermowell stress failures. The new design is said to reduce VIV by over 90%. This helps to simplify process calculations by eliminating the need to size thermowells to reduce dynamic and frequency limits, thereby saving engineering time and lowering costs without requiring design changes. It is suitable for use where conventional thermowells fail to meet the ASME PTC 19.3 TW standard for safe and reliable thermowell design. — Emerson, St. Louis, Mo.

BelGAS FM flame arrestors (photo) stop ignited vapors from traveling backward into a vent line or tank, preventing explosions, burns and other hazards. The flame arrestor product line includes critical safety equipment, such as burner arrestors, inline arrestors, stack arrestors and vent arrestors. A key differentiator of these flame arrestors is a faceplate with a pressed and sealed sight glass, rather than one that is welded or held in place with a lock nut. This eliminates seams and gaps, reduces the chance of leaks and better withstands equipment vibration. — Marsh Bellofram Group of Companies, Newell, W. Va.
