Thermoplastic pressure regulators are introduced
The Series PRA (photo) is a pneumatically controlled pressure regulator, also called a pressure-reducing valve, that maintains a constant downstream pressure from 5 to 125 psi with high accuracy over varying flowrates. The new design uses compressed air and two rolling diaphragms to control liquid pressure with greater accuracy than spring-loaded regulators. Suitable for highly corrosive and ultra-pure chemicals, the PRA will routinely handle inlet pressures of up to 150 psi. The regulator’s design features two opposing large-area frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms and air pressure is applied to the other. Because the air pressure can be maintained with more accuracy than the force provided by a spring, the PRA offers greater sensitivity and less variance from set pressure than previously available thermoplastic regulators. — Plast-O-Matic Valves, Inc., Cedar Grove, N.J.

Screening is made simple with this combined system
This 3-in-1 system combines a Vibroscreen vibratory screener (photo), a batch hopper and an integral feed-control device that regulates the flow of material into the screener. The feed-control device consists of a circular disc positioned below the flexible connector at the screener’s inlet, perpendicular to the flow of material. The diameter of the disc is smaller than the inside diameter of the inlet, forming an annular gap through which material can pass. Because the disc vibrates with the screener lid to which it is affixed, the flow of material through the gap remains uniform. Interchangeable discs in a range of diameters are provided to achieve various feedrates. Feed-control devices for the Vibroscreen units range in diameter from 18 to 40 in. and are offered with single- or multiple-screening decks that separate particles in one to five sizes from 2 in. to 500 mesh (25 µm). — Kason Corp., Millburn, N.J.

With this device, service technicians can hear sounds that signify problems, such as: compressed-air leaks; electrical discharge; vacuum, natural gas, propane, refrigerant, and seal and gasket leaks. The Marksman uses a two-tiered process to ensure accurate diagnosis. First the receiver unit converts inaudible sound into audible sound using a process called heterodyning. The receiver’s Sound Signal Technology then fine tunes the audible sound into the natural sound emitted by the defect itself. An LED display indicates the intensity of incoming signals from the problem source to ensure error-free diagnosis. — Spectronics Corp., Westbury, N.Y.
Laser-markable tubing allows for easy field identification
Fluoroplastic heat-shrinkable tubing (photo) is often used to splice together cabling or encapsulate wiring. Now, laser marking allows for easy identification in the field. Laser marking is a non-contaminating, indelible mark used for parts identification or enhancing traceability. The marks are virtually unremovable, and may include part numbers, text, bar codes or logos. In the past, marking was unheard of on fluoroplastic tubing, as traditional inks would not adhere to the fluoroplastic. Lasers can achieve a pigment deviation in the material, creating a visible mark on the product without adding ink or other contaminants to the product. — Parker/Texmed div. of Parflex, Ft. Worth, Tex.

This solids flowmeter uses microwaves
The microwave solids flow detector Model SFD-2 (photo) is a non-invasive detector that has recently proven itself in the monitoring of coal at a coal-fired plant in India. The device uses Doppler radar technology to monitor the flow of bulk solids and powders in chutes and pipelines. For the Indian application, the device provides relay contact outputs in response to the presence or absence of coal flow in the feeder lines; this is used to detect coal flow backup or equipment malfunction to provide feedback to a control system. — Monitor Technologies LLC, Elburn, Ill.
These static mixers combine turbulent and laminar flow
“Mikromakro” describes the combination of static-mixing elements of different geometries and diameters. Uniform pre-distribution is achieved in the makro mixer, while the best possible homogenization is achieved at the molecular scale in the micro mixer. With the patented combination of turbulent and laminar flow, it is possible to cope with high (>1,000) aspect ratios in viscosities, and to solve difficult mixing tasks with an additive flowrate of less than 1% in the main stream. CSE-X mixing elements in mikromakro combination are mainly used for processing of plastics. — Fluitec Georg AG, Neftenbach, Switzerland

Modular construction enables units to be configured for match specific tasks; about 100 different configurations are possible. The grinders have a maximum output of up to 100 m3/h, and handle grain sizes of up to 300 mm, producing particle sizes (without a screen insert) of less than 20 mm (single shaft) or below 12 mm (two shaft). Product temperatures of up to 400°C can be processed. — Telschig Verfahrenstechnik GmbH, Murrhardt, Germany
When pressed for contamination-free compaction
Rolls of the Kompaktor (photo) press have been machined with a hard coating, enabling them to process fine-dispersed bulk materials into flakes or briquettes with an increased density. Even abrasive and corrosive materials can be handled, without contamination caused by metals. Roller compaction is a dry, dust-free process with low energy consumption and low product heating. — Hosokawa Bepex GmbH, Leingarten, Germany
Fill a lot of drums with this unit
Equipped with a 12 x 36-in., twin-motor, vibratory screener feeder, this firm’s latest drum-filling system (photo) is designed to deliver 2,500 lb/h of bulk chemical material. The system’s 20-mesh scalping screen removes foreign products and oversize agglomerates, and a permanent plate magnet in the product outlet chute prevents ferrous material from entering the drum. — B.E.S.T., Inc., Brunswick, Ohio
Enhanced versatility with two mills, one head
The inlet diameter of the new ConiWitt conical sieving mill is available as DN 150, 200 (photo) and 250. The milling head is interchangeable between the smallest and the medium-sized mill; this means the same motor/arm setup can be used in all situations. The ConiWitt mills are also easy to clean and, after removing the rotor and sieve, the entire milling head is easily sterilized in an autoclave. — Frewitt S.A., Fribourg, Switzerland
Prevent wet solids from clogging with this feeder
When wet coal is prevalent, ordinary feeders often become clogged, causing pluggage and inadequate flow to the pulverizer; this causes fluctuations in boiler heat rate, sometimes requiring the boiler to come off line until the problem is corrected. The Posimetric Feeder (photo) can eliminate these costly no-coal-flow events, says the manufacturer. The feeder handles materials with a wide range of characteristics, including wet, dry, lumpy, sticky, abrasive or granular. — Pennsylvania Crusher Corp., Broomall, Pa.

The unit has been designed to operate the centrifuge with the same filter-cake thickness as on a production unit; this results in exact scale up results for all process steps of filling, spinning washing and discharging. Maximum flexibility is achieved for frequent product changeover, fast startup, automated cleaning and quick inspection. — Heinkel Filtering Systems, Inc., Swedesboro, N.J.
Forced feeding increases capacity of compact mills
The SB Series granulators are suitable for recycling PET bottles as well as for use as secondary granulators where shredders cannot achieve the required granular size. For example, an SML 60/100 SB, with 600 X 1,000-mm rotor and 75-kW drive, can reach a throughput of 3,400 kg/h with a screen size of 8 mm. New in the product range is the SML 45/60 granulator, which can achieve a throughput of 1,000 to 1,200 kg/h when grinding PET bottles (12 mm screen). Such capacities are possible in these compact machines because of the forced-feeding device. — Herbold Meckesheim GmbH, Meckesheim, Germany
