Marion, IA -- The Vector Wurster Coating Accelerator System has been developed to improve the performance of a standard Wurster column. The Wurster Coating Accelerator system controls the movement of the product/particles into the coating spray zone, positioning it in the optimum location of the atomized spray to improve the coating quality and uniformity.

A pneumatic particle diverter that utilizes adjustable air-pressure is used to control the movement of the product and to position it above the spray gun nozzle, into an enlarged fully atomized spray zone area. The particle diverter is a sleeve device, with an arrangement of strategically located diverter holes, which surrounds the shaft of the Wurster coating accelerator spray gun. The accelerator spray gun has an enlarged orifice allowing for increased solution spray rates and proper atomization of the solution.

Vector Corporation is a pioneer of continuous tablet coating systems. Drawing upon our years of expertise of the batch tablet coating process, Vector has applied the scientific batch processing knowledge to the process of continuous tablet coating. They offer a variety of continuous tablet coating systems to meet the specific needs of customers. Different market requirements for the continuous coating of tablets have lead to the development of multiple continuous coating systems.

Lisle, IL -- Alstom Power, Inc. received an order from Graymont Western USA for the supply of a new generation hybrid turbine classifier which was installed on a Raymond 533RB Bowl Mill supplying a fuel mixture of pulverized coal and petroleum coke to a lime kiln at Graymont's Montana plant.

The new Raymond Hybrid Turbine Classifier incorporates the use of an updated static classifier around the periphery of the innovative turbine rotor. The static classifier pre-classifies pulverized coal exiting the grinding zone of the bowl mill, eliminating the coarse fraction prior to it interfering with the final classification process that is the function of the turbine.

The result with the hybrid classifier was that the bowl mill delivers pulverized coal and petroleum coke having a fineness of 95% passing 200 mesh. The unit has achieved the desired fineness and has also demonstrated that it is capable of delivering particle size distributions containing only a trace amount standing on a 100-mesh screen.

The Graymont's bowl mill equipped with this hybrid classifier design consistently produces solid fuel possessing particle size distributions compatible with today's combustion technology, which strives to achieve improved flame characteristics while reducing emissions and minimizing unburned carbon.

The Raymond Hybrid Turbine Classifier is available for all types and sizes of new or existing Raymond Bowl Mills and the design can also be extrapolated for use with other manufacturers' pulverizers.  Alstom Power Inc.- Air Preheater Company (APC) is the leading supplier of engineered products, services and technologies for heat recovery systems, size reduction and classification equipment thermal processing and incineration equipment, gypsum wallboard manufacturing equipment and custom manufacturing applications.

Charlotte, NC -- Who would have ever though such a simple idea would save operators time and money?  North Carolina-based Gough Econ developed and offers "textured-surface" replacement buckets to improve the release of sticky product that normally would remain in the bucket.

The injection molded buckets have raised, inside pattern decreases surface contact and tension, minimizing the coefficient of friction, allowing easier product release from the bucket. The texture also increases strength and rigidity of the bucket, improves impact characteristics and longer life with abrasive products.

Buckets available for 9” and 18” “S” Series Swinglink bucket elevators. They are made in FDA-approved white polypropylene or glass filled white polypropylene and heat resistant Nylon 66.

Gough specializes in the design and manufacturing of material handling systems.  Gough’s test center enables customers to test their product on proposed equipment before recommendation and after the sale to insure the highest level of quality and reliability. By working closely with customer process technicians and operating personnel, Gough has quietly built a reputation for innovation and reliability.

The new X-Series Generator being offered by Charles Ross and Son Company produces sub-micron emulsions in less time and at less cost than conventional high pressure homogenizers.

The X-Series design is proving to be a superior alternative to costly homogenizers. Production rates are high, for example when Ross X-Series generator is included in a machine it can manufacture at a rate of between 10 and 75 gpm. When combined with positive displacement pumps the mixers can be pushed to even higher limits.

The X-Series Rotor-Stator Generator is a patented design. Since the mixer that includes this generator does not have fast wearing impingement plates maintenance is kept to a minimum. The X-Series mixer depends on high shear rates that are generated by a close tolerance multi-rowed rotor/stator turning at high speeds. These machines typically operate at tip speeds up to 17,000 feet per minute.

Ross manufactures X-Series Mixers in 10 through 250 hp models in standard industrial and sanitary designs. All wetted parts are constructed of type 316 stainless steel and include mechanical seals to meet the needs of the application for which it will be used.

Ross equipment is the first choice for mixers, blenders, dryers and dispersion equipment. The company has a world class reputation for innovative engineering, superb construction and fast delivery. Ross equipment is manufactured on five continents. In the USA alone, we operate five plants and a vigorous R & D program.

Mr. Rawlins needs a "break sensor" for conveying line:

We are interested in sensors that would detect a break in a conveying line carrying flour and loss of product into the surrounding environment.

The detection system must meet fire code specifications in the state of California.

Please forward any information or recommendations to us.

Osvy needs help with a gas-tight screw conveyor:

We are in charge of the operation of a solvent extraction plant for soybeans.  We have a big belt type extractor and at have at the end a screw conveyor that allows the extracted material to feed a chain conveyor.

This screw conveyor receive the material at the full length from the belt of the extractor and have two points of discharge: one at the end of the screw and the other in the middle.

The matter is that twice a year we must to clean out clogged material between the flights because the defatted meal stick against the faces and shaft of the screw.

Material: temperature = 61 deg ºC
Characteristics = granular embedded with hexane, moisture of 10 %.
Flow : 280 metric tons/hour
Screw: material of construction: mild carbon steel
Type: variable pitch
Diameter: 980 mm
Total length : 7.5 meters
Power: 75 HP Consumption: 50% full charge
RPM : 35
 
Please, can you give me and advise how to control this problem because we need to stop the whole plant and to clean this device with difficulties?
