Chemical ElectroPhysics Co. Inc. rolled out its Rheoceptor viscometer and a new smaller version of its ceramic ring sensor, the Proceptor.
The company in Hockessin, Del., presented technical papers on both innovations.
Chemical ElectroPhysics said the Rheoceptor is an in-line viscometer that can be built into rotating equipment, such as gear pumps and extruders. It uses a cam and a flush-mounted pressure transducer. A pressure increase is recorded as the cam passes the pressure transducer, and is used to measure the viscosity.
The gap and speed of the cam control the shear rate of the measurement.
The Proceptor, first introduced three years ago, now comes in a model with a small inside diameter of one-half inch.
It measures concentrations of ingredients in fluid mixtures, as the mixture flows through the ring. Measurements include dielectric constant and the electrical conductivity.
Wayne introduces MicroBatch system
Wayne Machine & Die Co. of Totowa, N.J., announced a Micro-Batch compounding/pelletizing system, designed to process small batches of research- and engineering-grade materials.
Wayne Machine claims the 1-inch strand pelletizer boasts a design in which both sides of the unit are supported. Typically, the company said, lab pelletizers are supported on just one side, or cantilevered. Support on both sides helps avoid strand slipping, enhances bearing life by reducing stress on the shafts and bearings that can be caused by engineering resins.
A micro-pellet option allows continuously variable pellet length from 0.010-inch to 1/8-inch with a simple adjustment.
B&P Process unveils its smallest kneader
B&P Process Equipment and Systems LLC of Saginaw, Mich., introduced the smallest size of its continuous kneaders, a laboratory model with a screw measuring 30 millimeters in diameter.
The CK line ranges from 30-220mm.
Jack Kubica, director of sales and marketing, said B&P has been a major player in large-size kneaders used to make shear-sensitive materials such as powder coatings and toners. B&P has been moving down in size to smaller machines, such as the CK-30, he said in an interview at the company's Antec booth.
A modular design on the CK-30, with segmented barrel and screw, allows for downstream feeding, liquid injection and vacuum venting. The kneader is coupled to a 40-mm discharge extruder equipped with a strand die for making pellets.
At NPE in June, B&P will unveil both the CK and the CKS line of continuous kneaders.
