This 18-ft spiral conveyor is being used for the elevated transfer of various hot (~400ºF) catalyst extrusions coming off a rotary calciner. The heat of the material causes severe maintenance problems when using a bucket elevator, resulting in unacceptable downtime. The conveyor moves material vertically, solely through the action of twin external vibrators with no internal moving parts. It eliminates the heat-related maintenance problems of the bucket elevator with its many parts and also helps cool the material prior to the next process point. This machine is made of a 316-stainless-steel material-contact surface and includes a “high-heat” paint finish on external steel parts. A drain plug is included in the intake trough for easy washdown, which is required after each material change.

Production-Scale Mixer
The RAM 5 is a production-scale mixer based on the company’s proprietary ResonantAcoustic mixing technology that uses low-frequency, high-intensity acoustic energy to produce a consistent shear field throughout the mixing vessel, causing rapid fluidization and dispersion of material. It mixes without impellers and is capable of mixing 1 to 80 lb of material. Various combinations of gases, liquids, solids, powders, viscous liquids, and pastes can be thoroughly and consistently mixed. The noninvasive mixer is capable of mixing more 10 kg of material with viscosities greater than 100 million cp.

Large-Tube Magnetic Drawer-in Housing
The LTH (large-tube housing) increases product purity in challenging processing applications where sticking, galling, and product bridging is prevalent, such as with spices, powders, flour, starches, or pet food. It incorporates the strong 3-in.-diam Rare Earth magnetic circuit used in the company’s pneumatic inline bullet magnets into a housing for gravity/free-flow applications. The LTH maintains product flow rates by reducing product buildup and the associated downtime involved in cleaning the magnets. It also improves upon the current practice of spacing grate/tube magnets farther apart to maintain processing flow rates, which can be a dangerous application that can result in a product of questionable purity.

Particle-Size Analyzer Software
A new version of software for the Spraytec particle-size analyzer further extends the system’s data-capture and -processing capabilities. Spraytec uses the technique of laser diffraction to measure spray particle-size distributions and is widely used for the analysis of a wide range of industrial and pharmaceutical aerosols and sprays. It delivers real-time, high-speed measurements for the complete characterization of both continuous and pulsed spray events. Developed with input from existing users, the new software version makes it easier to access and understand the information required for product development and quality control. It also allows integration of the Spraytec with other spray research tools.

Adjustable Flat Air Nozzle
The 2-in., high-power super air nozzle produces a flat 2-in.-wide airstream with a strong blowing force of 2.2 lb when mounted 12 in. from the target. The adjustable force is more than three times that of ordinary air nozzles. The 2-in. nozzle uses the company’s patented technology to maximize entrained airflow while reducing noise levels. A precise amount of air is released through the 0.025-in. air gap opening that is set with a stainless-steel shim positioned between the body and removable cap. The airstream pulls in surrounding room air to produce a wide, forceful stream of high-velocity, laminar airflow. Air consumption is 37 scfm at 80 psig. The 83-dBA sound level is below the limits of the OSHA maximum allowable noise exposure standard 29 CFR 1910.95(a).
