Screening, Classifying, & Separation

Circular Unitized Gyratory Screen
The Vibroscreen is a circular unitized gyratory screen with three-component multi-plane mechanical vibration. The motion is through a motor with a double extended shaft, fitted at both ends with eccentric weights. The whole drive assembly is mounted on a circular base by rugged springs that allow the unit to vibrate freely, and at the same time, the springs prevent transmitted vibration from reaching the floor area on which the machine stands. Screens can be mounted one on top of the other within the screening assembly. (Pennwalt LTD) Heinkel USA, Swedesboro, NJ 856-467-3399 www.heinkelusa.com

High-Capacity Vibratory Classifier
A new Vibroscreen high-capacity, two-deck classifier separates up to 70 tn/hr of bulk solids into three fractions. Measuring 100 in. in diameter, it classifies bulk chemicals, minerals, plastics, foods, dairy products, pharmaceuticals, and other materials ranging from dry bulk solids to solids-laden slurries. Quick-disconnect clamps between each screen frame provide rapid interior access for inspection, screen changes, and wash down. An optional Air-Lift device pneumatically raises any of the screen frames, enabling one operator to rapidly perform what was previously a two-person task.

Grate Magnets
Booth 557 - The EZ-Clean drawer magnet eliminates the time-consuming and tedious process of manually removing collected metal. Cleaning is now easily accomplished by pulling the magnetic drawer of grate tubes through stationary outbound wiper seals. Collected metal falls into a catch pan located outside of the product stream for disposal. These magnetic grates can be finished to customer requirements and retrofitted to existing bag dump stations. The food-grade, Class 1 rare earth magnetic grate removes fines from blended ingredients used in the food industry. The grate magnet is designed to sit inside an existing hopper with the angles on the four corners supporting the grate as well as to allow the product to slide towards the magnetic tubes, eliminating the chance that product gets past the magnet. The diverter in the center helps divert the product towards the tubes and adds strength to the structure. Industrial Magnetics Inc., Boyne City, MI 888-582-0821 www.magnetics.com

Vertical Shaft Classifier
The model MCS-800 classifier has a nominal air flow of 48,000 cfm and can be designed to suit a variety of material applications and product rates. Airflow and particle behavior are predicted using state-of-the-art finite element-based flow modeling software and empirically verified through on-site laboratory and pilot plant testing. The feed material can be introduced pre-dispersed in an airstream or mechanically fed into the classifier. The airstream can be recycled to the classifier in closed-circuit operation or filtered and discharged to atmosphere in open-circuit operation. The cut point of the fine product can be precisely controlled by varying the rotational speed of the classifier blades. RSG Inc., Sylacauga, AL 256-378-3836 www.airclassify.com
