High-Intensity +10,000 Gauss Self-Cleaning Grate Magnets Proving Effective
Press Releases / May 23, 2011
WJB Engineering has successfully installed over 100 self-cleaning grate magnets in a variety of applications including cereals, wheat, dairy powder, ingredients, flour, and rice.
The patented design allows for continuous cleaning of metal fragments from dry product such as grain and powder, using the Magnattack® RE80® Mag-Ram® Self-Cleaning system, configured to >10,000 gauss strength.
Manually cleaned grate magnets are no longer deemed suitable for many applications following the recent development of a self-cleaning grate magnet system for continuous removal of metal contamination.
In the past, most attempts made for self-cleaning grate magnets have failed as they have consisted of unhygienic sleeve designs and attempts to coordinate dual external air cylinders which inherently jam easily when introduced to dusty and harsh environments. This revolution in self-cleaning grate magnets is easily fitted into existing magnet locations from very small to very large applications, and will never have the issues mentioned above due to the single ram cleaning design – no external parts.
The 10,000 gauss self-cleaning grate magnet is configured to clean automatically, either continuously or at intervals depending on the volume of metal being collected on the grate magnet. Parameters can be set using computerized internal control systems of the company or factory in which it is installed, or by using Magnattack® stand-alone controls. The self-cleaning design allows for continuous separation of metal with no need for operators to clean the grate magnet, also making the system very useful for WHS/OSHA reasons. Special patented facilities are incorporated which compensate and minimize abrasive wear and loss of magnetic strength over time. High intensity, Magnattack® self-cleaning grate magnets are becoming the preferred option in magnetics in the food industry as they reduce risks of metal contamination caused by operator failure to clean and reduce man-hour costs of the previously time-consuming task of cleaning magnets. In addition, the industry now has a reliable, low maintenance self-cleaning grate magnet conforming to current HACCP standards.
The Mag-Ram® self-cleaning grate magnet system can be configured in full grate systems - in twin or single bar operations for conveyor discharges or small chutes.
With over 40 years’ experience in food industry magnetics, WJB Engineering can assist in design of magnetic separation equipment to suit customer’s requirements in the food industry worldwide.
