Steel & Foundry

steelTerraSource Global is the umbrella corporation for Jeffrey Feeders as well as Gundlach Crushers and Pennsylvania Crusher. These three companies have a broad range of experience in steel mills and foundries and they have established the highest standard for design, performance and reliability with their size reduction systems and the feeders that allow them to operate at optimum levels.

Jeffrey Rader has been recognized has a champion of design and reliability whenever vibratory feeders are required. Applications include ladle additive systems, optimising the feed rates into crushers with their centre load units, blending limestone to ensure consistent kiln chemistries as well as all manner of screening and shakeout duties at foundries.

OHIO Magnetics offers a complete range of lifting magnet systems capable of handling all manner of ferrous materials. These may include; billets, slabs, plates, coils, ingots, grinding media, recycling scrap, etc. Since 1917, they have earned their reputation and are the recognized champion in the field of magnetic lifting.  

Their sister company, Stearns Magnetics compliments this offering with a comprehensive line of tramp iron removal systems which include magnetic pulleys, chute magnets, magnetic drum separators and ‘over-the-belt’ magnets with each system either protecting downstream components from damage or reclaiming valuable materials. Stearns also design and manufacture wet magnetic drum separators systems for slurry applications. An evaluation and repair facility is available and these services have kept thousands of these magnets and systems operating flawlessly for decades.

VAC-U-MAX Industrial Vacuum Cleaning Systems are considered an acceptable engineering control to support compliance with OSHA and ministry regulations. Best industrial hygiene practices recommend using HEPA Vacs to mitigate operator exposures. Explosion proof designs are specified when managing dusts that pose explosion or dust ignition hazards. VAC-U-MAX can offer vacuum cleaning systems for Class II, Division 2 environments. Applications include all manner of housekeeping tasks like trailer and railcar cleanup. Tools for wall, ceiling, rafter and equipment cleaning are available.

Macawber Engineering pioneered the use of dense-phase pneumatic conveying when asked in 1974 to convey 3” lump coal. Successful installations with a huge range of materials around the globe now number more than 6,000 and they easily facilitate the transportation of fly ash, lime, furnace minerals, foundry sands as well as coke, biomass and related biomass fuels. Knowing the difference between vacuum, dilute and dense phase conveying systems and the criteria to determine their use is critically important if your project or upgrade is to be perfect. Their Dome Valve offers an alternative to double butterfly assemblies and pinch valves over traditional valve technologies.

Getting large or complex pieces of equipment to perform exactly as designed is an absolute ‘must happen’ in this marketplace as these components are just too large to swap out or adjust in the field.
