New Life For Worn Hammermill Screens

New Life For Worn Hammermill Screens MISCELLANEOUS EQUIPMENT Tub Grinders 12-1-25 Owners of grinder-mixer hammermills can double the life of screens by having them turned to expose a new, sharp edge. "Having them turned costs much less than buying new screens. And turned screens are good as new," says Elvin Agnew, owner of Agnew Steel & Mfg., Steele, N. Dak. Agnew, who has been in the "screen turning" business for 15 years, uses a home-made machine to invert the screen on any make or model of grinder-mixer hammer-mill. He charges $24, including freight one way (U.S. only). Most new screens cost from $40 to $150, depending on size, he points out. "As grain travels clockwise around the screen, it catches on the holes' sharp edges, than cracks and fall through the holes. If the edges are sharp, the grain goes around only once or twice. However, after time, tumbling grain dulls the hole edges and grain may have to travel around the screen four times or more before it falls through the holes," Agnew explains. "If you're getting 200 hours of grinding off one side of the screen, we can turn it for $24 and double its life. In addition to the savings in not having to buy new, there's also a considerable savings of time and fuel using sharp screens." Agnew says his screen-turning machine will handle screens up to 4 ft. wide. He notes that screens can't be planed for sharpness because they'd be too thin to endure the pressure on them.
