MODEL VR-240

For a machine that screens, mixes, aerates, and cleans molding sand, that will riddle either water or petroleum bonded sand, that can out-riddle ten men, that can be counted on for years of continuous service, look into the remarkable SWIF-MUL SPEED RIDDLE. Rugged overall construction. Frame of rigid tubular steel – inert gas welded. Rolled steel rims. Sieve screens of extra-heavy, galvanized, woven wire mesh.

Easy to operate. Positive camlock design permits rapid interchange of screens, to handle coarse, medium, or fine material. Low-maintenance, long-life engineering. Assemblies are enclosed, which gives built-in protection from dust and dirt, to drive shaft, eccentrics, and universal joints. In addition, gear box has oversized bearings and a heat-treated alloy steel drive shaft for extra-long life.
