Profile: Gilson Co., Inc. manufactures and distributes material testing equipment. We deal with asphalt, aggregates, cement and mortar, concrete, crushing, pulverizing, lab essentials, milling & grinding, ovens, furnaces, scales, balances, screening, sieves, sieve shakers, soils, splitting & sampling, & thermometers. Our TS-1 Gilson testing screen is ideal for particle size determinations on large samples of aggregate, slag, ores and other coarse materials. Batch sizes up to one cubic foot (0.028 m3) or more can be processed into six fractions in as little as three to five minutes, depending on material type. Vibration and amplitude characteristics are fixed at optimum for mineral aggregates in the 4 inches (101 mm) to No.4 (4.75 mm) size range, but options and accessories are available to optimize machine performance when testing finer samples or special materials. The standard testing screen can be used to process material all the way down to No.200, if less efficient separations are acceptable.
