FIELD: technique for separation of bulk materials used in mining, metallurgical and other branches of industry. ^ SUBSTANCE: jigging sieve has longitudinal L-shaped supports, elastic cards with openings on sieving surface and longitudinal sides bent at right angle and fixed with their inner surface within supports. Upper parts of longitudinal L-shaped supports are inclined from the top to the bottom. Inner surfaces of bent supports of elastic cards are provided with mating inclination from the top to the bottom and are contacting with upper parts of inclined L-shaped supports. Openings provided in elastic cards near L-shaped supports are formed above their inclined upper parts, and openings extending in direction perpendicular to supports are made longer by value equal to value of hanging above inclined upper parts of supports. Their parts hanging above inclined upper parts of supports are narrowing toward supports. ^ EFFECT: increased useful area of sieving surface and increased sieving efficiency. ^ 3 cl, 2 dwg |
