| 主权项 | 1. A hopper structure for treating granular material, comprising an inner sidewall section arranged, in use, as an upper tubular sidewall, a tapered lower section having a delivery mouth and an elongated insert body wherein said insert body comprises an upper portion and a lower portion arranged at said lower tapered portion of the hopper and having its conicity facing away from said upper portion, said upper portion axially extending from the base of the lower portion up to at least one half of the upper tubular section at an angle λ≧0 with respect to a vertical line, wherein said lower portion of the insert body is made of a material having a friction coefficient with respect to granular material, greater than the inner sidewall friction coefficient with respect to granular material. | ||
