PREVENTION DEVICE AGGREGATE SCREEN NET FOR ROTATIOR TYPE DRUM AGGREGATE SORTING

摘要

A blocking prevention device for a screen net of a rotary drum type aggregate sorter is provided to prevent an aggregate discharging port from being blocked up while sorting aggregates, by shaking and swinging rubber screens in different forms at each position. A blocking prevention device for a screen net of a rotary drum type aggregate sorter is composed of: a unit for receiving aggregates of the crushed construction wastes; a drum turned at the constant speed by a power body, in order to sort out aggregates supplied from the unit; a rubber screen(20) installed in the drum and provided with aggregate discharging holes bored in the shape of a perforated net; the power body and a power transmitting unit rotating the drum; and a discharging unit separating and transferring aggregates that are sorted and un-sorted in the drum. The rubber screen installed at the inner periphery of a circular rod(10) is divided into plural parts. The rubber screens are settled by fixing rods(12) while coming into contact with the inner periphery of the circular rod at each divided spot. The rubber screen between the fixing rods is separated from the inner periphery of the circular rod and protruded.
