External type cylindrical residue isolating screen

Abstract

The invention discloses an external type cylindrical residue isolating screen which comprises a machine frame, a screen cylinder rotationally installed on the machine frame and a rotary driving assembly installed on the machine frame and used for driving the screen cylinder to rotate. A feeding assembly used for feeding materials to be screened to the outer surface of the upper portion of the screen cylinder is arranged above the screen cylinder. A receiving assembly used for collecting screened materials and guiding out the screened materials is arranged in the screen cylinder. A residue removing assembly used for removing unscreened materials attached to the outer surface of the screen cylinder is arranged outside the screen cylinder. The external type cylindrical residue isolating screen has the advantages of being simple and compact in structure, easy to manufacture, convenient to assemble and maintain, capable of reducing the labor intensity, saving the labor cost, improving the screening efficiency and ensuing production continuity and the like.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to an external-entry cylindrical slag separation screen. Background technique [0002] Explosives are used in mine mining. After the explosion of explosives, many plastic tubes and plastic skins produced by the explosion of the packaging shell and nonel will remain in the ore. When the ore enters the mineral processing plant for mineral processing, these plastic products are not easy to be destroyed. Grinding will not only affect the grinding efficiency due to continuous circulation in the grinding and grading process, but also will absorb a large amount of flotation chemicals when the finely ground and classified plastic fragments enter the flotation process, and will also pollute the concentrate and affect the flotation process. Choose efficiency. [0003] Plastics are less dense than pulp, so they can be screened out in the classifier overflow. However, bec...

Problems solved by technology

However, because the plastic products after grinding have a large number of filaments around them, these filaments are like tentacles, which can easily trap the plastic products in the screen. In addition, the plastic products themselves have certain elasticity and are easy to be stuck in the screen holes. , leading to extremely poor fluidity of plastic products on the screen, and causing blockage of the screen holes, which must be cleaned manually frequently, which has problems such as high labor intensity, high cost, and inability to continue production.
