Novel pass-type screening crusher

Abstract

The invention discloses a novel pass-type screening crusher. The novel pass-type screening crusher comprises a scraper conveyer slotted screen box body, a scraper conveyer rolling shaft type screening box body, a scraper conveyer crushing box body, a scraper conveyer driver, a scraper chain and a single roller breaking unit, when a scraper conveyer operates, and a material can enter from the tail of a scraper conveyer; mixed materials are uniformly distributed through the movement of a scraper, the qualified materials in the mixing material are preprocessed in advance, and the rest materials enter a roll screen and a slotted screen along with the movement of the scraper to be subjected to second-step processing; then the scraper can convey large materials into the single roller breaking unit, so that the unqualified large materials are crushed, the materials broken by the single roller breaking unit are reshipped or directly discharged by other equipment through a chute. The novel pass-type screening crusher provided by the invention can operate under the severe environment, the conveying capacity is high, the qualified materials are screened in advance, so that the material crushing efficiency is improved, the large materials being 1400-3000mm are transported and crushed through the single roller breaking unit, transportation, screening and crushing are performed simultaneously, the installation and the maintenance are convenient, and the novel pass-type screening crusher is widely applied on the transportation, screening and crushing operation of the large materials such as coal and metallurgy.

Description

Technical field: [0001] The invention relates to a novel through-type screening crusher, which belongs to the technical field of mining equipment. Background technique: [0002] Passing screen crusher is a new type of equipment for comprehensive mechanized coal mining face in open-pit mines. In recent years, with the large-scale mining of open-pit mines in Xinjiang, Inner Mongolia and Gansu, new requirements have been put forward for the technical performance and conveying capacity of the equipment. Open-pit mine operations mainly use explosives to explode the coal seam and then perform deep crushing and processing on the blasted coal seam. At present, the means of directly crushing the blasted large and uneven coal blocks is mainly to use double-toothed roller crushing. The limitation of the double-toothed roller crusher is that there is a certain limit on the particle size of the coal block, and the output is not easy to guarantee, and the crushed material can only be dis...
