Problems solved by technology

Jaw crushers and hammer crushers are the most used among them. Although these crushers have played a good crushing role, there are also some problems in use. Most crushers can only perform crushing operations, and sometimes the crushing is not ideal. , and secondary crushing is required, and the crushed coals are large and small, so they cannot be screened and classified. In addition, most of the crushers have serious noise pollution, which makes it difficult for underground workers to communicate. Some problems need to be improved.

Abstract

The invention relates to a noise prevention multi-grain-size screening crusher. The noise prevention multi-grain-size screening crusher comprises a crushing box, sound insulation cotton, crushing hammers, a rotating shaft, a first-level screening device and a second-level screening device. The noise prevention multi-grain-size screening crusher is characterized in that a feeding port is formed in the upper portion of a box body of the crushing box, a discharging port is formed in the lower portion of the box body of the crushing box, and the rotating shaft is arranged at the middle portion of the crushing box and provided with at least three crushing hammers; and the outer side of the crushing box is wrapped by one layer of sound insulation cotton, the first-level screening device is arranged below the discharging port of the crushing box, and the second-level screening device is arranged below the first-level crushing device. The noise prevention multi-grain-size screening crusher insulates sound and prevents noise, classified screening can be conducted after crushing, the structure is simple, and multiple purposes are achieved.

Description

technical field [0001] The invention belongs to the technical field of crushers for coal mines, and in particular relates to a noise-proof multi-particle size screening crusher. Background technique [0002] With the modernization of the coal industry, major changes have taken place in the coal mining process, and the top-coal caving process has been scientifically applied and developed. When the hardness of the coal is f2, the strength of the coal is not easy to be damaged, and the caving coal is easy to form lumps. When the working face encounters a fault, the number of lumpy rocks increases, and lumpy coal and lumpy rocks are not easy to pass through the loader or loader. Points, and damage to transportation equipment in the form of bumping, bumping, smashing, etc., will bring difficulties to safe transportation underground. Crusher is to fully crush lumpy coal and massive rock so that it can pass through the reloading machine or reloading point smoothly to ensure safe t...
