Abstract

The invention discloses a material mass crushing machine which comprises an explosion-proof motor, a rotating shaft, a bracket, a cutting roller, a feed bin, a strip roller, a discharge bin, a transmission gear and a coupling, wherein the cutting roller meshes with the strip roller; a strip tooth longitudinal section of the strip roller is triangular or tapered; and a cutting tooth longitudinal section of the cutting roller is square. According to the material mass crushing machine, inflammable, explosive, high-plasticity and irregular lumps of which the side lengths are from 100 mm to 400 mm can be made into small-mass materials of which the side lengths are smaller than or equal to 50 mm through rolling cutting and rolling pulling, a motor accelerator and a motor reducer are adopted for power transmission, on-site electrical equipment adopts explosion prevention of the same grade, and the material mass crushing machine is a full-mechanical rolling type crushing machine of which the production capacity is 40 kg / min.

Description

technical field [0001] The invention belongs to the field of mechanical crushing, and in particular relates to a lump breaker, which mechanically crushes plastic bulky lumps of materials with special chemical composition characteristics of mixed ester propellants after gelling (kneading). Background technique [0002] The existing structure of the crusher adopts collar type, rotary knife type or nail roller type, and is mainly used for crushing hard, brittle and non-flammable and explosive materials. Such as: crushing of ores, brittle metals, and large crystals. At present, there is no crushing equipment for plastic, flammable and explosive materials and other forms of mechanical equipment. Cutting plastic materials into lumps of different side lengths required by the process requires high labor intensity, low production efficiency, prominent safety risks, and toxic solvents in the materials can seriously damage the human body. Contents of the invention [0003] The purpo...
