Energy-saving and environment-friendly double-rotor crushing machine

Abstract

The invention discloses an energy-saving and environment-friendly double-rotor crushing machine which is characterized by comprising an outer protection plate shell, an inner material distributor, a sieve plate supporting ring, double main shafts, crushing rods and a feeding hopper, wherein the feeding hopper is mounted at the upper end of the protection plate shell; the feeding hopper is internally provided with a baffle; the material distributor is located at the lower end position of the feeding hopper so that left and right crushing cavities uniformly supply materials; the sieve plate supporting ring is provided with a circular hole sieve plate device; and the circular hole sieve plate device is internally provided with the double main shafts. The crushing machine disclosed by the invention is improved and has the advantages that 1. the structural design is reasonable, the crushing cavities are in a gradually-opened shape and the crushing effect is increased; 2. except a feeding opening, an inner cavity is nearly a sieve plate so that the passing area of crushed materials is enlarged; the abrasion of a hammer block in an operation process and a steel sieve is reduced; and 3. a plurality of crushing rods are arranged inside the crushing machine so that when two rotors operate relatively from left to right, a hammer head (block) impacts the materials by rotating at a high speed; the materials collide and are beaten back in any direction of the cavity so as to realize a plurality of times of crushing by colliding stones by stones; and finished material products which pass through a circular hole sieve on the sieve plate are polygonal bodies, fewer materials are sheet-shaped, and the yield is high.

Description

technical field [0001] The invention relates to a crushing device, in particular to an energy-saving and environment-friendly double-rotor crusher. Background technique [0002] As we all know, crushers are widely used in bricks and tiles, cement, coal mines, mine prefabrication plants, hydropower dams, highways, bridges, various metal smelting, etc., for crushing shale, coal, coal gangue, cinder, gypsum, salt mine Carborundum stone and various brittle minerals below medium hardness have the characteristics of large crushing ratio, small and uniform particle size, high output and long life. It is an ideal crushing equipment for construction, building materials, mining and other industries. During the actual use of users, some existing crushing equipment have unreasonable structural design, low utilization efficiency, high operating costs, and affect production. Moreover, some large-scale work sites are limited, and various crushers are dusty and extremely dusty during use. ...

Problems solved by technology

During the actual use of users, some existing crushing equipment have unreasonable structural design, low utilization efficiency, high operating costs, and affect production. Moreover, some large-scale work sites are limited, and various crushers are dusty and extremely dusty during use. It is not environmentally friendly, the frequency of various failures of the crusher occurs more frequently, the upper cover is bulky, and it is extremely inconvenient to repair and replace vulnerable parts, etc.
