Double-rotor type sieve-free wet gangue crusher

Abstract

The invention discloses a double-rotor type sieve-free wet gangue crusher. An upper single-rotor type gangue crusher and a lower single-rotor type gangue crusher are arranged on an underframe of the double-rotor type sieve-free wet gangue crusher, shells of the upper single-rotor type gangue crusher and the lower single-rotor type gangue crusher are connected integrally, a discharge opening of the upper single-rotor type gangue crusher is directly used as a feed opening of the lower single-rotor type gangue crusher, a discharge opening of the lower single-rotor type gangue crusher is a straight-through type bottom opening, and the upper single-rotor type gangue crusher is diagonally located above the lower single-rotor type gangue crusher. Double-rotor type upper and lower crushing is adopted, so that a crushing effect is good, and filling ability is high. A screen grate at the bottom in the double-rotor type sieve-free wet gangue crusher is omitted, high-humidity materials are directly discharged via the discharge opening, and blockage is stopped. A wear-resistant combined hammer is adopted, when the hammer needs to be replaced, only a hammer head is replaced, but a hammer handle is not replaced, after being abraded, the hammer head does not need to be repaired, but can be used again by means of shifting, the service life of the hammer is three times longer than that of a common hammer, accordingly, capital investment is saved, and an economic benefit is increased.

Description

technical field [0001] The invention relates to a gangue crusher. Background technique [0002] In coal mine gangue filling system, the commonly used gangue crusher is a single-rotor type, which is composed of a casing and a rotor inside the casing. There is a screen bar at the discharge port and is driven by a motor. If the wet gangue has a high viscosity when crushing, it is difficult to discharge the broken gangue through the sieve bar, and most of the broken gangue remains in the crusher, which reduces the work efficiency. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing single-shaft crusher, the present invention provides a double-shaft wet gangue crusher capable of crushing high-humidity coal gangue. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: it is provided with an upper and lower two-stage single-rotor type gangue crusher on a bottom frame, the sh...
