Description

Crushing and screening device for producing fine iron powder Technical Field The utility model relates to the technical field of crushing and screening devices for fine powder production, in particular to a crushing and screening device for iron fine powder production. Background The crushing and screening device for producing the iron fine powder is mainly used for crushing raw ores to proper granularity and separating fine powder meeting requirements, and the core equipment comprises two large modules, namely a crusher and a screening machine. The crushing link adopts a jaw crusher, a cone crusher or a twin-roll crusher, massive iron ores are crushed into coarse particles step by step in the modes of extrusion, impact and the like, and the screening link depends on a vibrating screen, a drum screen or a linear screen, and the crushed materials are subjected to particle size classification by utilizing screens with different meshes. In practical application, the traditional device often has the problems that the screen surface is piled up, the screen holes are easily blocked by critical particles, the screen mesh is replaced in a complicated way and the like due to uneven material distribution. For example, the design of a single feed inlet can easily cause materials to be accumulated in a part of a screening area in a concentrated manner, so that the effective screening area is reduced, sticky particles or moist mineral powder are easy to adhere to form clusters to block the screen holes, frequent shutdown and cleaning are needed, and the screen mesh is needed to be replaced manually or the distance between the screen plates is adjusted during multi-stage screening, so that time and labor are consumed. In order to improve practicality, part of the improved design adopts a spiral guide plate to disperse feeding materials, a mechanical self-cleaning brush is added to prevent sieve holes from being blocked, or the shutdown time is reduced through a modularized quick-release screen. In addition, sealing structure optimization (such as rubber dust cover) reducible dust excessive, intermittent type formula ration unloading mechanism then avoids disposable overload to influence screening precision. Various crushing combinations exist in the crushing field, and all the crushing combinations have unique advantages and disadvantages, and the patent document with the publication number of CN 215843405U indicates that the crushed iron fine powder does not have a collecting effect and is inconvenient to use, and the patent document sieves crushed materials through the reciprocating motion of a cylinder and the cooperation of a vibrating device, so that the crushed materials can be separated, but the device has some disadvantages, crushed stones are always at the same level, blocking is easy to cause, and the device does not have multi-stage sieving and easily causes material uniformity to be reduced.
