Roller type screening crusher and design method thereof

Abstract

The invention discloses a roller type screening crusher and a design method thereof. The crusher elevates crushed materials to a certain height, and crushing is achieved through mutual impacting and grinding actions of material falling; and after crushing, the materials smaller than screen plate holes fall into a material collecting hopper at the lower portion of the roller type screening crusher through the screen plate holes and are continuously discharged through a conveying device, and therefore the functions of synchronous crushing and screening of the crushed material are achieved. The roller type screening crusher is large in crushing ratio, high in productivity, low in energy consumption and simple in structure, and the product granularity guaranteeing degree is high. The riding wheel supporting design is adopted and is high in environment adaptability, capable of saving investment and low in maintaining difficulty in comparison with a hybrid bearing supporting manner. A chain drive manner is adopted in a roller body and similarly has the beneficial effects of being high in environment adaptability, capable of saving investment and low in maintaining difficulty in comparison with a gear engagement transmission manner. Metal and sundries contained in the materials can be discharged from the tail end of the crusher in a regular material emptying manner, and downstream production and equipment cannot be influenced, wherein the sundries are not prone to breakage.

Description

technical field [0001] The invention relates to a drum type screening crusher and a design method thereof, and belongs to the technical field of supervisory machinery equipment. Background technique [0002] During the electrolytic aluminum production process, the electrolyte blocks cleaned from the anode residues returned from the electrolysis plant and the electrolyte blocks on the pallets dumped from the loading and unloading station need to be crushed to a certain size and then returned to the electrolytic cell for continued use. [0003] For a long time, electrolyte crushing mainly adopts jaw crusher plus impact crusher or roller crusher for secondary crushing. The electrolyte crushing system has problems of low crushing efficiency, high equipment failure rate, heavy equipment maintenance and repair workload, and high labor intensity. The problem has not been solved well. At present, some manufacturers try to replace the impact crusher with the self-grinding machine for...

Problems solved by technology

[0003] For a long time, electrolyte crushing mainly adopts jaw crusher plus impact crusher or roller crusher for secondary crushing. The electrolyte crushing system has problems of low crushing efficiency, high equipment failure rate, heavy equipment maintenance and repair workload, and high labor intensity. The problem has not been solved well. At present, some manufacturers try to replace the impact crusher with the self-grinding machine for secondary crushing, and the output has been greatly increased. However, the material discharged from the self-grinding machine is too fine, almost all of which are powder materials. Conducive to electrolytic production needs
