Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of crushing and sorting, in particular to a crushing and sorting device for steelmaking tailings. BACKGROUND

[0002] Steel slag tailings are a kind of waste produced in the process of steel production, which is composed of slag, sintered ore, coke ash and other substances. Due to the rich calcium oxide and silicon oxide, a small part of the tailings is used to make or serve as building materials, such as participating in the production of cement clinker, serving as aggregate in concrete mixture or admixture. Before the tailings are used to make or serve as building materials, they need to be crushed. In the existing technology, there is no crusher specially developed for tailings. Most enterprises use jaw crushers for crushing ore during crushing. Due to the difference in composition and hardness between ore and tailings, only the moving jaw plate and fixed jaw plate are used to crush the tailings by extrusion, which has poor crushing effect and uneven particle size after crushing. Moreover, the moving jaw plate and fixed jaw plate are easily jammed during crushing, which seriously affects the crushing efficiency.

[0003] In related technology, reference can be made to Chinese patent with publication number CN219943158U, which specifically discloses a crushing and sorting device for steelmaking tailings. When the crushing and sorting device for steelmaking tailings is used, a slidable plug plate is arranged in the collection box, and two guide plates are arranged inside the collection box. The guide plates arranged in inverted V shape can well distribute the steel slag particles, avoiding the accumulation of steel slag on one side. When the steel slag needs to be taken out, the plug plate can be slid out of the collection box. The steel slag particles originally located on the top of the plug plate will fall into the collection box after losing the plug plate, which can loosen the steel slag and make the steel slag accumulated in the collection box into a hill shape, facilitating the removal of the steel slag and improving the overall practicability. The structure is simple, convenient to operate and has strong practicability.

[0004] The applicant found that the above-mentioned crushing and sorting device for steelmaking tailings has the following disadvantages: although it can prevent the accumulation of steel slag, the steel slag needs to be manually removed when it is taken out, which cannot be continuously collected at the same time, reducing the work efficiency.

[0005] Therefore, the present technical solution proposes a crushing and sorting device for steelmaking tailings to better solve the above-mentioned problems. UTILITY MODEL CONTENTS
