Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete preparation, and in particular relates to a concrete aggregate screening device. Background Art
[0002] Aggregate is a granular loose material that acts as a skeleton or filler in concrete. Aggregate, as the main raw material in concrete, plays a skeleton and supporting role in buildings. There are two commonly used aggregates: crushed stone and pebbles. Crushed stone is natural rock or rock made by mechanical crushing and screening. The use of recycled aggregate from construction waste to partially or completely replace natural aggregate in the preparation of concrete and mortar has been successfully applied in many projects. Some commercial concrete mixing stations have set up special storage warehouses to use recycled aggregate from construction waste as a raw material. The aggregate used to prepare concrete needs to be screened multiple times before batching.
[0003] Existing screening equipment generally directly screens the crushed concrete. Since the crushed concrete particles are of different sizes, it is easy for the concrete to block the screening frame during the screening process, affecting the production efficiency of the concrete. At the same time, it is not convenient to classify and recycle concrete of various different particle sizes. Utility Model Content
