Description

Technical Field

[0001] The utility model relates to the field of recycled aggregates, in particular to a recycled aggregate screening device. Background Art

[0002] The recycled aggregate screening device is one of the key equipment in the process of resource utilization of construction waste. Its main function is to screen the aggregate in the construction waste, remove impurities and particles that do not meet the requirements, and obtain high-quality recycled aggregate. These recycled aggregates can be reused in the production of building materials, such as concrete, bricks, etc., to achieve the recycling of resources.

[0003] However, general screening devices screen aggregates on the screen by means of vibration or rotation, which makes the holes of the screen easily blocked when screening the aggregates. It is too troublesome for workers to clean them. In addition, a large amount of dust is generated when screening the aggregates, which can easily cause breathing difficulties for the workers and make the screening efficiency of the aggregates low. For this reason, we proposed a recycled aggregate screening device. Utility Model Content
