Technical Field

[0001] The utility model relates to the technical field of lightweight concrete aggregate, in particular to a raw material screening device with a shaking structure. Background Art

[0002] Lightweight concrete aggregate is a kind of aggregate material in concrete, usually made of foamed concrete or lightweight aggregate, with low density and high thermal insulation performance. Lightweight concrete aggregate is widely used in the construction industry to reduce the weight of buildings and improve their earthquake resistance and thermal insulation performance. At the same time, lightweight concrete aggregate can also reduce the amount of concrete used and reduce the cost of buildings. It is an environmentally friendly, economical and efficient building material.

[0003] During the recycling process of concrete lightweight aggregate, it needs to be crushed and then screened so that aggregates with qualified particle sizes can be screened out and collected for subsequent processing.

The aggregate is usually concentrated in the middle of the screening plate, and the aggregate cannot be evenly laid on the surface of the screening plate. Therefore, it is very easy to get blocked during the feeding process, and the screening plate is usually in a static state, so the screening efficiency is slow. To solve this problem, we proposed a raw material screening equipment with a shaking structure. Utility Model Content
