Description

A multi-stage screening tower for real stone paint aggregate

Technical Field

The utility model relates to an aggregate screening device, in particular to a real stone paint aggregate multi-stage screening tower, belonging to the technical field of aggregate screening.

Background Art

Aggregate, also known as "aggregate", is a granular material that plays a role in the skeleton and filling of concrete and mortar. There are two types of aggregate: fine aggregate and coarse aggregate. In the process of making real stone paint, the aggregate needs to be screened, and the screening requires the use of an aggregate screening device.

Chinese patent CN220231383U discloses an aggregate screening detection device, in which the inertia generated when the screening detection box of the aggregate screening detection device moves upward causes the aggregate particles to move out of the holes, greatly reducing the aggregate particles embedded in the filter holes and improving the filtering efficiency of the aggregate.

Although the solution of the above patent can reduce the aggregate particles embedded in the filter holes, the crushing wheel of the aggregate screening device in the above patent is fixed in use position. Since the sizes of aggregates in different batches are different, large aggregates are not easy to enter the crushing wheel, which is not convenient for crushing large aggregates. Moreover, when the aggregates enter the top of the filter plate, since the filter plate is designed in a horizontal direction, the raw materials stay on the top of the filter plate for too long, thereby causing the filter plate to be blocked and affecting the operation effect of the screening device. For this reason, a multi-stage screening tower for real stone paint aggregates is provided to solve the above problems.
