Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of raw material screening devices, specifically to a screening device for preparing magnesium aluminum spinel bricks. Background Technology
[0002] Magnesium-aluminate spinel bricks are widely used in high-temperature industries such as steel, cement, and glass due to their excellent high-temperature performance, erosion resistance, and thermal shock stability. During their preparation, the particle size uniformity of the raw materials plays a decisive role in the performance of the bricks.
[0003] With the continuous advancement of technology, vibrating screening equipment has been introduced into the field of magnesium aluminate spinel brick preparation. Although vibrating screening improves screening efficiency to some extent, the high hardness of magnesium aluminate spinel raw materials causes severe wear on the screen mesh during vibration, resulting in a short screen lifespan and frequent screen replacements. This not only affects the continuity of production but also further increases production costs. Existing screening devices still have shortcomings in accurately classifying magnesium aluminate spinel raw materials of different particle sizes, making it difficult to meet the strict particle size classification requirements for preparing high-quality magnesium aluminate spinel bricks. Therefore, developing a high-efficiency, durable, and accurately classifying screening device for magnesium aluminate spinel brick preparation is of significant practical importance.

[0014] Beneficial effects
[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:
[0016] This invention utilizes a vibrating device structure. Users can connect one side of each screen plate to a vertical plate on the vibrating motor side via a connecting plate.
