Description

Technical Field

[0001] This utility model relates to the field of sand making technology, and more specifically, to a powder lifting machine for a sand making machine. Background Technology

[0002] Sand making refers to the process of processing rocks, ores, or other solid materials into sand and gravel materials suitable for use in construction, roads, bridges, and other engineering projects. This process typically involves multiple steps aimed at producing artificial sand that meets specific requirements for particle size distribution, shape, and purity. During the sand making process, the sand particles are separated by a sand and powder separator, and the separated powder needs to be transported to a dust removal device using a powder elevator for dust collection.

[0003] Based on the above, the inventors have discovered the following problems: In current sand making processes, screw conveyors are typically used to feed powder. However, the powder produced in sand making processes has high hardness, and the powder lifting process can easily cause severe wear on the edge of the screw blades and the inner wall of the conveying pipe, making it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a powder lifting machine for sand making machine in order to achieve a more practical value. Utility Model Content
