Technical Field
[0001] This utility model relates to the field of sand making technology, and more specifically, to a sand particle powder separator for use in sand making machines. 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. A sand and gravel separator is a specialized piece of equipment used to separate sand particles from fine powders (such as stone powder) in sand and gravel mixtures, ensuring the quality of sand and gravel products, reducing waste, and meeting the particle size and purity requirements of different industries.
[0003] Based on the above, the inventors have discovered the following problems: In the current sand and powder separator, fine sand particles easily clog the screen during use, resulting in a decrease in separation efficiency and 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 sand and powder separator for sand making machines, in order to achieve a more practical value. Utility Model Content
