Description

Technical Field

[0001] This utility model relates to the technical field, specifically to concrete aggregate particle size testing equipment. Background Technology

[0002] Concrete aggregate particle size testing equipment is a device specifically designed to test the particle size of aggregates in concrete. Concrete aggregate particle size testing mainly detects the particle composition of aggregates, that is, the proportional distribution of particles of different sizes in the aggregates. This test is crucial to the quality of concrete.

[0003] Existing devices use vibration to sieve out the stones and sand inside the concrete, and then weigh the stones and sand to detect particle size. However, the sieving process cannot remove fine dust from the concrete. These dust particles adhere to the surface of the stones and sand, resulting in inaccurate weighing results and ultimately inaccurate data, which has limitations.

[0004] The reason for this problem is that although most of the stones and sand can be effectively separated during the vibrating screening process, it is difficult to completely remove the fine dust particles in the concrete. These dust particles will adhere to the surface of the stones and sand or be mixed in during the screening process, resulting in inaccurate weighing results and inaccurate final data, which has limitations. In order to address the shortcomings of the existing technology, this utility model provides a concrete aggregate particle size detection device to solve the above problems. Utility Model Content
