[0002] Aggregate screening result verification devices are often used in the building materials industry, especially in road construction and concrete preparation, to ensure that the particle size distribution of aggregates meets specific project requirements.
[0003] At present, when verifying the aggregate screening results, it is generally necessary to first dry the cleaned samples, then place the samples on a series of standard sieves and separate them through mechanical vibration. The vibration time is recorded, and the samples are weighed after the screening is completed. Finally, the percentage of the passing amount of each sieve hole is calculated, and the grading curve is drawn. Through statistical analysis, the statistical indicators and evaluation of the aggregate quality, such as the average particle size, standard deviation, etc., are obtained.
[0004] However, there is no device for performing rapid drying and screening experiments on aggregates in the prior art to assist in verifying the aggregate screening results, resulting in that each time the verification operation is performed, not only the operation is cumbersome, but also the verification efficiency is low.
[0005] Therefore, the present application provides an aggregate screening result verification device to solve the above technical problems. Utility Model Content
