Drum-type sandstone aggregate drying and particle screening system

Abstract

The invention relates to the technical field of engineering materials, in particular to a drum-type sandstone aggregate drying and particle screening system. The drum-type sandstone aggregate drying and particle screening system comprises a drying unit, a screening unit and a mass acquisition unit; the drying unit comprises a horizontally arranged drum, a heating housing arranged on the drum surface of the drum and a high-strength hot-air fan arranged on one side of the drum; the drum is driven to rotate by external force; the screening unit comprises screen meshes arranged below one side of the drum, and a vibration device arranged at the bottom of the screen mesh; discharge ports are formed in one sides of the screen meshes; and a mass acquisition system is arranged below the discharge ports of the screen meshes. Sandstone sampling and gradation measurement work can be completed on a construction site, the processes of sample transportation and the like are reduced, and the water ratio and the gradation resultant errors are reduced.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a drum-type sand and gravel drying particle system. Background technique [0002] Particle gradation is an important indicator of granular materials such as sand and gravel materials, sandy soil materials, etc. It reflects the relative content of each particle group in the granular material, and can be used to judge whether the uniformity of the granular material or whether the gradation is good and whether it can meet the requirements. actual engineering needs. During the construction of geotechnical engineering, there are strict requirements on the particle gradation of sand and gravel materials. If there is a deviation in the gradation, it will have a great impact on the quality of the project, and even affect the safety of the project. Grain grading is generally obtained through particle sieving, which is represented by the sieve residue of a set of sieves with...

AI Technical Summary

Problems solved by technology

At the same time, the sand and gravel samples need to be dried before sieving, and the construction period cost and labor cost are relatively large

Especially on the engineering site, there is no ability to quickly dry on site, and samples must be taken indoors for drying, which further increases the cost of sampling and transportation
