The Grain Shape Of Machine Made Sand Can Be Improved By Qualitative Change

Last Update:2020-05-10 13:07:18

As we know, fine aggregate is one of the important components of concrete. The grain type and grading characteristics of sand affect the quality of concrete. The angularity of sand aggregate from strong to weak is granite machine-made sand, limestone sand and river sand. The experimental results show that under the same mix ratio, the mortar prepared by limestone machine-made sand with high comprehensive index of particle size has better working performance and mechanical performance, and the concrete made of it has better mechanical performance and chloride ion permeability resistance. Of course, the source of these good finished materials - complete set of building aggregate preparation work is indispensable.

The complete equipment for building aggregate preparation benefits from the original dry sand preparation system. It is comprehensively updated and upgraded on this basis. The tower structure is adopted, and the equipment for feeding, sand preparation, screening, sand particle optimization, humidification, mixing and dust removal are integrated. The preparation process and complete equipment for dry sand preparation are developed. There is no sewage and dust discharge in the sand preparation process, making the performance of machine-made sand comparable Natural sand can significantly improve the quality of concrete.
