After the stone machine-made sand equipment is crushed and processed, the particle size of the finished machine-made sand will be not uniform, the gradation is not ideal, and it contains more stone powder and mud powder, which seriously affects the overall appearance and quality of use. So how to further improve the quality of the finished machine-made sand? The following are two solutions for you.

1. Adjust and add a vibrating screen

The gradation of the machine-made sand is poor and the fineness modulus is large, mainly because the cumulative screening rate of 2.36mm and the pass rate of 0.075mm are large. By replacing the vibrating screen to complete the adjustment of the vibrating screen hole size, the gradation and fineness modulus of the machine-made sand can be effectively controlled. Practice has proved that when the vibrating screen hole size is 3.5mm, the fineness modulus of the machine-made sand produced is generally within 3.4, and the gradation meets the standard requirements. After the sand making machine-made sand is made, adding a screening procedure for detailed screening and grading can make the gradation of the finished product more reasonable, and in the screening process, it can also remove some of the stone powder and soil mixed in it to improve the overall quality.

2. Configure a bucket sand washer

The surface of the finished machine-made sand is usually inevitably attached with a small amount of stone powder with particles less than 0.075mm, and is also mixed with fine sand and mud powder, which not only affects the overall grading, but also reduces the quality of the finished sand. When the stone powder content is high, it is not conducive to the preparation of high-strength concrete. Usually, most sand-using industries require that the powder content of the finished machine-made sand should not exceed 3%. The bucket sand washer can effectively wash, grade and dehydrate the finished machine-made sand, improve the cleanliness, and make its powder and mud content meet the sand standards.
