Seashore quartz sand gravity separation test

Beach quartz sand is a common building material widely used in fields such as architecture, roads, and bridges. However, due to different factors in the mining and processing processes, the quality of Haibin quartz sand may vary. In order to improve the quality of beach quartz sand, we conducted a re selection experiment.

test method

Firstly, we collected samples of beach quartz sand from different sources and conducted preliminary screening and washing treatment on them. Then, we divided the samples into different groups and conducted reselection experiments separately.

The specific steps for the re selection test are as follows:

1. Screening: Place the sample into a sieve and separate quartz sand of different particle sizes through a vibrating sieve.

2. Washing: Put the separated quartz sand into water, stir and wash to remove impurities and sediment.

3. Re-selection: Place the cleaned quartz sand into a gravity separator and separate the heavy and light minerals through gravity separation.

4. Magnetic separation: Place the reconcentrated quartz sand into a magnetic separator and separate the magnetic and non magnetic minerals through magnetic separation.

5. Post selection treatment: Dry and package the separated quartz sand for future use.

test result

After re selection experiments, we obtained a batch of high-quality seaside quartz sand, with the main characteristics as follows:

1. Uniform particle size distribution: After screening and washing treatment, the particle size distribution of quartz sand is more uniform, which can meet the needs of different building materials.

2. Low impurity content: After gravity and magnetic separation treatment, the impurity content in quartz sand is greatly reduced, which can improve its service life and strength.

3. Low magnetic mineral content: After magnetic separation treatment, the magnetic mineral content in quartz sand is greatly reduced, which can avoid the impact on building materials.

conclusion

Through the seaside quartz sand gravity selection experiment, we have obtained a batch of high-quality quartz sand that can meet the needs of construction, roads, bridges and other fields. At the same time, we also found that the re selection test can effectively improve the quality of seaside quartz sand and promote the development of the construction material industry.
