First, the sand dust test box uses blowing sand composed of quartz crystals with a sub-angular shape. The average roundness factor is 0.2, and the Mohs hardness is 7. The sand must contain at least 95% silica by mass. Its particle size distribution is as follows:
1. 0.5% to 1.5% passes through an 850µm sieve.
2. 1.2% to 2.2% passes through a 600µm sieve.
3. 13.8% to 15.8% passes through a 425µm sieve.
4. 36% to 38% passes through a 300µm sieve.
5. 27.6% to 29.6% passes through a 212µm sieve.
6. 11.7% to 13.7% passes through a 150µm sieve.
7. 4.2% to 6.2% remains on a 150µm sieve.
In addition, the dust used in the sand dust test box consists of angular silica powder, with a mass content of 97% to 99% silica. Its particle size distribution is as follows:
1. 100% passes through a 150µm sieve.
2. 96% to 100% passes through a 106µm sieve.
3. 88% to 92% passes through a 75µm sieve.
4. 73% to 77% passes through a 45µm sieve.
These specifications ensure that the test conditions closely simulate real-world environments where fine dust and sand particles are present, providing accurate and reliable results for testing equipment durability and performance under harsh conditions. The composition and grading of the materials are carefully controlled to meet industry standards and ensure consistency across different tests.
