Silica Sand Size Chart: A Comprehensive Guide
When it comes to the world of construction and industrial applications, silica sand is a material that plays a crucial role. Its versatility and abundance make it a staple in various industries, from glass manufacturing to foundry processes. To understand the properties and uses of silica sand, it’s essential to familiarize yourself with the silica sand size chart. In this article, we will delve into the details of the silica sand size chart, exploring its dimensions, applications, and the factors that influence its grading.
Understanding the Silica Sand Size Chart
The silica sand size chart is a reference tool that categorizes silica sand based on its particle size. Particle size is a critical factor that determines the sand’s properties and its suitability for different applications. The chart typically ranges from fine, powdery sand to coarse, granular sand, with various sizes in between.
Particle sizes are usually measured in mesh numbers, which indicate the number of openings per linear inch in a standard sieve. For example, a 200-mesh sieve has 200 openings per inch. The smaller the mesh number, the finer the sand. Conversely, a higher mesh number corresponds to coarser sand.
| Mesh Number | Particle Size (mm) | Particle Size (inches) |
|---|---|---|
| 4 | 0.25 | 0.01 |
| 10 | 0.15 | 0.006 |
| 20 | 0.075 | 0.003 |
| 40 | 0.0425 | 0.0017 |
| 60 | 0.035 | 0.0014 |
| 100 | 0.025 | 0.001 |
| 200 | 0.0125 | 0.0005 |
| 325 | 0.009 | 0.00035 |
| 400 | 0.0075 | 0.0003 |
| 500 | 0.006 | 0.00025 |
| 600 | 0.005 | 0.0002 |
| 800 | 0.004 | 0.00015 |
| 1000 | 0.003 | 0.0001 |
Applications of Silica Sand Based on Size
The particle size of silica sand significantly influences its applications. Here are some common uses of different sizes of silica sand:
-
Fine sand (mesh numbers 200-400): This type of sand is often used in glass manufacturing, as it provides a smooth, clear finish. It’s also used in foundry processes for casting metal parts.
-
Medium sand (mesh numbers 40-100): Medium sand is suitable for applications that require a balance between particle size and flowability, such as in the production of concrete and asphalt.
-
Coarse sand (mesh numbers 10-40): Coarse sand is ideal for applications that require a higher level of abrasiveness, such as in sandblasting and concrete mixing.
