Silica dust particles from .01 to 100 μm in diameter and 10 microns or less in length are a significant health concern. To put this particle size into perspective, a human hair is about 100 μm in diameter. These small particles can remain suspended in the air for long periods of time, and they cannot be seen with the naked eye in most cases.

Particulate matter of ≤10µm (PM10) is the approximate size threshold for particles to be able to penetrate the body's natural defenses (mucus membranes, cilia, etc.) and reach deep into the lungs, potentially causing serious health issues. Silica dust ranges in size and is characterized by its jagged crystalline form.

Silica What is Silica and Silicosis? Silica, or silicon dioxide (SiO2), is a mineral that occurs naturally in crystalline or non-crystalline form. The most abundant crystalline form is α-quartz, which is the most common silicate mineral in the earth's crust. It is found in sand, sandstone, shale and granite.
Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
