In quarrying and construction, wasted material means wasted profit. Crusher dust is a completely natural byproduct of various mining operations that helps manufacturers increase profits. Some companies spend more time refining their crusher dust than others, and the rougher versions of the dust are sometimes known as manufactured sand.
Crusher Dust Definition
When furnaces and quarrying procedures produce slag from treating different types of stone, manufacturers gather this slag together and grind it down into crusher dust. This dust is made of a variety of materials, but often contains a large amount of silicates and aluminosilicates. This crusher dust is then shipped to different companies to be used in construction mixtures.
Crusher Dust Description
In appearance, crusher dust has a grayish or brownish tone with very fine aggregate particles, like a soft sand. These particles, when looked at under a microscope, are rough cubes and individually have a rough surface texture.
Crusher Dust Uses
Crusher dust is used primarily as filler and cement aggregate. Construction contracts use the sand to weigh down objects or fill in cracks in patios or other stone creations. When used in concrete, the crusher dust mixes in with larger aggregate to help form a specific texture. The dust is also used to make mortar and other similar materials.
Crusher Dust Benefits
Crusher dust has many of the useful properties of the stone that it comes from. It is very heat resistant and contains no plastic chemicals that may be toxic to the surrounding environment over time. The chemical nature of crusher dust is very dependable and largely alkaline which helps manufacturers use it confidently in a variety of materials. It is also durable, strong, and can be easily compressed into tight spaces.
There are different grades of crusher dust. Usually aggregates larger than 5mm in diameter are considered a larger class of sand, while aggregates smaller than 5mm are grouped together and considered, collectively, crusher dust. The most sophisticated plants measure the dust out even further and add in stabilizing or precoating agents before the dust is packaged and sold.
