Fly ash European version mill MTW
Fly ash is a byproduct of burning coal in power plants, and it’s one of the most abundant industrial wastes generated globally. While it may seem like just another waste product, fly ash has proved to be an exceptional resource that can be utilized in construction and various other industries. In this blog post, we’ll explore everything you need to know about fly ash grinding process, its types of grinders, pros and cons, benefits, how to grind with MTW mill, alternatives available and more. So buckle up as we dive into the world of fly ash!

What is Fly ash?
Fly ash is a byproduct of burning coal in thermal power plants, and it’s composed of small, spherical particles that are carried away from the combustion chamber with the flue gases. Fly ash can be broadly classified into two types: class F fly ash and class C fly ash.
Class F fly ash has a higher concentration of calcium oxide (CaO) and is obtained from burning anthracite or bituminous coal. It’s usually used as a cement replacement material in construction projects due to its pozzolanic properties, which means it reacts chemically with water to form compounds that strengthen concrete.
On the other hand, Class C fly ash contains less CaO but more silica (SiO2), aluminum oxide (Al2O3), iron oxide (Fe2O3), magnesium oxide (MgO) and sulfur trioxide (SO3). This type of fly ash is generated using sub-bituminous coals or lignite. It can be used for soil stabilization, landfill cover material, and as an embankment fill material.
Fly Ash has proven to be an excellent resource that can provide substantial benefits when utilized properly.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
