Fly ash is not easy to grind when entering the mill, because it is already ash, it will fly with the wind when it enters the mill and will not form a material layer at the bottom of the vertical mill. Other mixtures need to be added for grinding. After ash is processed, it is more common to be used as cement admixture, so the type of choice is usually LM series cement raw material vertical mill.

What Is The Fineness Standard Of Secondary Fly Ash? 

The secondary fly ash fineness (325 mesh) requires a 45μm square hole sieve residue not more than 30%. Secondary fly ash is widely used in reservoirs, dams, high-rise buildings, railways, highways, bridges, culverts, highways, chemicals, oil fields, etc. As a concrete additive, it can replace part of cement and reduce project cost.

What's Vertical Mills Output Fineness Are Used For Secondary Fly Ash? 

If the cement manufacturer produces cement admixtures of about 325 mesh and within 325 mesh, the cement raw material vertical mill is usually used for grinding, and other heavier materials such as limestone, clay and slag are added for mixing and grinding.

LM series cement raw material vertical mill focuses on the fields of coal, cement, slag, and non-metallic ore powder. The particle size of the finished product is 22-180μm, and the production capacity is 5-700t/h.

LM series cement raw material vertical mill is a high-efficiency and energy-saving advanced grinding equipment that integrates drying, grinding, grading, and conveying, which is developed by SBM through learning and introducing foreign advanced technology, after more than 20 years of painstaking research and development.

SBM LM series cement raw material vertical mill has high grinding efficiency, low power consumption, large feed size, easy adjustment of product fineness, simple equipment process flow, small floor space, low noise, low dust, easy use and maintenance, and operation Advantages of low cost and low consumption of wear-resistant materials. It can be widely used in electric power, metallurgy, cement, chemical, non-metallic mining and other industries, mainly used for cement raw meal, clinker, lime powder for power plant desulfurization, slag powder, manganese ore, gypsum, coal, barite, calcite, etc. The materials are processed by grinding.
