What are the different fineness limestone application fields and usage?

Limestone is a non-metallic mineral, It is the main raw material for the production of cement, lime and other products. It is also an important raw material for the production of industrial materials such as calcium oxide and calcium carbonate. It is at the forefront of the industrial chain.

In terms of technological process and physical characteristics, raw limestone ore undergoes a series of processes such as beneficiation, crushing and classification, is processed different finenesses according to customer needs. Under normal circumstances, the company refers to limestone products with a fineness between 0-3mm as lime powder, and products with a fineness greater than 3mm are called limestone.

Different Fineness

Limestone can be divided into four different specifications according to the different grinding fineness: 200 mesh 95%, 325 mesh 99%, 325 mesh 99.9%, 400 mesh 99.95%, used in different industrial.

Limestone Application Field And Usage

Metallurgical Industry: As a carrier of calcium oxide in iron and steel, it becomes fusible slag.

Chemical Industry: Filler for rubber industry; extender for paper and paint; raw material for calcium carbide; also widely used in the manufacture of bleaching agent, alkali production, seawater extraction of magnesia, nitrogen fertilizer, plastics, organic chemicals, calcium carbide.

Construction Industry: Production of lime slurry for construction, various types of lime, gravel, asphalt ingredients for road construction, etc.

Agriculture: Calcined lime is used to neutralize acid soil and as feed.

Building Materials Industry: Cement, glass, ceramics, refractories.
