Characteristics of Limestone Powder:
The limestone is a common nonmetal mineral, its main component is calcium carbonate, and limestone is the main raw material of natural calcium carbonate for glass production, lime and limestone are largely used as building materials, are important raw materials of many industries, calcium carbonate can be directly processed into stone and fire into lime.
Use of Product:
1. Foundry sand for machinery manufacturing
The limestone produces casting sand degree is 28 ~ 75 meshes, this kind of sand has better performance than quartz sand, good collapsibility, easy to clean fall sand, improve the surface quality of the casting, increase the casting surface finish, currently casting sand is in short supply.
2. Used for Industrial building materials coating industry
Lime stone milled to 100-200 meshes, is the main raw material in mixing plant, express way construction. Limestone mill coating greatly improves the system’s thixotropy, can significantly increase the coating adhesion, wash resistance, stain resistance, increase the strength and surface finish, can be instead of titanium dioxide, has good effect for settlement, and reduces the cost.
3. For desulfurization sorbent production
Limestone milled to 200-325 meshes can replace the original lime or hydrated lime, mixed with water and stir to a slurry in absorption tower, absorb slurry, contact and maxed with smoke, sulfur dioxide of smoke will be removed after the chemical reaction with calcium carbonate in the slurry and the air, the eventually reaction product is plaster, the flue gas after desulfurization charges into the chimney by heating up. This process equipment is mature, has high desulfurization efficiency, can be widely applied..
4. Used as filler for plastic, coating and other process
For this kind of products are the raw material of natural calcium carbonate mineral, generally. average particle size 400-800 meshes mineral powder can be used as coating stuffing, 800-1250 meshes can be used for plastic, rubber, paper packing, 2500 meshes can be used as ink filter after the activation treatment.
Prospect of Development:
Limestone mineral resources are rich in China, accounting for more than 64% of the world's reserves, is one kind has advantage of natural resources. At present abroad developed countries such as Japan and the United States, have good results
It enters into the Chinese market as the foreign high-grade calcium carbonate materials and pickings, which promotes the domestic technical progress, speeds up the rapid growth of our calcium carbonate deep processing, and develops fast toward the direction of pluralism, specialization, and refine, and expands more applications, its prospect is very optimistic!
Configuration Program:
Limestone powder works relatively maturely and steadily. Conventionally take fine degrees from 30 meshes to 400 meshes Raymond milling machine, 200-2500 meshes fine grinding mill. Kefid has researched grinding technology for a long-term, and connects with the foreign advanced technology standards; the super fine powder machine can reach 3000 meshes. Raymond milling machine equipment with high efficiency, less maintenance, low energy consumption, high production, deeply received by customers at home and abroad.
Specific process configuration should be based on the specific analysis of the actual situation of the customer site, welcome to visit and experience Kefid’s star service!
