Why is limestone so important to human development?
Despite relatively short application history is, limestone products on the market now far exceed the sum of other non-ferrous metal products.
applications of limestone
Among the ten key industries, five belongs to the field of transportation which is a crucial area for lightweight development needing a large amount of limestone. The other five are information technology, robot, power industry, agricultural machinery, and medicine, which are also the main application areas of limestone.
Besides, limestone makes our lives more convenient. From the most commonly used items, SBM Machine can see that almost all home appliances use limestone.
Uses of Limestone
- Coarser than 200 mesh:Lightweight bricks, soil conditioners, etc.
- 200 mesh-325 mesh:Desulfurization powder, cement, glass, chalk, etc.
- 400 mesh-800 mesh:Rubber, plastic, sealing materials, chemicals, toothpaste, etc.
- 1250 mesh-1500 mesh:Coatings, stationery, cables, cosmetics, medicine, etc.
- 2000 mesh-3000 mesh:High-end papermaking, high-end PVC, high-end fillers, high-end silicone glue, etc.
Tips on choosing limestone mill
The limestone mill can efficiently and quickly grind limestone into limestone powder with different particle size specifications. The following types of limestone mills are favored by limestone powder manufacturers.
Raymond mill is an earlier and commonly used milling machine. It can grind limestone with Mohs hardness ≤9.3 and humidity ＜6%.
The final calcium carbonate powder fineness of Raymond mill ranges from 80 - 325 mesh, which can meet the fineness requirements of limestone powder in most industries.
In addition, with the development of technology, the structure and function of the Raymond mill have also been improved.
The specific improvements are as follows:
Its powder separator has been changed from dragging inside the cavity to a suspended transmission outside the cavity, enhancing its stability and durability.
The grinding roller also rotates around the central axis, so the Raymond mill can work with greater grinding force and higher operating speed.
The barrel shape protects the wind box and air ducts from being blocked.
The electrical system adopts centralized control, which reduces labor costs.
