Grinding mills for chalk are used to pulverize chalk into fine and ultrafine powder for various applications. Grinding mills for chalk typically involve crushing and grinding processes.
What is Chalk?
Chalk is a soft, white, porous sedimentary rock primarily composed of calcium carbonate (CaCO₃) in the form of the mineral calcite.
Chalk, primarily composed of calcium carbonate, requires grinding to achieve a fine particle size suitable for use in industries like construction, art, and education.
Chalk powder has many uses:
In education, it is used for writing on blackboards.
In industry, it is used as a filler in paint, rubber, plastics and paper.
In construction, it is used to make cement and concrete.
In agriculture, it is used to adjust the pH of the soil and to supplement calcium in animal feed.
In personal care and cosmetics, it is used to make toothpaste and cosmetics.
In the art field, it is used to make materials such as pastels.
Grinding Mills For Chalk
Grinding mills are used to process chalk into fine powders of different fineness levels, depending on the intended application.
Here are some common types of SBM Ultrafine Powder Tech’s grinding mills used for chalk, along with their capabilities and the typical fineness they can achieve:
1. Raymond Mill
Raymond mill is a good choice if you want to process 80-400 mesh chalk powder.
YGM Raymond Mill is a traditional grinding mill that uses rollers and a ring to grind materials.
It is widely used in small and medium-sized stone powder grinding plants.
It is suitable for medium-fine chalk grinding in paint, rubber, and paper industries.
2. Pendulum Roller Milll
CLRM Pendulum roller mill is excellent for large-scale production and processing.
It uses large rollers to crush and grind materials against a rotating grinding table.
The fineness range is 80-600 mesh (180-25 microns).
It is suitable for producing ultrafine chalk powder for high-end applications.
3. Micro Powder Mill
HGM Micro powder mill is designed for high-performance ultrafine powder production.
The fineness range is 325-2500 mesh (45-5 microns).
It is suitable for producing superfine chalk powder for specialized uses in the paint, plastic, and rubber industries.
4. Ultrafine Grinding Mill
CLUM Ultrafine grinding mill is perfect if you need high-quality ultrafine chalk powders.
It can achieve a fineness range of 400-3000 mesh (38-5 microns).
This modern mill is ideal for producing ultrafine chalk powder used in cosmetics, pharmaceuticals, and other high-precision applications.
5. Ball Mill
Ball mill is ideal if you need to grind materials by rotating around a horizontal axis.
It is a cylindrical mill partially filled with material to be ground plus the grinding medium (usually steel balls).
The fineness range is 75-200 mesh (200-75 microns).
It is often used for coarse to medium-fine grinding of chalk in cement and construction materials.
6. Hammer Mill
Hammer mill is useful for crushing and grinding materials into fine powders.
It uses hammers and has a fineness range of 100-400 mesh (150-38 microns).
It is commonly used for medium-fine grinding of chalk for agricultural and industrial purposes.
