Limestone Powder Making Machines: Types and Applications
Limestone powder is widely used in industries such as construction, agriculture, chemicals, and environmental protection. To produce high-quality limestone powder, specialized grinding machines are essential. Below are the most common types of limestone powder making machines and their applications.
1. Raymond Mill (Roller Mill)
– Working Principle: Uses grinding rollers to crush limestone into fine powder under centrifugal force.
– Fineness: 80–325 mesh (adjustable).
– Advantages: Stable operation, low energy consumption, suitable for medium-fine grinding.
– Applications: Used in cement additives, desulfurization agents, and soil conditioners.
2. Ball Mill
– Working Principle: Rotating cylinder with steel balls grinds limestone through impact and friction.
– Fineness: 200–400 mesh (can reach finer sizes with classifiers).
– Advantages: High production capacity, uniform particle size distribution.
– Applications: Ideal for large-scale production in cement manufacturing and mineral processing.
3. Vertical Roller Mill (VRM)
– Working Principle: Uses hydraulic pressure to grind limestone between rollers and a rotating table.
– Fineness: Up to 400 mesh or finer with dynamic classifiers.
– Advantages: Energy-efficient (~30% less power than ball mills), compact design, low noise.
– Applications: Preferred for large-scale industrial grinding in cement plants and power plants (e.g., flue gas desulfurization).
4. Ultrafine Grinding Mill
– Working Principle: Combines mechanical grinding with airflow classification for ultra-fine powder production.
– Fineness: 325–2500 mesh (D97 ≤ 5 μm).
– Advantages: Produces ultrafine powder with high purity; ideal for high-value applications.
– Applications: Used in plastics, coatings, pharmaceuticals, and advanced ceramics industries.
5.Hammer Mill
– Working Principle: Crushes limestone via high-speed rotating hammers impacting the material against liners or screens.
– Fineness: Coarse to medium (20–80 mesh). Suitable for preliminary crushing before fine grinding mills like Raymond or ball mills.
