Ball Mill for Dolomite Powder Grinding

In the field of chemical raw materials, ball mill for dolomite powder grinding has become a key technology to unlock the value of dolomite powder. Derived from natural mineral resources, dolomite powder plays an indispensable role in modern industrial production with its versatile properties and wide applications. Let us explore the characteristics, production process, and industrial uses of this important material.

What is Dolomite Powder?

Dolomite powder is produced from natural dolomite through crushing, grinding, and classification processes. Dolomite is a carbonate mineral with the chemical formula CaMg(CO₃)₂, theoretically containing 30.4% CaO, 21.7% MgO, and 47.9% CO₂.

Properties and Characteristics

Stable Chemical Composition
Dolomite powder contains calcium carbonate and magnesium carbonate in nearly equal proportions, ensuring high stability and consistency.

Excellent Physical Properties

• High whiteness: Premium dolomite powder reaches over 90%.
• Moderate hardness: Mohs hardness of 3.5–4.0.
• Easy to grind: Can be processed into products of various fineness levels.

Good Thermal Stability
Maintains stable performance under high temperatures, making it an excellent refractory material.

Unique Chemical Nature
Serves as both a calcium source and magnesium source, offering unique advantages in many applications.

Environmentally Friendly
A natural mineral that is non-toxic and safe, fully meeting environmental protection requirements.

Wide Applications

Construction Materials

• Ceramics: Reduces sintering temperature, improves strength and thermal stability.
• Glass: Contributes MgO, enhancing chemical durability and mechanical strength.
• Artificial marble: Used as filler, lowers cost while improving performance.

Environmental Protection

• Flue Gas Desulfurization: Reacts with SO₂ to form calcium sulfate, achieving purification.
• Water Treatment: Adjusts pH and removes impurities.

Metallurgy

• Refractories: For linings of steel furnaces and rotary kilns.
• Magnesium Production: Key raw material for extracting metallic magnesium.

Dolomite Powder Preparation: Ball Mill and Classification System

In modern production, ball mill classification technology is the core for achieving high-quality and controlled particle size of dolomite powder.

• Raw Material Preparation
  Natural dolomite is crushed to a suitable size before entering the ball mill system.
• Ball Mill Grinding
  • Conducted via dry or wet methods.
  • Ensures uniform fineness of powder particles.
  • Adjustable grinding media, rotation speed, and time allow precise particle size control.
• Classification
  • Paired with high-efficiency turbine or inert gas-protected classifiers.
  • Enables precise particle size control (e.g., D97: 10 μm, 5 μm, or finer).
  • Produces products tailored for ceramics, coatings, plastics, and other industries.
• Process Advantages
  • Narrow particle size distribution, stable quality.
  • Low energy consumption, high output.
  • Avoids over-grinding, improves powder performance.
