At Shikhar Microns, we've perfected the dolomite powder manufacturing process using advanced ball mill and raymond machine technology. Our 27+ years of experience in Rajasthan, India has enabled us to develop efficient processes that deliver high-quality dolomite powder for various industrial applications.
Understanding Dolomite Powder
Dolomite powder is a sedimentary carbonate rock composed primarily of calcium magnesium carbonate (CaMg(CO₃)₂). It's widely used in construction, glass manufacturing, agriculture, and various industrial applications due to its unique properties and cost-effectiveness.
Key Properties of Dolomite
- Chemical Formula: CaMg(CO₃)₂
- Hardness: 3.5-4 on Mohs scale
- Specific Gravity: 2.8-2.9
- Color: White, gray, pink, or brown
- Applications: Construction, glass, agriculture, steel industry
Our Manufacturing Process Overview
Our dolomite powder manufacturing process involves several critical stages, each designed to ensure optimal quality and consistency. We use state-of-the-art ball mill and raymond machine technology to achieve the desired particle size distribution and quality standards.
Stage 1: Raw Material Selection and Preparation
The process begins with careful selection of high-quality dolomite deposits from our Rajasthan mines:
- Quality Assessment: Testing raw materials for chemical composition and physical properties
- Grade Selection: Choosing deposits with optimal CaMg(CO₃)₂ content (typically 90%+)
- Size Preparation: Initial crushing to prepare materials for grinding
- Moisture Control: Ensuring optimal moisture content for processing
Stage 2: Primary Crushing and Size Reduction
Raw dolomite rocks undergo primary crushing to reduce size and prepare for grinding:
- Jaw Crushers: Initial size reduction to 6-8 inches
- Cone Crushers: Secondary crushing to 1-2 inches
- Impact Crushers: Fine crushing for specific applications
- Size Classification: Screening to separate different particle sizes
