Calcite grinding and sand production require specialized equipment to achieve high-quality aggregates for construction, ceramics, and industrial applications. A well-designed production line ensures efficiency, low energy consumption, and minimal environmental impact.
1. Jaw Crusher: Primary crushing of raw calcite (Feed size: ≤1200mm, Output: 10-350t/h).
2. Impact Crusher: Secondary crushing for finer particles (Output size: ≤40mm).
3. Ball Mill/Raymond Mill: Fine grinding (Fineness: 80-400 mesh).
4. Sand Maker: Produces uniform sand particles (Capacity: 30-500t/h).
5. Vibrating Screen: Classifies materials (Layers: 1-4, Mesh size: 3-100mm).
– Stage 1: Raw calcite is crushed by a jaw crusher.
– Stage 2: Secondary crushing via impact crusher or cone crusher.
– Stage 3: Grinding with a ball mill for ultra-fine powder.
– Stage 4: Sand making and screening for graded aggregates.
