A 1830×7000 cement ball grinding mill is a large-sized ball mill commonly used in cement plants for grinding raw materials or clinker. Here are the key details about this equipment:
Specifications & Features:
1. Model & Dimensions:
– 1830×7000 refers to the inner diameter (1830 mm or 1.83 m) and length (7000 mm or 7 m) of the mill.
– Effective grinding length is slightly less (~6.5–6.8 m) due to liners.
2. Capacity:
– Typically processes 15–25 tons/hour (varies based on material hardness, feed size, and discharge fineness).
– Suitable for grinding cement clinker, slag, or raw materials like limestone.
3. Rotation Speed:
– Critical speed (~75% of theoretical critical speed): ~23–25 RPM (depends on design).
4. Motor Power:
– Required power: ~250–315 kW (depends on load and grinding efficiency).
5. Grinding Media (Balls):
– Ball load: ~20–30 tons (steel balls of varying sizes, e.g., 30–90 mm).
– Material: High-chrome or forged steel for durability.
6. Lining Plate:
– Wave, step, or rubber liners to protect the shell and enhance grinding efficiency.
7. Discharge Type:
– Overflow or grate discharge, depending on application.
8. Applications:
– Cement clinker grinding (finish grinding).
– Raw material preparation (limestone, clay, iron ore).
– Industrial minerals processing.
