An ore dryer is a type of industrial drying equipment used to remove moisture from ores after mining and before further processing, such as smelting or refining. It plays a crucial role in mineral processing by reducing water content, improving handling, and optimizing downstream operations.

Key Features of Ore Dryers:
1. Types of Dryers:
- Rotary Dryers: Most common for bulk ores; a rotating drum heats and tumbles the material.
- Fluidized Bed Dryers: Use hot air to suspend and dry fine particles.
- Belt Dryers: For ores requiring gentle drying at lower temperatures.
- Flash Dryers: Rapid drying for finely crushed ores using high-velocity hot air.

2. Heat Sources:
- Natural gas, нүүрсний, цахилгаан, or waste heat from other processes.

3. Хэрэгжүүлэх:
- Төмрийн хүдэр, зэсийн хүдэр, Бокус, nickel ore, gold ore concentrates, гэх мэт.
- Prevents issues like freezing during transport or inefficiencies in smelting.

4. Benefits:
- Reduces weight for cheaper transportation.
- Improves crushing/grinding efficiency.
- Lowers energy consumption in subsequent processing.

Хурдхан:
- High energy costs (thermal drying is energy-intensive).
- Dust control (may require scrubbers or bag filters).
- Over-drying can lead to material degradation.

Alternatives:
For moisture-sensitive ores, mechanical dewatering (жишээ нь e., filters or centrifuges) may be used before thermal drying to save energy.
