Which model of lithium ore ball mill should be selected for a capacity of 25 tons per hour?

Recommended Model: Φ2.4×7m Ball Mill

Parameters: 2.4m cylinder diameter, 7m length, 20.4 rpm rotation speed, 35 tons/hour production capacity, 280kW main motor power.

 

Suitability: Slightly higher than the 25 tons/hour requirement, allowing for capacity fluctuations. The power is moderate, suitable for medium-hardness lithium ore.

 

Alternative Model: Φ2.2×7m Ball Mill

Parameters: 2.2m cylinder diameter, 7m length, 21.6 rpm rotation speed, 22-30 tons/hour production capacity, 380kW main motor power.

 

Applicable Scenarios: If the lithium ore has high hardness or requires finer grinding (e.g., output particle size ≤0.4mm), this model has higher power and can meet the needs.

 

Key Selection Factors

Material Characteristics: For medium-hardness lithium ore, attention should be paid to the liner material (high manganese steel recommended) and the wear resistance of the steel balls.

 

Transmission method: Gear drive + center discharge is preferred to ensure stability and grinding efficiency.

 

Energy consumption and maintenance: The Φ2.4×7m model has a lighter total weight (67 tons), resulting in lower long-term operating costs.
