Lithium Ore Crushing Solutions

Lithium ore is one of the main lithium-bearing minerals, mainly produced in lithium-rich granite pegmatite, coeval minerals are quartz, sodium ore, microplagioclase ore, etc., hardness of 6.5-7, hard quality, generally need to choose 2-3 sections of crushing production line.

Lithium ore crushing plant programme

Lithium ore crushing usually adopts 2-3 sections crushing process, the specific configuration according to the hardness of the ore, processing capacity and finished product size demand adjustment. The following is a typical programme:

Rough crushing stage

After mining down the raw lithium pyroxene, the size is relatively large, need to go through the jaw crusher for coarse crushing, can be a one-time crushing of large ores to medium size, jaw crusher discharging size is usually in the range of 10-30cm.

Jaw Crusher

Equipment: Jaw Crusher

Function: Crushing large raw ore (≤1200mm) to medium size (10-30cm). Technical Advantage: Deep cavity design increases capacity by 30%, overload protection mechanism enhances durability.

Medium crushing stage

The lithium pyroxene from the jaw crusher is sent to the coarse crushing cone crusher to continue crushing.

Impact Crusher

Equipment: Impact Crusher

Function: Further crushing to ≤50mm, optimising the particle size distribution.

Advantage: It is suitable for fine crushing operation, with uniform granularity of finished products, suitable for the requirement of 10-30mm finished products.

Fine crushing stage

High pressure roller mill

Equipment: High pressure roller mill

Function: Produce 0-15mm fine material to meet the needs of grinding or flotation.

Technical advantage: High-pressure roller mill achieves selective dissociation through laminar crushing, and the closed-circuit system can throw off 35% of the waste material, reducing the subsequent processing cost.

Core equipment:

Jaw Breaker + Impact Crusher + High Pressure Roller Mill

Highlights: IoT monitoring system reduces failure rate by 75%, PM2.5 emission ≤ 10μg/m³.

Auxiliary Equipment and Key Technologies

Screening Equipment

Vibrating screen: classify coarse/medium crushed products to ensure the qualified rate of particle size.
Spiral classifier: cooperate with the grinding process to improve the efficiency of fine powder separation.

Environmental Protection and Intelligent

Intelligent dust removal system: integrated cyclone dust removal + bag filtration, dust emission reaches EU standard.
Hydraulic adjustment device: real-time adjustment of crushing chamber gap, adapt to the change of ore hardness.

Selection considerations

Ore Characteristics: Select the anti-wear material according to the hardness of lithium pyroxene, lithium mica and other minerals (6.5-7 Mohs).
Energy consumption control: give priority to hydraulic drive equipment, the comprehensive energy consumption can be reduced to 4.2kWh/t.
Expandability: reserved interface is compatible with flotation, magnetic separation and other subsequent process equipment.
