The lithium ore crusher (also known as a double-roll crusher) is fully capable of serving as crushing equipment for lithium ore, particularly excelling in the medium and fine crushing stages where stringent requirements exist for product purity and particle size control.

1. Working Principle

The working principle of the double-roll crusher is highly intuitive: two parallel rolls rotate toward each other driven by an electric motor. Material enters the crushing chamber formed between the rolls through the top feed opening, where it undergoes continuous compression and shearing forces to achieve fragmentation. The discharge particle size is precisely controlled by adjusting the gap between the rolls via simple mechanical or hydraulic mechanisms. Additionally, the equipment incorporates an overload protection mechanism (spring or hydraulic system). When uncrushable hard foreign objects enter, the rollers automatically retract to discharge the obstruction. Normal operation resumes afterward, safeguarding the core components from damage.

2. Advantages

Eliminates metal contamination to ensure high purity of battery materials

This represents the most critical advantage of double-roll crushers when processing lithium ore. Lithium battery cathode materials impose extremely stringent requirements on metal impurities such as iron (Fe) and chromium (Cr). By utilizing non-metallic materials like zirconia rollers, the process ensures no metallic contaminants are introduced during crushing. This guarantees the purity of the final lithium concentrate, meeting the quality demands for battery-grade materials.

Precise particle size control and low over-grinding rate

The slow compression crushing method effectively minimizes the production of excessively fine powder while producing a more uniform output particle size. This is crucial for subsequent mineral processing steps (such as flotation), as uniform feed particle size significantly enhances mineral recovery rates.

Energy Efficiency and Environmental Protection

Double-roll crushers operate with high efficiency. Integrating them into grinding systems typically boosts output by 30%-40% while reducing overall energy consumption by 20%-30%. Equipped with dust-proof plates and excellent sealing, they effectively prevent dust leakage and operate at low noise levels, improving the working environment.
