Lithium ore and chrome ore crusher (also known as double-roll crusher) offers both technical feasibility and economic advantages in the crushing of lithium ore and chromite ore.

Lithium Ore And Chrome Ore Crusher

1. Working Principle

The double-roll crusher primarily crushes materials by squeezing and grinding them between two counter-rotating rolls. When lithium ore enters the crushing chamber through the top feed opening between the rolls, it undergoes high-pressure compression and shear forces to achieve fragmentation. This relatively “gentle” crushing method offers significant advantages in lithium battery material processing.

2.Advantages

Eliminates metal contamination, ensuring high purity of battery materials

This is 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). Traditional crushers using metal rollers like manganese steel inevitably introduce trace metal contamination. Double-roll crushers, however, can employ ceramic or zirconia rollers to ensure no metallic impurities enter during crushing. Case studies demonstrate that using ceramic double-roll crushers can reduce iron content in cathode materials from over 100 ppm to below 5 ppm.

Precise and Controllable Particle Size to Meet Specific Process Requirements

The discharge particle size can be easily controlled by precisely adjusting the gap between the two rollers via a hydraulic system or mechanical device. This is crucial for subsequent mineral processing or chemical reactions, as uniform particle size distribution enhances reaction efficiency and product consistency.

Energy-efficient and environmentally friendly production

Featuring a low-speed, high-torque design, the double-roll crusher consumes less energy than traditional ball mills. Additionally, the equipment typically employs a fully sealed structure with dust extraction interfaces, effectively preventing dust leakage to safeguard the working environment and meet environmental standards.
