lepidolite crusher(also known as double-roll crusher)， Huashengming double-roll crusher is a highly reliable and efficient choice for processing lithium mica ore. It is particularly suitable for the medium and fine crushing stages to produce uniformly sized feed material with low over-crushing rates for grinding preparation.

1. Working Principle
The working principle of the Huashengming double-roll crusher is highly efficient and intuitive:
It relies on two parallel rollers (one fixed and one movable) driven by an electric motor to rotate in opposite directions.
Lithium mica ore enters the crushing chamber formed between the rollers through the top feed opening, where it is continuously crushed by compressive and shear forces.
The discharge particle size is precisely controlled by adjusting the gap between the rollers via a hydraulic system or a wedge/shim adjustment mechanism.
Should uncrushable hard foreign objects (such as iron) enter the machine, the integrated hydraulic or spring overload protection system automatically retracts the rollers.
Once the foreign object is discharged, the system automatically resets, effectively safeguarding the machine’s core components from damage.
2.Advantages
Precise particle size control for optimized flotation efficiency:
The flotation efficiency of lithium mica is highly dependent on the particle size distribution of mineral grains.
Patented processes demonstrate that the sequence “jaw crusher for coarse grinding,
double-roll crusher for fine grinding” ensures lithium mica particle size distribution meets specific requirements of 40 mesh to 200 mesh and -200 mesh. This facilitates thorough interaction between clay-bearing iron lithium mica and flotation reagents,
achieving complete dispersion of the pulp solution and surface activation of the iron lithium mica.
Effectively reduces over-grinding rates:
The slow compression crushing method significantly minimizes the production of excessively fine powders.
Overly fine mineral slimes not only adsorb large amounts of flotation reagents, increasing costs, but also degrade the flotation environment,
adversely affecting concentrate grade and recovery rates.
Optional pollution-free configuration ensures product purity:
For applications demanding stringent metal contamination control in lithium mica concentrates (e.g., battery materials),
the roll crushers’ rollers and material-contacting components can be fabricated from non-metallic or corrosion-resistant materials like zirconia or SUS304 stainless steel.
This prevents contamination from iron and other impurities, guaranteeing final product purity.
Simple structure with energy efficiency and environmental protection:
The relatively simple structure facilitates maintenance.
Integrating a double-roll crusher into the grinding system maximizes the production capacity of grinding equipment,
typically increasing output by 30%-40% while reducing total energy consumption by 20%-30%.
Equipped with dust-proof plates and excellent sealing performance, it effectively prevents dust leakage and operates with low noise levels.
Summary
The Huashengming double-roll crusher is fully capable of serving as crushing equipment for lithium mica ore.
It demonstrates exceptional performance during the medium and fine crushing stages,
particularly when high demands exist for uniform output particle size and control over over-crushing rates.
