Gold ore crushing choose roll crusher, effectively improve the efficiency of gold beneficiation. Roll crusher does have significant advantages in gold ore beneficiation, its high efficiency, energy saving, controllable characteristics are especially suitable for processing gold ore such as high-value ores. The following are specific analyses:
Gold ore crushing choose roll crusher
1. Precise particle size control, improve beneficiation efficiency
Adjustable discharge size: Roll crusher can precisely control the finished product size by adjusting the roller gap (usually 2-10mm). For example, by optimising the roll crusher, China Gold Xinjiang Jintan Mining has reduced the crushing size from 12mm to 8mm, achieved ‘more crushing and less grinding’, and increased the daily processing capacity by 5%.
Reducing over-crushing: The roller crushing principle is mainly based on extrusion, compared with impact crushing, it can effectively reduce over-crushing phenomenon, retain more intact gold particles, and avoid the loss of fine gold particles in the subsequent flotation or cyanidation process. The practice of Jintan Mining shows that the gold recovery rate is increased to 92% after optimising the crushing size.
2. High adaptability and processing efficiency
Compatible with complex ores: The roll crusher is suitable for both dry and wet materials, and can process gold ores with high mud content. Its double-roll structure can crush medium and high hardness ores (e.g. quartz vein gold ore), and the wear resistance is enhanced by high-strength alloy rollers.
High efficiency and energy saving: The dual motor drive design is powerful and reduces energy consumption by 45% with the same capacity. The crushing process in gold ore dressing accounts for more than 30% of the overall energy consumption, and the energy saving effect directly reduces the production cost.

3. Stable operation and low maintenance cost
Sealing, dustproofing and noise reduction: Built-in dust-resistant boards and noise reduction devices reduce dust spillage and noise pollution, which meets the requirements of environmental protection. Gold smelting is sensitive to the environment, this feature is conducive to maintaining a clean production environment.
Easy maintenance and durability: the rollers can be welded after wear and used repeatedly, with a life span of more than one year, reducing the frequency of replacement of wearing parts and downtime losses. Hydraulic rollers are also equipped with an automatic overload protection function to reduce the failure rate.
4. Actual application cases
Shandong Gold Sanshandao Gold Mine: adopting the whole process intelligent crushing system, the roller crusher with unmanned transport and automatic plant, to achieve ‘mechanisation for man’, selected as the provincial digital transformation demonstration project.
Xinjiang Jintan Mining: through the transformation of the crushing system (particle size of 8mm), the recovery rate of flotation was increased from 85% to 92%, with a significant increase in annual efficiency.
With precise particle size control, high adaptability and low operating costs, the roll crusher has become the preferred equipment for gold ore beneficiation, and is especially suitable for modern mines pursuing high recovery rates and low energy consumption. Practical cases have proved that it can increase the processing capacity by more than 5% and the recovery rate exceeds 90%, with remarkable comprehensive benefits.
