Shaking tables are one of the most widely used gravity separation equipment for minerals such as tungsten, tin, gold, lead-zinc and other rare metals. They feature high separation accuracy, stable enrichment ratio and simple operation, especially suitable for fine mineral separation and purification.
Many customers only focus on price or appearance when selecting equipment, ignoring the matching degree with their own ore properties and production process, resulting in low recovery rate and unsatisfied concentrate grade. In fact, there is no absolute "best" shaking table—suitability is the most important.
1. Choose According to Particle Size
Different particle sizes require different types of shaking tables:
- Coarse particles (>0.2 mm): Coarse sand shaking tables, with large stroke and higher processing capacity.
- Medium-fine particles (0.074–0.2 mm): Fine sand shaking tables, balancing accuracy and efficiency, the most commonly used type.
- Micro-fine particles / slime (<0.074 mm): Slime shaking tables, with finer bed surface structure to reduce fine mineral loss.
2. Choose According to Production Process
- Roughing & scavenging: Prioritize processing capacity to quickly remove tailings.
- Cleaning: Focus on high concentrate grade, suitable for high-precision shaking tables.
- Large-scale production: Can be used with jigs, spiral chutes and other equipment to form a complete gravity separation plant.
3. Choose According to On-site Conditions
- Determine the number of units based on daily processing capacity.
- For limited space, multi-layer shaking tables help save floor area.
- Stable structure, easy maintenance and flexible adjustment are preferred for long-term use.
4. Avoid Common Mistakes
- Only comparing prices without considering bed material, workmanship and service life.
- Lack of classification before feeding, leading to poor separation.
- Using fixed parameters for a long time without adjustment.
- Using beyond the applicable scope, especially for minerals with small density difference.
Conclusion
To choose the right gravity separation shaking table, the key is to match particle size, process and site conditions. Based on practical ore properties and realistic needs, scientific selection can stably improve recovery rate and concentrate grade, and maximize the value of the equipment.
Scientific selection brings efficient separation.
