Small-scale mineral dressing lines (50-200TPH) are widely used in small and medium-sized metal mines and non-metal mines. Reasonable equipment selection is the key to ensuring the stable operation of the production line, reducing investment and improving economic benefits. This guide will provide reference for the equipment selection of small-scale mineral dressing lines.
### Selection Principles
1. Adaptability: The selected equipment should be suitable for the characteristics of raw materials (ore grade, mineral composition, hardness, moisture content) and finished product requirements (concentrate grade, recovery rate).
2. Economy: Under the premise of meeting production needs, select equipment with low investment, low energy consumption and low maintenance cost, and avoid blind pursuit of high-end equipment.
3. Operability: The selected equipment should be simple to operate, easy to maintain, and suitable for the professional level of local workers, reducing the cost of personnel training.
4. Stability: Select equipment with mature technology and stable performance, with low failure rate, to ensure the continuous operation of the production line.
### Equipment Selection for Different Mineral Types
1. Gold Ore: For small-scale gold ore dressing lines, adopt "jaw crusher + impact crusher + gravity separation equipment" (shaking table, spiral classifier). Gravity separation equipment is simple, environmental friendly and low-cost, suitable for small-scale gold mines with medium to high ore grade.
2. Copper Ore: For small-scale copper ore dressing lines, adopt "jaw crusher + hydraulic cone crusher + flotation machine (simple type)" or "jaw crusher + hydraulic cone crusher + gravity separation equipment", which can be selected according to the mineral composition of copper ore.
3. Iron Ore: For small-scale iron ore dressing lines, adopt "jaw crusher + hydraulic cone crusher + spiral classifier + shaking table", which adopts gravity separation process, simple process and low investment, suitable for small-scale iron mines.
### Key Notes
When selecting equipment, it is necessary to consider the on-site power supply, space and other conditions, and select equipment with appropriate specifications. At the same time, select supporting equipment such as vibrating feeders, belt conveyors and dust removal equipment to ensure the integrity of the production line.
