Small rock crushers are essential equipment for construction, mining, and aggregate production in South Africa. These compact machines efficiently process hard rocks like granite, basalt, and quartz into usable aggregates for concrete, road base, and drainage materials.
The most widely used small crushers in South African markets include:
| Model | Feed Size | Capacity | Power |
|---|---|---|---|
| PE-250×400 Jaw Crusher | 210mm | 5-20t/h | 15kW |
| PCΦ400×300 Hammer Crusher | 100mm | 5-10t/h | 11kW |
| PG-Roller Crusher | 25mm | 2-10t/h | 7.5kW |
A typical small-scale crushing line consists of:
1. Vibrating feeder (GZD850×3000)
2. Primary jaw crusher (PE250×400)
3. Secondary impact crusher (PF1010)
4. Vibrating screen (3YK1237)
5. Belt conveyors system
Q: What’s the minimum investment for a small crusher plant?
A: Approximately R350,000-R800,000 depending on configuration.
Q: Can these crushers process recycled concrete?
A: Yes, most models can handle concrete waste with proper screening.
Q: What maintenance is required?
A: Monthly lubrication and wear parts inspection (hammers/jaws every 500-800 hours).
A local contractor installed a mobile PE250×400 jaw crusher with 3YK1237 screen to process demolition waste:
– Input: Concrete rubble (300mm max)
– Output: 0-5mm sand (30%), 5-20mm aggregate (50%)
– Production: 15t/h
– ROI
