Advantages and Configuration of Limestone Crushing Production Line in Papua New Guinea
Equipment: Jaw crusher + impact crusher + closed-circuit screening
Place of use: Papua New Guinea
Processed material: Limestone
Input size: 500 mmOutput size: 0–5/5–20/20–31.5mm
Capacity : 200 tph
Process Adaptation: “Pre-screening followed by crushing + closed-loop circulation”.
The feeder pre-screens soil and fine materials first, preventing high-moisture mud from entering the crushing chamber and causing blockages.
Jaw crusher for coarse crushing + impact crusher for medium and fine crushing: The impact crusher is most efficient for soft materials, with less over-crushing and controllable powder ratio.
Closed-loop screening: Oversized materials are automatically returned to the crusher; the finished product has a stable gradation of 0–31.5mm, a high proportion of cubic particles, and <10% of needle-like and flaky particles, meeting local construction standards.
Comparison with hammer crusher: Less powder, less blockage, and a 30%+ higher operating rate during the rainy season.
This jaw crusher + impact crusher + closed-circuit screening configuration is tailor-made for Papua New Guinea's high temperature and humidity, long rainy season, complex terrain, weak maintenance, and difficulty in obtaining spare parts: it is anti-clogging and moisture-resistant, has good particle shape, stable production capacity, low maintenance, easy installation, compliance and cost-effectiveness, and is most suitable for local limestone processing.
