30-50tph Portable Mobile Jaw Crusher 250x400: Ideal Solution for Small Quarries

For small-scale quarry operators, construction contractors, and mineral processors, finding a cost-effective, flexible crushing solution is critical to profitability. The 30-50tph portable mobile jaw crusher with 250x400mm opening combines compact design, reliable performance, and exceptional mobility to tackle diverse crushing tasks.

Main Specification Of Portable Mobile Jaw Crusher 250x400

1. Jaw Opening: 250mm × 400mm (9.8” × 15.7”), accommodating maximum feed size up to 210mm​
2. Capacity Range: 30-50 tons per hour (tph), perfectly matched to small quarry production needs​
3. Power Option: 15-22kW electric motor or diesel engine (for off-grid sites)​
4. Weight: 2.5-3.5 tons, enabling easy transportation via pickup truck or small trailer​
5. Discharge Adjustment: 20-60mm adjustable output, supporting versatile aggregate sizes (e.g., 10-20mm road base, 20-40mm concrete aggregates)​

Unlike fixed crushing plant that require extensive site preparation, this portable unit integrates the 250x400 jaw crusher, vibrating feeder, belt conveyor, and control system onto a single mobile chassis. This all-in-one design eliminates the need for separate installations, cutting setup time to just 30 minutes per site.

Key Advantages for Small Quarry Operations

1. Unmatched Mobility & Flexibility​
The portable design lets operators move directly to the material source, slashing raw stone transportation costs by 40-60% vs. fixed plants. Its compact footprint (4m × 2m × 2.8m) fits tight spaces—urban sites, narrow quarries, or mountainous areas—while optional 4x4 tires/tracks enhance off-road maneuverability. Relocation between sites is fast with minimal downtime.​

2. Cost-Efficiency & Quick ROI​
Ideal for small businesses: 50-70% lower initial investment than medium-scale lines (no foundation/civil works needed); 15kW low power consumption; high-chromium jaw plates (2x longer lifespan, 3-6 months) reduce replacements. Most users see ROI in 6-12 months.​

3. Robust Performance for Diverse Materials​
Despite its size, the deep crushing chamber and 1:8 crushing ratio handle Mohs 5-7 materials (limestone, granite, basalt), construction waste, river stones, and industrial ores. A rugged steel frame and sealed bearings withstand dusty/rainy conditions, with 95% product qualification rate in real-world use.​

4. Easy Operation & Low Maintenance​
User-friendly controls let operators adjust discharge size and monitor performance with minimal training. Maintenance is simple: quick-access jaw plates, centralized lubrication, and easy conveyor adjustments.

Tips for Maximizing Performance of Your 250x400 Mobile Crusher​

To ensure optimal output and longevity, follow these practical tips:​
1.Control Feed Size: Avoid rocks larger than 210mm—use a pre-screen for oversized chunks​
2.Adjust Discharge Wisely: Set gap to 30-40mm for 30-50tph; narrower gaps (20mm) improve uniformity but reduce output​
3.Regular Maintenance: Check jaw plate wear every 20 hours, lubricate bearings weekly, and clean screens (critical for wet materials)​
4.Match Power to Application: Diesel for off-grid sites; electric for stable power supply

The 30-50tph portable mobile jaw crusher 250x400 is the ultimate solution for small quarries and contractors seeking flexibility, affordability, and reliability. Its compact design, versatile performance, and low operating costs make it ideal for crushing limestone, construction waste, and minerals.
