What is a Mobile Jaw Crusher

1. Definition & Overview

A mobile jaw crusher is a portable crushing machine combining classic jaw - crushing principles with mobility. Engineered for on - site crushing in mining, construction, and recycling, it processes hard materials like granite and concrete blocks (compressive strength ≤ 300MPa) into 0–150mm aggregates, cutting transportation costs by over 60%.

Data Anchor: Global market reports show mobile jaw crushers held 42% of the crushing equipment market share in 2025, with an 18% annual growth rate (source: Global Market Insights).

2. Core Structure Breakdown

1. Jaw Plate System

1.High - manganese steel movable jaw (Mn13Cr2) + fixed jaw plate, driven by an eccentric shaft for 300 reciprocating squeezes/minute (e.g., our VCJ1070x760E model’s jaw plate lasts 8,000 hours).

2.Hydraulic wedge adjusts the discharge opening (50–200mm stepless adjustment) in 5 minutes.

2. Chassis System

Crawler version: 320mm - wide crawler + hydraulic leveling, climbing 35° slopes, ideal for Indonesian nickel mine mud (case: PT Vale uses our VCC300RS crawler crusher, saving $23,000/month in transportation).

2.Wheel - mounted version: 40km/h on highways, 7 - meter wheelbase for European rural roads (case: Our VCI1213F in the Berlin subway project, with 3 daily site transfers).

Intelligent System

Vibration sensor (±2% accuracy): Monitors jaw plate wear, giving 48 - hour warnings (Saudi NEOM project application reduced downtime losses by $150,000/year).

Diesel - electric hybrid: 18% less fuel use than pure diesel (CAT® 336E hybrid data from U.S. shale gas mining).

3. Working Principle

Material EntryVibrating feeder with iron remover feeds materials.

Primary Crushing: Movable jaw squeezes materials with 120–180mm stroke and 800–1,200kN force.

Particle Size Control: Wedge adjusts the discharge opening; oversized materials recycle (circulating crushing rate More than 5%).

Discharge: 85%+ cubical aggregates (20% better than traditional jaw crushers, meeting C50 standards).

4. Core Advantages

5. Global Cases

Case 1: South African Gold Mine

Pain: 30km granite transport costing $280/truck, 300 trucks/month.

Solution: Our VCJ1070x760E (180t/h) cut costs to $80/truck.

Quote: “Recovered cost in 6 months; 40% lower failure rate.” — AngloGold Ashanti ops manager.

Case 2: Indian Urban Renewal

Scenario: 1,200 tons/day concrete waste in Mumbai's Dharavi.

Solution: Our VCI1213F (150t/h, More than 85dB) made road - base aggregates.

Impact: Reduced landfilling by 60%, created 23 jobs/project — Mumbai Municipal Engineering.

Case 3: Norwegian Wind Power

Challenge: - 30℃ Arctic Circle startup issues.

Solution: Our VCC300RS low - temp version (heating oil bath) worked flawlessly on 200 wind sites.

Tech: IP67 bearings, - 40℃–50℃ range (DNV - certified in Northern Europe).

6. Technical Specs

7. Maintenance Guide

Jaw Plate Replacement: Quick - release (2 people, 4 hours). Replace at 1/3 wear (high - Mn steel lasts 2x longer).

Lubrication: High - temp (>35℃): Mobil SHC 634 every 200h. Cold - high (More than -10℃): Shell Alvania RL3 every 150h.

Smart Maintenance: Remote monitoring (e.g., cloud platform) with 92% predictive accuracy.

8. Industry Trends

Keywords: Mobile jaw crusher, crawler jaw crusher, construction waste equipment.

Future Tech:

2026 hydrogen - electric hybrid for zero - emission mines.

AI visual sorting with hyperspectral cameras.

3D - printed modular jaw plates (40% cost reduction).

9. Procurement Guide

TCO Model: Equipment (40%) + 5 - year fuel (35%) + maintenance (20%) + transport (5%).

Example: 180t/h model saves $1.87M over 8 years vs. fixed solutions.

Checklist:

✅ Material hardness (>200MPa needs high - Mn steel).

✅ Daily capacity (wheel - mounted <200t, crawler>300t).

✅ Site (crawler for mountains, low - noise wheel - mounted for cities).

✅ Certifications (CE MD for EU, BIS for India).

Conclusion

The mobile jaw crusher is a mobile aggregate production hub. From South African mines to Mumbai slums, it’s transforming workflows with mobility, intelligence, and durability. When crushing breaks free from location limits, every production link becomes more efficient and sustainable.
