Guide de la capacité de la mâchoire et de la taille de la sortie pour les opérations de carrière
Jaw crushers are indispensable in quarrying operations for primary crushing, transforming large rocks into manageable aggregates. Understanding how to optimize theircapacité and controloutput size is critical for maximizing productivity and meeting project specifications. Ci-dessous, we break down the key factors influencing performance and provide actionable insights for operators.

Key Factors Determining Jaw Crusher Capacity
1. Feed Opening Dimensions
The width and depth of the feed opening directly impactcrushing capacity. Par exemple, un 860×1,100 mm jaw crusher can typically process 200-500 tph of limestone, while granite, which is a rock with higher hardness, can reduce this ratio by 30%. So we can choose a hard rock crusher to process granite so that we can get a satisfactory production capacity.

2. Caractéristiques du matériau
Rock hardness (measured by Échelle de Mohs), abrasiveness, and moisture content significantly affectquarry crusher output:
- Soft sedimentary rocks (Par exemple, grès): 15-25% higher throughput
- Igneous rocks (Par exemple, basalte): Nécessite 20-40% more power
3. CSS (Closed Side Setting) Adjustments
The minimum distance between jaw plates determines yourfinal output size:
CSS Setting | Typical Output Size | Capacity Impact |
---|---|---|
100 millimètre | 150-200 millimètre | Maximizes throughput |
50 millimètre | 75-100 millimètre | Reduces capacity by 25% |
25 millimètre | 35-50 millimètre | Capacity drops 40-50% |
Calculating Output Size in Quarry Applications
Use this formula to estimatejaw crusher product size:
P80 = 0.8 x CSS + (Feed Size x 0.2)
Example: For 150 mm feed material with 75 mm CSS
P80 = 0.8*75 + (150*0.2) = 60 + 30 = 90 millimètre

Optimizing Production: 3 Proven Strategies
1. Match Crusher Size to Quarry Requirements
Select jaw crushers with 20-30% higherrated capacity than your target production to account for material variability.
2. Implement Gradation Control
Use scalping screens before crushing to remove fines, increasing effectivecrushing chamber capacity by 15-20%.
3. Monitor Wear Patterns
Worn jaw plates increase the actual CSS by 10-25%, causing oversized output. Donc, implement monthly measurements withcrusher profile gauges.

Étude de cas: Granite Quarry Output Optimization
A Texas quarry increased production by 18% après:
- First, adjusting CSS from 125 mm to 90 millimètre
- Installing pre-screening for >200 mm boulders
- Switching to corrugated jaw plates

Common Mistakes in Capacity Planning
- Ignoring material bulk density variations (1.6 t/m³ vs 2.8 t/m³)
- Overlooking crusher discharge conveyor limits
- Failing to account for daily temperature-induced metal expansion
Advanced Tools for Precision Control
Modern solutions enhancingjaw crusher output management:
- Laser CSS measurement systems (±0.5 mm accuracy)
- Automomatic wear compensation software
- Real-time throughput monitoring dashboards

Maximize Your Quarry’s ROI
By mastering yourjaw crusher’s capacity and output size relationships, quarries can achieve 15-30% higher yields. Donc, keep in mind that the optimal settings will vary from day to day depending on material mix and wear rate. Aussi, combine these guidelines with regular equipment audits and operator training to achieve continued success in the competitive aggregates market.
