3. Actual Output Analysis
3.1 Theoretical vs. Actual Output
| Indicator | Value |
| Theoretical Output | 120m³/h（60batches×2m³） |
| Actual Output | 84-96m³/h（70%-80%efficiency） |
3.2 Factors Affecting Output
– Transport scheduling: Time taken for mixer trucks to enter and exit
– Underutilized capacity: Batches not consistently full
– Maintenance: Daily cleaning required to prevent material buildup
4. Selection Recommendations
4.1 Applicable Scenarios
– Commercial concrete plants: Recommended 4 × 100 t silos for continuous production
– Engineering projects: 5 × 100 t silos for remote sites with limited transport access
– Special projects (high-speed rail/nuclear power):Requires weighing accuracy of ±1%
4.2 Comparison with HZS90/HZS180
| Model | Batch Capacity | Theoretical Output | Applicable Scale |
| HZS90 | 1.5m³ | 90m³/h | Small to medium projects |
| HZS120 | 2m³ | 120m³/h | Medium commercial plants (large projects) |
| HZS180 | 3m³ | 180m³/h | Medium commercial plants (large projects) |
5. Frequently Asked Questions
5.1: What is the footprint of the HZS120 plant?
– Linear layout: ≈55 m × 20 m (includes aggregate storage, host, control room)
– Compact design: Reducible to 45 m × 20 m (elevated batching storage, shorter conveyor)
5.2: What is the service life of the JS2000 mixer?
– Key component lifespan:
– Liners/blades: 150,000–200,000 m³
– Reducer: 5–8 years (regular oil changes)
– Motor: 10+ years (IP54 protection)
3: How to increase the output of HZS120?
– Optimization measures:
1. Install waiting hopper (reduces cycle time by 5–8 seconds)
2. Use high-capacity transport vehicles to reduce frequency
3. Add screening for regions with inconsistent aggregate size
6. Maintenance Guidelines
6.1 Daily Checks
– Mixing blade wear (adjust if gap > 5 mm)
– Belt conveyor alignment
– Electric oil pump clogging
6.2 Weekly Maintenance
– Sensor calibration (ensure weighing accuracy)
– Roller and belt wear inspection
6.3 Quarterly Servicing
– Reducer gear oil replacement
– Electrical cabinet wiring aging check
Conclusion
The HZS120 concrete batching plant is the preferred choice for medium-to-large commercial concrete plants due to its high output, precision, and low failure rate. For detailed quotations or customized solutions, please contact professional manufacturers.
