Concrete Batching Machine Guide: 5 Features for Precision Dosing
In the world of concrete production, the batching machine is the gatekeeper of quality. Even the most advanced JS-series twin-shaft mixer cannot compensate for inaccurate aggregate dosing. For project managers in high-stakes environments—from Riyadh’s heat to Southeast Asia’s humidity—precision isn't just a preference; it’s a requirement for structural compliance.
Xingye Machinery’s PLD-series batching machines are engineered to solve the most common site pain points: weighing drift, material sticking, and belt slippage. Here are the five technical features that define our high-performance dosing systems.
1. Dual-Speed "Coarse and Fine" Weighing Logic
To balance high-speed production with millimetric precision, our systems utilize a two-stage weighing process. The "coarse" feed handles 90% of the material at high volume, while the "fine" feed trickles the remaining 10% to hit exact weight targets.
- The Benefit: Eliminates the "overshoot" common in single-speed vibratory feeders.
- Impact: Ensures the water-cement ratio remains stable, protecting the concrete’s compressive strength.
2. High-Sensitivity Load Cells and Stability
We integrate premium pressure sensors (load cells) that maintain ±1% to ±2% accuracy even in high-vibration environments. These sensors are protected by robust housing to prevent dust ingress and moisture interference—critical for sites in tropical or coastal regions.
3. Intelligent Material Flow Management
One of the biggest bottlenecks in batching is "sand hanging"—where damp sand sticks to the bin walls. We address this through two specific engineering choices:
- Wall-Mounted Vibrators: Specifically installed on the sand bins and weighing buckets to ensure rapid, clean discharge.
- Steep-Angle Hopper Design: Optimized geometry to facilitate gravity flow for a variety of aggregate sizes.
4. Advanced Conveyor Reliability
The transition from batcher to mixer is a common point of failure. Our belt conveyors feature:
| Feature | Technical Function | Operational Advantage |
|---|---|---|
| Screw Tensioning Device | Adjustable tail-end tension | Prevents belt slippage and tracking issues |
| Head Blocking Cover | Material containment shroud | Reduces spillage and site cleanup labor |
| Reinforced Rigidity | Heavy-duty steel frame | Prevents frame warping under full 4-bin loads |
5. Multi-Aggregate Flexibility
Modern infrastructure projects often require complex mixes involving 3 to 4 types of aggregate (sand, fine gravel, coarse stone). Our PLD units allow for simultaneous weighing of up to four materials, significantly reducing the batch cycle time compared to cumulative weighing systems.
Technical Specifications Overview
Whether you are looking for a compact unit for an HZS25 plant or a high-capacity system for an HZS180 project, our specifications meet global standards:
- Weighing Accuracy: ±2% (Aggregates)
- Bin Capacity: Customizable from 0.8m³ to 5m³ per bin
- Control System: Fully automated with manual override
