Small/Mini Concrete Batching Plant

Small/Mini Concrete Batching Plant: Compact Efficiency for High-Value Concrete Production

1. PAIN-POINT DRIVEN OPENING

Are you facing rising operational costs due to inefficient concrete batching at remote or low-volume sites?
Are frequent equipment mobilizations consuming 15–20% of your project timeline and increasing labor overhead?
Is inconsistent mix quality leading to rework, with field testing showing up to 12% variance in compressive strength across batches?
Do space constraints at urban job sites limit your ability to deploy traditional batching infrastructure?
Are rental costs for temporary batching solutions exceeding $8,000/month per location with limited control over output?

If these challenges impact your project margins or delivery timelines, could a purpose-built Small/Mini Concrete Batching Plant offer a scalable, cost-controlled alternative?

2. PRODUCT OVERVIEW

The Small/Mini Concrete Batching Plant is a modular, skid-mounted concrete production system designed for output volumes between 15 and 60 m³/hour. Engineered for rapid deployment and minimal site footprint, it supports precise batching of ready-mix concrete for targeted applications where full-scale plants are impractical.

Operational Workflow:

1. Material Feeding: Aggregates are loaded via front-end loader into calibrated aggregate bins; cement and supplementary cementitious materials (SCMs) are pneumatically conveyed from silos.
2. Weighing & Metering: Load cells and loss-in-weight systems ensure ±1% accuracy across all raw materials.
3. Mixing Cycle: A twin-shaft mixer delivers homogenous concrete in 30–45 seconds per batch.
4. Discharge: Mixed concrete is discharged directly into transit mixers, pump hoppers, or batching trucks.
5. Control & Monitoring: PLC-based control panel with touchscreen HMI enables recipe management, batch tracking, and diagnostics.

Application Scope:

• Urban construction projects with space limitations
• Remote infrastructure (roads, bridges, rural housing)
• Pre-cast yard support
• Repair and rehabilitation works
• Temporary project-specific batching needs

Limitations:
Not intended for continuous high-volume production (>60 m³/hour) or large-scale ready-mix commercial supply chains requiring multiple simultaneous mix designs.

6. APPLICATION SCENARIOS

Urban High-Rise Foundation Work

Challenge: Limited laydown area on a downtown construction site restricted access for central plant trucks; pump delays caused average wait times of two hours per pour. Rework due to inconsistent slump reached $23,000 over three months.
Solution: Deployed a mobile Small/Mini Concrete Batching Plant on-site footprint of just . Automated batching matched pump feed rate at . Integrated slump control reduced variability.
Results: Eliminated trucking delays; achieved consistent slump within ±½ inch; reduced rework costs by $18,700 over six weeks; improved pour scheduling accuracy by >90%.

Rural Road Infrastructure Project

Challenge: Remote highway segment required daily delivery of ~35 m³ of concrete over five months. Central plant deliveries incurred average fuel/labor costs of $68/m³ due to round-trip distances exceeding . Quality issues led to failed cylinder tests in two batches.
Solution: Installed a containerized Small/Mini Concrete Batching Plant at mid-project location using local aggregates and bulk cement supply. Operated two shifts daily with one trained technician.
Results: Reduced transportation cost by $42/m³ ($79,800 total savings); achieved zero failed cylinder tests post-deployment; completed paving schedule three days ahead of plan.

Pre-Cast Yard Support Operation
