Overview
The Avelta AVL-CBP Concrete Batching Plant is a stationary, compulsory-mix concrete production system engineered for civil construction teams that demand consistent mix quality, high throughput, and reliable uptime on demanding road, bridge, and infrastructure projects. Designed for procurement engineers and plant managers who must justify capital expenditure against production schedules, the AVL-CBP range spans theoretical outputs from 25 m³/h for smaller site installations up to 160 m³/h for large highway corridors, ready-mix supply operations, and major civil works requiring continuous pour capability around the clock.
The plant operates on a fully computerised closed-loop batching cycle: aggregates are drawn from multi-compartment feed bins through individual weigh hoppers, cementitious materials are extracted from pressurised silos via sealed screw conveyors and weighed independently, and water with liquid admixtures is metered to ±0.5% accuracy before all constituents are simultaneously discharged into a high-shear twin-shaft compulsory mixer. The twin-shaft design ensures homogeneous blending of stiff, lean, and self-compacting mixes in a 45–75 second cycle, achieving uniformity that gravity-drum or transit-mix drum loading alone cannot reliably deliver for structural-grade concrete used in pavement slabs, bridge decks, and reinforced works.
Avelta engineering discipline is expressed in the plant's structural robustness — hot-rolled steel frame members, flanged bolt-together assembly for rapid erection and re-siting — and in the control architecture, where a PLC-based industrial computer with touch-screen HMI stores multiple concrete recipes, logs every batch by timestamp and truck ticket, and can be configured for remote monitoring via LAN or cellular link. Avelta backs every CBP unit with in-country commissioning, operator training, and a stocked genuine-parts programme, so that customers on international road projects are not exposed to long lead times for critical wear components.

Working Principle
How the Concrete Batching works
- 01
Aggregate Receiving and Storage
Coarse and fine aggregates are loaded into a multi-compartment feed bin assembly — standard four-compartment units hold 12–32 m³ in total — by wheel loader or belt conveyor from on-site stockpiles. Individual compartment gates allow each fraction to be drawn independently without cross-contamination.
- 02
Aggregate Weighing and Conveying
An inclined collecting belt conveyor draws each aggregate fraction in sequence through pneumatically actuated radial gates onto a suspended weigh hopper supported by digital load cells. The PLC accumulates aggregate fractions against the recipe target and closes each gate when the correct mass is reached, achieving weighing accuracy within ±2% of the target mass.
- 03
Cementitious Material Batching
Cement, fly ash, or ground granulated blast-furnace slag held in pressurised bulk silos is extracted by enclosed flighted screw conveyors directly into a dedicated cement weigh hopper. Separate weigh hoppers for each cementitious material prevent recipe contamination and allow multi-binder mixes to be batched simultaneously, with accuracy held to ±1%.
- 04
Water and Admixture Dosing
Mixing water stored in a sealed overhead tank is metered into the water weigh hopper by a butterfly valve and electromagnetic flow meter to ±0.5% precision. Liquid admixtures — plasticisers, retarders, accelerators — are individually dosed by peristaltic pumps from dedicated 200–600 litre stainless-lined tanks mounted on the plant's upper deck, with each admixture metered to its recipe proportion by weight or volume.
- 05
Compulsory Twin-Shaft Mixing
All weighed constituents are discharged simultaneously into the twin-shaft compulsory mixer. Contra-rotating shafts fitted with replaceable mixing arms and liners work the charge in a high-shear planetary pattern, achieving full homogeneity typically within 45–75 seconds regardless of mix stiffness or aggregate maximum size up to 80 mm.
- 06
Discharge and Truck Loading
On completion of the mixing cycle the PLC-controlled discharge gate opens and the finished concrete falls by gravity into the body of a waiting transit mixer, dump truck, or pump hopper positioned below the mixer outlet. A concrete discharge chute with sealed dust skirt directs the material cleanly and minimises segregation during transfer.
- 07
Production Logging and Reporting
The control system automatically records each batch — timestamp, truck ID, recipe code, actual weights batched versus target, cumulative daily and project volumes — and prints a delivery docket per batch. Data is stored on-board and can be exported via USB or network link for ERP integration, QA records, or remote project management oversight.
Engineered Advantages
Why buyers specify the Avelta CBP.
High-Intensity Compulsory Mixing
The twin-shaft design with hardened alloy mixing arms and segmented liner plates delivers short, uniform mixing cycles across stiff paving mixes, self-compacting concrete, and structural grades — performance that free-fall drum systems cannot replicate at equivalent cycle times.
Multi-Point High-Accuracy Weighing
Independent load-cell weigh hoppers for aggregates, each cementitious material, and water — with electromagnetic admixture metering — mean every batch is traceable to recipe with an auditable data record, satisfying quality-assurance requirements on government and donor-funded road contracts.
Modular Bolt-Together Structure
The plant ships in bolt-connected steel modules dimensioned for standard flat-rack or open-top containers, reducing freight cost and enabling site erection with a mobile crane and a small skilled crew in three to five days without heavy civil foundations for most models.
Recipe-Managed PLC Control with Production Reporting
The batching computer stores hundreds of concrete recipes, prints a batch docket for every load, accumulates daily and project volume totals, and supports export of production data for project management systems — reducing manual recording errors and supporting materials reconciliation on large contracts.
Dust-Contained Cement Circuit
Enclosed screw conveyors, pressurised silo aeration, and a pulse-jet bag filter on the cement weigh hopper circuit contain fugitive cement dust to levels consistent with urban site operation, protecting operator health and reducing material waste on site.
Rapid-Change Wear Parts
Mixing arms, liner plates, and shaft oil seals are designed for tool-only replacement without removing shafts, bringing planned maintenance time to under two hours for a full liner change and minimising production downtime between pours.
Avelta Export Commissioning and Training Package
Every AVL-CBP unit is supplied with factory-acceptance testing records, a commissioning engineer dispatched to site for startup and calibration, and structured operator and maintenance training — supported by a stocked spare-parts programme so that critical wear items are available without airfreight lead times.
