Concrete Mixers
on site concrete mixers
Every cubic metre of structural concrete passes through a on site concrete mixers. The machine has one job — distribute cement paste evenly around every aggregate particle in the shortest possible cycle — and when it fails, the failure shows up as strength scatter, segregation during pumping or rejected truckloads.
Wear is the real operating cost. Shaft-end seals, liner plates and mixing arms are therefore designed as replaceable assemblies, dimensioned so that maintenance crews can change them on site within a single shift.
Buyers usually compare two things: whether the machine will hold its rated output on a hot day with damp aggregates, and whether anyone will answer the phone in year three. HAMAC designs for both.
Key Advantages of on site concrete mixers
Replaceable wear assemblies
Liners, arms and shaft seals are bolted in; no cutting or welding during routine replacement.
Heavy-duty gearboxes
Planetary gear reducers with forced lubrication are selected for 24/7 duty cycles.
Homogeneity measured, not claimed
Discharge samples tested for strength variance typically fall below 5% across the batch.
Optional tilt/hoist configurations
Available as bare mixer, skip-fed unit, or mounted on a complete plant frame.
Short cycle times
Twin-shaft machines reach full homogeneity in 30-40 seconds, keeping pace with the batching sequence.
Hydraulic or pneumatic discharge
Large-opening gates with adjustable speed prevent segregation at discharge.
Technical Parameters
Indicative ranges for standard configurations. Final values are confirmed against your project requirements.

Typical Applications
On typical projects this equipment is selected where output reliability governs the whole schedule.
Precast factories
Low-slump and colour-consistent concrete for moulded products
Remote areas without grid power
Diesel-driven units with integrated weighing option
Block and paver yards
Dry-cast pan mixers feeding block-making machines
Batching plants
Central mixing for ready-mix and project plants
Refractory and chemical plants
Planetary mixers for castables, ceramics and specialised mortars
From Enquiry to Commissioning
Six defined stages, each with named deliverables, so nothing is left to interpretation.
Requirement study
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Scheme design
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
Quotation & contract
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Production & inspection
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Delivery & installation
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
After-sales
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
Frequently Asked Questions about on site concrete mixers
Can you supply only the mixer to retrofit an existing plant?
Yes. We supply bare mixers with mounting frames, gate actuators and control interfaces for third-party plants.
How often should liners be replaced?
Typically after 60,000-100,000 batches for a twin-shaft mixer using rounded aggregate; angular or highly abrasive aggregate shortens that.
Twin-shaft or planetary?
Twin-shaft wins on throughput and simple maintenance for ready-mix volumes; planetary gives superior homogeneity for low-slump, coloured or fibre-reinforced mixes and is preferred in precast.
How do I size the mixer to my plant output?
Match batch size to the plant.s rated hourly output divided by the number of batches per hour — normally 40-50 for a twin-shaft installation.
Is a moisture probe included?
Yes — microwave moisture sensing with automatic water correction is standard on plant-mounted units.
