Every cubic metre of structural concrete passes through a Sicoma twin shaft mixer. 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.
Twin-shaft machines reach full homogeneity in 30-40 seconds, keeping pace with the batching sequence.
Liners, arms and shaft seals are bolted in; no cutting or welding during routine replacement.
Large-opening gates with adjustable speed prevent segregation at discharge.
Discharge samples tested for strength variance typically fall below 5% across the batch.
Available as bare mixer, skip-fed unit, or mounted on a complete plant frame.
Planetary gear reducers with forced lubrication are selected for 24/7 duty cycles.
Indicative ranges for standard configurations. Final values are confirmed against your project requirements.

On typical projects this equipment is selected where output reliability governs the whole schedule.
Central mixing for ready-mix and project plants
Low-slump and colour-consistent concrete for moulded products
Planetary mixers for castables, ceramics and specialised mortars
Diesel-driven units with integrated weighing option
Dry-cast pan mixers feeding block-making machines




Six defined stages, each with named deliverables, so nothing is left to interpretation.
We start with your mix design, hourly output target, aggregate size, jobsite power supply and site layout — not with a catalogue page.
Our engineering team issues a layout drawing, foundation loads, power requirement and an equipment list matched to the target output.
A fixed specification quotation with clear technical annexes protects both sides; no vague "standard configuration" wording.
Weekly production photos, welding and pressure test records, plus third-party inspection if your project requires it.
Container or break-bulk shipment, then on-site supervision of assembly, alignment, calibration and dry-run.
Remote diagnostics by video call, spare parts dispatch within 48 hours for stocked items, and periodic return visits.
