The Full HZS Range — How the Model Number Works
The number in an HZS model is its theoretical output in cubic metres per hour, so an HZS120 is a 120 m³/h plant and an HZS60 is 60 m³/h. Two things change as you move up the range: the mixer size, and the batching reserve behind it. Weighing accuracy does not change — it is ±2% on aggregate and ±1% on cement, water and admixture across the whole range.
| Model | Output | Mixer | Aggregate bins | Total power | Indicative FOB price | Typical use |
|---|
| HZS60 | 60 m³/h | JS1000 | 3 × 15 m³ | ~110 kW | $48,000 – $75,000 | Medium housing, small bridges |
| HZS90 | 90 m³/h | JS1500 | 4 × 20 m³ | ~150 kW | $65,000 – $100,000 | Highways, larger buildings |
| HZS120 | 120 m³/h | JS2000 | 4 × 25 m³ | ~190 kW | $85,000 – $130,000 | Ready-mix supply, large sites |
| HZS180 | 180 m³/h | JS3000 | 4 × 30 m³ | ~260 kW | $120,000 – $180,000 | Dams, airports, infrastructure |
| HZS240 | 240 m³/h | JS4000 | 4 × 40 m³ | ~400 kW | $250,000 – $400,000 | Large ready-mix plants, major infrastructure |
Prices are indicative FOB China and depend on configuration, silo count and control system. Sizing question? Match the plant to your peak daily pour, not your average — a plant sized to the average will bottleneck every busy week. Tell us your project and we will recommend the model.
One HZS240, or Two HZS120? The Decision Most Buyers Face
At this size the honest comparison is not against a bigger plant — it is against two HZS120s. The capital numbers are closer than buyers expect, and the right answer depends on how you value downtime rather than on which plant is more modern. If the capital decision is the constraint, our notes on batching plant financing options set out the usual structures.
| One HZS240 | Two HZS120 |
|---|
| Indicative plant cost | $250,000 – $400,000 for one plant | $85,000 – $130,000 each, so $170,000 – $260,000 for the pair |
| Batch size | 4 m³ per batch — fewer truck exchanges per cubic metre, which is what large continuous pours actually need | 2 m³ per batch — more exchanges per cubic metre |
| Installed power | ~400 kW in one load | ~190 kW each, ~380 kW combined — similar total, but distributed |
| Redundancy | Single point of failure. A mixer or gearbox failure stops all output. | If one plant stops, you keep producing at half rate instead of zero |
| Footprint and civil works | One large foundation, one high-capacity aggregate feed | Two smaller foundations, more total yard area, two control points |
| Spares and maintenance | One set of JS4000 wear parts (spare parts guide) | Two sets of JS2000 wear parts, two maintenance schedules |
| Operations | One control room, one operator per shift | Two control rooms or one centralised — in practice two operators at peak |
The rule of thumb we give buyers: choose the HZS240 when the product is large single pours and the cost of a stoppage is measured in pour quality — a cold joint in a dam or a raft is not a delay, it is a defect. Choose two HZS120s when the contract mixes many smaller pours and the buyer values continuity over batch size, because a plant that is running at half rate still delivers. If your market is ready-mix supply with a few very large customers, one HZS240 with a well-stocked wear-parts kit is usually the better commercial decision; if you are bidding public works where the penalty clauses are severe, the redundancy argument wins more often than the price argument.
Site Requirements: Power, Foundation and Transport
The HZS240 is the first model in this range where site preparation, rather than the plant itself, tends to decide the project timeline. Three items are worth settling before the order is placed.
Power supply. Installed power is around 400 kW. The transformer and incoming supply should be sized above the installed load with margin for simultaneous motor starting, and the supply voltage and frequency have to be confirmed against your local grid — plants are built to the voltage you specify, not adapted on site. On grids with frequent outages, a standby generator is sized to the installed load with additional margin for motor starting current, which is considerably higher than running current.
Foundation. A plant of this size imposes dynamic loads on the foundation that a small plant does not, and the civil work is a real line item rather than an afterthought. We supply the general arrangement drawing for your specific configuration — with anchor bolt positions, load data and the interface points — so that your civil engineer can design and pour the foundation while the plant is in production — the sequence is set out in foundation and installation preparation. Do not begin the foundation from a catalogue drawing of a different model: the bolt pattern and the load case differ between models.
Transport and handling. The mixer platform and the larger silo sections frequently exceed what can be shipped in standard containers, so HZS240 shipments often move as break-bulk or RORO rather than as a container set. That affects both cost and schedule, and it has a site-side consequence too: your receiving port and your site need lifting capacity for the heaviest single piece, not just for the average one. We confirm the exact shipping plan, weights and lifting points with the quotation, and we would rather do that early than discover it at the port. Shipping and logistics covers the break-bulk and RORO options in more detail.
Applications
The HZS240 is ideal for:
- Ready-mix concrete plants supplying commercial customers
- Commercial building and high-rise construction
- Precast and prestressed concrete production
- Government and municipal construction projects
- Large infrastructure projects (bridges, highways, dams, ports), major ready-mix operations, high-volume commercial production, precast factories, government projects.
