Mobile Block Making Machine QMR4-45 | Full Range

Single Focus Design — the QMR4-45 mobile block machine is specified as one matched system with mould and pallet requirements eliminated, so capacity figures align with what you actually produce on-site.

Why "3000 Pieces Per Day" Means Nothing Without the Block Format

Every output figure for this mobile block machine for sale is tied to a specific hollow block dimension and mould cavity count.

Buyers regularly receive quotations stating a single daily capacity number with no mention of which block size was used to calculate it. I have seen contractors order a machine expecting 4500 blocks daily, only to discover that figure assumed the smallest format while their market actually demands the largest — cutting real output to two-thirds of what they planned for. The QMR4-45 capacity is therefore stated per format: 3000 pieces per day for 400×200×200mm blocks at four cavities per mould, rising to 4500 pieces per day only when running 400×120×200mm blocks at six cavities, both based on an 8-hour shift [NEED_CITE: block machine capacity calculation standards by format].

Eliminating the Pallet and the Concrete Floor

The egg-laying design of this mobile block machine for sale means it deposits wet blocks directly onto the ground as it moves forward. There is no pallet circulation system, no pallet return conveyor, and no need to invest in thousands of wooden or bamboo pallets that warp, break, and consume storage space. For a contractor who already has a flat, hard-packed area on a building site, the machine begins producing blocks the same day it is unloaded.

Dual Power for Unreliable Grids

Remote construction sites in many regions face load-shedding or simply have no three-phase supply available. The QMR4-45 addresses this with a selectable power source: a 6kW electric motor where grid power is stable, or a 6-8HP diesel engine where it is not. This choice is made before production so the machine arrives configured for your actual site conditions rather than requiring a field retrofit [NEED_CITE: diesel engine adaptation for construction machinery in off-grid locations].

Reading the Specs That Actually Matter on Site

The 40-45 second moulding cycle governs your realistic throughput more than any other number on the sheet. Combined with the manual mould change procedure, it tells you how many format switches you can afford in a single shift before production time erodes. The 810kg net weight keeps the machine portable — a small crane or forklift can reposition it between buildings on a large project — while still providing enough mass for the vibration system to consolidate the concrete mix properly. The 6kW rated power requirement means the electric version can typically run on a standard industrial supply without a dedicated transformer, but frequency must be confirmed for your country before the motor is wound.

The Cost of Skipping Site Condition Checks

Ordering a mobile block machine for sale without verifying your aggregate gradation and cement availability against the machine’s mix requirements leads to blocks that crumble at demoulding or fail compression tests weeks later. I recall a Middle East project where the local sand carried a high clay content; the machine ran fine, but block strength was inconsistent until the mix was adjusted — a problem that delayed commissioning by two weeks. Voltage and frequency mismatches are equally costly: a motor wound for 380V/50Hz will overheat and burn out on a 440V/60Hz supply, and replacement is not a quick fix in a remote location [NEED_CITE: motor failure caused by voltage and frequency mismatch in export machinery].

Why Source This Machine Here

Block machinery is our single focus, which means the QMR4-45 is not assembled from unrelated components sourced from different factories — the press, mould, and vibration system are matched as one unit. We configure the machine against your actual local aggregate and target block format rather than shipping a catalogue default. Custom mould design is available to buyer drawings, so if your market requires a hollow block dimension outside the standard 400×200, 400×150, or 400×120 series, the mould can be engineered to your specification. Automation level is selectable: you can start with the semi-automatic QMR4-45 and move to a higher-tier automatic line later as your market grows. Installation, commissioning, and operator training are included so your team is producing acceptable blocks before our technician leaves the site.

What to Share Before Requesting a Quote

To size this mobile block machine for sale accurately, tell us which hollow block dimensions your market sells, your target daily output per format, and whether your site has reliable grid electricity or requires the diesel option. Share your local aggregate type and any existing mixing equipment so we can confirm compatibility.

Frequently Asked Questions

Q: How is daily output calculated, and which block format does each figure assume?
A: Every output number is tied to a specific hollow block size and mould cavity count. The QMR4-45 produces 3000 pieces per day with 400×200×200mm blocks at four cavities per mould, 3500 pieces with 400×150×200mm at five cavities, and 4500 pieces with 400×120×200mm at six cavities, all based on a continuous 8-hour shift at the 40-45 second cycle time.

Q: Can I run this machine on diesel only if my site has no reliable grid power?
A: Yes. The QMR4-45 is available with a 6-8HP diesel engine as the primary power source. This option is selected before production so the machine arrives fully configured for off-grid operation. You only need to arrange diesel fuel supply at the site.

Q: Do I need a concrete floor or any pallets to operate this egg-laying machine?
A: No pallets are required. The egg-laying design deposits blocks directly onto the ground as the machine moves forward. You need a flat, hard-packed surface — a compacted soil area or existing concrete slab both work — but no dedicated concrete factory floor is necessary.

Q: What voltage and frequency options are available, and is the control display in my language?
A: The QMR4-45 electric version supports 220V or 380V, with custom voltage available on request. Frequency and control display language must be confirmed before production to avoid commissioning delays. We document the agreed electrical specification and language before manufacturing begins.

Q: What is included in the shipment — just the press, or also a mixer and feeding equipment?
A: The standard quotation covers the QMR4-45 press and its mould. Raw material mixing and feeding equipment can be added to match your site setup. Clarify at the inquiry stage whether you need a complete line or only the mobile press unit.
