What "320 Blocks per Hour" Means When the Mixer Runs Dry
The press only produces when mix arrives on time and ground space is clear.
A mobile block making machine production line lives or dies by what happens before and after the mould drops. I watched a QMJ-class egg-layer on a site in Southeast Asia where the mixer batch took longer than the 25-second moulding cycle to discharge. The press sat idle half the shift. Workers stood around. The owner blamed the machine, but the bottleneck was a mixer sized for a slower press. [NEED_CITE: matching mixer batch discharge time to press cycle]
The Mixer-to-Press Handoff
A turnkey mobile block machine setup starts with raw material feeding and mixing. The QMJ2-45 cycles every 25 to 30 seconds, which means your mixer must discharge a full batch within that window or the press waits. We calculate the batch volume each mould format demands and match the mixer drum capacity and discharge rate to it, so the rhythm holds across all three hollow brick sizes.
Ground Space and Curing Logistics
Egg-laying machines drop blocks directly on the ground, which removes pallet cost but shifts the burden to curing area management. Every hour, 160 to 320 fresh blocks occupy floor space that must stay undisturbed for initial set. We help you map the walking path of the machine, the curing zone perimeter, and the water-spraying route so production never stops because the next row has nowhere to go.

Reading the Cycle and Output Table
The three output figures — 160, 240, and 320 pieces per hour — each assume a specific hollow brick dimension and cavity count per mould. The 25–30 second cycle is the press time alone; it does not include the operator walking the machine forward or the mixer refill pause. When you plan an eight-hour shift, factor in mould change time if you run more than one format that day. Diesel power removes grid dependency but adds fuel logistics to your daily checklist.
The Cost of Skipping Line Planning
Quoting a mobile press without its supporting stations leads to predictable gaps. The mixer is too small, so workers hand-feed batches and the cycle stretches. No curing layout means blocks get stepped on before they set. Labour is allocated only to the press, leaving nobody to manage the feed hopper or water the curing rows. The owner then assumes the machine underperforms, when in reality the line around it was never designed. [NEED_CITE: common line mismatches in small block plants]
Why Source the Supporting Line Here
Block machinery is our only product focus, so the mixer, feed hopper, and curing logistics are specified as one matched set rather than assembled from separate vendors. We configure the line against your actual mix design and local aggregate, not a catalogue default. Mould design covers the hollow brick formats your market sells, with drawings you can verify before production. Automation level is selectable — you can start with manual operation and add semi-automatic feeding later. Installation support includes operator training on your site.

Frequently Asked Questions
Q: How do I size the mixer so it keeps up with the QMJ2-45 across different block formats?
A: Each hollow brick format draws a different batch volume per cycle. We calculate the mix weight per mould, multiply by the number of moulds you plan to run per hour, and match the mixer drum capacity and discharge speed to that throughput. The goal is a batch landing in the feed hopper before the 25–30 second cycle ends.
Q: What ground area do I need for curing when blocks are laid without pallets?
A: Fresh blocks must sit undisturbed for initial set before you can walk or stack near them. We estimate your daily output in the chosen format, multiply by the block footprint, and add walking lanes for the machine and water-spraying access. This gives you the minimum curing zone to plan before the first shift.
Q: How should I allocate labour across the line when the press needs only one to three workers?
A: The press crew handles mould filling and machine movement, but someone must manage the mixer batch cycle, refill the feed hopper, and tend the curing rows with water. We map each task to the cycle timing so you know the total headcount before production starts.
Q: What supporting equipment usually gets left out of a mobile machine quotation?
A: Mixers, raw material feed hoppers, water supply for curing, and ground preparation tools are often excluded. We include these in the line layout from the start so you receive a complete station list rather than discovering gaps after the press arrives on site.
