What the "320 Pieces per Hour" Figure Does Not Tell You About a mobile block making machine production line
Capacity only becomes real when the upstream mixer and downstream curing area can sustain the same beat.
Buyers often see a single hourly figure in a quotation and assume it applies to every block format on the machine. In practice, the 320 pcs/h number on the QMJ2-45 assumes the 400×100×200 mm hollow mould with four cavities per cycle; switch to the two-cavity 400×200×200 mm mould and the same cycle delivers 160 pcs/h. I have watched a mobile block making machine production line in West Africa lose an entire shift’s worth of output because the pan mixer could not feed fast enough to match the press cycle, leaving the operator standing idle between batches.

Matching Mixer, Press and Curing Area as One Timed Loop
The QMJ2-45 completes a moulding cycle in 25-30 seconds, which means the supporting mixer must deliver a fresh batch to the operator within that window or the press sits idle. A pan mixer sized too small forces the operator to wait, while one sized too large dumps material that begins to stiffen before the press can use it. Treating the mobile block making machine production line as three stations on a single stopwatch is what separates a realistic daily count from a theoretical one.
How Egg-laying Removes Three Stations from the Line Layout
Because the QMJ2-45 lays blocks directly onto the curing floor, the layout eliminates the pallet return conveyor, the pallet feeder, and the curing-rack handling system that a static press requires. This reduction shortens the line to a raw material feed hopper, a mixer, and the mobile press itself — a configuration that fits inside a single standard workshop bay. The trade-off is that the curing area must be flat, swept clean between passes, and large enough to hold an entire shift’s output without the operator driving the machine over green blocks.

Reading the Specs That Actually Shape Your Daily Output
The moulding cycle of 25-30 seconds is governed by the time needed for the operator to position the machine, drop the mix, and engage the hydraulic static pressure. Mould cavity count directly scales output: the four-cavity 400×100×200 mm mould produces double the hourly count of the two-cavity 400×200×200 mm mould, so a buyer whose market primarily uses the larger hollow block must plan for a lower daily volume even though the machine itself is unchanged. Labour requirement of one to three workers covers one person operating the press, one feeding the mixer, and one smoothing or marking freshly laid blocks. Voltage and frequency must be confirmed before winding starts at the factory; an incorrect motor winding discovered on site delays commissioning by weeks.
The Cost of Treating the Press as a Standalone Purchase
When the mixer is undersized, the QMJ2-45 spends a large portion of each hour waiting, and the quoted hourly capacity quietly collapses. When the curing floor is not level, the egg-laying shoes skid, producing tilted blocks that must be scrapped. When voltage is assumed rather than confirmed, the motor overheats within the first week, and the buyer is left sourcing a replacement winding locally. [NEED_CITE: consequences of voltage mismatch in exported electric motors] Each of these failures is avoidable with a line-level specification rather than a press-only quotation.
Why the Supporting Equipment Conversation Happens Here
Block machinery is our single focus, so the QMJ2-45 is never quoted in isolation. We specify the mixer capacity, feed hopper volume, and curing area dimensions as a matched set. Every configuration is checked against the buyer’s local aggregate and target block format, not a default catalogue entry. Moulds for the three hollow block sizes are designed and supplied together with the machine, and custom drawings are accepted when the local market demands a non-standard format. The automation level is selectable, so a buyer who starts with manual operation can add feeder automation later without replacing the press.

- Mould drawing and format list covering all three hollow block sizes
- Hydraulic and electrical schematic for on-site integration
- Factory test record run on the buyer’s specified block format before dispatch
Installation, Commissioning & Support

- Electric motor supply confirmed to site voltage and frequency before motor winding is finalized
- Machine ships partially dismantled; reassembly covers frame, mould head and electric panel
- First-day commissioning includes cycle timing against the connected mixer to verify line beat

What We Need From You to Size the Line
Tell us which hollow block format your market sells most, the daily volume you need to hit, and the raw materials you can source locally. Share your site voltage, frequency, and the dimensions of the curing area you have available. If you already own a mixer or conveyor, give us the make and capacity so we can check whether the beat aligns.
Frequently Asked Questions
Q: How is daily output calculated and which block format does each capacity figure assume?
A: Each output figure on this page is tied to a specific mould cavity count and a 25-30 second cycle. The 320 pcs/h number assumes the 400×100×200 mm hollow mould with four cavities; the 160 pcs/h number assumes the 400×200×200 mm mould with two cavities. Daily shift figures multiply hourly output by eight working hours.
Q: What supporting equipment is needed to keep the QMJ2-45 running at stated cycle times?
A: A pan or drum mixer that can deliver a fresh batch every 25-30 seconds, a raw material feed hopper sized to hold at least one mixer batch, and a level curing floor large enough to store a full shift of laid blocks without the machine crossing green product.
Q: How does the egg-laying design change the curing and handling layout compared to a pallet-based line?
A: Egg-laying removes the pallet return conveyor, pallet feeder, and curing rack stations. Blocks are laid directly on the floor, so the curing area must be swept and flat. This shortens the line but requires more open floor space for curing.
Q: What voltage and frequency options are available, and is the control display language confirmed before shipment?
A: Voltage and frequency are confirmed during the quotation stage so the motor winding matches the buyer’s site supply. Control language on any electrical panel is agreed before dispatch to avoid on-site commissioning delays.
Q: How do mould change and format switching work on-site, and what is the realistic turnaround time?
A: Moulds are interchangeable and changed manually by loosening the mounting bolts, lifting the current mould, and setting the new one in place. A practiced two-person team can complete the swap within a short break, keeping format switching inside a single shift.
