Block Making Machine in Lebanon: Size It to Yard and One Shift
10 October 2026 · 6 min read
Quick answer
In Lebanon the price of a block machine follows the configuration the site can actually run: the automation level, the mould sets for each product, the pallet system and the power panel, plus freight and duty. A compact yard and one paid shift usually point to a smaller fully automatic press, not a large one that stands idle.
A block making machine in Lebanon has to fit two realities at once: a yard that is often only a few hundred square metres, and a workforce you can pay for one eight hour shift. That pair, not the output figure printed in a brochure, decides which press you buy. A QST8-15 running a 980 x 860 x 22 mm pallet weighs 14 t, carries 95 kN of vibration force and reaches 90,000 standard bricks in an eight hour shift, and it fits plots that a 1,350 x 880 x 25 mm pallet machine cannot serve. Bigger is not better when the stockyard cannot hold the green blocks or no second shift exists. This guide works through yard area, pallet size, cement consumption and mould changeover in the order that moves your cost.
1. Let yard area and one shift pick the model
Your yard is the first specification, and it can be measured. A machine that completes a pallet cycle every 18 seconds still needs somewhere to put the fresh blocks while they cure, and that place has to hold a week of output under cover and roughly three weeks of stock before the blocks are saleable. Take the daily output you really need, multiply it by the curing period, and you get the pallet count your pad must carry. If the number does not fit, the honest answer is a smaller machine working a longer day rather than a larger machine standing idle.
A single 8 hour shift is about 250 working days a year, so a modest press used every day usually beats a large press used four hours a day. Walk your site and measure the pad in metres before you open any quotation: curing aisle, stacker travel and the turning circle for a delivery truck all have to fit inside the same boundary. Sizing the machine to the yard is the cheapest decision in the whole project, and it is the one buyers skip.
2. Pallet size separates the QST8-15 from the QST1200
Pallet footprint is what you feel in the stockyard. The QST8-15 runs a 980 x 860 x 22 mm pallet, weighs 14 t, delivers 95 kN of vibration force and tops out near 90,000 standard bricks per 8 hour shift, on a 15 to 23 second cycle. The QST1200 runs a 1,350 x 880 x 25 mm pallet, weighs 17 t, delivers 150 kN and reaches 120,960 standard bricks per 8 hour shift, on a 15 to 25 second cycle, with a vibration frequency of 3,800 to 4,500 per minute. The larger pallet buys more pieces per cycle and stronger compaction for load bearing block.
It also demands a wider curing aisle, a longer stacker and more room for the forklift. On a compact plot the smaller pallet is not a downgrade, it is the version that keeps the yard running every day. Choose the QST1200 only when you can already show the curing area and the stacking space to feed 120,960 bricks a shift, and choose the QST8-15 when the site is the limit.
3. Crushed limestone and costly cement: cut cement per block
When the aggregate is crushed limestone and the cement arrives as an imported bag, cement is the only line in the mix you cannot substitute, and it sets your cost per block. Semi-dry concrete formed by vibration plus press is how you pull that cost down: mix to a low water to cement ratio near 0.42 to 0.50, press at the rated 31.5 MPa, and demould straight onto the pallet instead of pouring a wet mix. Crushed stone up to 60 mm feeds the twin shaft mixers used on these lines, so you can buy local stone and spend money on cement only where the strength test demands it.
A low water to cement ratio means less cement per cubic metre, less water to evaporate and faster early strength, so pallets turn over sooner and you need fewer of them. The common error is adding water to make the mix easier to place; that raises the cement bill without raising strength, and it shows up as edge damage on the pallet. Keep the mix stiff and let the 95 kN or 150 kN of vibration force do the compacting work.
4. Changeover: 200 mm load bearing block and kerb stone on one machine
A yard quoting both a 200 mm load bearing hollow block and a kerb stone does not need two machines; it needs one press and the right number of mould sets. The block mould sets the pallet charge and the vibration time, the kerb profile sets the fill depth and the demould speed, and the machine has to be reset between them. Plan that change as a scheduled stop, keep the setting gauges on site, and treat the first ten pieces after every change as a test batch rather than saleable stock.
Budget the mould count before you budget the machine: one set for the 200 mm structural block, one for the kerb profile, one for a standard 240 x 115 x 53 mm brick, and a spare wear set. Mould steel, not the press frame, decides whether the corners stay square after a long production run, so ask what the mould is made of before you ask what the machine costs.
5. Crew and power on a single shift
A line with automatic pallet return and automatic stacking runs on 3 to 4 operators per shift, against 8 to 10 on a manual layout making the same output, and on one shift that gap is your whole payroll. Total installed power on this class of line commonly lands between 60 and 90 kW once the mixer, the conveyors and the pallet system are added to a forming machine rated around 37.4 kW. Ask your own electrician what the supply can carry, then tell us your voltage and frequency so the panel is built for your site rather than converted on arrival.
Water and covered curing space count as hard as electricity. A press that makes 90,000 bricks in a shift still needs those bricks kept damp for 7 days and stacked for about 21 days before they are sold, and the yard has to hold them in that time. Confirm the water source and the storage bay at the same stage you confirm the power.
6. What we confirm before quoting a block making machine in Lebanon
We do not fix a configuration until the site answers are in writing. The list below is the one we use, and it applies whether the yard sits in Beirut or inland.
- Yard area and pad layout: curing space in square metres, the truck turning circle and the covered area you can dedicate.
- Block list: every size you sell, from the 390 x 190 x 190 mm hollow block to the 240 x 115 x 53 mm brick and the kerb profile, with the strength each one is tested to.
- Aggregate and cement: the crushed limestone grading you can actually buy, its largest stone size, and the cement type delivered to the yard.
- Power: the load in kW, the phase and the frequency, confirmed with your electrician against the main drives and the mixer motor.
- Unloading: crane or forklift capacity at the port and at the yard, and the tightest gate on the route to the foundation pad.
Frequently asked questions
How much does a block making machine in Lebanon cost?
There is no single figure, because the same press is quoted as a manual layout or a fully automatic one and the gap between those versions is wide. Decide how many operators you can pay per shift, then price that configuration. Compare two suppliers only when the automation level, the mould set and the pallet system are identical.
Which block making machine suits a small yard in Lebanon?
For a plot that holds one curing aisle and one shift, the QST8-15 is the practical choice. It runs a 980 x 860 x 22 mm pallet, weighs 14 t, delivers 95 kN and reaches 90,000 standard bricks per 8 hour shift. Step up to the QST1200 only when you can store and cure 120,960 bricks a shift.
Why does pallet size matter more than the machine price?
Because the pallet decides how much yard you need. A 1,350 x 880 mm pallet machine needs a wider curing aisle and more stacking space than a 980 x 860 mm one, and if that space does not exist the extra output is never produced. You pay for the space once, in land and handling.
How can I cut cement consumption in a block yard?
Form semi-dry concrete with vibration plus press instead of a wet mix, and hold the water to cement ratio near 0.42 to 0.50. Pressing at 31.5 MPa with 95 kN or 150 kN of vibration force reaches the tested strength with less cement per cubic metre. Never add water to improve workability, because it raises the cement bill and lowers strength.
Can one machine make 200 mm hollow blocks and kerb stones?
Yes, if you buy the mould sets with the press. The machine charges a different mould for each product and is reset between runs, so schedule the change as a real stop and check the first ten pieces after it. Buy one set for the 200 mm block, one for the kerb profile and a spare wear set.
How many operators and how much power does an automatic line need?
An automatic line with pallet return and stacking needs 3 to 4 operators per shift, against 8 to 10 for a manual layout on the same output. Total installed power commonly falls between 60 and 90 kW. Confirm the load, phase and frequency with your own electrician before ordering the panel.
