Which Block Machine Suits the Syrian Market? Capacity, Power and Moulds

Which block machine suits the Syrian market comes down to three inputs, not to a catalogue ranking: the products you will sell, the power and space your site has, and the shift output you can place with buyers. Each input deletes machine classes. A plant casting a 390 × 190 × 190 mm hollow block and a 240 × 115 × 51 mm solid brick on one frame needs a different mould count from a plant that also sells a 200 × 100 × 60 mm paver, and a site that cannot carry 104 kW cannot run the largest frame.

What does the product mix decide before anything else?

Product type sets the mould, and the mould sets the cavities in one stroke. On a QS800 hydraulic press a 390 × 190 × 190 mm hollow block runs 5 pieces per mould, a QS1000 runs 10 pieces and a QS1500 runs 12; the same three frames carry 28, 45 and 87 pieces of a 240 × 115 × 51 mm standard brick. Cavities multiply the cycle, so one stroke on the large frame returns more than double the small frame.

Mould changeover is the other half of the decision. A yard selling hollow block, solid brick and paver off one machine pulls the mould several times a week, and each change costs part of a shift. Where the mix is that wide, one frame covers the range: a QST6-15 returns 6 hollow blocks, 32 to 36 standard bricks or 21 to 24 coloured floor tiles of 200 × 100 × 60 mm per mould, so the moulds you order with the machine matter more than the headline capacity.

• 390 × 190 × 190 mm hollow block: 5 pieces per mould on a QS800, 10 on a QS1000, 12 on a QS1500.
• 240 × 115 × 51 mm standard brick: 28, 45 and 87 pieces per mould on the same three presses.
• 200 × 100 × 60 mm paver: 24, 32 and 40 pieces per mould on the QS press series.
• 170 × 80 × 80 mm small block: 30 pieces per mould on a QS800 and 36 on a QS1000.

Does the site power supply set the machine class?

Installed capacity is the sum of the drives that run together: the hydraulic pump, the vibration motors, and the fan and conveyor motors behind them. Across the QST range that sum steps from 34.4 kW on a QST6-15 and 44.9 kW on a QST8-15 to 57.6 kW on a QST1200, 69.1 kW on a QST1500 and 104 kW on a QST1800. The hydraulic presses sit in the same band, at 70 kW on a QS800, 105.4 kW on a QS1000 and 108.2 kW on a QS1500.

A 104 kW frame forces a supply that carries the starting current of the largest motor, not only the running load, and everything downstream is sized from that: transformer or generator, cable cross section, and the panel feeding the mixer and the cuber. Where the supply is short, fix the moulding class first and add handling later, because a cuber can be retrofitted onto a running line. Tell us the supply you can hold at the panel and we size the electrical package around it.

How does the capacity target pick the tier?

Output is arithmetic: cavities per mould multiplied by strokes per shift. An 8-hour shift holds 28,800 seconds, so a cycle between 15 and 23 seconds gives 1,250 to 1,920 strokes, and the cavities of your product set the ceiling of that tier. The published figures sit on the same arithmetic: up to 220,000 standard bricks per 8-hour shift on a QST1800, up to 120,960 on a QST1200, up to 90,000 on a QST8-15, and up to 135,000 pieces of 240 × 115 × 50 mm brick on a QSMT1000.

Use those figures to pick the smallest class that beats your target, then test it against the shifts you can staff. A QST1200 at 57.6 kW on a 1,350 × 880 × 25 mm pallet is the usual answer for a plant that must reach six figures of standard brick per shift; a QST1800 at 34 t and a 1,400 × 1,400 × 30 mm pallet earns its weight only when one shift carries the whole target.

Where does the nameplate figure stop and effective output start?

A nameplate figure assumes the moulding cycle never waits. On a pallet-based line it waits at the curing rack: every pallet leaving with green blocks has to come back before the next one is filled, so the pallet fleet and the rack capacity set a ceiling no cycle time can beat. A QS-1200A cuber handles about 3,800 pallets per shift, and a QS-1000G-C matches that at 12 to 15 seconds per layer.

Mould changes, mix changes and the closing hour of a shift take the rest, so plan from the pallets you can push through curing, the moulds you own and the hours the crew works, and treat the plate figure as an upper limit. Give us your target as product weight per shift or as wall area to be built, and we convert it into blocks per shift.

Pallet fleet and yard area come with the class

The pallet board is the largest consumable on a pallet-based route, and the fleet has to cover the whole curing cycle, not the machine alone. A plant running a 1,400 × 1,400 × 30 mm board needs storage and a yard laid out for that size, and the yard grows with the pallet count rather than with blocks sold. Where the site is tight, the pallet-free route drops the boards: the QSMT1000 moulds on a 1,150 × 1,100 mm area and stacks the wet product to a 1,100 mm height.

• QST1800: pallet 1,400 × 1,400 × 30 mm, machine 15,500 × 5,500 × 3,200 mm, weight 34 t.
• QST1500: pallet 1,350 × 1,150 × 30 mm, machine 11,500 × 4,550 × 2,800 mm, weight 20 t, installed capacity 69.1 kW.
• QST1200: pallet 1,350 × 880 × 25 mm, machine 11,500 × 4,550 × 2,800 mm, weight 17 t.
• QS-1200A cuber: floor area 12,000 × 3,000 mm, weight about 18,000 kg, total power 34.15 kW.
• QS-1000G-A cuber: 7,500 × 7,000 × 5,500 mm, weight about 6,200 kg, power 15 kW, about 1,700 pallets per shift.

Which three inputs do you send us?

Three items narrow the range to one configuration: the product mix with its sizes and the share each product carries, the supply you can hold at the panel plus the covered area and the open yard, and the output you need per shift with the shifts you can staff. Add the pallet size you intend to run and the block strength your buyers test.

With those three we return a configuration list: the moulding frame, the moulds for your product mix, the pallet size and fleet count, the handling and cuber package sized to the same output, and the power, weight and foundation figures needed to prepare the site. If the answer is a two-stage build we mark what can be added later, because a line running at 57.6 kW now and ready for a 104 kW frame later beats the wrong frame bought today.
