QT4-40 Brick Making Machine

The QT4-40 is a best-selling semi-automatic block/brick making machine designed for small-to-medium production lines. It uses a full automatic spiral material laying system, combines pressure with strong vibration, and produces hollow blocks, solid bricks, pavers, curbs and slabs with quality comparable to larger hydraulic machines.

It is a semi-automatic machine. While material laying into the mould is done by a fully automatic spiral system, certain tasks (feeding aggregates, forklift/pallet handling and demoulding) are manual or semi-manual depending on your line setup.

Host dimensions 1350×1460×1800 mm; total machine power 8.8 kW; mould cycle (period) 40 s; vibration force 30 kN; pallet size 850×450×20 mm; mixer model JQ350; host weight ≈1060 kg; available voltages 220/380/415/440 V. It uses a Mode 350 speed reducer for mould lifting/lowering.

Cycle time is 40 s (≈90 cycles/hour). Example outputs: 400×200×200 mm — 4 pcs/cycle → 360 pcs/hour → 2,880 pcs/8-hr shift; 400×250×200 mm — 3 pcs/cycle → 270/hr → 2,160/shift; 400×150×200 mm — 5 pcs/cycle → 450/hr → 3,200/shift; 400×100×200 mm — 7 pcs/cycle → 630/hr → 5,040/shift. For smaller pavers: 230×110×70 mm — 18 pcs/cycle → 1,620/hr → 12,960/shift. (Actual output depends on operator efficiency and curing/storage workflow.)

The machine can produce hollow blocks, solid bricks, various pavers (S-shape, interlocking), curbstones and slabs. It supports common mould sizes such as 400×200×200, 400×250×200, 400×150×200, 400×100×200, 230×110×70 (solid), and custom moulds can be fitted as required.

Two typical mix options given: 1) 8–10% cement, 30–40% sand, 50–60% crushed stone; 2) 8–10% cement, 30% fly ash, 60% sand or stone powder. Other aggregates, additives or local recipes can be used provided they achieve required workability and strength.

A typical semi-automatic setup usually requires 2–3 operators per machine (one for material feeding/mixer, one for machine operation/demoulding, one for pallet handling/stacking). Staffing depends on automation level of the rest of the line and desired throughput.

Block size is changed by swapping the mould and pallet. The QT4-40 uses a Mode 350 speed reducer to lift/lower the mould; moulds and pallets are standard interchangeable components. Ensure correct pallet/mould alignment and check the speed reducer and fastenings after each change.

Total installed power is 8.8 kW. Available voltage options include 220 V, 380 V, 415 V and 440 V — choose the option that matches your site. Energy consumption approximates the rated power while operating; actual consumption depends on working cycles and auxiliary equipment (mixer, curing ovens, conveyors).

Regular maintenance includes: check and lubricate speed reducer and moving parts; inspect and tighten fasteners; check vibrators and electrical connections; maintain the mixer and clean moulds/pallets after production; replace worn mould liners and pallet boards as needed. Follow a daily/weekly/monthly checklist and keep spare wear parts on hand for minimal downtime.

Yes — spare parts for common wear items (pallets, moulds, vibrators, belts, bearings, electrical components) are typically available. Many suppliers provide technical support, installation assistance and spare parts packages. Confirm specific parts availability and lead times with the supplier before purchase.

Packaging and delivery depend on supplier and order quantity. Machines are usually export packed and shipped by container or on a pallet. Lead time varies by stock and order size — contact the supplier for current lead time estimates for single units or full production lines.

Key advantages: lower power consumption, simpler operation, full automatic spiral material laying for even distribution, combined pressure and strong vibration for high-strength blocks, and comparable final product quality. It is particularly efficient for hollow block production with lower operating costs.

Use: cycles/hour = 3,600 ÷ mould period. With a 40 s mould period, cycles/hour ≈ 90. Then output/hour = cycles/hour × pcs per cycle (depends on mould). Example: 4 pcs/cycle → 90×4 = 360 pcs/hour. Multiply by shifts or days for longer-term planning.

Warranty terms and after-sales services vary by supplier. Typical offerings include a manufacturer warranty period, availability of spare parts, remote or on-site technical support and installation/training packages. Confirm exact warranty length and service terms with the seller at time of purchase.
