Concrete Block Making Machinery & Complete Production Lines
Next Engineering Solutions Ltd supplies fully automatic QILU concrete block making machines — QT5-15, QT7-15, QT10-15 and QT12-15 — with complete production lines for hollow blocks, solid blocks, pavers, interlocking bricks, kerb stones and fly ash bricks.
Complete concrete block plants, sourced and supported by NES
Next Engineering Solutions Ltd (NES) specializes in sourcing, supplying and installing high-quality concrete block manufacturing plants from leading manufacturers in North China. We deliver complete, high-performance solutions tailored for modern construction material production.
Every QILU machine we supply is engineered with intelligent PLC control, hydraulic pressing and robust vibration technology to produce hollow blocks, solid blocks, pavers, curbstones and interlocking bricks with consistent density and strength.
Beyond the machine itself, NES designs the full plant — cement silo, batching, mixing, conveying, forming, stacking and curing — then installs, commissions, trains your operators and supports the plant for its whole working life.
Choose the right block machine for your production target
Four fully automatic models cover every scale of production — from compact multi-product factories to large commercial block plants. The capacity scale on each card shows where the model sits in the range for standard 400 × 200 × 200 mm hollow blocks.
QT5-15
A flexible entry into automatic block production — low labour requirement, quick mould changing and stable output for multi-product factories making blocks and pavers on one line.
QT7-15
Higher daily output with 95 kN vibration force and touch-screen PLC control — proven in the NES-supported Bholaganj project for reliable commercial hollow block, paver and solid brick production.
QT10-15
Fast 10–15 second cycles with international-brand PLC, hydraulic and sensor components (Siemens, Omron, Rexroth class) for high-volume block, paver and fly ash brick manufacturing.
QT12-15
The largest moulding area in the range — 1300 × 850 mm — for professional concrete product factories, real-estate developers and infrastructure projects that need maximum daily output.

One production line, many concrete products
Every QT machine supports quick mould replacement, so a single line can serve construction, road, landscaping and infrastructure markets.
Hollow Concrete Blocks
For walls, boundary walls, partitions and general building construction.
Solid Blocks & Bricks
For load-bearing work, foundations, masonry and heavy-duty construction.
Pavers & Interlocking
Zigzag, I-shape, Holland and rectangular pavers for roads, footpaths and yards.
Kerbs, Grass & Special Blocks
Kerb stones, grass planting blocks, permeable and slope protection products.
From raw material to finished block — one integrated system
NES configures the complete line around your chosen machine: cement silo, batching, mixing, conveying, forming, stacking and curing, all coordinated under one PLC system.
Silo & Batching
Cement silo, screw conveyor and aggregate batching measure every material accurately.
Mixing
JS-series twin-shaft mixer prepares a uniform dry concrete mix with water and additives.
Feeding & Forming
Material is fed to the mould and formed by vibration with hydraulic compaction.
Pallet & Stacking
Automatic pallet feeder and stacker handle fresh blocks with minimal labour.
Curing
Natural, rack or chamber curing brings blocks to full strength.
Storage & Dispatch
Cured products are cubed, checked, stored and delivered to market.

Choosing your concrete block machine
Which QT model is right for my project?
It depends on your daily production target, product mix and budget. As a guide: the QT5-15 suits small-to-medium factories, the QT7-15 suits commercial and project-based production, the QT10-15 suits large-scale plants, and the QT12-15 suits industrial-scale and infrastructure supply. Share your target output and NES will recommend the right configuration.
Can one machine produce both hollow blocks and pavers?
Yes. All QT models support quick mould replacement, so the same machine can produce hollow blocks, solid bricks, pavers, interlocking blocks, kerb stones, grass blocks and customized products.
What is included in a complete production line?
A complete line typically includes the block machine, cement silo, screw conveyor, aggregate batching machine, twin-shaft mixer, belt conveyors, automatic pallet feeder, hydraulic station, PLC control cabinet, stacker and curing arrangement.
What raw materials can be used?
Cement, sand, stone chips, stone dust, quarry dust, fly ash, slag, crushed stone and gravel, with optional pigment and additives. NES helps develop the right mix design for your local materials.
Does NES provide installation and training?
Yes. NES provides factory layout design, installation and commissioning, operator training, spare parts support and long-term after-sales service for local and international projects — proven in our Bholaganj project in Bangladesh.
