QT7-15 Fully Automatic Concrete Block Production Line
A high-capacity, fully automatic line for hollow blocks, pavers, solid bricks and interlocking products — engineered, supplied, installed and supported end-to-end by Next Engineering Solutions Ltd.
Advanced high-capacity block manufacturing
Next Engineering Solutions Ltd presents the powerful QILU QT7-15 — a fully automatic production line built for large-scale, high-efficiency concrete block manufacturing. It combines advanced hydraulic vibration, intelligent PLC automation and heavy-duty industrial construction to deliver premium hollow blocks, solid bricks, pavers and interlocking products at consistent quality.
The QT7-15 is engineered for manufacturers who need higher capacity, stable round-the-clock performance, lower labour dependency and long-term reliability. Automatic feeding, hydraulic pressing and high-frequency vibration work together to produce excellent block density, dimensional accuracy and compressive strength for modern construction.
Commercial factories & project-based production
An ideal fit for entrepreneurs, concrete product factories, building-material suppliers, real-estate developers and infrastructure contractors who need reliable daily output with flexible mould options.
- Medium-to-large daily production targets
- Multi-product factories (blocks + pavers)
- Government & infrastructure supply
- Export-grade, consistent block quality
Why choose the QT7-15
The QT7-15 sits in the high-output tier of the QT series — a step up from entry models, with the capacity and automation to anchor a serious commercial plant.
Higher Throughput
A larger forming table and 95 KN vibration produce more blocks per cycle than entry-level QT5-class machines, lifting daily output significantly.
True Automation
PLC-driven batching, feeding, molding and stacking reduce manual handling and labour cost while improving repeatability.
One Machine, Many Products
Quick mould changeover lets a single line cover hollow blocks, pavers, solid bricks and interlocking products as demand shifts.

The automatic production process
From raw material to finished, cured product — five coordinated stages running under one PLC system.
Batching
Sand, stone dust, cement and additives are proportioned accurately.
Mixing
The JS750 twin-shaft mixer prepares a uniform concrete mix.
Feeding & Molding
Material is fed to the mould with vibration and hydraulic compaction.
Stacking
Fresh blocks are transferred and stacked ready for curing.
Curing & Dispatch
Products are cured, quality-checked and prepared for delivery.
Production capacity
Actual output depends on mould design, raw material quality, product size, curing arrangement and operating conditions.

Common questions about the QT7-15
Can the QT7-15 produce both hollow blocks and pavers?
Yes. By changing moulds, the machine can produce hollow blocks, solid bricks, pavers, interlocking blocks, kerbstones and other concrete products on the same line.
Is the production line fully automatic?
Yes. The QT7-15 is designed as a fully automatic system covering batching, mixing, feeding, molding, conveying and stacking — with options depending on the configuration you select.
What affects the final daily production?
Daily output depends on mould design, cycle time, block size, raw material quality, operator skill, curing area and working hours per day.
Does NES handle installation and training?
Yes. Our engineering team provides factory layout planning, installation and commissioning, operator training and ongoing after-sales and spare-parts support for both local and international projects.
