QT6-15 Fully Automatic Cement Brick Machine – Product Overview

1. General Description

The QT6-15 fully automatic cement brick machine is a fully automated, non‑fired brick production system designed specifically for small and medium‑sized building material plants. The entire machine is welded from thickened Q235 steel plate in one piece, using CO₂ shielded welding and stress‑relief ageing treatment. Its overall dimensions are 7450×2450×2900 mm, and it weighs 12.5 tons. The robust frame ensures high rigidity, so the machine does not deform or shake even under long‑term high‑pressure continuous operation.

The equipment is equipped with a PLC‑based intelligent fully automatic control system. All core electrical components are selected from world‑leading brands: the main motor is from Siemens or ABB, the control host uses an original Mitsubishi PLC (Japan), and the dedicated brick‑making control software is developed in‑house. Switching elements come from Schneider Electric (France) and Omron (Japan). The control system integrates four core functions: complete logic control, production program storage, automatic fault diagnosis, and remote monitoring. The 7‑inch touchscreen human‑machine interface is simple and intuitive. No specialised technician is required – ordinary workers can operate the entire machine independently after brief training. Only one operator is needed for daily production, significantly reducing labour costs.

2. Technical Highlights

The machine adopts a 16 MPa rated high‑pressure hydraulic forming combined with a 2800–5100 r/min wide‑frequency adjustable mould‑table integral vibration process. The vibration exciting force reaches 65 kN. After material distribution, the system expels air from the concrete within just 2–3 seconds, greatly improving the compactness of the green bricks. Once demoulded, the bricks can be directly stacked and transferred without the need for air‑drying or curing on pallets, saving substantial pallet purchase costs and curing yard space.

The integrated compact hydraulic station uses imported sealing components, offering high temperature resistance, leak resistance, and stable pressure holding. Together with the variable‑frequency vibration system, this machine increases overall output by 15%, reduces total power consumption by 10%, and improves the final brick strength by 30% compared to traditional old‑style brick machines.

The moulds are professionally carburised and heat‑treated to a hardness of 54–58 HRC, making them wear‑resistant and durable. A single set of moulds can reliably produce over 100,000 cycles. By changing moulds, the machine can switch to producing multiple brick types, truly achieving multi‑function versatility.

3. Raw Materials and Product Range

The QT6‑15 is compatible with a wide range of raw materials, including crushed stone, river sand, cement, stone powder, fly ash, coal cinder, slag, coal gangue, gravel, perlite, and recycled aggregates from construction waste – all without sintering, and with no exhaust gas or dust emissions, complying with environmental regulations worldwide. The raw materials are easily sourced and inexpensive, and solid waste utilisation further increases profit margins.

The machine produces a full spectrum of building materials for construction, municipal, landscaping, and water conservancy projects:

●Standard solid bricks: 240×115×53 mm

●Large hollow blocks: 390×190×190 mm and multi‑hole wall bricks

●Coloured permeable bricks: 200×100×60 mm

●Paving bricks: 200×160×60 mm and interlocking road bricks

●Specialty shapes: kerbstones, curbs, grass‑planting bricks, slope protection bricks, landscape flat bricks, etc.

With an optional secondary colour‑facing device, it can also produce through‑body paving bricks with a decorative coloured surface layer.

4. Production Capacity

The machine has a moulding cycle of just 15 seconds per mould. Under standard conditions:

●Solid standard bricks: 32 pieces per mould → 6,500–7,800 pieces/hour

●Hollow blocks: 6 pieces per mould → 864–1,080 pieces/hour

This stable output meets the bulk supply demands of small‑to‑medium brick plants.

5. Optional Auxiliary Equipment (Full Production Line)

The QT6‑15 can be combined with a complete set of automated auxiliary equipment to form a closed‑loop production line:

●Cement silo (50–100 t capacity) – available in split type (for container shipping) or integral type (lower cost, faster installation).

●Screw conveyor – automatically transports bulk cement.

●PLD series three‑bin automatic batching machine – accurately measures aggregates by proportion, with pneumatic gate and belt discharge modes to eliminate manual dosing errors.

●JS500 twin‑shaft compulsory mixer – uniformly mixes dry‑hard concrete and lightweight mortar, with high efficiency and easy maintenance.

●8‑meter belt conveyor – automatically feeds mixed material to the main hopper, with enclosed transport to prevent dust pollution.

●Automatic palletiser – handles 3–4 pallets of bricks at a time, stacking 4–5 layers; a forklift can transfer 10–20 pallets of finished bricks in one go, greatly reducing curing area and minimising manual handling damage.

●The feeding mechanism is 20% faster than traditional models, and the overall production efficiency of the entire line is increased by 20%.

6. Quality Assurance and After‑Sales Service

All components are manufactured and processed in strict compliance with international CE standards. Before delivery, each machine undergoes no‑load debugging and actual moulding trial runs; trial videos are provided to customers for verification. The manufacturer has a complete production workshop, finished goods storage area, and a professional quality control team, overseeing every stage from raw material processing, frame welding, and component assembly to final machine testing, ensuring stable delivery schedules.

Pre‑sales: Free plant layout planning, production capacity design, and local raw material formulation guidance.

During production: Real‑time progress updates.

After‑sales:

●12‑month warranty on core components (motors, oil pumps, PLC, etc.) – free repair or replacement.

●Wear parts (moulds, oil seals, chains, etc.) are supplied at competitive prices year‑round.

●Professional engineers can be dispatched for on‑site installation, commissioning, and worker training.

●Lifetime remote support for fault diagnosis and technical upgrades via online video.

The machine has been exported to more than 60 countries and regions in Southeast Asia, Africa, the Middle East, and the Americas. Its high cost‑performance ratio, durability, and high automation make it the preferred choice for global investors in non‑fired brick projects.
