Concrete Paver Block Making Machine

Concrete paver block machines are specialized equipment used to produce concrete paver blocks, bricks and other building materials. They are widely used in municipal engineering, landscaping, transportation and other fields.

1. Core Working Principle and Technical Features
- Forming Technology
Mainstream concrete paver block making machines utilize a combined vibration and pressure process. High-frequency vibration (acceleration up to 17.5G) densely packs the concrete particles. Simultaneously, hydraulic pressure (such as the QT6-15 model, which uses a layered material distribution and high-density dual-control design) is applied to ensure product strength and dimensional accuracy. Some high-end models incorporate a secondary material distribution system, enabling the production of colored paving blocks and layered structures, saving over 30% in material usage.
- Vibration System Design
There are two modes: table vibration and mold vibration.
Table vibration: Vibration is transmitted through a vibrating table. This is suitable for forming multiple blocks (for example, European models can form 18 blocks at a time), but the vibration power is relatively low (1-2.2kW per block).
Mold Vibration: The vibration source acts directly on the mold box, resulting in stronger excitation force (5-6.2kW per block), shortening molding time to 1-3 seconds, and achieving higher density, making it particularly suitable for the production of high-strength, load-bearing blocks.
- Automation Control
A PLC programmable controller and human-machine interface (such as the Japanese Mitsubishi system) are used to enable parameter presetting, fault diagnosis, and remote monitoring. Some models support variable frequency speed regulation, reducing starting current by 5-6 times, resulting in significant energy savings.

2. Classification and Typical Model Parameters
- Classification by Capacity and Automation Level
Small automatic machines, such as the QT4-15, produce approximately 35,000 standard bricks per shift, with prices starting at 10,000 dollars, making them suitable for small and medium-sized enterprises.
Large and medium-sized fully automatic machines, such as the QT6-15, produce 15 paving bricks (220×112.5×60mm) per shift, with a single-shift capacity of 600 square meters of paving bricks or 150 cubic meters of blocks. The equipment investment is 20,000-30,000 dollars, making them suitable for large-scale production.
- Classification by Forming Principle
Hydraulic drive: such as the QT series, offers stable pressure and high-strength products (95% compaction), but also higher maintenance costs.
Mechanical drive: such as cam-type models , offer a simple and durable structure, with a molding cycle of only 6-7 seconds, but the equipment weighs 17-32 tons and is expensive.
- Special Function Models
Multi-functional models: By replacing molds, they can produce over 20 types of products, including permeable bricks, slope protection bricks, and curbstones.
Environmentally friendly equipment: These machines can incorporate 30%-50% industrial waste (fly ash, slag, etc.), complying with national solid waste resource utilization policies.

3. Selection Recommendations
- Municipal projects:
Prefer fully automatic concrete paver block making machine models with secondary feeding (such as the QT6-15) to meet the needs of colored pavement tiles.
- Rural markets:
Semi-automatic hydraulic presses offer a more cost-effective solution suitable for low investment budgets.
- Environmental Requirements:
Pay attention to whether the equipment is ISO 14001 certified and the waste material content.

4. Typical Application Scenarios
- Municipal Engineering:
Permeable block making machines (such as the QT Series) produce permeable bricks with a porosity of 20%-30%, meeting the needs of sponge city construction.
- Water Conservancy Projects:
Slope Protection Brick Forming Machines (such as the QT6-15) can produce interlocking slope protection blocks with a 5-fold increase in erosion resistance.
- Rural Revitalization:
Small, mobile equipment supports on-site brick production, reducing transportation costs in remote areas.

Users are advised to select concrete paver block machine based on the specific needs, prioritizing the supplier's technical expertise and after-sales service network. For large-scale projects, a fully automated production line consisting of a mainframe + concrete batching plant + palletizing robot is recommended. This allows for unmanned production and increases overall efficiency by over 40%.
