Block Making Production Line

Modern construction projects demand consistent quality and high output, which is why our integrated Block Making Machine solutions form the backbone of efficient manufacturing plants. Whether you are scaling up a small yard or establishing a large precast facility, the transition to a Fully Automatic Block Making Machine eliminates manual inconsistencies and boosts daily capacity significantly. For operations targeting lightweight construction materials, pairing the line with an AAC Block Production Line PaPalletizing System ensures gentle handling and precise stacking of aerated concrete products. This level of coordination is only achievable when a Fully Automatic Concrete Block Making Machine is at the core, delivering uniform compaction and vibration that meet the strictest international standards.


The Block Making Production Line is engineered around a synchronized sequence of batching, mixing, molding, and curing stations that maintain a steady flow of raw materials to finished units. The system accommodates a wide range of block types—hollow, solid, paving, and curbstones—by using quick-change molds and programmable recipes. Critical process parameters are monitored through a central PLC interface, which tracks moisture levels, compaction time, and hydraulic pressure in real time to avoid rejections. The heavy-duty mixer guarantees homogeneous distribution of aggregates, while the automated transfer carts transport green products to the curing chamber with zero manual intervention. This design reduces labor dependency, lowers per-unit cost, and ensures that each block meets the required compressive strength and dimensional accuracy before it leaves the packaging station.

Key Production Parameters

  • Nominal capacity: 8 to 120 blocks per cycle, depending on mold configuration and block size (390×190×190 mm standard hollow block).
  • Cycle time: 15 – 22 seconds for fully automatic mode; adjustable based on product height and compaction settings.
  • Vibration system: Dual hydraulic motors with variable frequency (0–60 Hz), acceleration up to 90 kN for dense mix compaction.
  • Main hydraulic power: 22 kW energy-efficient unit with proportional control valves, operating pressure 21 MPa.
  • Mixer capacity: Stationary twin-shaft mixer, 500 L batch size, homogeneous mixing in 90 seconds, tolerance ±2% on cement ratio.
  • Pallet size: 1400×900×14 mm heat-treated steel pallets, magnetically clamped during feeding and molding.
  • Curing system: Direct steam injection or hot water circulation, temperature range 40–80 °C, controlled ramp-up for crack prevention.
  • Mold change time: Less than 8 minutes with hydraulic clamping and alignment guides, no heavy crane needed.
  • Control interface: 15-inch color touchscreen with remote monitoring capability, data logging for 120 days of production history.
  • Installed total power: 65–150 kW (configuration-dependent), 380–480 V / 50–60 Hz three-phase supply.

  • Road Paving Block Forming Machine

    Road Paving Block Forming Machine

    The road paving block forming machine is a core piece of equipment in municipal construction and environmentally friendly building materials production, specifically designed for producing concrete paving bricks, curb stones, grass pavers, and other bricks. The working principle of this type of brick-making equipment relies primarily on two technical modules: a vibration compaction system and a mold forming system. A vibrating motor generates high-frequency vibrations that rearrange concrete particles and expel air, while a hydraulic device applies vertical pressure to ensure the brick blank reaches the predetermined strength. Simultaneously, the equipment employs hydraulic static pressure forming technology, with a forming pressure exceeding 8MPa, ensuring the brick's density and compressive strength. A single mold can produce 24 standard bricks (240×115×53mm), with a forming cycle of 15-20 seconds and a daily output of up to 47,000 bricks. Through a quick mold-changing system, it can adapt to various sizes from 250×250×50mm to 1000×600×120mm, covering types such as sidewalk bricks, driveway bricks, and interlocking bricks.
