QT15 Automatic Interlocking Paver Production Line
The QT15 Automatic Interlocking Paver Production Line is a heavy-duty block making machine designed with a large 1400 × 1200 mm pallet, allowing larger molds and more concrete blocks per cycle. This advanced pallet design significantly increases daily production capacity, making the QT15 an ideal automatic block machine for interlocking pavers, paving blocks, and special concrete products such as slope protection blocks. As a high-performance brick machine, the QT15 block making machine is equipped with an advanced servo vibration system, featuring 4 sets of 7.5 kW servo vibration motors. This combination delivers high forming efficiency with precise compaction control. Together with full-line automation and a reinforced industrial structure, this automatic block making machine ensures consistent product quality, stable output, and long-term reliability for medium- to large-scale concrete block and brick production plants. 1. High-Capacity Production with Large Pallet Design
The 1400 × 1200 mm pallet size plays a key role in achieving high productivity for this concrete block machine:
Higher output per cycle using large and multi-cavity molds Efficient production of interlocking pavers, road pavers, and slope protection blocks Flexible mold configurations for diversified concrete block and brick products Stable dimensions and uniform surface finish for paving bricks and blocks The fully automated production process of this automatic brick making machine reduces manual labor, improves operational safety, and ensures smooth, continuous production.
2. Core Technology & System Configuration
Batching and Mixing System
Automatic batching system for precise weighing and mixing of cement, aggregates, sand, and additives, ensuring a uniform and stable concrete mix for the block making machine. The QT15 is equipped with a planetary mixer, which guarantees high mixing uniformity and is suitable for high-strength paving bricks, interlocking blocks, and slope protection blocks. QT15 Automatic Interlocking Paver Machine
The core QT15 block making machine is optimized for large pallets and heavy molds, providing strong forming pressure and reliable output under continuous industrial operation.
Servo Vibration System
The QT15 brick making machine features an advanced servo-controlled vibration system with 4 sets of 7.5 kW servo vibration motors. By combining static pressing with dynamic vibration, this system significantly improves concrete density, compressive strength, and surface quality. It ensures excellent consistency for interlocking blocks and architectural paving bricks while enhancing repeatability and energy efficiency. Heavy-Duty Mechanical Structure
A reinforced steel frame ensures rigidity, stability, and long service life of the block machine, even under intensive daily production conditions.
Hydraulic System with Oil Cooler
Featuring Japanese Yuken proportional and directional valves, the hydraulic system enables accurate flow and pressure control via the touch panel. Dual vane pumps support simultaneous movements, while high-performance American ALBERT pumps provide stable and reliable pressure. The hydraulic station is equipped with an oil cooler, ensuring stable operation under high ambient temperatures and long-term continuous use for the brick making machine.
Material Feeding System
Bottom material feeding ensures even compaction and high structural strength of concrete blocks Face material feeding allows uniform application of colored or decorative concrete for paving bricks Electrical Control System
Based on German automation technology, the QT15 automatic block machine integrates Siemens PLC and HMI for precise control and simplified operation. Switzerland ABB relaysensure safe signal transmission and a low failure rate.
Automatic Pallet Provider & Automatic Stacker
The automatic pallet provider supplies empty pallets to the block machine continuously, ensuring smooth production. Freshly formed concrete blocks and bricks are then automatically stacked layer by layer by the automatic stacker, optimizing curing space, minimizing manual handling, and enhancing overall site safety.
