Fully Automatic Block Making Production Line
In the landscape of modern construction manufacturing, a Fully Automatic Block Production-Line redefines productivity by seamlessly integrating raw material batching, mixing, molding, cubing, and curing into one intelligent workflow. For operations that seek a more budget-friendly entry point, a Simple Block Making Production Line offers essential automation with straightforward controls, while a mid-range Automatic Block Production Line provides a scalable stepping stone. At the apex, the fully automatic configuration eliminates manual intervention across every station, delivering unmatched consistency and cycle speeds. When paired with elevated curing capacity, the Fully Automatic Block Production Line with Curing Rack optimizes space and accelerates strength development through automated rack transport and climate-controlled chambers, making it the definitive solution for high-volume precast plants.
The Fully Automatic Block Making Production Line is engineered around a central Siemens PLC control architecture, with a human-machine interface that allows recipe selection for over 50 block types without manual recalibration. Core specifications include a maximum molding area of 1200x900mm, a pallet size of 1400x1100mm, and a main hydraulic pressure of up to 25 MPa, enabling the production of solid bricks, hollow blocks, paving stones, curbstones, and interlocking tiles with a compressive strength exceeding 30 MPa after 28 days. The system achieves a typical dry-cycle output of 18–22 seconds per board, translating to a daily capacity of 8,000–12,000 standard hollow blocks (390x190x190mm) depending on mold configuration. Below is a detailed breakdown of technical parameters.

Material handling is fully automated from aggregate storage to finished product cubing. Weighing accuracy stays within ±1% through load cells on the aggregate batcher and cement silo screw conveyor. The block machine operates with a hydraulic clamping force of 1,200 kN and dual vertical vibration motors delivering 75 kN centrifugal force each. These elements, combined with forced pallet cleaning and an automatic oiling station, ensure every block meets dimensional tolerances of ±1.5 mm. The line also supports integrated pallet handling with a pallet stacker and destracker, reducing manual forklift trips and boosting overall safety.
