Concrete Block Making Machinery

In modern masonry production, upgrading to efficient Concrete Block Machines dramatically reduces per-block costs and cycle times. Our flagship Fully Automatic Block Making Machine leverages hydraulic compression and intelligent weighing to deliver repeatable block quality without operator intervention. For high-volume plants, the complete Fully Automatic Block Making Machinery line integrates aggregate batching, pan mixing, wet casting, and cube stacking, turning raw materials into packaged blocks on a single synchronized platform. Smaller operations benefit from the versatility of the Automatic Block Making Machine, which balances affordability with automated feeding and demolding. Below is a detailed breakdown of the performance parameters and engineering advantages you can expect.


The Concrete Block Making Machinery is constructed around a rigid welded frame that resists torsional stress during high-frequency vibration. Twin eccentric shafts generate an adjustable vibration force between 7.5 kN and 15 kN, compacting semi-dry concrete into dense, homogeneous blocks. A proportional hydraulic circuit maintains pressing pressure up to 25 MPa, which is essential for producing interlocking pavers with sharp edges and low water absorption. The standard PLC interface stores over 50 mold recipes, each with dedicated settings for feed time, vibration duration, and pressing stroke. Materials such as quarry dust, recycled aggregate, slag, and expanded clay can be processed without hardware changes. Below are the core specifications that define our current product range.

    ‌‌Concrete Brick Machine Equipment

    ‌‌Concrete Brick Machine Equipment is a mechanical equipment used to produce concrete bricks, mainly including cement brick machines, hollow brick machines, colored pavement brick machines and other types. These equipment usually use stone powder, fly ash, slag, slag, gravel, sand, water and other raw materials, and press them into shape through hydraulic or vibration methods.
  • Brick Stacking Machine

    Brick Stacking Machine

    The Brick Stacking Machine is a piece of smart brick-stacking equipment designed using patented technology that employs a palletizing pattern with pre-set spacing. This system was developed to address the limitations of basic block production lines—specifically the reliance on manual labor for stacking finished bricks, which entails high physical exertion and low efficiency, as well as the need for mechanized loading and unloading of finished products. Typically, the system is installed independently near the product curing yard to stack cured products on-site; alternatively, it can be integrated directly into the block production line to enable in-line palletizing.
