Hollow Brick Machinery
In modern construction, the demand for high-strength, lightweight building units has driven rapid innovation in hollow brick production technology. Our state-of-the-art hollow brick machinery integrates precision vibration, hydraulic compaction, and automated material feeding to deliver consistent quality and impressive output. This system shares its core engineering DNA with our proven Cement Block Molding Machinery, yet it is specially calibrated to form hollow cores that reduce weight and improve thermal insulation. For operations looking to scale up without sacrificing accuracy, the Automatic Block Molding Machine variant offers seamless PLC-controlled sequences, minimizing manual intervention. When fully integrated into a high-capacity line, our Automatic Block Molding Machinery handles everything from batching to cubing, reinforcing its role as the backbone of efficient production. Builders and manufacturers alike recognize that the heart of any reliable plant is a robust Block Making Machine, and our hollow brick solutions are engineered to meet the same rigorous standards, delivering precision-formed units cycle after cycle.
The Hollow Brick Machinery lineup is built around a heavy-duty steel frame that withstands intense vibration forces while maintaining dimensional accuracy. Each model uses a synchronized vibration table and hydraulic head to achieve rapid compaction of dry-mix concrete, resulting in dense, sharp-edged hollow bricks and blocks. The interchangeable mold sets allow production of various hollow sizes, including 390x190x190 mm, 290x140x190 mm, and other customized profiles, making it simple to adapt to regional building codes. Below you will find the core technical parameters that showcase the engineering depth behind these machines.
- Vibration Method: Platform vibration combined with synchronous hydraulic compaction
- Control System: Siemens PLC with touch screen interface for real-time monitoring
- Hydraulic Pressure: Up to 21 MPa, ensuring uniform density across the block height
- Cycle Time: Adjustable from 15 to 25 seconds depending on block height and mixture
- Mold Change Time: Quick-change hydraulic clamping system, typically under 10 minutes
- Raw Materials: Cement, crushed stone, sand, fly ash, and various lightweight aggregates
- Pallet Type: Hardwood or PVC pallets, precision ground to maintain flatness
- Sound Insulation: Integrated rubber dampers reduce noise emission below 85 dB

All models feature continuous mixing and conveyor integration, enabling consistent material supply for uninterrupted operation. The vibration motor and eccentric shaft are dynamically balanced to extend bearing life and maintain accurate amplitude. The mold box is precision machined with hardened steel liners, ensuring a tight seal and clean demolding every time. A digital weight sensor provides real-time feedback on material dosage, keeping block density within a ±2% tolerance band. This Hollow Brick Machinery design also incorporates a centralized greasing system, which drastically reduces daily maintenance time and helps the line achieve a utilization rate above 93%.
