Our hollow bricks machine has been developed as a top-tier concrete brick making machine that meets the rigorous demands of modern construction. By merging high-frequency vibration with hydraulic compression, the unit works effectively as a brick press machine, forming dense, uniform hollow blocks in seconds. The design draws on proven principles found in advanced brick moulding machines, ensuring every block has sharp edges and consistent dimensions. As a fully integrated brick manufacturing machine, it automates feeding, pressing, and demolding, slashing labor costs while boosting daily output to thousands of blocks. The robust frame and wear-resistant molds extend service life, even under continuous operation with abrasive materials like fly ash, sand, and crushed stone.
The hollow bricks machine distinguishes itself through smart control and fast mold-swap capability. An integrated PLC panel lets operators adjust vibration frequency, pressure, and cycle time for different block sizes—such as 390×190×190 mm hollow bricks or solid pavers—without mechanical changes. The hydraulic system maintains steady pressure across the entire mold surface, minimizing material waste and ensuring block density exceeds 2,200 kg/m³. A rapid pallet feeder and automatic stacking arm further streamline the production line, making it easy to integrate with existing concrete mixers and conveyors. Energy consumption stays low thanks to a variable-frequency drive on the main motor, while the centralized lubrication system cuts daily maintenance to a fraction of what older presses require. Whether you produce hollow bricks, interlocking blocks, or curb stones, this single machine adapts in minutes, giving you the flexibility to respond to shifting market demand.
