An Automatic Hollow Block Making Machine is an advanced industrial system engineered to produce hollow concrete blocks with minimal manual intervention. These machines automate the entire block-making process—including raw material feeding, batching, mixing, molding, vibration compaction, and block ejection—using PLC (Programmable Logic Controller) or computerized control systems for high efficiency and consistent quality.Full Automation: All major operations are controlled automatically, reducing labor requirements and ensuring precise, repeatable production cycles.Hydraulic & Vibration Compaction: Utilizes powerful hydraulic pressure (up to 21–25 MPa) and high-frequency vibration (up to 100 kN, 3800–4500 r/min) to create dense, strong, and uniform hollow blocks.Production Capacity: Capable of producing thousands of blocks per shift. For example, some models can output 2,160–2,880 hollow blocks per hour (size 400×200×200 mm), or up to 23,000+ blocks in an 8-hour shift, depending on block size and machine configuration.Versatility: By changing molds, the machine can manufacture various products including hollow blocks, solid bricks, paver blocks, curbstones, and more.Material Flexibility: Can process a wide range of raw materials such as cement, sand, stone dust, fly ash, slag, and other industrial wastes, supporting eco-friendly construction.Precision & Quality: Delivers blocks with tight dimensional tolerances (often within 1 mm), high compressive strength, and uniform finish, meeting industry standards such as BIS 2185-1 (2005).Robust Construction: Built with heavy-duty steel frames and quality components for durability and continuous industrial use.
