This sophisticated equipment combines hydraulic power, automated controls, and precision engineering to produce high-quality construction blocks efficiently. The machine’s operation involves a systematic process of material feeding, mixing, molding, and curing, all controlled through an integrated automation system that ensures consistent quality and high production output.
Operating Principles and Core Components
Material Handling System
The QT12-15 Automatic Block Machine begins its operation with an advanced material handling system. The machine integrates seamlessly with a cement silo and the PLD1200 concrete batching machine, ensuring precise material proportioning. The system automatically measures and combines raw materials including cement, aggregates, and additives according to predetermined mix designs. This precision in material handling is crucial for maintaining consistent product quality. The 750-liter concrete mixer ensures thorough blending of all components, creating a homogeneous mixture that’s essential for producing durable blocks. The automated nature of this system minimizes human error and reduces labor requirements, typically needing only 4-5 workers to operate the entire production line.
Hydraulic Compression Technology
At the heart of the QT12-15 automatic block machine lies its sophisticated hydraulic compression system. This system utilizes powerful hydraulic cylinders that apply consistent pressure across the mold cavity, ensuring uniform density throughout each block. The machine features two or four electric motors for vibration, which work in conjunction with the hydraulic system to achieve optimal material compaction. This combination of hydraulic pressure and vibration eliminates air voids and creates blocks with superior strength and dimensional accuracy. The system’s precision control allows for adjustable compression forces, enabling the production of blocks with different density requirements for various applications.
Automated Production Control
The control system of the QT12-15 automatic block machine represents the pinnacle of automation in block manufacturing. It features a programmable logic controller (PLC) that manages every aspect of the production cycle, from material feeding to product ejection. The system monitors key parameters such as mixing time, vibration frequency, and compression pressure in real-time, making automatic adjustments to maintain optimal production conditions. The machine’s interface allows operators to easily switch between different product specifications, with the capability to store multiple production recipes for quick changeover between different block types.
Production Capabilities and Versatility

The QT12-15 automatic block machine demonstrates remarkable production efficiency, capable of producing 23,040 eight-inch blocks or 124,800 solid bricks (240x115x50mm) in an eight-hour shift. This high output is achieved through optimized cycle times and continuous operation capabilities. The machine’s automated pallet feeding system and block cuber work in perfect synchronization to maintain this impressive production rate. The efficiency is further enhanced by the machine’s ability to operate continuously with minimal downtime, requiring only routine maintenance breaks. The production line’s layout is optimized for a factory area of 2500-6500 m², ensuring smooth material flow and efficient space utilization.
Mold Versatility and Product Range
One of the most significant advantages of the QT12-15 automatic block machine is its exceptional versatility in mold options. The machine accommodates a wide range of interchangeable molds, enabling the production of hollow blocks, solid bricks, color paver bricks, and curbstones. Each mold is engineered for quick replacement, minimizing downtime during product changeovers. The machine maintains consistent quality across all product types through precise control of compression and vibration parameters. This versatility allows manufacturers to respond quickly to market demands and maintain a diverse product portfolio without additional equipment investment.
