QT5-15 Automatic Cement Brick Making Machine
Overview of QT5-15 Automatic Cement Brick Making Machine
The QT5-15 Automatic Cement Brick Making Machine is a heavy-duty, high-efficiency block production solution designed for the global construction market. As a professional manufacturer of fully automatic cement brick making machines, we build this system to deliver maximum output, outstanding density, and continuous operational reliability with minimal labor overhead.



Working Principle and Operational Technology
The QT5-15 combines dynamic hydraulic pressure with high-frequency multi-directional vibration to ensure ideal compaction and dimensional precision.
- Hydraulic Pressing & Vibration Integration: Ensures consistent density, smooth surfaces, and higher compressive strength across all brick types.
- Fully Automated Process: Synchronized mechanical, hydraulic, and electrical systems handle feeding, pressing, molding, and pallet discharging automatically.
- Rapid Shaping Cycle: High-response hydraulic valves achieve fast molding cycle times of 15 to 20 seconds, drastically boosting overall output.
Applicable Raw Materials and Mix Ratios
Engineered for resource versatility, the machine processes various low-cost local materials and industrial by-products efficiently:
Usable Materials: Sand, gravel, crushed stone, cement, fly ash, slag, gangue, stone dust, and recycled construction waste.
Standard Concrete Block Ratio: 10%–15% Cement, 30%–40% Sand, and 45%–55% Crushed Stone (0–5 mm).
Eco-Friendly Fly Ash Ratio: 10%–15% Cement, 35%–45% Fly Ash, and 40%–50% Stone Dust or Sand.
