Main Features
1. Broad Application: QTJ4-40 Small free brick machine can be widely used with slag, sand, gravel, aluminum red slag, electrolytic copper slag, construction waste, volcanic slag, and other raw materials. Raw materials are abundant, rich, and can be seen everywhere, making investment and setting up a factory extremely convenient.
2. Advanced Vibration System: In addition to the frame itself, the suspension and connection parts of the whole machine use springs. Vibration molding achieves four-tube vibration under the indenter, mold box, mold core, and plate, ensuring high compactness and uniformity of the product, stable operation, low noise, and a good vibration reduction effect.
3. Precise Indenter Movement: The indenter can move longitudinally, making it easy to feed, maintain, and wash. The indenter drop distance is small (only 20mm). This ensures the gap between the press foot, box, and core is minimal so blocks have no large rough edges, and it reduces damage to the core.
4. Convenient Mold Replacement: Mold replacement is highly convenient. By changing molds, the machine can produce 240, 140, 115 standard bricks and other different specifications of blocks and roadside stones. It can also be customized according to user requirements for various special-shaped molds.
5. Durable Wooden Pallets: The wooden pallet at the bottom synchronously resonates with the box core when forming and is not affected by impact forces. As a result, the lifespan of the wooden pallet is more than twice that of similar products.

Frequently Asked Questions (FAQ)
What raw materials can the QTJ4-40 block machine use?
The machine is highly versatile and can process a wide variety of abundant raw materials, including slag, sand, gravel, aluminum red slag, electrolytic copper slag, construction waste, and volcanic slag.
What is the production cycle time for this machine?
The QTJ4-40 small free brick machine operates efficiently with a molding cycle time of just 40 seconds per batch.
Can I produce different types of bricks with the same machine?
Yes, mold replacement is very convenient. By changing the molds, you can produce standard bricks (240, 140, 115 sizes), various hollow blocks, roadside stones, and even custom special-shaped blocks according to your requirements.
What are the power requirements and total mass of the machine?
The machine requires an electrical source of 380V/50Hz (adjustable) with a total power consumption of 8.8 KW. The overall mass of the equipment is 1200 KG.
How many standard bricks can it produce in an 8-hour shift?
For standard bricks (240*115*53mm), the machine produces 21 pieces per mold, equating to 1,890 pieces per hour, resulting in a total capacity of 15,120 pieces per 8-hour shift.
Why does the wooden pallet last longer on this machine?
The wooden pallet at the bottom is designed to synchronously resonate with the box core during forming. Because it is not subjected to direct impact forces, its lifespan is extended to more than twice that of similar products on the market.
