What is the QT4-25C Block Machine?
The QT4-25C automatic concrete making machine price is a automatic concrete block making machine that is capable of producing various types of concrete blocks such as hollow blocks, solid blocks, paver blocks, and curbstones by simply changing the mold. It is known for its hydraulic press system, electrical control, and high production efficiency.
Step-by-Step: How It Works
1. Raw Material Preparation
The machine requires a mix of sand, cement, water, and gravel — the basic ingredients for concrete. These materials are usually mixed in a concrete mixer before feeding into the machine.
Materials used:
- Cement
- Sand
- Stone chips or gravel
- Water
Tip: The quality of raw materials directly affects the strength and durability of the final blocks.
2. Feeding the Material
Once the concrete is ready, it’s loaded into the hopper of the QT4-25C. The feeder car distributes the concrete into the down mould.
- The vibration motor ensures that the concrete fills evenly.
- The feeder box moves back and forth to enhance uniform distribution.
3. Molding and Vibration
After feeding, the mold box comes down，This is where the magic happens.
- The high-frequency vibration make the material into a solid block.
- This dual compaction ensures high strength and precision of the block dimensions.
The QT4-25C can produce up to 5800 blocks per 8-hour shift, depending on the block type and mold used.
4. Demolding
Once the blocks are formed, the upper mold rises and the bottom pallet moves the newly made blocks out of the machine. These blocks are now ready for curing.
- The blocks are placed on pallets and moved to a curing area.
- Typically, they are cured for 7–14 days to achieve optimal strength.
5. Stacking and Storage
After curing, the blocks are ready to be stacked and transported for use or sale. The QT4-25C’s consistent block quality makes it ideal for both small and large-scale production operations.
