Medium-to-large building material enterprises and corporate clients |
● You have a limited budget (under 100,000 RMB)
● You have limited space (a few dozen square meters)
● Your demand is sporadic (for personal use or small-scale sales)
● You want to test the market and validate demand first
● Local labor costs are extremely low
● You have specific major clients or long-term orders
● You have a substantial budget (over 1 million RMB)
● You prioritize product quality and brand premium
● You aim for large-scale operations and long-term growth
● There are abundant local industrial waste resources available for use
● You value automation and wish to reduce reliance on manual labor
Regions with developing infrastructure (e.g., Africa, Central Asia, Latin America): Meeting the brick requirements for small-scale construction projects, such as self-built homes and boundary walls for local villagers.
On-site support for large-scale projects: Deploying a small brick-making machine near the construction site—during road, bridge, or water conservancy projects—to utilize local sand, gravel, and waste materials for producing items like curbstones or slope protection bricks.
Complementary role for concrete product plants: While large factories use heavy machinery for standard components, small machines are used to produce custom, irregular, or specialized bricks, thereby avoiding the energy waste associated with operating large-scale equipment.
Small-scale machines lack automatic metering systems, so ingredient preparation relies entirely on manual experience; therefore, the simpler the formula, the better.

Notes |
|
Standard hollow block |
1 bag (50 kg) |
6–7 shovel loads (approx. 300 kg) |
As needed |
Most common; suitable for beginners |
|
Solid standard brick |
1 bag (50 kg) |
5–6 shovel loads (approx. 250 kg) |
As needed |
Higher cement content; high strength |
|
Paving brick |
1 bag (50 kg) |
5 shovel loads (approx. 250 kg) |
As needed |
Small amounts of pigment can be added for coloring |
Note: Shovel capacities vary; first make a few test bricks to determine the ratio best suited to your shovel, then standardize it.

Issues Observed |
Most Likely Causes |
Quick Solutions |
|
Brick green body crumbles upon handling |
Insufficient water / Insufficient cement / Inadequate vibration |
Add water and remix / Increase cement ratio / Extend vibration time by 3–5 seconds |
|
Brick green body collapses after demolding |
Excessive water / Demolding too soon |
Reduce water content / Slow down demolding speed |
|
Brick green body surface has numerous air pockets |
Over-vibration / Mix too dry |
Shorten vibration time / Add water as appropriate |
|
Brick green body is uneven (higher on one side than the other) |
Uneven pallet / Mold not level |
Replace with a flat pallet / Level the equipment |
|
Brick green body sticks to the mold during demolding |
No release agent applied / Residue in mold cavity |
Apply release agent after each demolding / Thoroughly clean the mold cavity |
|
Abnormally loud vibration noise |
Loose bolts / Lack of bearing lubrication |
Stop the machine immediately to check and tighten bolts / Apply grease |
|
Sudden drop in production output |
Operator fatigue / Mold blockage |
Take shift breaks / Clean the mold |
