Brick Making Machine User Guide: Avoid These 3 Mistakes to Significantly Improve Brick Quality

Many brick factories suffer from inconsistent product quality, often not due to the equipment itself, but rather to deeply ingrained operational mistakes. Here are three of the most fatal mistakes and their solutions:

Mistake 1: Raw Material Proportioning Based on "Feeling," Ignoring Scientific Principles

Incorrect Practice: Failing to accurately proportion raw materials, relying solely on experience to estimate the amounts of cement, aggregates (sand, stone powder, cinders, etc.), and water.

Disastrous Consequences: Vastly varying brick strength. Insufficient cement results in insufficient strength, causing bricks to crumble easily; improper aggregate gradation leads to poor density; uncontrolled moisture content either prevents molding or results in numerous air bubbles and cracks.

Solutions:

Strict Measurement: Use scales or fixed-volume containers to ensure accurate proportions for each batch.

Optimized Gradation: Use aggregates of different particle sizes to mix, allowing finer particles to fill the gaps between larger particles, achieving maximum density.

Controlled Water-Cement Ratio: Minimize water usage while ensuring successful molding. The lower the moisture content, the higher the hardened strength.

Myth 2: Neglecting aging and mixing, pressing with uneven mixing.

Incorrect practice: Roughly mixing the raw materials and immediately feeding them into the brick-making machine for pressing.

Disadvantages: Uneven mixing of raw materials prevents cement from fully coating each aggregate particle, resulting in weak points within the brick. The overall strength of the brick is low, making it prone to delamination and cracking.

Solution:

Ensure sufficient mixing time: Use a forced mixer to ensure sufficient mixing time, achieving a uniform state where the raw materials can be formed into a ball by hand but crumble easily when dropped.

Aging: Let the mixed raw materials stand (age) for at least 2 hours to allow moisture to fully penetrate into each particle. This not only benefits pressing but also effectively prevents cracking later.

Myth 3: Blindly pursuing speed, neglecting vibration/static pressing time.

Incorrect practice: In pursuit of output, arbitrarily shortening the vibration or static pressing time during brick forming.

Disadvantages: This is the direct cause of "brittle" bricks. Insufficient pressure and time prevent the full expulsion of air from between materials, resulting in poor particle bonding and extremely low brick density.

Solution:

Ensure "Effective Pressure Time": Strictly adhere to the equipment manual and technical procedures, ensuring sufficient vibration and pressure holding time for each pressing operation. This trades "time" for "strength" and "quality."

Quality over Speed: Appropriately reduce the production pace to ensure each brick is thoroughly compacted. High-quality bricks fetch a better price, far more profitable than producing a pile of defective products.

Summary: The secret to improving brick quality lies not in purchasing the most expensive machinery, but in scientific and standardized process control.

Precise proportions are fundamental, uniform mixing is the guarantee, and thorough pressing is crucial.

Avoid these three pitfalls, and your bricks will achieve a qualitative leap in both strength and appearance.
