What is a Fly Ash Brick Making Machine?

A fly ash brick making machine combines materials like fly ash, lime, gypsum, and sand or stone dust in specific proportions, creating a uniform mix. The machine then applies high-pressure compression—usually around 100-150 kg/cm²—to form strong, durable bricks. With advanced automation, this process minimizes manual labor, enhancing efficiency and consistency in brick production.

Fly ash bricks offer several advantages over traditional clay bricks:

  • Lighter: Easier to handle and transport.
  • Stronger: Higher compressive strength.
  • More Durable: Resistant to weathering and wear.
  • Cost-Effective: Lower production costs compared to clay bricks.
  • Eco-Friendly: Utilizes fly ash, reducing waste in landfills.

Our range of machines includes both hydraulic and vibration compaction models, with production capacities ranging from 5,000 to 60,000 bricks per day, depending on the model.

What are Fly Ash Bricks?

Fly ash bricks are a type of building material made from fly ash, a byproduct of coal combustion. They are known for their durability, strength, and eco-friendliness. There are three main types of fly ash bricks based on the raw materials and curing methods used:

Autoclaved fly ash bricks

These bricks are made from a mixture of fly ash, quicklime, gypsum, and aggregates like cinder. The mixture undergoes hydration, is milled, and then formed under high pressure using a hydraulic press. The bricks are cured using steam, either under normal or high pressure. They have high compressive strength, ranging from 10 MPa to 20 MPa, and can withstand up to 15 freeze-thaw cycles. The continuous hydration reaction in a humid environment helps improve their strength over time.

Steam-Free and Burn-Free Fly Ash Bricks

These bricks use cement as the main binding material along with fly ash, slag, stone powder, sand, and gravel. They are formed using a vibrating concrete brick machine and naturally cured to achieve a strength of up to 15 MPa. This method is suitable for low-investment projects.

natural curing fly ash bricks

Clay-containing Fly Ash Bricks

Made from a mix of fly ash, industrial slag, and clay, these bricks are extruded by a vacuum clay brick machine and then burned at high temperatures. The combustion of fly ash and slag within the bricks reduces the need for additional fuel, making the process energy-efficient. These bricks offer excellent bending resistance, compression resistance, and insulation properties, with a compressive strength of 16.68 MPa.

What are Fly Ash Bricks Machines?

A fly ash brick machine automates the production of fly ash bricks, reducing manual labor and increasing efficiency. These machines are essential for manufacturers looking to scale production or reduce costs. The types of machines include:

  • Static Press Brick Machine: Used for producing steam-cured fly ash bricks.
  • Vibrating Concrete Block Machine: Used for producing steam-free fly ash bricks.
  • Vacuum Clay Brick Machine: Used for producing burned clay fly ash bricks.

differences from others brick machine

These machines handle raw material feeding, mixing, and brick forming with minimal supervision, thereby enhancing production efficiency and consistency.

Why Should You Use Fly Ash Bricks?

Fly ash bricks are a sustainable alternative to traditional building materials, offering numerous benefits. These bricks are made from fly ash, a byproduct of coal combustion and is used in various applications, including soil stabilization and concrete production. Particularly, fly ash bricks offers several advantages:

  • Eco-friendly: Utilizes industrial waste, reducing environmental impact.
  • Cost-effective: Lower production costs compared to traditional bricks.
  • Durable and Strong: High compressive strength and resistance to environmental conditions.
  • Versatile: Can be used in various construction applications, from residential buildings to industrial structures.

fly ash samples

Using fly ash in brick production not only promotes sustainability but also enhances the quality and longevity of the building materials.

What are the Raw Materials used in the Production of Fly Ash Bricks?

Quicklime

Quicklime is the primary raw material for autoclaved fly ash bricks. It activates the fly ash, imparting necessary physical and mechanical properties to the bricks.

  • Calcium Content: Higher calcium content in lime reduces production costs and enhances brick quality.
  • Fast Hydration: Quicklime shortens the digestion process, boosting production efficiency.
  • High Digestion Temperature: Elevated temperatures during digestion improve brick strength before steam curing.

quicklime samples

Gypsum

Gypsum accelerates the hydration reaction, enhances crystallization, and improves early brick strength, especially flexural strength.

  • Fineness Requirement: 88um sieve with a sieve residue not exceeding 15%.
  • Calcium Sulfate Content: Should be ≥ 65%.
  • Sources: Natural gypsum and industrial waste gypsum like desulfurized gypsum.
  • Dosage: Determined based on the desired brick strength.

How to Produce Fly Ash Bricks – The Manufacturing Process

Producing fly ash bricks using a manufacturing machine can be straightforward if you follow the proper steps. Here is a detailed guide to help you understand the process:

  1. Preparing the Raw Materials:
    • Hydrated Lime: Add hydrated lime powder to the fly ash.
    • Gypsum: Mix gypsum into the blend.
    • Quarry Dust: Incorporate quarry dust into the mixture.
  2. Mixing:
    • Combine fly ash, quarry dust, hydrated lime, and gypsum in a pan mixer.
    • Add the required amount of water to ensure thorough mixing. Refer to the appropriate mixing ratios mentioned above.
  3. Transferring the Mixture:
    • After mixing, transfer the mixture to the hopper of the fly ash brick-making machine via a conveyor belt.
  4. Forming the Bricks:
    • The mixture is moved into the cavity of the fly ash brick press machine.
    • The machine presses the materials to form bricks with the desired shape and size.
  5. Ejection:
    • The formed bricks are ejected from the machine and are ready for the curing process.

autoclave fly ash brick production line

Steam Curing Fly Ash Bricks

Autoclaved fly ash bricks require curing, which can be done in two ways:

  1. Normal Pressure Steam Curing:
    • Bricks are cured using steam at normal atmospheric pressure.
    • This method is suitable for smaller production scales and can be more cost-effective.
  2. High-Pressure Steam Curing (Autoclaving):
    • Bricks are cured in an autoclave with high-pressure steam.
    • This method enhances the strength and durability of the bricks and is ideal for large-scale production.

By following these steps, you can efficiently produce high-quality fly ash bricks. The process is similar to making concrete blocks, ensuring that the right proportions and proper curing methods are applied to achieve the best results.

Differences of Fly Ash Bricks Steam Curing Method.

Steaming Method Saturated Steam Pressure/MPA Curing Temperature/℃ Maintenance Equipment Cost of Equipment Product Quality Product Cost
Normal Pressure 0.1 95-100 Steam Curing Room Low Meet the Standard High (More Lime Consumption)
High Pressure 0.9 ~ 1.6 174-200 Autoclave High Better Performance Low (Less Lime Consumption)
