Hollow brick machine equipment supplier

Hollow brick machine suppliers play an extremely important role in the construction materials production industry.

Hollow bricks have become a popular product in the market due to their excellent thermal insulation performance, lighter weight, and good environmental characteristics. Choosing a reliable hollow brick machine supplier is crucial for ensuring production efficiency and product quality. The following is an introduction to the hollow brick technology by HAMAC.

Introduction to Brick Production Line Projects
Efficiently utilize fly ash, slag, stone powder, desulfurization ash, slag, coal gangue, phosphogypsum, tailings sand, and other materials to produce new types of wall materials such as steam-pressed fly ash bricks, steam-pressed ash sand bricks, and aerated concrete products. It is also used in the production of high-ash content fly ash sintered bricks, coal gangue sintered bricks, stone powder bricks, construction waste bricks, life incineration waste slag bricks, waste soil bricks, and various blocks, comprehensive utilization of power plant desulfurization gypsum, etc., making it the preferred choice for large-scale, automated, and modern waste utilization brick production lines.

High-Ash Content and Multi-Variety Waste Utilization Brick Technology
HAMAC relies on authoritative research institutes for technical support and has a production process service technical team to provide comprehensive technical support to users. Over the years, it has developed effective technological approaches for high-ash content utilization and multi-solid waste utilization to manufacture new wall materials, establishing a mature and complete industrial system.
Using fly ash/tailings sand/desulfurization ash/slag/ore slag/stone waste/electrolytic slag/phosphogypsum to make bricks, with a waste utilization rate of over 90%, each production line can handle nearly 100,000 tons of solid waste per year, producing high-quality products (strength ≥ 20Mpa) at low cost. The main equipment of the production line can produce different specifications of porous bricks and hollow blocks by changing molds.
This production line is also suitable for the production of other steam-pressed or sintered wall materials made from solid waste materials, such as high-ash content fly ash sintered bricks, coal gangue sintered bricks, construction waste bricks, life incineration waste slag bricks, waste soil bricks, various blocks, and comprehensive utilization of power plant desulfurization gypsum.

Complete Line Process Technology
HAMAC’s engineering department can provide different materials’ steam-pressed brick production process technology solutions, aerated concrete block production line technology solutions, overall planning solutions, and related production process formulas according to the customer’s raw materials and site conditions. It can also provide process design services during the construction drawing stage.
Solid waste is complex, low in activity, and not easy to shape. Only by using scientific proportions and optimized combinations, and pressing it with hydraulic press in both directions at high pressure, can a high-density, high-initial-strength blank be formed. Then, under steam-press conditions, a silico-calcium compound reaction occurs to form tobermorite crystals, making the products have high strength, low drying shrinkage, strong frost resistance, and durability, becoming qualified building products.

Production of Hollow Brick Raw Material Ratios
With the rapid development of the economy, the building materials industry has also made great progress, and new types of hollow bricks have also won more and more markets. It is precisely because of the hot market for hollow bricks that has ignited the enthusiasm of many investors. However, many friends do not understand the raw materials and formulations for producing hollow bricks. Here, I have compiled some information on raw materials and related formulations for hollow bricks for everyone’s reference.

Hollow brick raw material ratios:
Formula 1, fly ash brick: coal ash 30%, slag 30%, stone nitrate 30%, cement 8-10%, rock sand fine 0.2% (100kg/cm2 + 8% cement, 150kg/cm2 + 10% cement).
Formula 2, stone nitrate brick: stone powder 60%, stone nitrate 3%, cement 8-10%, hydrated lime 3%, lime powder 0.2%.
Formula 3, river sand brick: ① River sand 60%, stone powder 30%, cement 10-15%, mortar treasure 0.5%. ② Lime powder king 0.2%, early strength agent 0.2%, potassium chloride 0.2% (choose one).
Formula 4, shale brick (crushed): shale 90%, cement 8-10%, rock sand 0.2%, potassium chloride 0.2%.
Formula 5, pyrite powder: pyrite powder 60%, stone powder 30%, cement 10-15%, rock sand fine 0.2%, potassium chloride 0.2%, early strength agent 0.2%.
Formula 6, high-ash content fly ash brick: fly ash 60%, slag 30%, cement 8-10%, rock sand fine 0.2%, early strength agent 0.2%.

Currently, HAMAC’s series of fully automatic hydraulic machines are used in nearly a thousand production lines in 30 provinces and cities across the country, including electric power, chemical industry, metallurgy, mining, building materials, and other industries, forming a mainstream market effect and exporting to multiple countries including Russia. The annual production scale of load-bearing wall materials exceeds 10 billion standard bricks, with an annual solid waste utilization of about 30 million tons, reducing the destruction of fields by about 5,000 acres, and saving 500,000 tons of standard coal, showing significant economic and social benefits.
