◦ By Production Scale: There are large – scale, medium – scale, and small – scale brick – making machines, meeting different production needs. Small brick – making machines are suitable for small – scale workshops, and large – scale brick – making machines are suitable for large – scale building material factories.

• Notable Advantages:

◦ Wide and Environment – friendly Raw Materials: Can efficiently utilize industrial solid wastes such as fly ash, furnace slag, stone powder, and tailing sand, with a high waste utilization rate (some reaching more than 90%), contributing to environmental protection and also reducing raw material costs.

◦ Rich Products: By changing molds, various brick types such as porous bricks, hollow blocks, curb stones, and colored pavement bricks can be produced, suitable for different scenarios such as construction and roads.

◦ Automation and High Efficiency: Fully automatic models realize man – machine dialogue, remote fault diagnosis, etc. The production process is continuous, shortening working hours and increasing production output. For example, some brick – making machines can produce thousands of bricks per hour.

◦ Reliable Quality: Through technologies such as vibration – pressure separation, the strength of the products (some with strength ≥ 20Mpa) and precise dimensions are ensured, reducing defective products.

• Application Scenarios:

◦ Building Material Production: Mass – produce wall bricks, pavement bricks, etc. to supply construction projects, such as house building, road construction, and square paving.

◦ Solid Waste Treatment: In projects for treating solid wastes such as industrial waste residues and construction waste, convert them into brick products, achieving resource reuse and environmental protection goals.

• Some Brands and Their Features:

◦ Qunfeng Machinery: A well – known brand in the brick – making machine industry in China, whose products are sold to many countries. It has an advanced R & D center and numerous patents. Its intelligent brick – making machines have outstanding performance in precision control (such as the intelligent forming system with an accuracy of ± 0.5mm, higher than the EU CE standard) and green intelligent manufacturing (making bricks from recycled solid wastes, reducing costs and increasing efficiency).

◦ HESS: For example, the RH1400 concrete block forming machine is produced in accordance with German standards. By changing molds, it can produce various products such as PC stone – like imitation bricks and permeable bricks. The production system is balanced, ensuring high output and high quality.

2、Brick – making Machinery: The Core Force of the Modern Brick – making Industry

Brick – making machinery is a key equipment in the brick – making production process and is widely used in the building materials production field. It is of great significance for promoting the innovation of wall materials and realizing the comprehensive utilization of resources.

I. Basic Principles and Classification

Brick – making machinery operates based on the principle of material forming. Through processes such as mixing, pressing, and vibrating of raw materials (such as fly ash, coal gangue, tailings slag, clay, etc.), loose raw materials are made into brick blanks with a certain shape and strength.

According to the forming method, it can be divided into press – forming brick machines (using pressure to form raw materials, commonly used in the production of standard bricks, permeable bricks, etc.) and vibration – forming brick machines (relying on vibration to compact raw materials, mostly used in the production of large – volume brick types such as hollow bricks); according to the degree of automation, there are semi – automatic brick machines (requiring more manual auxiliary operations, suitable for small – scale brick factories) and full – automatic brick machines (with continuous operation from raw material processing to brick blank output, high efficiency, and suitable for large – scale production).

II. Main Component Structures

(1) Raw Material Processing System

It includes a crusher (breaking large pieces of raw materials into appropriate particle sizes. For example, when processing clay, crushing is conducive to subsequent uniform mixing) and a mixer (realizing the full mixing of raw materials and additives, etc., to ensure the uniformity of brick blank quality. For example, in the production of fly – ash bricks, fly ash, cement, admixtures, etc. need to be uniformly mixed), providing qualified raw materials for brick – making.

(2) Forming System

It is the core part. The forming system of the press – forming brick machine includes a pressure head, a mold, a worktable, etc. Pressure is generated through hydraulic or mechanical transmission to form raw materials in the mold; the vibration – forming brick machine relies on a vibration table, a mold, etc., and uses vibration to compact and form raw materials. Different molds can produce various brick types such as standard bricks, perforated bricks, and slope – protection bricks.

(3) Control System

Full – automatic brick machines are mostly equipped with a PLC control system, which can accurately set and regulate parameters such as forming pressure, vibration frequency, and production cycle to realize automated production. It can also monitor the operation status of the equipment in real – time, perform fault early warning and diagnosis, ensure stable production, and improve product precision and consistency.

III. Advantages and Functions

(1) Efficient Production

Full – automatic brick – making machinery can operate continuously, greatly improving the brick – making efficiency. For example, a large – scale full – automatic brick machine can produce thousands of standard bricks per hour, meeting the demand for bricks in large – scale construction and helping to promote the rapid progress of construction projects.

(2) Energy Conservation and Environmental Protection

It can effectively utilize waste materials such as industrial waste residue and construction waste. For example, using fly ash and coal gangue to make bricks not only reduces the land occupation and environmental pollution caused by waste residue accumulation but also reduces the dependence on natural clay resources, conforming to the development requirements of circular economy and green buildings and helping to achieve the “dual – carbon” goals.

(3) Diverse Products

It can produce brick products with different functions and specifications, such as standard bricks, hollow bricks, permeable bricks, and slope – protection bricks. Permeable bricks are used in urban roads to improve rainwater infiltration; slope – protection bricks are used in river courses and slope protection, having both ecological and structural functions, enriching the supply of the building materials market, and being suitable for various construction scenarios.

IV. Application and Development Trends

It is widely used in fields such as construction and municipal administration, providing basic materials for building walls, road paving, garden landscapes, etc. With the development of science and technology, brick – making machinery is developing towards being more intelligent (such as introducing AI to optimize production parameters and realize remote operation and maintenance), more environmentally friendly (reducing energy consumption and expanding the types of waste residue utilization), and more precise (improving the dimensional accuracy of brick blanks and the stability of mechanical properties). It continuously promotes the upgrading of the brick – making industry, injects new vitality into the green building materials industry, and will play a more crucial role in building a resource – saving and environment – friendly urban and rural construction system, helping to realize the sustainable development of the construction industry.
