Introduction to Urban Waste Brick-Making Process and Equipment

Urban waste brick-making is an environmentally friendly and efficient method of resource recycling. By classifying and processing the combustible and non-combustible materials in urban waste and converting them into building bricks, it not only solves the waste disposal problem but also conserves building material resources. However, due to the complex composition of urban waste and the presence of numerous harmful substances, it poses significant challenges in processing. Therefore, advanced processes and technologies are required for treatment.

Urban Waste Brick-Making Process

Waste Classification:

Urban waste is divided into combustible materials (such as paper, plastics, wood, etc.) and non-combustible materials (such as inorganic substances, metals, glass, etc.).

Combustible materials are used for incineration to generate electricity or heat, and some of the ash residue can be used as raw materials for brick-making.

Non-combustible materials are directly used for brick-making, such as inorganic substances and some incineration ash residue.

Waste Pretreatment:

Non-combustible materials are crushed, screened, and impurities are removed to improve the uniformity and stability of the raw materials.

Combustible materials undergo incineration treatment, and the resulting ash residue is cooled, crushed, and screened before being used as an auxiliary material for brick-making.

Mixing and Forming:

The treated waste raw materials are mixed with water or other additives to form a homogeneous wet mixture.

The wet mixture is placed into a brick-making machine and pressed under high pressure to form a brick mold.

Drying and Firing:

The formed brick molds are placed in a drying equipment to remove excess moisture.

The dried brick molds are then placed in a kiln for high-temperature sintering to achieve a certain level of strength and durability.

Flue Gas Purification and Emission:

During incineration and firing, the flue gas produced must undergo purification treatment to remove harmful substances and ensure compliant emissions.

Urban Waste Brick-Making Machinery and Equipment

Waste Crusher:

Used for crushing urban waste to meet the particle size requirements for brick-making.

The crusher boasts powerful crushing capability and flexible mobility, enabling on-site recycling of construction waste.

Screening Equipment:

Used to screen the crushed waste, separating qualified raw materials and returning unqualified ones for further crushing.

Screening equipment improves raw material utilization and reduces the impact of impurities on brick quality.

Mixing Equipment:

Mixes the treated waste raw materials with water or other additives to form a uniform wet mixture.

Mixing equipment features efficient mixing capability and stable performance, ensuring the uniformity and stability of the wet mixture.

Brick-Making Machine:

Places the mixed wet mixture into the brick-making machine and presses it under high pressure to form a brick mold.

The brick-making machine is characterized by its compact structure, easy operation, and high production efficiency. It can produce bricks of different specifications and shapes based on various requirements.

Drying and Firing Equipment:

Drying equipment is used to dry the formed brick molds and remove excess moisture.

Firing equipment is used to sinter the dried brick molds at high temperatures to achieve a certain level of strength and durability.

Drying and firing equipment are efficient, energy-saving, and environmentally friendly, ensuring brick quality and production efficiency.

In summary, the urban waste brick-making process and equipment represent an environmentally friendly and efficient method of resource recycling. By processing urban waste with advanced processes and technologies, it not only solves the waste disposal problem but also conserves building material resources, achieving a win-win scenario in terms of economic and social benefits. With continuous technological advancements and policy support, the urban waste brick-making industry will embrace broader development prospects.
