This is a HERCULES series fully automatic hydraulic non-fired brick machine (typically corresponding to HCNCHA brand models), a mature, widely used, and eco-friendly brick-making device in the current building materials production sector. It is mainly used to press industrial solid wastes (such as fly ash and slag), sand, gravel, cement, and other raw materials into construction materials like non-fired bricks, hollow blocks, and permeable bricks.

I. Core Structure and Design Features

Visually, this brick machine adopts a heavy-duty steel structure frame with blue-and-yellow color blocking, featuring a compact and modular overall layout. It is primarily divided into three functional units:

1. Left-side Feeding and Material Distribution System: Equipped with a large-capacity hopper and a forced rotary material distributor, it can accurately and quickly deliver uniformly mixed raw materials into the mold cavity. The material distribution process is quiet and highly uniform, avoiding density variations in the bricks.

2. Central Pressing Main Unit: The core is an integrated hydraulic and vibration system—high-pressure oil cylinders controlled by an intelligent PLC provide pressing force (usually up to 15-20 MPa), which works with the high-frequency vibration (of the bottom vibration platform) to quickly compact and shape the raw materials under high pressure + high-frequency vibration, ensuring brick strength (up to MU15 or higher). A yellow safety protective net is installed outside the main unit, which not only ensures operational safety but also facilitates daily maintenance.

3. Right-side Finished Product Conveying Unit: After forming, the bricks can be demolded and transferred via automatic pallet-receiving and conveying mechanisms, achieving continuous production without manual intervention.

The entire device uses wear-resistant steel and a sealed dust-proof design. Key components (such as molds and oil cylinders) are made of high-hardness alloy materials, which effectively reduce wear and extend the equipment’s service life. It is also equipped with a circulating lubrication system to reduce the probability of mechanical failures.

II. Working Principle and Production Process

The core logic of this brick machine is “raw material proportioning → mixing → material distribution → high-pressure vibration forming → demolding and conveying”, with fully automated operation:

1. Raw Material Preparation: Industrial solid wastes (such as fly ash, slag, stone powder, and sand) are mixed with a small amount of cement (as a gelling material) in proportion, then water is added to stir into a semi-dry mixture (with a moisture content of about 10%-15%).

2. Material Distribution and Forming: The mixture enters the forced material distributor through the hopper and evenly fills the mold cavity. Then the hydraulic system drives the pressure head downward, which cooperates with the high-frequency vibration of the vibration platform (usually 50-60 Hz) to compact the raw materials in a short time, forming brick blanks with stable shape and strength.

3. Demolding and Discharging: After forming, the mold is lifted for demolding, and the finished bricks are conveyed to the drying area along with the pallets. No sintering is required; the bricks can leave the factory after natural curing or steam curing.

III. Equipment Advantages and Application Scenarios

As an eco-friendly building materials device, its core advantages are reflected in three aspects:

• Resource Utilization and Environmental Protection: It does not require clay or rely on sintering, and can absorb industrial wastes such as fly ash and slag (the annual absorption capacity of a single device can reach thousands of tons), reducing solid waste accumulation and carbon emissions, which aligns with the national policy orientation of “banning clay and restricting sintering”.

• High Efficiency and Versatility: The intelligent PLC control system supports one-button operation; the production cycle per mold only takes 15-20 seconds, and the daily output of standard bricks can reach 30,000 to 50,000 pieces. By replacing different molds, it can produce more than ten types of building materials (such as standard bricks, hollow blocks, permeable bricks, and slope protection bricks), adapting to multi-scenario needs like building walls, municipal roads, and landscape architecture.

• Economy and Stability: Compared with traditional sintered brick production lines, the investment cost is reduced by about 30%, and the operating energy consumption is only 1/5 of the sintering process. The device is equipped with a fault diagnosis system that can real-time monitor parameters such as pressure and vibration frequency, with a low maintenance rate, making it suitable for small and medium-sized building materials factories or solid waste treatment projects.

This brick machine is one of the typical devices for the “green transformation” of the current building materials industry. It not only solves the problem of resource utilization of industrial solid wastes but also provides low-cost, multi-category building materials for the market, and its application in urban-rural construction and infrastructure projects is becoming increasingly widespread.
