I define fired brick production line automation as the coordinated use of material-handling equipment, forming machines, dryers, kilns, sensors, and industrial control software to convert prepared clay or other suitable raw materials into consistent fired bricks. In a typical automated line, a PLC or industrial control system manages recipes, machine sequences, temperature zones, conveying, alarms, and production records. The main process is raw material preparation, batching and mixing, extrusion or pressing, cutting and stacking, controlled drying, kiln firing, cooling, and finished-product handling.

The practical value is not simply reducing manual labor. I use automation to improve process repeatability, protect equipment, reduce handling damage, and give operators clearer information for adjustments. Because brick materials, product dimensions, fuel systems, and local operating conditions differ, the correct solution must be engineered around the required output and firing process rather than selected from a standard equipment list.
The process begins with clay, shale, coal gangue, fly ash, or another approved brick-making material being delivered to storage or feeding equipment. Automatic feeders, conveyors, box feeders, crushers, roller mills, and screens help control the movement and preparation of the material. I normally consider moisture variation and particle-size distribution at this stage because both factors influence forming stability and drying behavior.
A batching system can combine different materials according to a defined recipe. Load cells, level sensors, and feeder speed controls may be used to improve dosing consistency, although the final accuracy depends on equipment calibration and material flowability. Magnetic separators or screening equipment can also be included where the raw material requires protection against unwanted metal or oversized particles.
After primary preparation, the material is mixed with water and, where required, additives. Intensive mixers and double-shaft mixers are commonly used to distribute moisture more evenly before forming. I treat moisture control as a process decision rather than only a machine setting, because the correct value depends on the material composition, forming method, and desired green-brick strength.
An automated line can monitor water addition through flow meters, valves, or recipe-based control. However, operators still need laboratory or production checks because sensor readings alone cannot describe every change in clay plasticity. A practical control strategy combines measured input, mixer operating time, visual inspection, and regular product testing.
For extruded bricks, a vacuum extruder removes part of the air from the prepared material and pushes a continuous column through a die. A multi-wire cutter then divides the column into individual green bricks, while automatic stackers or transfer systems arrange the products for drying. For pressed bricks, hydraulic or mechanical presses form the material in molds, followed by automatic unloading and transfer.
Automation coordinates extruder speed, cutter timing, conveyor speed, and stacking patterns. If these settings are not synchronized, the line may produce dimensional variation, broken corners, or unstable stacks. I recommend evaluating the required brick size range, hollow or solid design, changeover method, die availability, and acceptable manual intervention before selecting the forming section.
Green bricks contain significant moisture and must be dried gradually before entering the kiln. A tunnel dryer or chamber-based drying system uses controlled air temperature, humidity, circulation, and exhaust to remove moisture without creating excessive internal stress. Drying conditions vary by material and product geometry, so I avoid treating one fixed schedule as suitable for every project.
Many industrial brick processes use drying temperatures within a broad range that may approach approximately 100–200°C, but the actual profile should be established through trials and material analysis. Sensors can measure air temperature and humidity at different zones, while dampers, fans, and burners regulate the drying environment. The automation system should also provide alarms for abnormal temperature, fan failure, excessive humidity, and material congestion.
In a tunnel kiln, kiln cars carry the dried bricks through preheating, firing, and cooling zones. Burners, combustion fans, pressure controls, zone dampers, thermocouples, and exhaust systems work together to maintain the required thermal profile. Firing temperatures vary by raw material and product specification, but many fired-brick processes operate in an approximate range of 900–1,200°C; the appropriate target must be confirmed by process testing.
The control system adjusts fuel and air according to temperature feedback and configured operating limits. It may also monitor kiln pressure, fan status, gas or fuel conditions, car movement, and emergency shutdown signals. Cooling is equally important because uncontrolled cooling can increase cracking or thermal shock, particularly when product geometry and material composition make the bricks sensitive to temperature gradients.
A complete automated line may include raw material hoppers, box feeders, crushers, roller mills, screens, mixers, extruders or presses, wire cutters, green-brick stackers, dryer equipment, kiln cars, tunnel dryers, tunnel kilns, unloaders, conveyors, and finished-brick sorting systems. The exact configuration depends on the product, capacity, fuel source, plant layout, and degree of automation required. I evaluate each machine as part of a connected process rather than as an isolated purchase.
With competitive price and timely delivery, Yinglai Technology sincerely hope to be your supplier and partner.
Material transfer deserves particular attention because conveyors, tables, and stackers must support the required product flow without excessive impact. Wear parts such as dies, cutter wires, rollers, seals, and refractory components should be considered during the design stage. A line that is easy to maintain can often be more valuable than one with a higher nominal speed but difficult access to critical components.
The PLC acts as the central logic controller for sequential operations, interlocks, motor commands, valve signals, and safety conditions. The HMI gives operators access to recipes, temperature trends, alarm messages, manual controls, and production status. A supervisory system may collect data from multiple line sections and help managers review energy use, downtime, material flow, and process deviations.
I recommend separating normal process control from safety functions where the project requires it. Emergency stops, burner management, access-door interlocks, overload protection, and high-temperature protection should be designed according to applicable local requirements and the selected equipment architecture. Remote access can support troubleshooting, but it should be protected through appropriate network controls and customer approval.
Start with brick dimensions, solid or hollow design, target daily output, raw material composition, fuel type, and expected product quality. A line designed for standard solid bricks may not be directly suitable for thin-wall hollow blocks or highly dimension-sensitive products. I also ask buyers to identify future product changes because die replacement, mold changes, stack patterns, and software recipes affect long-term flexibility.
Check whether the supplier can integrate feeding, forming, drying, firing, conveying, and control systems into one operating concept. Separate machines may function correctly in isolation but still create bottlenecks when their capacities and timing do not match. Important review points include buffer capacity, transfer speed, machine synchronization, kiln-car movement, alarm handling, and the recovery procedure after a power or equipment interruption.
Fuel consumption depends on material moisture, kiln design, insulation, firing profile, product loading, and operating discipline, so I recommend requesting a basis of calculation rather than relying on a generic guarantee. The automation design should provide access to temperature trends, operating hours, alarms, and maintenance status. For example, recording motor running time in hours can help plan inspections, while tracking kiln-zone trends can help identify gradual process drift before it becomes a major quality problem.
One common mistake is specifying equipment capacity without confirming the actual raw material behavior. Clay with changing moisture or excessive oversized particles can create forming problems even when the extruder is correctly sized. Another mistake is focusing on maximum speed while overlooking dryer capacity, kiln loading, cooling time, and finished-product handling.
I also see projects where operators receive limited training on alarm interpretation and recipe changes. A clear operating procedure should explain startup, shutdown, manual intervention, safe recovery, lubrication, inspection points, and quality checks. It is also sensible to keep critical spare parts, maintenance drawings, electrical documentation, and recommended wear-part lists available before commissioning.
Where the buyer has reliable production data, the control system can be improved through trend analysis and structured parameter management. Changes should be introduced one at a time whenever possible, with records of moisture, forming pressure or vacuum, dryer conditions, kiln temperatures, fuel use, and reject rates. This evidence-based approach is more dependable than adjusting several process variables simultaneously.
At Yinglai Technology, I approach fired brick production line automation as an integrated machinery and process-engineering project. We can discuss raw material information, product drawings, target output, fuel conditions, plant dimensions, forming method, dryer and kiln configuration, and the required level of electrical automation. Based on those inputs, the equipment scope and control architecture can be developed around the buyer’s actual production objectives.
Our support can include process-flow planning, equipment matching, automation configuration, technical documentation, installation coordination, commissioning assistance, operator training, and after-sales communication. The final scope should be confirmed against the customer’s material tests, local regulations, utility conditions, and approved technical specifications. This approach helps buyers compare suppliers on integration capability and lifecycle support, not only on individual machine prices.
Fired brick production line automation works by coordinating material preparation, forming, controlled moisture removal, kiln firing, cooling, and finished-product handling through mechanical equipment and industrial control systems. The best solution is not defined by automation level alone; it is defined by how well the complete line matches the raw material, brick design, output target, thermal process, and operating team.
As a practical next step, prepare your raw material information, product dimensions, target capacity, fuel conditions, plant layout, and preferred automation scope. Share these details with Yinglai Technology so we can help structure a suitable process flow, identify key equipment, and clarify the control and service requirements. A technically aligned specification at the beginning gives buyers a stronger basis for budgeting, supplier comparison, installation planning, and long-term production stability.
