PC brick making machine is a specialized molding equipment for producing prefabricated concrete pavement products, widely used in various infrastructure projects such as municipal roads, garden landscapes, community construction, etc. It can produce various concrete building materials such as imitation stone bricks, permeable bricks, roadside stones, grass planting bricks, etc. The equipment manufacturing and overall testing are carried out in accordance with the industry standard JC/T920-2011 "Building Materials Industry Block Forming Machine". The quality inspection of finished products follows national general specifications such as GB/T2542-2019 and GB/T8239-2014. It is a commonly used equipment in the fields of green prefabricated building materials production and industrial solid waste resource utilization. Compared to conventional non burning brick making equipment, PC brick making machines are equipped with independent layered fabric structures, which can achieve the integration of bottom base aggregates and surface colored fabrics in layers. The surface texture of the produced products is close to natural stone, suitable for the production needs of various high standard paving projects.

        According to the industry's general classification standards, the PC brick making machines in the domestic market are mainly divided into three categories: small fixed type, rotary table type, and fully automatic assembly line type. Different structural models correspond to different production scenarios of different scales and can adapt to the differentiated production needs of enterprises. The entire equipment is composed of five modules: ingredient mixing, layered fabric, hydraulic vibration forming, pallet conveying, and intelligent electronic control. Each module is designed and manufactured according to general industrial standards, and operates smoothly. The operating parameters can be flexibly adjusted according to the production category and material characteristics. Most models are equipped with PLC electronic control systems, which can store multiple sets of production parameters, and with fast mold changing operations, can adapt to the production and processing of various specifications of concrete products, with a wide range of applicable scenarios.

        In terms of molding process, the mainstream PC brick making machines in the industry generally adopt a composite molding method of hydraulic static pressure combined with high-frequency vibration, which enhances the overall compactness of concrete bricks through the synergistic effect of mechanical pressure and vibration. Due to differences in model specifications and configurations, the operating parameters such as forming pressure, vibration frequency, and amplitude of the equipment have reasonable fluctuation ranges, and mainstream equipment parameters can all meet industry standards. The equipment molding cycle and installed power vary depending on the size of the random type. Small and medium-sized models are suitable for the power supply conditions of conventional industrial plants and can meet the daily operational needs of small and medium-sized production lines. At the level of raw material adaptation, this type of equipment is compatible with industrial solid waste such as construction waste, fly ash, stone powder, and tailings as production aggregates. The proportion of solid waste blending can be flexibly adjusted based on material characteristics and finished product quality standards. Regular calibration of the raw material measurement system can reduce proportioning errors and ensure the stability of the production process.

        The overall production process of PC brick making machine is standardized and clear, with orderly connection of each process and a high degree of process standardization. In the early stage of production, staff need to crush and screen raw materials such as sand and gravel, solid waste aggregates, etc., and screen out aggregates with compliant particle size for classification and storage. The equipment can automatically complete the measurement and feeding operations according to the preset ratio, mixing the bottom aggregate mixture and the surface colored fabric mixture separately. The mixing time can be flexibly adjusted according to the dryness and wetness of the materials and the formula ratio to ensure uniform mixing of the materials. The production stage relies on a double compartment layered fabric structure to complete the laying operation, and the brick forming is completed through vibration static pressure composite technology. The forming equipment automatically completes the demolding, and the bricks are transported to the curing area with pallets for static curing. The conventional maintenance modes in the industry are divided into two categories: room temperature maintenance and steam maintenance. Different maintenance methods correspond to different product strength growth cycles. After meeting the maintenance standards, surface refinement processing such as shot blasting, water grinding, and splitting can be carried out according to project requirements.

        There is no fixed standard for the actual production capacity of PC brick making machines, which may fluctuate due to multiple factors such as random configuration, personnel proficiency, material ratio, and equipment daily operation and maintenance status. The publicly available production capacity data in the industry can only be used as a reference. Under normal production conditions, small fixed models are suitable for small-scale and small batch production scenarios, with relatively limited daily output scale; The rotary table model has good coordination among various processes and its production capacity is at a medium level in the industry; The fully automatic assembly line model has a higher degree of automation in operation and is suitable for large-scale, large-scale, and normalized production scenarios. Production enterprises can adjust product specifications and categories by replacing specialized customized molds. The various concrete pavement products produced can be applied to public pavement scenarios such as urban sidewalks, garden trails, community roads, and non motorized vehicle lanes.

        Energy consumption and environmental performance are important reference directions for current equipment iteration and upgrading. The new generation PC brick making machine equipped with a variable frequency control system has smoother energy consumption fluctuations and better energy consumption control performance than traditional non variable frequency models. The noise generated by equipment operation meets the noise emission control standards of industrial plants. Enclosed structures are often used for dust generating processes such as batching and mixing, which can reduce dust overflow and improve the production environment. The entire production process does not require clay sintering, does not occupy natural clay resources, and can absorb a large amount of various industrial solid wastes. It conforms to the industry orientation of green building materials development and solid waste resource utilization, and is in line with the development trend of low-carbon production.
