The whole host frame of QT12-15F fully automatic block machine is integrally welded by 20cm×20cm thick square steel supplied by Laigang and Jigang, top domestic steel manufacturers. Compared with thin steel frames used by ordinary block equipment, this thickened structural design greatly enhances the overall rigidity, torsion resistance and anti-deformation capacity. Even under long-term continuous high-frequency vibration and heavy hydraulic stamping work, the frame will not bend, crack or deform permanently, effectively extending the whole service life of the main machine and maintaining stable molding precision for years of mass production.
The hydraulic system adopts original Rexroth hydraulic components imported from Germany, the globally recognized top hydraulic brand. The hydraulic oil circuit runs smoothly with tiny pressure fluctuation, low internal leakage and ultra-low failure rate, which can support 24-hour non-stop industrial production. All electrical control parts and touch screen human-machine interfaces are imported Siemens brand products with stable signal transmission, strong anti-interference performance and long service life. The machine also introduces mature European universal transmission shaft technology, which balances vibration force evenly during operation and avoids motor burnout caused by unbalanced vibration load.
The QT12-15F fully automatic fly ash brick making machine is equipped with a full platform synchronous vibration system with a maximum exciting force of 110KN and adjustable vibration frequency ranging from 2800 to 5100 cycles per minute. Frequency conversion vibration motors are adopted, so operators can adjust vibration parameters flexibly according to different raw material characteristics such as fly ash, slag and gravel. High-frequency vibration cooperates with standard 21Mpa hydraulic pressing force simultaneously during molding, making concrete raw materials fully compacted inside the mould. The produced blocks and pavers feature uniform internal density, smooth surface, no honeycomb holes or loose edges, and meet international building material strength standards.
A complete feeding, vibrating and pressing molding cycle only takes 15 to 25 seconds, which is far faster than many similar block machines on the market. Equipped with a large-size pallet of 1420×900mm, one mould can produce a large quantity of finished bricks per cycle. Under standard 8-hour continuous operation, the daily output reaches up to tens of thousands of blocks, perfectly matching large-scale brick factories and industrial solid waste recycling enterprises with high production demands.
The QT12-15F machine is equipped with a complete PLC intelligent automatic control system matched with a touch screen operation panel. All production procedures including automatic feeding, vibration pressing, demoulding, pallet feeding and green block conveying are set with standardized automatic programs. The system carries a built-in fault self-diagnosis module, which can automatically capture abnormal signals of vibration, hydraulic pressure and material supply, and pop up clear fault prompts on the screen. Ordinary workers with simple training can quickly judge and eliminate minor faults without professional electrical maintenance engineers on site all year round.
Different from traditional manual semi-automatic block machines, this full-automatic model supports remote control and remote diagnosis. Factory managers can view real-time production data, equipment running status and historical failure records remotely, realizing unattended centralized management of the production line. The complete logic control program reduces manual operation links by more than 60%, effectively cutting labor costs of brick production workshops.
The machine has extremely high tolerance for mixed raw materials. It can take fly ash, coal cinder, mineral slag, coal gangue, crushed stone, river sand, cement and expanded perlite as main production aggregates. Factories can make full use of local industrial waste residues to replace a large proportion of expensive cement and natural sandstone, drastically lowering overall raw material expenditure. This waste recycling production mode complies with global circular economy and environmental protection policies, and helps manufacturers apply for relevant environmental assessment certificates and industry subsidies.
A complete lifting and walking color feeding system is standard configuration of QT12-15F. It realizes separate layered feeding of surface color mortar and base concrete in one molding cycle. Without purchasing extra independent color mixing equipment, one machine can produce hollow blocks, solid standard bricks, perforated bricks, colorful interlocking pavers, garden landscape slabs, curb stones, grass planting blocks and slope protection blocks. Diversified finished products expand market business channels and bring multiple profit sources for manufacturers.
The optimized vibration matching structure realizes low-frequency feeding and high-frequency pressing molding, which effectively protects motors from overload damage and reduces comprehensive power consumption by 25% compared with peer equipment of the same specification. All motors adopt energy-saving frequency conversion design, which automatically adjust power output according to actual production load, avoiding idle power waste during waiting intervals. The integrated heat dissipation structure of vibration box and hydraulic station reduces extra cooling energy consumption, and the whole production line achieves obvious energy-saving effect under long-time continuous operation.
The complete QT12-15F production line includes JS750 twin-shaft mixer, PLD1200 batching machine, double-layer conveyor belt, automatic block stacker, pallet elevator and hydraulic pallet cart. All auxiliary machines coordinate automatically with the main block machine to realize unmanned full-process production from raw material batching to finished block stacking, no manual transfer of green bricks needed in the middle link. Optional 100-ton cement silo and supporting screw conveyor further realize automatic cement feeding without manual loading.
If customers purchase the full set equipment from No.1 to No.10, the whole production line needs three standard 40HQ containers for shipment; if only the core production set from No.5 to No.10 is selected, one 40HQ container is enough. Compact integrated structural design saves ocean freight space and reduces international logistics cost for overseas buyers. All parts are standardized packed to avoid collision damage during long-distance sea transportation.
The manufacturer provides one-year global warranty service for the QT12-15F block machine, counting from the date of complete installation and commissioning at the buyer’s factory. Within the warranty period, all standard spare parts damaged due to original manufacturing quality problems can be replaced free of charge. Professional English-speaking technical team provides lifelong online remote guidance for installation, debugging, mold replacement and daily fault troubleshooting, lowering the later operation risk and maintenance investment of overseas customers.
