The QT8-15 automatic concrete brick making machine is a medium-capacity paver brick machine with a fully hydraulic drive design, officially designated QT8-15 Fully Automatic Hydraulic Concrete Brick Making Machine. It is a high-performance hollow block molding machine tailor-made for medium and large brick plants with mass production requirements.
Unlike small semi-automatic block machines, this fully hydraulic automatic brick machine adopts a high-pressure hydraulic system and heavy-duty table vibration forming unit as its core molding assembly, which is the core guarantee of stable high output and premium finished brick quality.The hydraulic system operates at a stable rated pressure of 21 MPa, paired with adjustable vibration frequency from 47 Hz to 75 Hz and strong exciting force. Synchronized pressing and vibration thoroughly compact various concrete raw materials within a 12–25 second molding cycle.
It has a total installed power of 42.9 kW and an overall machine weight of 13,800 kg. Its thickened one-piece steel frame withstands long-term high-intensity vibration without deformation, greatly prolonging the equipment’s overall service life.The effective forming area supports finished product heights from 50 mm to 200 mm, covering nearly all standard sizes of construction bricks for global municipal and residential building projects.
One outstanding competitive advantage of our QT8-15 brick machine lies in its excellent multi-mold and multi-product compatibility, making it versatile cement block production equipment for brick manufacturers worldwide.As a professional hollow block molding machine, it can form standard hollow blocks, eight-hole perforated bricks and solid standard bricks with matched molds. It also manufactures interlocking pavers, curb stones, grass planting bricks and slope protection blocks to fulfill various infrastructure orders.
Fitted with a standard 1100×680×30 mm pallet, the machine can produce 7 standard hollow blocks or 40 pieces of 240×115×53 mm solid standard bricks per single molding stroke. This delivers much higher single-cycle output compared with small block machines.Customers may optionally install an independent colored surface feeding unit to produce colored decorative paving bricks. This allows them to expand product lines and lift profit margins without buying an extra concrete brick making machine.
The feeding system features a large 0.7 m³ storage hopper and reciprocating equalizing spreader. It prevents uneven material buildup and cuts downtime caused by frequent refilling, supporting stable round-the-clock continuous production.
This medium-capacity paver brick machine boasts extremely broad raw material adaptability. It effectively lowers raw material costs for plant operators and complies with global environmental regulations as eco-friendly cement block production equipment.Rather than relying on costly pure cement, the QT8-15 brick machine enables users to blend cement with locally available river sand, crushed stone, fly ash, industrial slag and recycled construction waste aggregates as primary raw materials. The maximum mixing ratio of industrial solid waste can reach 70%, drastically reducing spending on cement procurement and long-distance raw material transportation.The entire production process adopts non-firing technology with no coal combustion or high-temperature kilns, producing zero harmful gas emissions. This allows brick factories to smoothly pass local environmental assessments and qualify for more municipal engineering tenders that require green production certifications.Finished blocks pressed by this fully-automatic hydraulic brick machine feature dense internal texture and a compressive strength exceeding 15 MPa, alongside excellent frost resistance, water impermeability and thermal insulation. They can be delivered directly to high-standard construction projects without secondary processing.
The intelligent unmanned operation system is another core highlight of the QT8-15 fully-automatic hydraulic concrete brick making machine, thoroughly addressing the high labor cost challenges faced by overseas brick plants.Fitted with an industrial PLC controller and an intuitive touch screen HMI (human-machine interface), the machine offers three switchable operation modes: manual single-action mode, single-cycle automatic mode and continuous fully-automatic production mode, catering to both small-batch trial runs and large-scale mass production schedules.The full production workflow — pallet feeding, forced material distribution, hydraulic vibration pressing, synchronous demoulding and finished block conveying — forms a closed automatic circulation. Only one or two auxiliary workers are required to stack pallets and collect finished bricks, slashing long-term labor expenses significantly.A built-in intelligent fault self-diagnosis module and safety interlock circuits automatically detect abnormal pressure, vibration faults and pallet deviation. The system cuts off power and hydraulic supply in real time to avoid equipment collision damage, reducing unplanned maintenance losses of this hollow block molding machine.All operating parameters such as vibration duration, hydraulic pressure and feeding speed can be saved and recalled with one tap on the touch screen, making frequent switches between different brick specifications extremely convenient.
All core wear parts and functional components of the QT8-15 concrete brick making machine are equipped with well-known domestic and imported brand accessories, which drastically cuts daily failure rates and users’ maintenance costs.The hydraulic station is separated independently from the main vibrating host to prevent dust and vibration from corroding hydraulic valves and oil cylinders, maintaining steady pressure output for years on end.Its four-column vertical guide structure paired with a three-layer composite vibration damping buffer design guarantees smooth, balanced mold lifting in every cycle. This ensures uniform thickness and dimensions for every brick with no uneven compression defects.
The manufacturer supplies complete categorized maintenance operation manuals covering daily lubrication, weekly fastener tightening, monthly component inspection and annual full-machine overhauls, together with a detailed fault troubleshooting table. Local staff can resolve common malfunctions without waiting for professional after-sales engineers, effectively cutting production downtime.Furthermore, this medium-capacity paver brick machine features a modular split assembly design. All functional units can be disassembled individually to fit standard shipping containers, reducing sea freight costs and simplifying on-site installation and commissioning overseas.
As a cost-effective medium-sized hollow block molding machine, the QT8-15 fully-automatic hydraulic brick machine achieves an ideal balance between high production capacity and affordable purchase costs. It is the top cement block production equipment for investors expanding medium and large-scale brick production lines across Africa, the Middle East, Southeast Asia and South America.
Unlike pricey large fully-automatic brick machines, the QT8-15 concrete brick making machine carries a lower initial investment threshold. Under stable operation, its hourly output of paving blocks reaches 90 to 120 cubic meters, significantly shortening the factory’s investment payback period.We offer full after-sales support including free operational training, a one-year full-machine warranty and lifelong spare parts supply services, so global purchasers have no concerns over post-sales equipment maintenance.
Whether you are a new investor building a brick plant from scratch or an existing manufacturer upgrading outdated semi-automatic equipment, the QT8-15 brick machine — as a mature fully-automatic hydraulic brick machine — delivers stable high output, low overall operating costs and consistent long-term profits for your building materials business.
