The QMJ‑12A is an upgraded egg-layer mobile block machine independently developed by Hongfa Science and Technology Industry, specially optimized for medium-scale block production. Adopting the classic pallet-free egg-laying working principle, it completely abandons the traditional production mode relying on plastic, steel or wooden pallets. All finished interlocking pavers and hollow blocks are directly formed and naturally cured on flat ground, eliminating long-term repeated costs of pallet purchasing, replacement, cleaning, maintenance and storage. Equipped with a full hydraulic automatic walking and steering system, the machine can freely shift working positions during continuous operation. It requires no fixed production line, no complex factory infrastructure and no auxiliary conveying equipment, adapting perfectly to open-air yards, rural construction sites and simple temporary workshops. This flexible walking design greatly reduces factory investment and site restrictions, bringing ultra-low-threshold and high-flexibility production solutions for global medium-sized brick making projects.
Tailored for producing high-quality interlocking pavers and hollow blocks, the QMJ‑12A features an upgraded secondary hydraulic vibration and pressure molding system. Compared with ordinary small egg-layer machines, it delivers stronger and more uniform high-frequency vibration force, which can fully exhaust internal air bubbles of raw material mixtures and make the materials densely filled in the mold cavity. The double vibration and one-time pressure molding process ensures that the produced hollow blocks have solid texture, uniform density and strong compression resistance, meeting the load-bearing standards of building wall masonry. Meanwhile, the finished interlocking pavers have neat edges, high compactness and excellent wear resistance, perfectly applicable for municipal road paving, courtyard landscaping and outdoor pavement projects. With high-precision interchangeable molds, the machine maintains stable product specifications and low defective rate, realizing standardized batch production of core building materials.
Centering on the core production of interlocking pavers and hollow blocks, this QMJ‑12A pallet-free egg-layer machine supports fast mold replacement to expand production diversity. On the basis of mainstream pavement and wall building blocks, it can also produce standard solid bricks, perforated bricks and slope protection bricks to meet different engineering needs. The equipment has extremely wide raw material adaptability, which can make full use of local low-cost raw materials such as natural soil, clay, river sand and stone powder, and also recycle green resources including fly ash, slag and construction waste aggregates. It turns waste materials into valuable building products, conforming to the global green environmental protection and circular economy development trend. It effectively reduces customers’ raw material procurement and transportation costs, achieving low-cost and eco-friendly block production.
As an upgraded enhanced model of the QMJ series, the QMJ‑12A adopts an integral thickened steel welded frame and optimized anti-resonance structure, which effectively avoids vibration deformation and mechanical fatigue during long-term high-frequency operation. The whole machine weighs 5000kg, with stable body rigidity and excellent shock resistance, adapting to long-time high-intensity outdoor continuous production. Matching with a mature hydraulic circulation system, the working pressure is stable at 6‑8MPa, with smooth feeding, pressing, vibrating and walking linkage actions. The scientific molding cycle is 20‑30 seconds per mold, achieving balanced and efficient production while ensuring product quality. The upgraded core hydraulic accessories have low failure rate and strong durability, greatly extending the overall service life of the equipment.
The QMJ‑12A adopts an integrated electromechanical-hydraulic control system and ergonomic seat lever operation design, with intuitive and simple operation logic without complex professional debugging. The whole production process only requires 1‑2 workers to complete feeding and auxiliary work, and novice operators can master the operation skillfully through simple training, saving long-term labor costs. Benefiting from the pallet-free design, the machine has no daily consumable loss, with low power consumption and simple daily maintenance. Routine inspection, lubrication and cleaning can be completed quickly without professional after-sales operation. It features low investment threshold, low operating cost and high return on investment, which is the ideal pallet-free egg-layer block making equipment for medium-scale construction and brick factory projects worldwide. All production data are theoretical values, subject to actual machine configuration, raw material ratio and operating environment.
