Small and medium brick factories are limited by narrow workshop space. Large automatic block making machines and multi-type concrete brick machines occupy huge areas, and reconstructing brick factories will bring high civil engineering costs and extra factory rent. Meanwhile, construction market orders cover a wide range of products including hollow blocks, standard solid bricks, interlocking pavers, permeable bricks, curb stones and slope protection bricks. Purchasing multiple sets of block making machines and different brick molds separately will cause heavy capital pressure. Small and medium brick manufacturers urgently need a compact QT4-15S table vibration automatic block making machine that requires no factory renovation, supports fast mold replacement and multi-product production. One single QT4-15S concrete block machine can mass-produce all standard concrete bricks for construction, municipal engineering and landscape projects.
QT4-15S block making machine supports ultra-fast mold replacement within 30 minutes without any modification on the QT4-15S main body. By switching different brick molds, manufacturers can mass produce hollow blocks, 240 standard solid bricks, 200×100 interlocking bricks, permeable pavement bricks, municipal curb stones and ecological slope protection bricks. One QT4-15S automatic block making machine can replace multiple special small brick machines, greatly cutting down procurement cost of multiple block making machines, factory space occupation cost and daily maintenance cost of multiple units. QT4-15S concrete block machine is the preferred multi-specification brick making equipment for small and medium automatic brick plants.
QT4-15S block making machine is equipped with PLC touch screen intelligent control system, supporting three operation modes: manual mode, single-cycle test mode and continuous mass production mode. The whole procedures including pallet feeding, material distribution, high-frequency table vibration compression, synchronous demoulding and pallet circulation run fully automatically. The molding cycle of QT4-15S block making machine is only 15~20 seconds per mold. When equipped with standard solid brick molds, the hourly output reaches 5082~5760 pieces. The complete QT4-15S block making production line only needs 1 to 2 operators per shift, who are only responsible for raw material replenishment, pallet supply and equipment inspection. Compared with old semi-automatic brick machines, QT4-15S concrete block machine reduces labor cost by 70% and greatly improves the production efficiency of concrete brick production lines.
QT4-15S table vibration block making machine can consume industrial solid waste such as fly ash and slag, with the maximum fly ash mixing ratio up to 70%, complying with GB8239 concrete block production standards. Using QT4-15S concrete brick machine with stone powder, tailings and industrial waste residue for brick making meets international and domestic environmental protection policies for comprehensive solid waste utilization. Brick factories can apply for local subsidies for solid waste recycling. Producing concrete bricks with QT4-15S block making machine greatly reduces the procurement proportion of sand, stone and cement raw materials, cutting comprehensive raw material cost by 20%-35%. Meanwhile, factories can avoid fines caused by fly ash and slag stacking and transportation. QT4-15S block making machine is an eco-friendly automatic concrete block production equipment.
QT4-15S block making machine adopts core table vibration forming technology. The vibration system generates excitation force of 50kN with vibration frequency ranging from 2800 to 5100 times per minute. The hydraulic system maintains stable rated pressure of 16MPa, matched with forced synchronous mold lifting structure for smooth demoulding without jamming. Green bricks produced by QT4-15S automatic brick machine feature high compactness, accurate size, excellent frost resistance and impermeability. The reject rate of bricks with edge missing and corner breakage is significantly lowered, and the acceptance rate of concrete blocks supplied to construction and municipal projects is greatly improved.
3. Standard Supporting Configuration of QT4-15S Block Making Machine
QT4-15S block making machine is standardly equipped with special pallets of 900×550mm, automatic feeding belt conveyor and closed-loop pallet circulation conveying line, forming a complete set of block making production line.
QT4-15S concrete brick machine adapts to conventional 380V industrial voltage with total rated power of 21.75kW. Original transformers of small and medium brick factories need no capacity expansion, lowering the equipment installation threshold.
QT4-15S block making machine is manufactured by Shandong Hongfa Industry & Trade Co., Ltd. The manufacturer holds ISO9001 international quality management system certification and National Contract-abiding & Creditworthy Enterprise qualification. Complete qualification documents and environmental assessment filing materials for block making machines can be provided to simplify factory establishment approval procedures for small and medium brick manufacturers.
4. Benefit Hook of QT4-15S Block Making Machine for Factory Investment
Procuring one single QT4-15S automatic block making machine cuts total equipment investment by 60%. No factory reconstruction is required, saving huge civil engineering expenses. One QT4-15S concrete brick machine realizes synchronous production of multi-specification blocks, pavement bricks and curb stones, eliminating the need to purchase multiple small brick machines and greatly reducing capital occupation on equipment.
QT4-15S block making machine owns high automation level. The labor demand per shift is reduced from 3-4 workers of old brick machines to only 1-2 workers, saving tens of thousands of labor costs for small and medium brick factories every year.
QT4-15S table vibration block making machine supports high-proportion fly ash solid waste brick making, lowering consumption of natural sand and stone and significantly reducing brick production cost. Factories can avoid environmental penalties and apply for policy subsidies on solid waste comprehensive utilization.
QT4-15S multi-functional block making machine covers concrete brick production for construction projects, municipal roads, landscape gardens and water conservancy slope protection. Brick factories can receive orders from multiple industries simultaneously, expand sales channels and double the output of concrete brick orders.
