The QTJ4-35B2 semi-automatic concrete cement block making machine, also simply referred to as the QTJ4-35B2 concrete block making machine or QTJ4-35B2 semi-automatic block machine, is an economical table-vibration block molding device tailor-made for small workshops and individual startups. As an entry-level concrete block machine, it perfectly fits family building material processing plants and rural small brick yards overseas. The machine can run independently, or form a simple production line when matched with belt conveyors and J350 mixers. The whole production workflow is straightforward with complete process diagrams provided, so new operators can master the entire brick-making procedure quickly. Boasting prominent strengths in core configuration, production capacity, raw material compatibility and easy maintenance, it is the top choice for low-cost entrepreneurship as a reliable semi-automatic concrete cement block machine.
Equipped with professional table vibration and upper pressing vibration structure, the machine has two 3KW lower vibration motors and one 1.5KW upper vibration motor, with a total power of 8.6kW and exciting force up to 40KN at a vibration frequency of 2800rpm. Each molding cycle only takes 35 seconds. The synchronous compression and vibration of upper and lower molds ensure even material filling, eliminating defects such as loose texture, delamination, missing corners and uneven thickness. The finished blocks meet standard requirements on strength and surface smoothness, greatly cutting waste loss. Under standard working conditions, its daily stable output ranges from 2,200 to 2,700 blocks, producing 3 to 6 blocks of various specifications per stroke. Custom molds can be quickly replaced to manufacture perforated bricks, solid bricks and hollow blocks, making it versatile for diverse small infrastructure orders.
This QTJ4-35B2 concrete block making machine does not rely on high-priced pure cement. It supports locally sourced river sand, sea sand, crushed stone, stone dust and brick residue, as well as industrial solid waste including fly ash, cinder, ceramsite and recycled construction waste aggregates. Both ordinary concrete and lightweight concrete can be processed. Clients do not need long-distance transportation of special aggregates; production can start with waste materials recycled locally. It complies with global environmental policies on solid waste recycling, effectively reducing expenses on raw material procurement and logistics, and boosting profit margins for small processing plants.
With overall dimensions of 150016602460mm, the machine occupies a tiny space and can be installed on flat ground without large standardized workshops. Its affordable purchase price eases the pressure of startup funds. Only a small number of workers are required for operation, and staff with zero mechanical experience can master the full procedures of feeding, material distribution, vibration and demoulding after short training. The manufacturer provides complete classified maintenance guides and fault troubleshooting tables. Local workers can resolve common malfunctions of positioning pins, vibrators and reducers without waiting for overseas after-sales engineers, minimizing unplanned production downtime.
The integrated channel steel frame consists of lifting, vibration, electric control and hopper modules. The lifting unit is fitted with brake motors, reducers and positioning pins, while the suspended upper and lower molds enable smooth demoulding. All connecting bolts and lubrication points are clearly arranged. Operators only need to add lubricant and fasten fittings per shift; vibrators just require simple maintenance every three weeks. Wear parts suffer low loss, and the whole machine resists deformation under long-term heavy-duty operation. Original spare parts are supplied long-term to keep later maintenance costs low.
The machine has low installation requirements, only needing flat solid ground and regular power supply. Supporting mixers and conveyors can be installed at a 90° side layout. The circuit is equipped with leakage protection devices, and motor rotation direction is adjustable to optimize vibration effects. The raw material mixing ratio is simple: concrete can be produced by mixing stones, stone dust and sand in fixed proportions with easy moisture control. Complete safety operation guidelines are attached. The whole machine must be grounded reliably; noise-proof gear is recommended during operation, and protective nets are installed on mixer feed inlets to prevent dangerous manual feeding.
Whether you are a first-time investor stepping into the building material industry or an existing small brick yard upgrading outdated semi-automatic equipment, this multi-functional concrete block machine delivers stable high-quality blocks, fully meeting the supply demands of rural housing construction, small municipal roads and wall projects across Africa, the Middle East, Southeast Asia and South America.
