1. Main Machine Principle & Complete Production Composition
QTJ4‑35B2 semi‑automatic concrete hollow block making machine belongs to compact small‑scale block‑forming equipment, which can work as a standalone main unit, or cooperate with belt conveyor and concrete mixer to build a full small‑size block production line. The whole machine mainly consists of lifting system, dual‑vibration system and electrical control system. Its lifting system adopts brake motor, reducer, gear disc and lifting arm structure to realize stable parallel lifting movement of lower mould, ensuring flat demoulding and avoiding tile skew. For vibration performance, it is equipped with two 3KW bottom vibrators and one 1.5KW upper vibrator to realize double‑sided compound vibration. The vibration force can penetrate all areas inside mould cavity, so raw materials can be fully compacted to produce uniform‑quality hollow blocks, paving bricks and concrete solid bricks. Whether customers choose single‑machine trial production or complete assembly‑line layout, the core mechanical structure can keep stable long‑time running performance for small brick factories.
2. Complete Production Workflow & Flexible Capacity Matching
The complete production workflow covers raw material preparation, mixing, conveying, mould forming, demoulding and finished‑product curing till final inspection and delivery. Raw materials including cement, sand, gravel, fly ash and various industrial residues are fully blended inside the mixer, then transported to the host hopper by belt conveyor. After pallet positioning, feeding, segmented bottom vibration material distribution, upper‑die auxiliary vibration compaction and mould lifting, finished blocks are pushed out for outdoor curing and subsequent stack curing process, and qualified goods will pass inspection before delivery. This equipment supports two operation modes to satisfy different business plans: buyers with low‑volume demand can run the machine independently with simple manual assistance; for factories pursuing stable output, adding supporting mixers and conveyors can reach daily capacity of 2200‑2700 blocks per shift. Customers do not need to invest in over‑size production lines blindly, they can expand supporting facilities step‑by‑step according to actual order quantity and site space condition. Only 2‑3 operators are enough for whole‑line operation, which greatly controls overall labor input for individual investors and rural building‑material plants.
3. Dual‑vibration Performance For High‑quality Dense Finished Bricks
Adopting combined upper‑and‑bottom dual‑vibration design with total exciting force up to 40KN, QTJ4‑35B2 solves many common quality defects of entry‑level block machines such as loose brick interior, layered separation, corner chipping and surface cracking. Two bottom vibrators undertake main material compaction work while the 1.5KW upper vibrator applies auxiliary pressing vibration, making vibration energy evenly spread across the whole mould cavity. Under reasonable vibration time control of 6‑8 seconds bottom vibration plus extra 2‑5 seconds compound vibration, raw materials fill every corner of mould thoroughly. The finished hollow blocks, solid bricks and slope‑protection bricks own compact internal structure and high compressive strength, which can meet acceptance requirements of local construction, road paving and slope‑protection projects. The mechanical transmission structure is concise and reliable, reducing abnormal damage caused by long‑time continuous production, so brick factories can lower reject rate and cut waste of raw materials in mass‑volume production.
4 Powerful Raw‑material Compatibility, Multi‑mould For Diversified Product Manufacturing
This semi‑automatic block machine has outstanding adaptability for both ordinary concrete and lightweight concrete materials. Besides conventional river sand, crushed stone and manufactured sand, it can make full use of locally‑sourced low‑cost resources including fly ash, coal cinder, stone powder, shale, ceramsite and multiple kinds of industrial waste residues. Factories can replace part of cement and high‑priced natural aggregate with these waste materials, significantly decrease raw‑material purchasing cost and improve product profit margin, meanwhile complying with global solid‑waste recycling environmental standards. Supported by wear‑resistant manganese‑steel mould sets, the machine can produce multiple kinds of building products only by replacing moulds. Customers can produce hollow blocks for building walls, solid standard bricks, permeable paving bricks and slope‑protection blocks to cover housing construction, municipal road and river‑bank protection project orders. Custom‑made moulds for special local sizes are also available, helping brick plants handle diverse market demands without purchasing multiple separate host devices.
5 Simple Operation, Low Threshold & Cost‑effective Investment Return
Designed for small‑scale brick‑making entrepreneurs, QTJ4‑35B2 avoids complex expensive hydraulic systems, so the initial procurement investment stays at a friendly level for startup factories. The machine adopts manual switch control logic instead of complicated programming system. New operators can master the full set of moulding cycle procedures within 1‑2 days even without special technical background, which saves plenty of worker training expenses. Main moving parts apply mature mechanical transmission structure with low failure probability; routine daily work only contains lubrication treatment and bolt tightening, no complex high‑cost maintenance work required. It does not demand special reinforced factory foundation, flat hardened ground can support normal production. For investors who want to enter building‑material manufacturing market, this machine features small footprint, easy installation, simple operation, flexible collocation of auxiliary equipment and rich product possibilities, bringing stable and considerable investment return for small brick yards.
