1. High‑capacity 8 hollow blocks per cycle, capable for large‑volume construction orders
Ordinary block machines produce limited hollow blocks each cycle. When facing bulk procurement orders from real‑estate and infrastructure projects, insufficient output will extend delivery time or even cost you important clients. QT8‑15B is specially designed for large‑scale hollow‑block manufacturing. One single stroke forms 8 pcs standard 390×190×190 mm hollow blocks within 20‑25 seconds. It can steadily deliver 9200‑11500 hollow blocks for each 8‑hour shift. With unchanged workshop space, mixer and manpower, your daily hollow‑block output is greatly improved. For large construction supply contracts, the machine supports continuous shift‑operation to shorten lead‑time. You can take on bigger‑volume orders without purchasing extra main hosts, amortize equipment depreciation and accelerate your return‑on‑investment.
2. Table‑mold resonance plus dual‑direction compression, neat dense hollow blocks and less material waste
Hollow‑block production often suffers defective products such as offset cavities, uneven wall‑thickness, loose texture and chipped corners. Defective blocks waste cement and aggregates and may trigger customer returns, damaging your business reputation. QT8‑15B combines table‑mold resonance and upper‑lower bidirectional compression. 695 KN strong exciting force with adjustable vibration frequency penetrates every corner of mould cavity. Hollow cavities are sharply formed with even wall‑thickness. Finished hollow blocks reach qualified compression strength. Fresh green blocks can be stacked directly without easy cracking or breakage, keeping reject ratio low. Reliable hollow‑block quality meets overseas construction‑project acceptance standards, helping you secure long‑term supply contracts and reduce material loss caused by defective bricks.
3. Full‑process PLC automatic control, lower skill requirement and save long‑term labor expenditure
Traditional semi‑auto hollow‑block lines need many skilled workers for pallet feeding, material distributing, block discharging and stacking. Rising labor cost cuts profit, and staff turnover may interrupt your hollow‑block production schedule. QT8‑15B is equipped with PLC color touch‑screen intelligent control system, completing full‑cycle automatic pallet feeding, forced feeding, vibration‑compression molding, block ejection and automatic stacking. Auto, semi‑auto and manual modes are optional. Operators can run the production after simple training without rich brick‑making experience. Only a small number of workers are required for the whole hollow‑block line. Labor expenditure is significantly reduced. Production will not be disrupted by staff changes and your hollow‑block orders stay on schedule.
4. Quick‑change wear‑resistant moulds, expand product portfolio beyond hollow blocks to diversify your order sources
If your machine only makes hollow blocks, your factory will face sharp order decline once local hollow‑block market demand drops. QT8‑15B allows fast mould replacement without major host modification. Centered on hollow‑block production, it can switch to produce perforated bricks, permeable pavers, grass‑planting slope blocks and interlocking blocks. You can undertake orders for building walls, municipal landscaping and slope‑protection projects, maximize machine utilization rate. No need to buy multiple main machines. You capture more business opportunities and mitigate market‑fluctuation risks. Moulds are made of quenched Cr12MoV wear‑resistant steel, resisting heavy impact and abrasion during hollow‑block mass production, extending mould service life and lowering mould‑replacement cost.
5. Wide raw‑material compatibility, utilize local solid waste to cut per‑block production cost
Strict raw‑material requirements force buyers to purchase expensive fresh aggregates. Long‑distance transportation further raises unit cost of each hollow block and squeezes profit margin. QT8‑15B hollow‑block line features broad raw‑material adaptability. Besides normal cement and aggregates, high proportion of fly ash, steel slag, tailings sand, crushed construction waste, gangue and other industrial residues can be used for hollow‑block production. You can source cheap or even free local industrial waste nearby, reduce consumption of high‑cost cement and quality aggregates and save long‑haul logistics cost, directly improving profit margin of hollow blocks. Solid‑waste brick‑making meets environmental regulations in many countries, facilitating approval for new block plants and adapting to plant‑building conditions in various regions.
6. Heavy‑duty welded frame & premium core components, minimize unexpected downtime loss for shift‑based mass production
Hollow‑block machines run under long‑time heavy vibration. Thin frame and poor‑quality hydraulic or electric parts easily result in weld crack, oil leakage and electric faults. Unplanned shutdown delays hollow‑block orders and brings high spare‑part and production‑halt losses. QT8‑15B main frame is integrally submerged‑arc‑welded with thick‑section steel for high rigidity, resisting deformation and cracking under continuous heavy vibration of hollow‑block production. Key hydraulic, motor and electric parts adopt well‑known mature brands. Hydraulic system is equipped with heat dissipation and filtration units, suitable for two‑shift continuous mass‑production in hollow‑block factories. Unplanned downtime is largely reduced. Bulk hollow‑block orders can be delivered on‑time, safeguarding your overseas‑client reputation and cutting later‑stage repair time & money cost.
