Qt4-28 Semi Automatic Construction Equipment Cement Concrete Block Stone Machines Hollow Block Making Machine

By changing the moulds can make different size of hollow blocks, solid blocks, pavers and curbstones, with 63+ mould types available (28 hollow/solid + 28 paver + 7 curbstone).

Semi-automatic with automatic feeding and automatic moulding. The same material volume is fed into the moulds every cycle, so block density and strength stay uniform across the whole production batch.

4 blocks per mould, capacity up to 4608 pcs per 8 hour shift for 400x200x200mm hollow block, cycle time only 25-40 seconds.

50KN platform vibration with 2800-4500 r/min frequency and 6 motor circuits, for dense and high-strength blocks.

Dedicated PLC control cabinet automatically runs all 6 motor circuits, with real-time parameter display, manual override for each circuit and emergency stop button.

JQ500 mixer (800L input / 500L output, 43% larger than JQ350) with 8M belt conveyor keeps material supply in step with the fast cycle. Only 2-3 workers run the complete line.

Heavy-duty ZQ reducer with bearing-mounted rotary parts, thickened square steel frame and wear-resistant sleeve liners on the 4 guide columns, for long service life and low failure rate.

Can use fly ash, cinder, slag and other industrial waste materials as partial aggregate to reduce raw material cost.

1 standard 400x200x200mm hollow block mould included. 100% pre-shipment production test video sent before shipment. 2 years warranty on core mechanical and PLC components.

Manufacturer since 1985, CE and ISO 9001 certified, MOQ 1 set, English manual and 24-hour technical support.
