Qt4-28concrete Block Making Machine Semi-Automatic Block Machines in Zambia

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.
