Factory Direct · In Stock · Ready to Ship

<p><strong>QT4-15A Automatic Concrete Block Making Machine, 18.45 kW, 850×550×25mm Pallet, 40-50 kN Vibration Force</strong> — specified as a matched production line with JQ350 mixer, conveyor, host press, automatic stacker and trolley transport so station cycle times align and the press is never left waiting. Dual vibration combines bed mould vertical oscillation with upper mould compression for uniform block density across the pallet.</p> <ul> <li>Hollow, solid, paver and curbstone formats via mould change</li> <li>Line layout and full station list confirmed in quotation before production</li> </ul> <p>Block machinery is our single focus, so the mixer, press, pallets and handling equipment are engineered as one coordinated system rather than sourced separately.</p>
