QT4-15D block machine 1. It is a compact machine with electric and hydraulic system, each procedure action locks with each other to guarantee the machine operate safely, easily and dependablely. 2. Through mold-releasing oil cyclinder, the mold box was locked into the vibration table with high rigidity to reach the synchronous vibration, so that the concrete can be fluidified and exhausted in two or three seconds to ensure the high-density, especially suitable to produce the standard blocks, which can be piled up immediately so that the pallet investment can be saved directly. 3. The unique forcing charge system can make use of various kinds of industrial waster and material such as coal ash, cement, sand, stone, slag, and so on. The machine can severs several purposes and produce various specification standard bricks, concrete blocks, porous blocks, paving bricks etc. Main parameter: 4. overall demension:6800*1500*2700mm 5. rated pressure:16Mpa 6. main vibration form:platform vibration 7. vibration frequency:4600(r/min) 8. pallet size:950*570*40mm 9. molding cycle:15-25s 10. overall power:27.85KW Productivity : Size Quantity Cycle moulding Per hour Per day Hollow brick 460*200*100mm 4 15-20s 960pcs 9600pcs Porous brick 240*115*90mm 14 15-20s 3360pcs 33600pcs Standard brick 240*115*53mm 28 15-17s 6720pcs 67200pcs
