The concrete block making machine-model ZFM series is a kind of mould vibration machine, consisting of key forming unit, pallet, supplier, roller chain conveyor, mechanical, hydraulic and electrical system, as well as the programmable controller could automatically control hydraulic station. Center microprocessor and the whole production process. This series machine can be used in large fields. It is not only producing cement blocks, but also producing blocks form calash, cinder, gangue, volcanic ash, pumice stone as well as clay and ceramics. This series machine could produce different blocks of various dimensions. By simply changing the mould, different kind of construction blocks interlock paving blocks and blocks in other applications could be produced. Putting certain amount of pigment into material while mixing the color blocks could be produced. The QT series block-machine can be used for making blocks, not only from concrete but also from industrial waste coal cinder, volcanic ash, gangue and coal ash. The machine can produce different kinds of blocks, such as wall blocks, paving blocks and cavity blocks by just changing its mould. The machine is characterized by manual feeding, vertically vibrating pressure forming and mechanical stripping, and makes the blocks compact, strong and accurate.
