QT5-15 Automatic Concrete Block Molding Machine

Product Description

<h2>Composite Forming in a 15 to 20 Second Cycle</h2><p>The QT5-15 molds blocks by combining high frequency vibration with hydraulic pressure. Vibration fluidises the mix so it flows into every corner of the mould, then the hydraulic unit applies a forming pressure of 25 MPa to lock the structure before demoulding. The two actions run as one stroke rather than as separate stages, and a forming cycle of 15 to 20 seconds sets the production rhythm of the line.</p><p>Blocks leave with even edges, stable strength and dimensional tolerance held tighter than the usual site requirement. Pallet size is fixed at 1,100 x 650 x 20 mm, so pallet handling equipment can be specified once and kept for the life of the line.</p><h2>Drive, Power and Frame Construction</h2><p>Total installed power is 37.4 kW, of which a dedicated 2.25 kW motor drives the feeding and distribution box. An excitation force of 58 kN is delivered into the mould, which is high enough to handle stiff, low slump mixes that older vibration-only machines struggle with.</p><p>The host is built around a heavy integral welded frame, stress relieved by aging treatment before machining. That matters more than it sounds: continuous high frequency vibration and pressing will distort a frame that was only bolted together, and once the frame moves, block height tolerance moves with it. Host weight is 6,900 kg and the host envelope is 9,450 x 3,300 x 2,700 mm.</p><h2>PLC Sequence and Operator Control</h2><p>A PLC programmable controller and an industrial touch screen handle the full sequence: raw material feeding, forced material distribution, vibration and pressing, demoulding and brick removal, then pallet recycling. Each step is coordinated with the next, so the machine keeps a steady cycle without an operator standing at the mould.</p><p>Parameters are entered once and stored as recipes. The screen shows live machine status, and the diagnostic function names the step that failed instead of showing only a fault number. For a plant running several block types per shift, that shortens the changeover between moulds.</p><h2>Building a Complete Block Line</h2><p>The QT5-15 connects directly with batching machines, mixers, belt conveyors and automatic stacking machines. A line assembled from these modules moves material without manual handling between stations, which cuts both labour cost and the physical workload on the crew.</p><p>Typical buyers are municipal building materials producers and solid waste resource recovery plants making non-fired units. Before sizing the line, agree on the pallet count and the curing area, because stacking capacity rather than moulding speed is usually what limits daily output.</p>
