QT18-20 Block Making Machine

The QT18-20 block machine is the largest capacity machine in the world. You can make different designs of concrete blocks, bricks, paving stone and curbstone by changing moulds only. The block making machine QT18-20(18 stands for the production quantity of 18 blocks "400x200x200mm" per mold, 20 stands for the cycle time of 20 seconds) has the production output of 25,920 blocks (400x200x200mm) or 360 cubic meters for one day (8 working hours). As the molds are changeable, the block making machine is able to produce different types of blocks/bricks.
