QTJ4-40 Hollow & Manual Concrete Block Making Machine

The QTJ4-40 block making machine is a specialized equipment for producing concrete blocks. It can utilize raw materials such as gravel, river sand, tailings, and coal gangue to manufacture a wide range of wall and pavement blocks by changing molds. Featuring a rational design and advanced technology, it adopts four vertical shaft guidance, upper mold push-pull, automatic material feeding, and gearbox-driven mold lifting. Equipped with a powerful vibration motor for vertical directional vibration, the machine produces dense, high-strength blocks with stable quality. Its simple operation and energy-saving natural curing process make it comparable in performance to larger machines.
