  • Strong Structure and Easy Maintenance

The frame of concrete block moulding machine HFB521M is dragon gate style and it is made of super steel, carrying strong resistance to vibration and being dependable. Four vertical shafts is wear-resisting, which can guarantee the accurate position for the mold. And the consumption carriage can be reduced to save power and easy maintenance.

  • Superior Elevating system

The elevating system of  the building block making machine HFB521M is made up of cone-shape motor, JZQ250 speed reducer, elevating arm, sliding sleeve, hang pin, position pin and so on. When working, the motor drive speed reducer through V-shape triangle belt, so the lower mold  lifts by elevating arms beside speed reducer shaft and then drives upper mold  to lift in the way that lower mold  sliding sleeve pulls upper mold  sliding sleeve.

  • Updated Material Storing Device

It is made up of material releasing hopper and material storing hopper. Material releasing hopper is fixed on the top of machine frame by bolts while material storing hopper is fixed below releasing hopper by bolts. When material feeding happens, the material releasing handle can be pulled manually or by motor, which drops material into mold  box and finishes feeding.

  • Flexible Block Machine Production Line

Combine Mixer, Conveyor Belt, Block Machine, Block Conveyor, Mould and Trolley etc. for this HFB521M brick making production line, increasing the block making efficiency.

  • Achieve Scrutiny and Smart Controlling

The smart control panel is of fault diagnosis system. Warning signal is propitious to eliminate the fault and in hence making material feeding easily with high efficiency and accuracy.

  • High Quality Blocks Produced

This HFB521M semi-automatic concrete hollow block making machine can produce high density cement blocks, solid/hollow/cellular masonry products, paving stones with or without face mix, garden and landscaping products, slabs, edgers, kerbstones, grass blocks, slope blocks, interlocking blocks, etc. by changing the customized brick moulds.
