Working process for QT3-20 block Machine

Who is the QT3-20 colored paver block machine suitable for?

QT3-20 paver block making machine is a good choice if you:

  • Want to start a small paver block business.
  • Mainly produce colored or decorative paving blocks.
  • Have limited factory space.
  • Want to test the local market before investing in a larger plant.
  • Need several different molds for different products.
  • Do not need the production capacity of a large automatic block plant.

If your main products are standard hollow blocks and your required output is higher, QT4-25 or QT4-26 may be a better choice.

FAQs about QT3-20 Semi Automatic Colored Paver Block Machine

What is QT3-20 block making machine?

The QT3-20 is a semi-automatic, compact hydraulic block-making machine and an entry-level machine that offers excellent value for money for producing colored paving bricks. It is equipped with a 16 MPa hydraulic system and a vibration force of 55 kN, with a vibration frequency of 4,500 revolutions per minute, and is specifically designed for the production of high-density colored paving bricks, decorative bricks, and standard blocks.

It’s perfect for the job. The QT3-20 is specially calibrated for the production of colored bricks and is the smallest paver block production line capable of producing them. By combining high-frequency vibration with hydraulic compression, it tightly compacts the pigmented surface layer to the underlying concrete layer. The resulting colored bricks have a smooth surface, uniform color, and excellent wear resistance, making them ideal for municipal and garden paving projects.

Yes. The QT3-20 can produce up to 540 hollow bricks or 1,800 solid bricks per hour. By simply replacing the corresponding molds, you can easily switch between producing different sizes of hollow and solid bricks.

The QT3-20 mini colored brick production line typically requires 3 to 4 workers. One person is responsible for operating the main machine controls and laying the surface material, one person is responsible for mixing the base material and colored surface material, and 1 to 2 people are responsible for pushing the pressed, wet bricks to the curing area for stacking.

The dimensions of the QT3-20 block machine is 5990 × 4260 × 2620 mm. Including the two mixers, conveyor belts, and access aisles, a workshop shed of 150 to 200 square meters will suffice. Additionally, an open-air storage area of 300 to 500 square meters is required for curing and storing finished colored bricks.

Sure. During the initial stages of operating the QT3-20 colored paver block production line, you can load materials manually and transport them using a handcart. Once your business grows and you have sufficient funds, you can install auxiliary equipment such as an automatic batching machine and an automatic stacking machine at any time to gradually increase the automation level of your production line.

The QT3-20 is a compact, semi-automatic machine that is very affordable overall. The exact cost depends on how many sets of colored brick molds you choose and whether you want to include a second colored concrete mixer. You can send us the designs of the colored bricks you wish to produce, and the Furein Block team will provide you with a detailed quote for the minimum production line configuration.
