Automatic Interlocking Brick and Hollow Block Machine

In the building materials manufacturing sector, fully automated brick-making equipment is gradually replacing traditional processes due to its high efficiency and environmental friendliness. Among these, interlocking brick machines and hollow brick machines account for a significant portion of municipal construction and housing building. Interlocking bricks, with their tight interlocking structure, dominate paving projects, while hollow bricks, with their lightweight and heat-insulating advantages, are the mainstream wall material.

Fully automatic interlocking brick machines

These machines primarily produce paving bricks, slope protection bricks, and other products with interlocking structures. Their forming process relies on the combined action of a hydraulic system and high-frequency vibration to ensure the precision of the interlocking between bricks.

The core advantage of this automatic interlocking brick making machine is its highly versatile molds; changing the molds allows for the production of interlocking bricks of different specifications, adapting to the needs of various scenarios such as plazas, parks, and sidewalks.

1. Common models and core parameters

Currently, the most representative fully automatic interlocking brick machines on the market are the "QT series" and "QS series," with the demand for small to medium capacity models being the strongest:

- QT4-15: Entry-level main model, molding cycle 15 seconds/plate, main unit power approximately 37.5kW, compatible pallet size 1100×700mm, can produce paving interlocking bricks of 200×100×60mm specifications, with a yield of 33 bricks per pallet.

- QS1500: Medium capacity model, molding cycle shortened to 11-22 seconds/plate, vibration frequency adjustable from 0-75Hz, main unit power 84.9kW, equipment dimensions 3490×2780×3210mm, suitable for batch production in medium-sized building materials factories.

- H1000: Production line level equipment, a fully automated configuration, integrating batching, mixing, and palletizing systems, with higher molding precision, particularly suitable for large-scale municipal engineering supporting production.

2. Output performance

The output of the interlocking brick machine is highly matched to its model. Based on an 8-hour workday and 300 operating days per year: the QT4-15 model can produce 63,360 paving bricks per day, exceeding 380,000 per year; the QS1500 model, with its shorter molding cycle, can increase its annual output to over 500,000 bricks under the same conditions; the H1000 production line can achieve continuous production, exceeding 100,000 bricks per day, with an annual output of up to 3 million bricks.

3. Core equipment composition

The fully automatic interlocking brick machine adopts a modular design. Its core components include four major systems: a hydraulic system (oil pump, cylinder, proportional valve) providing stable pressing force; a vibration system, with a high-frequency vibration motor ensuring material compaction; an electrical control system, with a PLC controller and touchscreen for precise parameter setting; and a conveying system, including a feeding mechanism, material distribution device, and palletizing robot, requiring no manual intervention throughout the process. Some high-end models are also equipped with a quick mold change device, improving the efficiency of producing multiple specifications.

4. Price range

Prices vary significantly depending on configuration and production capacity: the basic QT4-15 unit costs between $8,500 and $11,500; the mid-to-high-end QS1500 model costs between $15,000 and $25,000; while the H1000 complete production line, due to its high integration, costs between $28,000 and $28,500. It is worth noting that customized molds can increase the price of a single unit by 5%-10%.

Fully automatic hollow brick machine

The automatic hollow block machine uses industrial waste such as fly ash and slag as main raw materials. The hollow bricks produced have advantages such as lightweight, sound insulation, and heat insulation, making them a core material for green buildings.

Its technological highlight lies in the precise control of the core rod system, ensuring uniform pore size in the bricks, reducing weight without compromising strength.

1. Common models and core parameters

Hollow brick making machines are mainly based on the "QT series," divided into three tiers according to capacity:

- QT6-15: The first choice for small and medium-sized factories, with a forming cycle of 15 seconds per tray, a main unit power of 44.8kW, capable of producing 390×190×190mm hollow blocks, with a yield of 8 blocks per tray.

- QTY8-15: The mainstream capacity model, with a forming area of 1000×600mm, an adjustable forming height of 32-200mm, a main unit weight of 13 tons, and suitable for producing hollow bricks of various specifications.

- QT10-15: The core model for large production lines, with a stronger hydraulic system pressure, shortening the forming cycle to about 10 seconds, and increasing the main unit power to 87.7kW, supporting continuous 24-hour production.

2. Output performance

Due to the large volume of each hollow brick, the output calculation method differs slightly from that of interlocking bricks. When producing 390×190×190mm hollow blocks, the QT6-15 model has a daily output of approximately 17,280 blocks, with an annual output exceeding 1 million blocks. The QTY8-15 model increases the daily output to 25,000 blocks, with an annual output reaching 1.5 million blocks. The QT10-15 production line can achieve a daily output of over 35,000 blocks, making it particularly suitable for centralized supply to real estate projects.

3. Core equipment composition

Compared to interlocking brick machines, the core difference of hollow brick machines lies in the core rod system—composed of multiple sets of wear-resistant core rods, which, through a precision guiding mechanism, ensure the accuracy of hole forming, which is crucial for the thermal insulation performance of hollow bricks.

The remaining systems are similar to those of interlocking brick machines, including a higher-strength main frame (to handle the pressure of hollow brick forming), a quantitative material distribution system (to avoid material waste), and a waste recycling device (to improve raw material utilization). Some high-end models are also equipped with a brick strength detection module.

4. Price range

The price of hollow brick machines increases with production capacity and automation level: A single QT6-15 unit costs $8,000-$12,000; the QTY8-15, with its more complete configuration, costs between $18,000-$21,000; the QT10-15 unit costs $22,000-$49,000, and with a complete production line (including raw material processing systems), the price can rise to over $80,000.

It is worth noting that equipment with complete environmental certifications will be about 15% more expensive than ordinary equipment, but is more favored in the European and American markets.
