Development Trends of New Building Materials: Qunfeng Fully Automatic Block Production Line for Construction, Municipal Engineering, Landscaping, And Other Fields

As an eco-friendly building material and a key component of new walling materials, hollow concrete blocks are lightweight, fire-resistant, sound-insulating, and thermally insulating; they also offer impermeability and durability, while being pollution-free and energy-efficient. Driven by national policies vigorously promoting new building materials, the market demand for hollow bricks continues to rise. The fully automatic block production line launched by Qunfeng Machinery enables the efficient production of hollow bricks in various specifications; the product varieties and strength grades meet diverse construction design requirements, helping customers capture a share of the green building materials market.

Hollow blocks are characterized by a high void-to-total-area ratio, making them widely used in various construction applications. Currently, the market primarily offers hollow blocks made of cement concrete, lightweight aggregate, and industrial waste residue. Driven by green building and energy-saving policies, hollow bricks have become a primary material for building walls. Qunfeng Machinery’s hollow brick production line was developed specifically to address this trend; it utilizes various types of industrial solid waste to manufacture high-quality hollow bricks, thereby enabling resource recycling. A representative from a new building materials company in Jiangsu expressed deep appreciation for this shift: “In the past, disposing of steel slag and furnace slag incurred significant costs; now, using Qunfeng’s production line, these waste materials are transformed into sought-after hollow bricks—truly turning waste into treasure.”

The Qunfeng QS series fully automatic block production line manufactures products suitable for a wide range of applications, including load-bearing and non-load-bearing walls, road slope protection, plaza paving, hydraulic retaining walls, and landscape architecture. With an annual production capacity of up to 95 standard hollow blocks per pallet, the line delivers highly efficient, stable output and an ultra-short molding cycle, ranking among the highest-producing lines in the industry.

Equipped with Qunfeng’s patented servo-vibration system, the machine achieves ultra-high density and superior strength in the finished products through lightning-fast variable-frequency amplitude modulation and intelligent matching of material parameters. A customer from Quanzhou, Fujian, reported: “The vibration performance of this Qunfeng production line is truly outstanding; the resulting blocks feature smooth surfaces and high strength, passing site inspections with ease. We subsequently ordered additional production lines.”

Suitable raw materials include sand and gravel, crushed stone, fly ash, furnace slag, steel slag, coal gangue, ceramsite, perlite, and various types of mine tailings. By mixing one or more of these materials with cement, admixtures, and water, manufacturers can produce a diverse range of high-quality products, such as hollow bricks, slope protection bricks, paving stones, and curbstones. A building materials company in Zhejiang specifically noted: “Mold changes on this line are very quick; in our daily operations, we produce standard blocks while also fulfilling orders for paving stones and curbstones, making it very convenient to switch between products flexibly.”

Hollow brick products come in a wide variety and can be classified according to different criteria. Based on function, they are categorized into standard, decorative, thermal-insulating, and sound-absorbing blocks; based on structural form, into closed-bottom, open-bottom, and slotted blocks; based on void shape, into square-hole and round-hole blocks; based on void arrangement, into single-row, double-row, and multi-row hole blocks; and based on aggregate type, into ordinary concrete small hollow blocks and lightweight aggregate small hollow blocks. As a high-end, intelligently configured model, the Qunfeng “QS” series block-making equipment incorporates cutting-edge servo vibration and control technologies. Utilizing precise computer-controlled mix proportioning, the system not only ensures high product strength and dimensional accuracy but also enables flexible switching between different block types and specifications on the same production line through rapid mold changes or parameter adjustments.

This production line integrates mixing, molding, palletizing, and curing systems; it is widely used by manufacturers of non-fired blocks ranging from small to large scale and has become an ideal choice for new wall material enterprises seeking to boost production and enhance efficiency. Many customers have offered positive feedback after long-term use; the production director of a major building materials group in Hebei stated: “Since the equipment went into operation, it has run stably with a very low failure rate. The after-sales team is always responsive, and the overall operating cost is significantly lower than that of imported equipment.” Thanks to its high production efficiency, versatility in product manufacturing, and reliable performance, the Qunfeng block production line is earning the trust of an increasing number of users.
