Trends of New Building Materials: Qunfeng Automated Block Line Serving Construction, Municipal And Landscaping Sectors

Concrete hollow blocks, as a green and environmentally friendly building material, are an important component of new wall materials. They are lightweight, fireproof, soundproof, heat-insulating, impermeable, and durable, and are also pollution-free and energy-saving. Against the backdrop of the national policy of vigorously promoting new building materials, the market demand for hollow bricks continues to rise. Qunfeng Machinery’s fully automated block production line can efficiently produce hollow bricks of various specifications. The variety and strength grade of the bricks can meet various construction design requirements, helping customers seize the green building materials market.

Hollow blocks have a high porosity in their total area, making them widely used in various types of buildings. Currently, the main types on the market include cement concrete hollow blocks, lightweight aggregate hollow blocks, and industrial waste hollow blocks. Driven by green building and energy-saving policies, hollow blocks have become one of the main materials for building walls. Qunfeng Machinery’s hollow brick machine production line was developed specifically for this trend, and it can utilize various industrial solid wastes to produce high-quality hollow bricks, achieving resource recycling. The head of a new building materials company in Jiangsu Province said with deep feeling: “In the past, it cost a lot of money to process steel slag and furnace slag. Now, with Qunfeng’s production line, these waste materials have been turned into sought-after hollow bricks, truly turning waste into treasure.”

The QS series of fully automatic block production lines from Qunfeng produces blocks with a wide range of applications, covering construction fields such as load-bearing walls, non-load-bearing walls, road slope protection, plaza paving, hydraulic retaining walls, and landscaping. This production line boasts an impressive annual capacity, capable of producing up to 95 standard hollow blocks per board. With a stable and efficient hourly output and an extremely short molding cycle, it is one of the highest-output production lines in the industry. Equipped with the patented Qunfeng servo vibration system, it achieves ultra-high density and high-fidelity strength in its products through lightning-fast frequency conversion amplitude adjustment and intelligent matching of material parameters. A customer from Quanzhou, Fujian, commented: “The vibration effect of Qunfeng’s line is indeed outstanding. The blocks produced have a smooth surface and high strength, and they passed the site inspection smoothly. We later added more production lines.”

Applicable raw materials include sand, gravel, fly ash, slag, steel slag, coal gangue, ceramsite, perlite, and various tailings. By mixing one or more of these materials with cement, additives, and water, a variety of high-quality hollow bricks, slope protection bricks, paving bricks, curb stones, and other products can be produced. A building materials company in Zhejiang also specifically mentioned: “This production line allows for quick mold changes. We routinely produce standard building blocks as well as take orders for paving bricks and curb stones, making the switching very convenient.”

Hollow brick products come in a variety of types and can be classified according to different dimensions. By function, they can be divided into ordinary blocks, decorative blocks, thermal insulation blocks, and sound-absorbing blocks; by structural form, they can be divided into bottom-sealed blocks, open-bottomed blocks, and grooved blocks; by hole shape, they can be divided into square-hole blocks and round-hole blocks; by arrangement, they can be divided into single-row, double-row, and multi-row hole blocks; and by aggregate, they can be divided into ordinary concrete small hollow blocks and lightweight aggregate small hollow blocks. The “QS” series block equipment of Qunfeng, as a high-end intelligent configuration model, is integrated with the cutting-edge advanced intelligent servo vibration and control technology in the industry.It is precisely proportioned and combined by a computer, which not only ensures high strength and high precision of the products, but also enables flexible switching between different types and specifications of blocks on the same production line through rapid mold replacement or adjustment of equipment parameters.

This production line integrates mixing, molding, stacking, and curing systems, and has been widely used in large, medium, and small non-fired block manufacturers, becoming an ideal choice for new wall material enterprises to increase production and efficiency. Many customers have given positive feedback after long-term use. The production director of a large building materials group in Hebei said, “Since the equipment was put into production, it has been running stably with a very low failure rate. The after-sales team is available whenever needed, and the overall operating cost is much lower than that of imported equipment.” With its efficient production capacity, wide product adaptability, and reliable user experience, the Qunfeng block production line is winning the trust of more and more users.
