Vibrating screening equipment in the traditional sense relies on a certain frequency of motor vibration to allow granular objects to pass through the screen to achieve material classification. Since it is an open screening, the material screening process is very dusty. , the material screening process invisibly causes waste and loss, and leads to great pollution of the natural environment and working environment. At the same time, vibrating screening has great requirements on materials, such as specific gravity, viscosity, and chemical properties, which results in many materials with small specific gravity being unable to pass through the screen, and many materials with high mesh number screening requirements cannot be screened. Since the 1980s, Professor Liang Xuezeng, chairman of Henan Xinxiang Hualiang Screening Machinery Co., Ltd. and chief engineer of the company, has presided over the design of vibration motors, vibrating feeders, vibrating hoppers, horizontal vibrating conveyors, vertical vibrating conveyors, and linear vibrating conveyors. Vibrating screens, rotary vibrating screens, vibrating mills and other series of vibration machinery products are known as the father of Xinxiang vibration machinery.
Since 1984, Professor Liang Xuezeng has focused on developing screening equipment that can achieve rapid, environmentally friendly and accurate screening of materials. After 8 years of technical research, combined with aerodynamic theory and mechanical engineering theory, , developed China's first airflow sieving machine - HLQS-100, and applied for the first national patent for airflow sifting machine in 1992, filling the gap in China's lack of screening equipment for medium and high mesh materials. Currently, Already has 4 national utility model and invention patents on air flow screens.
Since entering the 21st century, after nearly 10 years of continuous improvement and improvement, it has become increasingly perfect and has formed a series of products that can adapt to the screening requirements of various difficult-to-screen materials of different fineness and different output. The objective effects of energy saving, high efficiency and environmental protection have been achieved. After nearly 30 years of development and three generations of technological research and innovation, air flow sifting machines have become increasingly mature and are widely used in dozens of industries such as chemicals, food, building materials, and coatings.
