In the powder processing links of chemical, pharmaceutical, food, building materials and other industries, the precise sieving of ultrafine powder has always been an industry pain point. Traditional vibrating sieving equipment relies on gravitational potential energy for operation. When dealing with fine powders in the range of 80-500 meshes, it often suffers from agglomeration and screen clogging, insufficient sieving precision, dust emission and other problems. These issues not only affect the stability of product quality, but also may cause material waste and environmental impacts, making it difficult to meet the demands of modern production for refinement, high efficiency and environmental protection.
The YK-QLS Airflow Sieve developed by Yika (Shanghai) Technology Co., Ltd. has pioneered a new path for powder sieving. With aerodynamics as its core principle, it subverts the operational logic of traditional sieving. Different from traditional vibrating sieves, the YK-QLS Airflow Sieve adopts a closed structure. Taking high-speed airflow as the carrier, it ejects fully dispersed powder particles to the screen with sufficient kinetic energy to achieve precise classification. Utilizing the characteristics of light weight and easy floating of powder particles, the material passes through the screen with the airflow in the form of individual particles, fundamentally solving the problem of agglomeration and screen clogging, while ensuring sieving precision and efficiency. After four generations of technological innovation, the current airflow sieve integrates multiple functions such as feeding, agglomerate crushing and rough sieving, eliminating the need for additional feeding equipment and greatly reducing equipment investment and operation and maintenance costs.
In terms of performance, the YK-QLS Airflow Sieve boasts numerous advantages. The sieving efficiency can reach more than 95%, and the output is 5-10 times higher than that of traditional vibrating sieves or even more. It can efficiently process various difficult-to-sieve fine powders such as light calcium carbonate powder, traditional Chinese medicine powder, starch, graphite powder and pesticide powder, adapting to a wide fineness range of 50-530 meshes. The vertical screen installation design has no extra load, and the service life is more than 10 times longer than that of traditional equipment, effectively reducing the cost of consumable replacement. The fully closed negative pressure circulation operation mode completely eliminates dust emission, and combined with the low-noise operation feature, it not only ensures the cleanliness and safety of the operating environment, but also conforms to the environmental protection requirements of modern production. In addition, the equipment can be connected to mills, fans and other equipment for supporting use, flexibly integrating into the existing production process and meeting the needs of continuous production.
With its outstanding performance, the YK-QLS Airflow Sieve has deeply empowered the refined production of multiple industries. In the pharmaceutical industry, it can precisely sieve ultrafine traditional Chinese medicine powder and raw western medicine powder, ensuring the purity and particle size uniformity of medicines; in the food industry, it can efficiently sieve starch, fruit and vegetable powder, flour, etc., taking into account both hygiene standards and production efficiency; in the chemical industry, it adapts to the classification needs of calcium hydroxide, epoxy resin powder, fluorescent powder and other materials, providing high-quality raw materials for subsequent processing links; in the building materials industry, the precise sieving of quartz sand powder, clay powder, etc. helps improve the performance stability of building materials products. Whether for small and medium-sized laboratory research and development or large-scale industrial production, the airflow sieve can match the needs of different materials and output through parameter adjustment, becoming a core enabling equipment in the powder processing link.
As the requirements for product precision and production efficiency in various industries continue to rise, the YK-QLS Airflow Sieve, with its core advantages of high efficiency, precision, environmental protection and durability, is gradually replacing traditional sieving equipment and becoming the preferred solution for ultrafine powder processing. It not only solves the long-standing sieving problems in the industry, but also promotes the upgrading of production processes through technological innovation, helping enterprises improve product competitiveness and achieve efficient development in the wave of refined production.
