In the production and experiments of chemical, pharmaceutical, food, building materials and other industries, high-precision sieving of fine powder is always a key link. However, when traditional vibrating sieves handle fine powders above 80 meshes, they are prone to agglomeration, screen clogging, dust flying, low sieving precision and other problems, which not only affect production efficiency, but also reduce the quality of finished products, becoming a pain point for enterprise production and laboratory research.
The YK-QLS Airflow Sieve launched by Yika (Shanghai) Technology Co., Ltd. takes aerodynamics as its core innovative operating principle and completely solves the problem of fine powder sieving. Abandoning the traditional gravitational potential energy operation mode, it takes air as the carrier and kinetic energy as the driving force. Through negative pressure airflow, the material is fully mixed with air and then jetted at high speed to the barrel-shaped screen. Oversized materials are discharged from the automatic slag discharge port, and qualified fine powder is collected through the volute to achieve rapid and precise classification. The whole process is carried out in a closed state, which not only solves the sieving problems of materials with high fiber content, high viscosity, low specific gravity and easy static electricity, but also fundamentally avoids dust flying, taking into account both production efficiency and operating environment.
As an efficient equipment specially for fine powder sieving, the advantages of the YK-QLS Airflow Sieve are reflected in every detail: the sieving efficiency can reach more than 95%, the screen penetration rate is 85%-95%, there is no oversized mixed grading phenomenon, and the screen residue is 0, far exceeding traditional vibrating sieves; the output is 5-10 times that of ordinary vibrating sieves, which can realize continuous sieving of 80-530 mesh fine powder and easily meet the sieving needs of 200-500 mesh ultrafine powder; the screen is installed vertically without load, and the continuous scouring of airflow realizes automatic screen cleaning, greatly extending the service life of the screen; at the same time, it has the characteristics of low noise and low power consumption, can operate continuously for 24 hours, and can be connected with various mills, air circuits and other equipment for supporting use, adapting to the diverse scenarios of industrial production and laboratory analysis.
In response to the precise demand for laboratory particle size analysis, the YK-QLS Airflow Sieve launched by Yika (Shanghai) Technology Co., Ltd. has achieved a core breakthrough with measurement accuracy < 1%, and the repeatability error is also < 1%, meeting the stringent requirements of the ASTM E11 international standard and the Chinese Pharmacopoeia. The deviation rate of the sieving results for lactose powder and other materials compared with the laser diffraction method is only 0.3%. The fully closed structure is matched with replaceable screens of 10-800 meshes, with a measurement range covering 15-5000μm. The low power of 180W can realize a 30% increase in processing capacity compared with traditional equipment. The transparent window design allows real-time observation of the sieving process, and the modular structure supports the quick disassembly and assembly of the main unit, negative pressure generator and sample collector, realizing a seamless switch between the laboratory and the production line.
The YK-QLS Airflow Sieve launched by Yika (Shanghai) Technology Co., Ltd. has been widely used in the sieving of various difficult-to-sieve fine powders such as light calcium carbonate powder, traditional Chinese medicine powder, starch, silica powder and alumina powder. In the pharmaceutical field, it ensures the uniformity of the particle size of raw materials and improves the dissolution rate and bioavailability of drugs; in the food industry, it precisely controls the fineness of flour, making the quality of baked products more stable; in the chemical field, it optimizes the dispersibility of plastic additives and antistatic agents, greatly improving the product qualification rate; in the laboratory, it provides precise data for particle size analysis and helps the smooth development of scientific research experiments.
The YK-QLS Airflow Sieve is exquisitely designed, sturdy and durable. Daily maintenance only requires simple operations and no professional personnel, greatly reducing the equipment operation and maintenance costs. Whether enterprises want to improve production efficiency and optimize finished product quality on the production line, or laboratories want to achieve high-precision particle size analysis, the airflow sieve, with its advantages of high precision, high efficiency and low loss, can become an ideal choice for fine powder sieving, bid farewell to screen clogging and low output, and escort production and scientific research!
