Air-flow Sifter Machine

Product description

Airflow screen is an efficient screening equipment commonly used in industry. It consists of feeding, screening, air circulation and power system. When working, the material enters from the feed port, is suspended under the high-speed air flow of the fan, and is evenly sent to the screen. At this time, the air flow through the screen to form negative pressure, so that fine particles quickly through the screen, coarse particles under the action of the air flow and screen, along a specific trajectory on the screen surface until discharged from the discharge port. Because of its high screening accuracy, large processing capacity and low energy consumption, it is widely used in chemical, food, medicine, mining and other fields, effectively improving production efficiency and product quality.

Working principle

When the air screen works, the material enters from the feed port, then suffers the strong impact of high-speed air flow, and is quickly suspended and dispersed, effectively avoiding the problem of agglomeration and blockage, and can be evenly distributed on the screen surface. Under the continuous drive of the air flow, the fine particles in the material pass through the screen, and the coarse particles can not pass because the size is too large, and move along the screen surface under the synergic effect of the air flow and the screen, and finally discharge from the discharge port. This process relies on the exclusive air circulation system equipped with the air sieve, which is driven by the fan to circulate in the screen machine, which not only provides energy for the screening, but also ensures the stable and continuous air flow, but also conforms to the needs of various materials and screening by regulating the air speed, pressure and other parameters.

Product characteristics

1. High-precision screening: With the help of airflow precision screening, it can efficiently separate extremely fine particles, and the screening accuracy is extremely high. For example, in the production of chemical pigments, pigment particles with very small particle size differences can be accurately graded to meet the strict requirements of high-end products for the uniformity of raw material particle size.

2. Large processing capacity: the material is quickly screened under the high-speed air flow, and the amount of material processed per unit time is far more than the traditional screening equipment. In the grain processing industry, it can handle several tons of grain per hour, and efficiently complete the work of impurity removal and grading.

3. Low energy consumption operation: The design of the air circulation system is clever, using the energy of the air to achieve material conveying and screening, compared with other screening equipment that relies on a large number of mechanical operations, the energy consumption is significantly reduced, which can save considerable electricity costs for enterprises.

4. It is not easy to block: the material is screened in a suspended state, the screen is not easy to be blocked by the material, and the continuous working stability is strong. When dealing with high humidity, viscous materials such as starch, it can also run smoothly, reducing the number of shutdowns and cleaning.

5. Wide range of application: whether it is fine medical powder, easily oxidized metal powder, or large particles of ore and other materials with different properties and states, the airflow screen can complete the screening task, widely used in chemical industry, food, mining and many other fields.

Application

Chemical industry: can be used for screening of various chemical raw materials, such as plastic particles, rubber powder, paint pigments, fertilizers, activated carbon, etc. For example, in the production of plastics, airflow screens can grade plastic particles to ensure uniform product size and improve product quality.

Food industry: Suitable for screening of flour, starch, milk powder, powdered sugar, condiments, food additives and other materials. Taking flour production as an example, the airflow screen can remove impurities and coarse particles in flour to ensure the fineness and quality of flour.

Pharmaceutical industry: It has good screening effect for pharmaceutical intermediates, raw materials, pharmaceutical excipients, Chinese medicine powder, etc. For example, in the pharmaceutical process, the airflow screen can screen the drug powder into different particle sizes, which is convenient for the production of subsequent preparations and ensures the stability and effectiveness of the drug.

Mining: It can be used for the screening of metal mineral powder and non-metal mineral powder, such as quartz sand, kaolin, graphite powder, aluminum powder, etc. In the processing of kaolin, the air flow screen can remove the coarse particles and impurities, and improve the purity and whiteness of kaolin.

Other industries: Can also be used in abrasives, refractories, electronic materials, 3D printing materials and other fields. For example, in the production of 3D printing materials, the airflow screen can accurately screen metal powder or polymer material powder to meet the strict requirements of 3D printing for material particle size.
