Air-flow Sifter Machine

Product description

The air flow screen is a screening device that uses air flow as the vibration source. Its working principle is that the air flow generated by the fan drives the screen mesh to vibrate at high frequency, causing the materials to move forward in a spiral shape on the screen surface and be screened layer by layer. This equipment features high screening efficiency and precision. It can handle fine powder, micro-powder and other materials, and is suitable for industries such as chemical engineering, food, medicine, and non-metallic minerals. It can effectively solve the problem of screen blockage caused by fine particle size and high moisture content of materials. Moreover, it has the advantages of compact structure, low energy consumption, and simple operation and maintenance. It can achieve automated continuous production. It is widely applied in the field of ultrafine powder classification.

Working principle

The air flow screen uses a fan to generate directional air flow as the power source, enabling efficient screening of materials on the surface of the screen. After the materials fall into the screen body from the feed port, they are suspended under the action of the air flow field and collide with the screen at high frequency. Fine particles pass through the screen holes due to the buoyancy of the air flow and become under-screen materials, while coarse particles move along the screen towards the discharge port and are discharged. Some of the equipment is supplemented with mechanical vibration to prevent the screen holes from being clogged. It uses air flow to replace traditional mechanical vibration, which is particularly suitable for the ultra-fine classification of fine powder, micro powder, high humidity or easily agglomerated materials. It has the advantages of high screening accuracy, low energy consumption and less likely to clog the screen.

Product characteristics

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.
