Air-flow Sifter Machine

Product description

Airflow screen is an excellent screening equipment, with a unique working mechanism and significant advantages, in the industrial field. When it is working, the material enters by the feed port, is instantly impacted by the high-speed air flow and suspended and dispersed, and is evenly spread on the screen surface. The fine particles pass through the screen easily under the push of the air flow, and the coarse particles move along the screen surface to the discharge port, and the whole process relies on the air circulation system to maintain a stable screening. It has a high screening accuracy, can accurately separate fine particles, processing capacity is far more than similar, and can handle a large number of materials per unit time. The energy consumption is very low, and the energy saving is significant with the help of clever air circulation. The screen is not easy to clog, has excellent continuous working performance, and can also adapt to various materials, from fine powder to larger particles, playing a key role in many industries such as chemical, food and mining.

Working principle

The airflow screen has excellent performance and significant advantages. In terms of screening accuracy, the principle of gas-solid two-phase flow can accurately separate micron or even sub-micron fine particles, which meets the strict requirements of particle size distribution in electronics, ceramics and other industries. The processing efficiency is high, the material is wrapped by high-speed air flow, and the flow field is optimized for fast screening, and the processing capacity per unit time is large. Low energy consumption, energy recovery by air circulation system, energy efficiency ratio far exceeds the traditional equipment. Good equipment stability, material suspension screening, reduce screen wear, avoid clogging, reduce maintenance costs. Its wide applicability, all kinds of materials can be efficiently screened, in a variety of industries to perform well.
When working, the material enters from the feed port and is suspended and dispersed on the screen surface by the impact of high-speed air flow. The fine particles pass through the screen by air flow, and the coarse particles move along the screen surface to the discharge port because of their large size. The fan drives the air circulation to supply energy for the screening, and ADAPTS different materials and screening requirements by regulating the air flow parameters.

Product characteristics

1. High precision screening
Using airflow classification technology, the screening accuracy is up to micron level. Precise regulation of air flow and screen parameters can meet the strict requirements of raw material particle size in electronic component manufacturing and other industries, and effectively improve product quality consistency.

2. High throughput
Unique structure and strong airflow drive, the material flow in the screen quickly. Like grain processing, several tons to tens of tons of grain can be processed per hour. Material suspension screening, greatly shorten the screening time, to meet the needs of large-scale production.

3. Low energy operation
Optimized air circulation path, fan air circulation utilization, energy consumption than the traditional equipment is reduced by 30%-50%. Power system design is reasonable, energy saving while ensuring efficient screening, helping enterprises to reduce costs.

4. Not easy to clog
The material is suspended throughout the screening process, and the way of contacting the screen is special. Handling sticky, easy to aggregate materials (such as starch) is also not easy to block the net, the equipment can run stably for a long time, reduce downtime and maintenance, and improve the utilization rate.

5. Wide range of application
Can screen dry (cement, etc.), wet (food slurry, etc.), special properties (easy oxidation, flammable and explosive) materials. By adjusting air flow parameters and equipment structure, it is widely used in chemical, food, medicine, mining and other industries.

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.
