Wind Sifter Topic

Wind Sifter(air separator) is a device that uses airflow to sort and classify materials. As a mechanical device that sorts materials based on the difference in the suspension speed of materials in the airflow. Wind Sifter is an efficient, environmentally friendly and energy-saving sorting equipment.

Wind Sifter

The Wind Sifter(air separator) uses the different suspension speeds of materials in the airflow to achieve separation. When the material is fed into the sorting area of the Wind Sifter, the airflow generated by the fan will act on the material. Due to the differences in the components of the material (such as density, shape, particle size, etc.), they will be subject to different airflow forces, resulting in different movement trajectories. Materials with low density, light weight and large surface area are easily carried away by the airflow, while materials with high density, heavy weight and small surface area are not easily carried away by the airflow, and thus fall under the action of gravity. By adjusting the speed, direction and other parameters of the airflow, effective separation of materials can be achieved.

The Wind Sifter is based on the difference in the different movement speeds and densities of materials in the airflow. When the material enters the Wind Sifter through the feed port, the airflow generated by the fan will act on the material. Due to the differences in density, shape, particle size, and suspension speed of different components in the material, they will be subject to different airflow forces. Lightweight materials with low density, large surface area, and greater wind resistance (such as plastic film, paper, foam, etc.) will be blown up by the airflow and move in the direction of the airflow; while heavier materials will fall under the action of gravity due to the smaller wind force. By adjusting the fan speed, blade angle and other parameters, the intensity and characteristics of the airflow can be changed to meet the sorting needs of different materials.

Wind Sifter

The structure of the Wind Sifter usually includes the feed port, sorting chamber, fan system, discharge port, and dust removal device. Among them, the sorting chamber is the core component of the Wind Sifter, and its internal structure is reasonably designed to ensure full contact and separation of the materials in the airflow. The fan system provides a stable airflow, which is the key to the normal operation of the Wind Sifter. The discharge port is used to export the separated materials, and the dust removal device is used to collect and process the generated dust to keep the working environment clean.

Wind Sifters are widely used in many industries, including but not limited to food processing, chemical industry, metallurgy, mining, garbage disposal and industrial waste recycling. In the food processing industry, Wind Sifters are often used to remove impurities and defective products from grains; in the chemical industry, Wind Sifters can be used for grading and sorting of powdered materials; in the metallurgical and mining fields, Wind Sifters are used for the selection and separation of ores; in garbage disposal and industrial waste recycling, Wind Sifters can efficiently separate recyclables and hazardous substances.

The working principle of the Wind Sifter(air separator) is mainly based on the difference in the movement characteristics of different substances in the air flow. It is a device that uses aerodynamic principles to separate materials. It is widely used in many fields such as waste recycling, agricultural processing, and food processing. It distinguishes materials of different densities, shapes, and sizes by adjusting the speed and direction of the air flow. Below, the editor of Zhongcheng Machinery introduces the working principle and structural composition of the Wind Sifter:

A. Working principle of the Wind Sifter:

Working principle picture of wind sifter

The Wind Sifter generates airflow through the fan, and the material enters the air separation chamber through the feed port. When the airflow passes through the material, it will be separated based on the material's density, surface area, and wind resistance. Specifically, lightweight materials with low density, large surface area, and high wind resistance (such as plastic film, paper, foam, etc.) will be blown up by the airflow and move in the direction of the airflow, thereby achieving separation from heavier materials. Materials with high density, small surface area, and low wind resistance (such as bricks, stones, etc.) will fall under the action of gravity due to the small wind force.

1. Feeding system: The material is first fed into the feed port of the Wind Sifter, usually at a uniform speed and in a uniform manner to ensure the stability and accuracy of the subsequent separation process.

2. Airflow generation: The Wind Sifter is equipped with devices such as fans or blowers to generate strong airflow. Depending on the needs, these devices can provide directional or non-directional airflow, and sometimes combine multiple airflow sources to optimize the separation effect.

3. Material suspension and transportation: When the material enters the airflow, the lighter material will be carried away by the airflow and suspended in the air, while the heavier material will fall directly or move along a specific path due to its own weight.

4. Separation mechanism:

a. Separation by density: For materials of different densities, the Wind Sifter uses the difference in their floating characteristics under the same airflow conditions to separate them. Lighter materials are easily carried away by the airflow, while heavier materials will settle faster.

b. Separation by shape and size: The shape and size of the material will also affect its behavior in the airflow. For example, flat or flaky materials may be more susceptible to airflow, thus achieving better separation.

5. Collection system: The separated materials enter different collection areas. Light materials are usually directed to the collection area at the top or side, while heavy materials fall into the collection device at the bottom.

6. Adjustment and control: In order to adapt to different types of materials and achieve the best separation effect, the Wind Sifter is usually equipped with adjustable parameters, such as airflow speed, angle, air volume, etc. Operators can adjust these parameters according to actual conditions to ensure efficient and accurate sorting.

B. Structural composition and function of Wind Sifter:

The Wind Sifter is generally composed of a feed port, a sorting chamber, a discharge port, a fan, and a dust removal device.

1. Feed system: Responsible for evenly and stably conveying the mixed materials to be sorted to the sorting area of the Wind Sifter, ensuring that the flow rate and distribution state of the materials when entering are controllable, laying the foundation for subsequent precise sorting.

2. Sorting chamber: The core component of the Wind Sifter, its internal structure is carefully designed, including airflow guide devices, baffles, etc. The airflow guide device is used to control the speed, direction and distribution of the airflow, so that the material can fully contact the airflow in the chamber and produce different motion trajectories according to its own characteristics; the baffle helps to further adjust the flow direction and separation effect of the material to prevent disordered mixing of the material.

3. Fan system: It produces a stable and adjustable airflow and is the power source for the operation of the Wind Sifter.

4. Discharge system: It includes a light material discharge port and a heavy material discharge port, which respectively guide the light and heavy materials after sorting out of the Wind Sifter for subsequent collection, packaging and further processing.

5. Dust removal device: During the air separation process, the turning of the material will generate dust. The dust removal device is used to collect and process the dust to prevent the dust from being blown out and causing environmental pollution. It is also beneficial to protect the health of the operator and the normal operation of the equipment.

PS: With its unique airflow separation technology, the Wind Sifter provides fast and effective material sorting solutions in many industries. By accurately controlling the airflow parameters, it can achieve fine classification of materials and meet the requirements of various production processes.
