Overview of Wind Bag Airflow Screen Products:

The wind-driven airflow screening machine is a vibrating screening equipment that screens heavy, ultra light, and fine powders with a mesh, also known as a fine airflow screen or airflow vibrating screen. This machine is a high-precision screening equipment that screens fine powders with a mesh. In response to the increasing demand for fineness and accuracy of various powdered materials from users, Detai Machinery has developed a new product called the Airflow Vibration Screen Powder Machine, which has been widely used in industries such as chemical, pharmaceutical, food, papermaking, metallurgy, building materials, rubber, and machinery after years of research and trial production.

Principle of air flow screening with wind turbine:

The wind-driven airflow screening machine abandons the principle of gravitational potential energy operation and adopts the principle of using air as a carrier and kinetic energy as work. After mixing the material with air through negative pressure airflow, it enters the middle of the screening machine's wind turbine and applies sufficient centrifugal force through the wind turbine blades, spraying it through the bucket screen mesh and collecting it through the snail shell. Oversized materials cannot pass through the mesh and are discharged through the automatic slag discharge outlet to achieve rapid screening.

Technical parameters of wind turbine airflow screen:

Basic structure of wind turbine air flow screening machine:

A closed-loop screening and dust removal system is composed of a wind bag type airflow screening powder machine, a cyclone unloader, and a bag dust removal device. The host is a wind bag type air flow powder screening machine, and the closed shell of the upper screening body is equipped with a wind bag type circumferential cylindrical screen mesh; The inner side of the screen is equipped with a circular wind turbine, and the main shaft is driven by an electric motor installed inside the base to rotate at high speed before passing through the screen for screening.

There is a feeding hopper and coarse screen installed directly above the outer shell of the wind-driven airflow screen. There is a specially designed slag discharge port at the lower part of the air duct, and the motor is connected to the main shaft by a belt; The wind turbine forms a gap between the lower opening of the feeding hopper. The cyclone separation unloader and bag dust removal device are connected by a positive pressure induced draft fan through a plastic corrugated hose.

Application scope of wind bag air flow screening powder machine:

The wind-driven airflow screening machine is widely used for screening and grading powdered materials in industries such as chemical, papermaking, building materials, pharmaceuticals, food, rubber, plastics, machinery, and mining. Such as light calcium powder, heavy calcium powder, fly ash, graphite powder, starch, gold powder, zinc powder, sulfur powder, magnesium oxide, ceramic powder, pomegranate powder, perlite powder, hawthorn powder, fruit and vegetable powder, calcium hydroxide powder, pesticide powder, iron powder, traditional Chinese medicine powder, konjac flour, glitter powder, wood powder, flour, etc., according to the fineness requirements of the specially screened materials.
This machine can replace the screen mesh freely within the fineness range of 40 to 200 mesh. The screen mesh material can be stainless steel mesh, copper mesh, or nylon mesh. The screen mesh material can be ordinary steel type, stainless steel type, or ordinary steel anti-corrosion type; DeTai Machinery can also design air flow screening equipment such as air bag air flow screens, small-sized air flow screens, horizontal air flow screens, etc. based on the user's screening output and on-site size.

Maintenance and upkeep of the wind turbine air flow screen:

The operator of the airflow screening machine must strictly follow the requirements of the product manual and use the equipment correctly. Carry out daily maintenance work such as cleaning, lubrication, fastening, and corrosion prevention of equipment, so that the equipment is regularly maintained in a clean, high-performance, safe, and reliable state both inside and outside. The electrical control box should be kept clean to prevent dust from falling into the control box, causing electrical components to malfunction or short circuit. Regularly check whether the grounding wire is in good condition and whether the cable connection between the equipment and the power switch is good. If there is aging, it should be replaced in a timely manner. The main unit, motor, and fan of the air flow screen should be inspected once a year, and an appropriate amount of lubricating oil should be added to remove dust from the motor. The vibration exciter of the screening machine equipped with an exciter must be maintained once or twice a year, with lubricating oil added and connecting bolts tightened during each maintenance.

Precautions for the use of wind turbine airflow screens:

1. This machine is not suitable for screening materials with viscosity, moisture content greater than 5%, and flammable and explosive materials.

2. The larger the mesh size of the screened material, the lower the corresponding output of the airflow screening machine of the same model.

3. The screening standard mesh material should account for about 85% of the total material.

4. This machine can only screen out one type of material at a time. If multiple types of materials need to be obtained simultaneously, multiple machines need to be connected.

5. When replacing the mesh of the air flow screen, it is necessary to ensure uniform tension. When fixing the wire ropes at both ends, the mesh should be adjusted while tightening.
