What Is an Air Conveyor?

The air chute conveyor refers to the equipment for horizontally conveying dry powdery materials (such as cement and raw materials in cement enterprises). It is composed of several thin steel slot joints, and is arranged at a certain slope along its conveying direction. A vent layer is sandwiched between the upper and lower shells of the slot.

The air chute conveyor refers to the equipment for horizontally conveying dry powdery materials (such as cement and raw materials in cement enterprises). It is made up of several trough connections made of thin steel and along its conveying direction

The high end of the conveyed material is fed into the upper casing, and the compressed air is blown into the lower casing by a special blower, and is distributed between the particles of the material through a porous layer with dense pores, so that the material is so-called gasified to change the friction angle of the material. , To form a flow state and slide along the slope to achieve the purpose of transportation.

Because the air chute has no transmission parts in the conveying material, it has less wear, easier maintenance, less power consumption, less material consumption, no noise, and airtightness compared with its equivalent belt conveyor, screw conveyor, and buried scraper conveyor. Good, simple structure, safe and reliable operation, and easy to change the conveying direction and multi-point feeding, unloading and other advantages. Therefore, it has been adopted by many enterprises in recent years ^[1]

1. Conveying materials: dry powdery materials.

2. Conveying capacity: The conveying capacity of the chute is affected by many factors and often varies greatly. Based on theoretical calculations of reference materials at home and abroad, and comprehensive analysis of field surveys, the following values are recommended for users' reference when the slope is 6%.

Chute width (mm)	Capacity) (cubic meters / hour)
250	~ 30
315	~ 60
400	~ 120
500	~ 200

3. Inclination: 6% straight inclined groove is not affected by the flange structure, and the slope can be selected arbitrarily. It is recommended that the slope of the rough material in the transport cycle be 10%. Generally speaking, when the layout is possible and the abrasion of the ventilation layer allows, it is advantageous to use a large slope.

4. Air Consumption: 1.5 ~ 3m3 / min, square meter ventilation layer. Various materials and their conditions, the condition of the ventilation layer, the slope of the chute, have different degrees of influence on the air consumption. Generally can be considered as 2 (cubic meters / minute, square meters of ventilation layer).

5. Air pressure: 400 ~ 600 water column (mm). For large specifications and long chute, take a larger value. Generally considered as 500 (mm of water column).
