The air conveying chute is used for the horizontal conveying of dry powder materials. It is composed of several grooves made of thin steel and arranged with a certain slope along its conveying direction. The chute consists of several grooves made of ordinary thin steel plates and other accessories connected by bolts. A breathable layer is sandwiched between the upper and lower shells of the chute, and the chute is inclined at a certain angle to the horizontal plane. The main component of the chute is a new type of breathable layer, which has the advantages of high temperature resistance (150 ℃), corrosion resistance, wear resistance, low moisture absorption, light weight, smooth surface and long service life.

The air conveying chute is a device that uses the kinetic energy of the airflow to suspend the particulate material along the pipeline with the airflow. There are three modes of transport: suction, pressure and hybrid. The main part of the air delivery chute has no transmission part. The new coated wheel breathable layer is used to facilitate sealing operation and management. The device is light in weight, low in power consumption, high in transmission power, and easy to change the transmission direction.

The air conveying chute is mainly used for cement, fly ash and other powder materials that are easy to fluidization. The chute uses a high-pressure centrifugal fan as the power source to make the material in the closed conveying chute flow slowly at the inclined end in a fluidized state. Air conveying chute is a kind of pneumatic conveying equipment widely used for conveying dry powder materials. It is often used for conveying cement and raw material powder in the cement industry. Air chute is used for horizontal conveying of dry powder materials. Air chute is mainly used for cement, fly ash and other easily fluidized powder materials. The chute uses a high-pressure centrifugal fan as the power source to keep the material in the closed conveying chute fluidized, and the inclined end flows slowly.

The power method of the air conveying chute: the high end of the conveying material is sent to the upper shell, the compressed air is blown into the lower shell by a specially designed blower, and is distributed between the material particles through the porous breathable layer, so that the material is gasified, thereby Changing the friction angle of the material, forming a flow state and sliding along the slope to achieve the purpose of conveying.

The circular vibrating screen adopts cylindrical eccentric shaft vibrator and eccentric block to adjust the amplitude. Material sieves have long flow lines and multiple sieving specifications. The circular vibrating screen has the characteristics of reliable structure, strong excitation force, high screening efficiency, low vibration and noise, sturdy and durable heavy-duty disc feeder, convenient maintenance, and safe use.

Influencing factors:

1. The air permeability of the air hole plate. There are many materials for the air hole plate, such as porous ceramic plate and composite material, which should be selected according to the specific situation.

2. Install the tilt angle. The inclination angle of the air conveying chute for conveying fly ash is 5 °-6 °.

3. The width of the air delivery chute. The conveying capacity and tank width can be expressed by the following empirical formula: M = conveying capacity of the air conveying chute, kg/s,K = constant, = bulk density of fly ash in the chute at full fluidization, kg/,B = chute width, M.

4. Air for transportation. The working pressure of the fluidizing air in the air conveying chute is generally 3.5-5Kpa, and the air consumption is 2-3/㎡. min, that is, the effective ventilation area of the air orifice plate per square meter consumes 2-3 air per minute.
