In pneumatic slide systems, it is critical to make accurate fan and installation calculations for efficient and continuous transportation of materials. The overall performance of the system depends on the fluidization air being provided at the correct pressure and flow rates. When making these calculations, parameters such as the physical properties of the material to be transported, the geometry of the system and the total transportation length should be taken into consideration.
1. Fan Calculations Fans used in air slide lines provide fluidization air and allow materials to move in a fluid state.
1.1. The following criteria are taken into account in fan selection: Flow rate (m³/hour): Calculated depending on the density of the material, the amount to be transported and the length of the line. A high flow rate requirement requires the selection of a powerful fan.
1.2. Pressure (mbar): The fan must operate at the correct pressure level in order for the fluidization air to provide the necessary energy throughout the entire length of the system. The line’s inclination angle, pipe diameter and friction losses are taken into account when making the calculation.
1.3. Material Properties: The specific gravity, grain size and moisture content of the material being transported play an important role in determining the fan capacity.
2. Installation Calculations The installation design of the air slide line should be made in a way that optimizes both the material flow and air movement.
2.1. Air Distribution: Providing an equal air distribution throughout the line is essential for the smooth transportation of materials. This is achieved by using pipes of appropriate diameters, air adjustment valves and flow regulators.
2.2. Pipe and Line Dimensions: Pipe diameters and line lengths are carefully calculated to minimize air friction losses. When necessary, friction-reducing coatings are applied to the inner surface of the pipe.
2.3. Slope Angle: The slope angle of the air slide line is a critical parameter for the material to flow in a fluidized state. Generally, a slope between 5° and 12° is sufficient.
