Pneumatic conveyor calculations determine equipment capacity necessary to meet client requirements. If the sizing is wrong problems such as saltation and choking prevent bulk material flow. The goal of the pneumatic conveyor processes is to provide sufficient pick-up air flow velocity for optimal performance.

Conveyor belt speed calculation formula Where: V= Belt speed in m/s D= Roller diameter (mm) N= No of revolutions per minute. 2.Belt Length 3.Belt width Minimum belt width may be influenced by loading or transfer point requirements, or by material lump sizes.
Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

From David Mills 'Pneumatic conveying system design guide' the solid loading ratio (ɸ) is 0.5. Therefore, ṁ = ρ × A × v = 8000 Kg/hr = 2.2 Kg/s Were ρ is the density of the mixture, A is the area of cross-section of the pipe and v is the velocity of discharge.
All the conditions at the intake of a pneumatic conveying system are known. Therefore the intake is chosen as the start of the calculation. In vacuum- and pressure pneumatic conveying calculations, the used product properties are identical. The only difference is the mass flow, generated by a compressor in vacuum mode or pressure mode.

1.3 Design Tolerance The general principle of fluidized motion conveying is very simple and this method of conveying has a particular advantage of being essentially 'workable'. With pneumatic conveying systems it is critical that the conveying line inlet air velocity is correctly specified. Because air is compressible, and very much higher

Design and Fabrication of Pneumatic Conveyor System. Abstract-. Pneumatic conveying system is a conventional material handling system like belt conveyor or chain conveyor. The main advantage of pneumatic conveying system is that material is transferred in close loop, thereby preventing the environmental effect on the material and vice versa.
through selection of conveying system with auxiliary components to installation and plant commissioning. Design of required pneumatic equipment (includ- ing bulk solid feeders, air supply equipment, conveying pipelines and the air/solid classifiers) can come from a client's specification or from Claudius Peters' own material sample analysis.
A pneumatic system can convey a product at any place a pipe line can run. Pneumatic conveying can be used for particles ranging from fine powders to pellets and bulk densities of 16 to 3200 kg/m3 (1 to 200 lb/ft3). As a general rule, pneumatic conveying will work for particles up to 2 inches in diameter @ typical density. By "typical
