Introduction Pneumatic conveying of solid particles in channel or pipe flows is of great technical importance and therefore found in numerous areas of process engineering such as chemical, pharmaceutical and food industries, power generation (conveying of pulverised coal) and air conditioning technology.
Recommended air velocity for pneumatic transport of products like cement, coal, flour and more.
The heart of the pneumatic conveying system (air mover, solids feeder, pipeline, and separator) is the air mover. Correctly specifying the volumetric flow rate and pressure levels required to move the material will determine system reliability. One must also look at pipe size, distance, and the weight of the material being moved. A company specializing in …

The calculations for the design of a dilute phase conveying sys-tem are based on determining the pressure drop that is gener-ated in the system due to the flow of gas and solids.
The design of pneumatic conveying systems is usually car-ried out on the basis of scaling data obtained from the pneu-matic conveying of the material to be transported. If previ-ous experience of conveying a given material is not avail-able, data is generally derived for the purpose by conveying the material through a test facility. Most manufacturers of …
In solids processing systems, it is commonly required to transport solids from one location to another. Solids can be transported via various means, including (1) pneumatic conveying, in which solids are transported in a pipe or channel by gas flow through blowing or suction; (2) gravity chutes, where solids transport downward by …
A dilute phase pneumatic conveying system is a method of moving bulk materials using air or gas as a medium. In this system, materials are transported as suspended particles, achieving high speeds to ensure they remain airborne. As the system operates at relatively lower pressures and higher velocities, precise calculations are …
Dense phase conveying (DPF) is slow conveying, which is operated close to the respective conveying limit and with which, in general, only a limited amount of bulk materials can be conveyed stably. To increase operational reliability and to expand the application range of conventional dense phase conveying, DPF methods have been …
Prior to performing the calculations, a brief overview of dense phase pneumatic conveying is helpful to understand. Dense phase pneumatic conveying is a method for moving difficult, heavy (normally greater than 50-60 lb/cu ft) abrasive, mixed batch, or friable materials at a low product velocity.
An empirical model to calculate the pipe line pressure loss for a pneumatic conveying system is described. The model was originally proposed for lean phase conveying and is modified to use solids friction proposed by Weber (1982). The calculated pressure loss for a given pipe diameter, pipe length, air mass flow rate and material mass flow rate is …
