the system is called as Dense phase pneumatic conveying system. Generally high air velocities (e.g. 20 to 40 m s −1 ) have to be used in suspension flow and values above about 50 indicate that a material is capable of being conveyed at low velocity in dense phase. The data in Figure 1 represents the pressure gradient for conveying material through straight horizontal pipeline of 2 inch bore. As will be seen,
