Why use pneumatic conveying to move bulk solids? With the appropriate choice of system, material can be transported with minimal degradation Little or no exposure of the product to the environment Can transport relatively long distances (several thousand feet) Excellent for multiple sources and multiple destinations Ability to transport material which might be air, moisture, etc. sensitive
rate, using an existing conveying line. •Sizing of the conveying line for a specific solids transfer rate using existing gas supply. • Modifying any of the above by increasing the line diameter along the conveying line to maintain a specific conveying velocity or a terminal velocity, or a maximum conveying pressure. 1.
Powder ProcessSolutions supplies powder handling systems of all types to store, convey, blend, screen, weigh, mill, transport, discharge and pack dry bulk and semisolid powders and granules. System design may incorporate either dilute or dense phase pneumatic conveying principles, and selection is dependent on the product and its applications.
The key difference between pneumatic and hydraulic/slurry conveying of solids is that the carrier gas will expand continuously as it goes along the pipe. The flow regime in the pipe (dense or dilute phase) will depend on the ratio of gas to solids and the characteristics of the particles.
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.
Nov 21, 2017· Gravity Conveying versus Mechanical Conveying versus Pneumatic Conveying If you need to move material from one process to another, gravity is a nice way to do it. The nicest things about gravity are: 1) it''s free; 2) It always works (or at least, if it stops working, you probably will have more pressing issues than your material handling system).

A Quick Check Method For The Design Of Pneumatic Conveying Systems by Dr David Mills, Pneumatic Conveying Consultant, Old Wives Lees, England INTRODUCTION The design of pneumatic conveying systems is usually carried out on the basis of scaling data obtained from the pneumatic conveying of the material to be transported. If previ
A typical example of a pneumatic conveying system that we engineer and manufacture involves conveying a material (such as polymer, lime, soda ash, plastic pellets/powder, dry milk etc.) from a railcar or truck to a silo (or vice versa). Other applications include intermodal/transloading, inplant transfer, dust control, and portable solutions.
