In dilute phase pneumatic conveying systems the particles are carried suspended in the air through an enclosed pipeline. Typical values in lean phase conveying are pressure ΔP from 0 2 to 0 8 bar for pressure systems from 0 2 to 0 5bar for vacuum systems. conveying speed between 18 and 30 m/s (depending on flow rate and material
Nov 11 2022Highlights . The global Dilute Phase Pneumatic Conveying System market is projected to reach USD million by 2028 from an estimated USD million in 2022 at a CAGR of during 2023 and 2028.
In open end pipe line suspension flow or dilute phase pneumatic conveying proper particle velocity is critical to continuing productivity and product quality. Until recently measurement of actual particle velocity within the pipe has not been practical outside the laboratory. The plant operating personnel depend on a much less accurate metric estimating the conveying air velocity in the
The difference between dense phase conveying and dilute phase conveying is that in the case of dense phase conveying solid to air ratio is high (above 12) () and 1 kg of air or conveying medium is used to convey more of the solids. Normally the three phases are represented as follows Dilute Phase = solid to air ratio up to 6 Medium

Vacuum semidilute phase conveying systems provide an efficient way to convey powders in a gentle manner where product degradation continuous product flow and/or segregation are process concerns. While not operating in a true dense phase manner these semidilute phase systems provide many of the benefits of dense phase systems while
In dilute phase pneumatic conveying the material is conveyed in suspension in the pipeline with the help of air. Velocity ranging from 1835m/s can be used. The dilute phase systems are again classified as positive pressure and vacuum operated systems based on the application as well as the type of powder that is to be conveyed.
For dilute phase Vacuum pumps used in dilutephase conveying systems must be able to sustain a vacuum of 1012 inHg at the pump outlet while providing an air "pickup" velocity of 3 500 to 4 000 feet per minute (2 800 to 3 200 fpm pellet velocity) at the most distant pickup point in the conveying system. Any of the four vacuum pump types
Figure illustrates the case of a dilute phase conveying system typically for a longdistance conveying minimum conveying air velocity that must be maintained for the material is about 15 m/s and 60 m 3 /min of free air is available to convey the material. The conveyingline inlet air pressure is 4 bar gauge. Figure shows that a 125 mm bore pipeline will be required
Dilute phase vacuum conveying systems are ideal for transporting dry bulk solids at low to moderate capacities with low operating pressures over medium distances. These systems are also ideal for conveying bulk materials that tend to pack or compress under pressure and these materials may include pigments wood shavings chemical powders food
The system will successfully convey bulk materials by controlling vacuum airflow forces and pressure inside the conveying line. This pneumatic conveying system comes in two types. First is dilute phase and second is dense phase. Both of the types work for different purposes according to their names. Let us compare both of the types.

Fines are generated with the friction of mechanical conveyor or speed of dilute phase pneumatic convey systems. Dense phase vacuum conveying will move the material gently and slowly. The only friction will be the contact between the outer particles with the sidewall of a smooth tube. Dense phase allows the particles to travel at a slow
Dilute Phase Vacuum Conveying Systems are particularly suitable for systems which convey materials at low to moderate capacities over medium distances from multiple points to a single destination. These systems are versatile and adaptable for different materials and the low operating pressures allow lower cost pipelines and fittings. This
Dilute phase conveying. As mentioned earlier anything can be conveyed in dilute phase and some typical minimum values of conveying air velocity were given and these apply to both positivepressure and vacuum conveying. If the value of the conveyingline inlet air velocity drops below the minimum value for the material being conveyed the
In pressure conveying a high volume of lowpressure air transfers material at a high velocity. In vacuum conveying a high volume of negativepressure air transfers material at a high speed. Common materials suitable for dilute phase pneumatic conveying are flours resins compounds specialty chemicals and others.
Dilute phase discontinuous vacuum conveying of raw materials Dilute phase continuous vacuum conveying of raw materials. Semidense phase vacuum conveying. Semidense phase vacuum conveying allows a gentle product flow down to the material saltation point where particles are moved away from sediments by the pure force of the gas velocity. It is
Apr 19 2022Resin in a conventional highspeed dilutephase vacuumconveying line accelerates continuously from the pickup point to the destination. Consequently pellets that may have been picked up at a reasonable 3500 to 4000 ft/min rate will be racing at well over 5000 ft/min (and creating angel hair) by the time they reach the end of an 800 or 1000
Dilute phase pneumatic conveying sometimes also referred to as lean phase or suspension flow is a mode of conveying where the material is kept in suspension in the air stream of the pipeline it is being conveyed in. This mode of conveying can be in either in a positive pressure system (blowing system) or a negative pressure system (vacuum

The dilute phase conveying systems are usually provided when particle size distribution varies from microns to millimeters. This lean phase pneumatic conveying system is lowpressure highvelocity systems that have the utmost flexibility for the kind of range of materials that can be handled. The airflow is generated with vacuum pumps
Common Differences Between Dilute Phase Pressure Conveying and Dilute Phase Vacuum Conveying. Dilute phase pneumatic conveying is a method of moving nonabrasive nonfragile materials that have a low bulk density. The materials move along an enclosed pipe in slug form using small amounts of gas at a high velocity and low pressure. This
Dilute Phase Vacuum The air is sucked through a filter at the destination
Dilute phase conveying systems offer an alternative to mechanical conveying systems such as screw conveyors belt conveyors or bucket elevators.
2. Dilute Phase Vacuum Conveying . In contrast for dilute phase vacuum conveying the positive displacement blower (exhauster) is placed at the end of the conveying line. Here the blower draws the air from the beginning of the conveying line to create an airflow that moves the material through the conveying pipe into the receiver.
