Pneumatic Conveying Systems

PETROSADID Company is the renowned Iranian supplier of full range of pneumatic conveying Equipment suitable for a wide range of industries such as Petrochemicals, Soaps and Detergents, Food and Pharma, Minerals and Metals, Chemicals, Cement and fly ash, Power, Foundry, Glass and Ceramics, Paints and Pigments, Inks and Resins, Rubber, Agriproduct, Ports, Paper and Newsprint and etc.

Our range will be customized as per the technical specifications provided by our clients to suit customer's need. Pneumatic Conveying is a cost- and energy-efficient method of transporting dry bulk materials such as powders and granules through an enclosed pipeline from one place to another.

The motive force for this transfer comes from a combination of pressure differential and the flow of a gas, such as air or nitrogen.

A typical example of a pneumatic conveying system that we provide and supply involves conveying material (such as polymer, lime, soda, Fly ash, plastic pellets/powder, dry milk etc.) from a railcar or truck to a silo (or vice versa).

The basic components of a pneumatic conveying system:

• An air mover (blower package)

• Conveying line from vessel containing material (header)

• Blow Pot (temporary vessel that feeds material into the line)

• Conveying line to discharge vessel (up to top of silo)

• Discharge vessel (silo)

• Filtration system to separate the solids from the gas (air) at the end of the system (bin vent)

• A control panel to control and automate functions of the system

1- The blower motor starts and then turns the shaft of the blower via belts or direct drive. The blower intakes filtered air, compresses it, and then pushes it through the line.

2- The pot then utilizes a proprietary venturi system to induce a vacuum and the material is vacuumed from the railcar into the Pot.

3- Either by sensor automation or by manual control, the system will switch from vacuum to pressure mode and the material is blown through the convey lines and into the silo.

4- This process continues at high rates until the car is empty.

Advantages of pneumatic conveying system:

1- Cost savings in freight rate of bulk materials.

2- Savings in the elimination of packaging costs of smaller bags and containers.

3- Closed system conveying reduces cross-contamination.

4- Routing flexibility – can be transported to remote areas of plant, vertically and horizontally

5- Occupy less space

6- Easy dust control

7- Can have several pick-up points and routes controlled with valves.

8- Lower maintenance, power, and labor costs.

9- Wide variety of materials can be conveyed

10- Ease of automation and control

Pneumatic conveying systems are classified by their operating principle into two basic types: dilute phase and dense phase. Either can run under pressure or vacuum.

Dilute phase conveying systems:

The dilute phase conveying, also known as "low temperature" conveying, is characterized by a low efficient ratio, usually lower than 5 kg product per kg of air.

Dense phase conveying systems:

The dense phase conveying moves the product at relatively slow speed, reducing the risk of product degradation and the abrasion of pipe-lines, bends and diverters.

Dense phase pressure conveying reduces air consumption and product degradation, determining an efficient ratio between the material conveyed and the need air (product kg and air kg)
