Introduction and Overview
The selection of the suitable components for a
­pneumatic conveying transfer system for dry bulk
­solid materials (pellets, granules, chips, regrind and
powders) is important for the function and the
­economical, reliable operation of an entire plant.
Unreliable components and equipment lead to high
maintenance costs and plant shut downs. This brochure
provides an overview, description and specifications
for the components and equipment necessary for
­reliable, efficient systems and guidelines for matching
components to specific application requirements.

Conveyor Station
Medium and High Pressure – CSM/H
Pneumatic conveying systems require a conveyor stack–up,
consisting of vent hopper, rotary valve, butterfly valve, feed
shoe and support stand, for the discharge of product from
the silo into the conveying line. The leakage air from the
­rotary valve is collected in a vent hopper and released to the
atmosphere or returned to the silo. When releasing to the
atmosphere, a filter is installed at the vent hopper.
A specially designed product discharge tube inside the vent
hopper drops the product directly into the rotary valve pockets
to prevent flow restriction of product through the leakage
air. For conveying lines with multiple pick-up points, it is
­necessary to seal the conveyor station that is not being used
with a butterfly valve.

Pelletron Air Regulation System – PAR
Pneumatic Conveying –
The Components
Rotary Valves and Accessories
Every conveying system that is fed by a central compressed
air network, either STRANDPHASE® or Dense Phase design,
requires an air volume control station that allows for constant
or variable metering of the air as it flows into the conveying
line. The Pelletron PAR station is equipped with Laval nozzles
providing the required mass flow even when conveying
­pressures on the downstream side fluctuate. In addition to
the Laval nozzle and pressure regulating valve, the standard
PAR station includes a safety pressure relief valve, pressure
transmitters, pressure gauges, by-pass orifice, manual and
automated shut-off valves, pre-wired junction box and piping.
The PAR manifold comes pre-piped, pre-wired, tested and is
available in a variety of sizes.
Rotary Valves for Hot Conveying
Depending on the polymerization and plastic production
process, some products need to be conveyed in a hot phase.
Pelletron provides specially designed valves for hot conveying,
either with electrical heating blankets or with steam heat­
ing. If steam is available in a plant, Pelletron recommends
using a steam heated valve for better heat distribution
throughout the rotary valve body. Heated valves are availa­ble
for a variety sizes and pressure ratings.
13
Dosing Rotors
For even and controlled product flow through a rotary valve
and into a conveying system, extruder or other processing
­machine, Pelletron offers special dosing rotors for all rotary
valve types. The depth and the width of the chambers are
calculated and designed to meet specific customer requirements.
Rotors
V-Shaped Rotors
For products like regrind with its characteristic uneven shape,
or nylon pellets, with their very high electro static charge,
Pelletron recommends the use of V-shaped rotors. In addition
to the standard anti-shearing device, this additional feature
prevents jamming and cutting of product. V-shape rotors
are available for a variety of valve sizes.
Shallow Pocket Rotors
To improve discharge performance for adhesive and sticky
pellets and powders, or for reducing product volume, the
use of a shallow pocket valve is recommended.
For most applications, the pockets are polished. Shallow
­pocket rotors are available for a variety of valve sizes.
Other Special Rotors
Pelletron offers a wide variety of rotors for special
applications. Special rotors features include:
Beveled vane tips for powder conveying and discharge to
reduce friction between the housing and the rotor tips
Exchangeable wear blades for conveying or discharge of
abrasive products

Polished valves for powder, food and pharmaceutical
applications

The Components
Open loop dedusting systems need an air intake filter to
supply clean air to the system. These filters are available in
a round design for easy maintenance of the filter cartridge
and equipped with a protection hood. For large scale systems,
rectangular air intake filters are available and a self-cleaning
pulse system is available upon request.

Dust Removal and Filtration
Inline filters are used in combination with closed loop CCD
dedusting systems that are installed after the cyclone. Pressure
rated inline filters, or safety filters, are common in pneumatic
conveying systems. Depending on the application, filters can
be supplied with a water separator. The standard filter
­construction material is stainless steel. The drawing to the
right shows a typical inline filter.

HEPA Filter
HEPA filters are used in dedusting systems that require the
highest possible cleaning efficiency. A HEPA filter is typically
installed after the air intake filter. Depending on the application
requirements, these filters are designed for filtration efficiency
of 99.97% at 0.3 micron. The filter housing is built to accommodate modular filter inserts. For easy access and maintenance, the filter housing is equipped with a side door for
easy filter replacement. The standard filter housing is made
in stainless steel and is available in a variety of sizes. The
drawing below shows a typical modular HEPA filter.

Wash Down DeDuster®
Wide Body Design
This design is based on a standard XP-design for wash down
­applications. The design allows for cleaning with water and
easy access to all areas of the DeDuster®.
For some retrofit applications, the available height is not
­sufficient for the installation of a standard DeDuster®. Pelletron
offers a wide body version of the P and XP-series in order to
reduce the construction height.

Pellbow®
The Working Principle
The Pellbow® Resists Wear – Naturally. In traditional long
­radius elbow installations, the conveyed product slides along
the elbow wall at a high velocity. The strong centrifugal
force presses the product against the outer metal surface.
This causes friction and heat, which creates streamers and
breakage. By design, material flowing through the Pellbow®
accumulates in the pocket or “impact zone” and moves slowly
upward and out. Incoming material is deflected at 90° with
minimum resistance and no impact damage.

Flange Connections
Pneumatic Conveying –
The Components
Piping Accessories
Air tight conveying lines are mandatory for all pneumatic
conveying systems. Pipes must remain tight under conditions
of extreme heat and extreme cold. For small pipe diameters,
it is common to use quick couplings, available in the market
from a variety of manufacturers. For large pipe diameter
­dilute, STRANDPHASE® and dense phase systems, we recommend using pipe connections with slip on flanges and solid
flange rings, designed and manufactured by Pelletron. These
flange connections are easy to install, airtight, mechanically
strong and withstand wide temperature variation.
These flange connections will be used for conveying line
pressures up to 50psi (3.5 bar). These flange connections are
available in AL, SST or a combination SST slip on flange with
AL or galvanized flange. They are designed to fit ASTM, DIN
and JIS piping. This drawing shows a typical flange connection.
Pipe Supports
For dilute and STRANDPHASE® conveying systems, standard
U-bolt pipe supports are commonly used to connect piping to
pipe bridges or other supports. The drawing below shows the
typical design. Pelletron can calculate the distance required for
proper support and calculate the force at each support point.
Dense phase conveying creates plugs that move through piping
under high pressure. The mass of the moving plug and the friction
created when plugs rub against pipe walls create strong pipe
forces. Special flexible pipe supports are required to allow the
pipes to absorb these forces. The bigger the conveying pipe
­diameter, the higher the forces and the more attention should
be given to the flexible support design. The photos to the right
show typical pipe supports for horizontal and vertical
­directions.
