TRL
High Pressure Blowers
A powerful and flexible conveying system
Applications
Ideal for conveying, drying, ventilating and extraction in grain
handling installations.
The use of the TRL high-pressure blower for conveying purposes
ensures an entirely self-cleaning system which is not limited by
the lay-out of the flow arrangement - whether vertical, horizontal,
around corners or from one building to another. The system is ideal
for farms requiring flexibility in conveying and processing different
crops.
In Addition to conveying and ventilating, the TRL75
may be used for drying / conditioning.
Features
- Modular Design – All self contained components.
- Flexible – the same equipment can be
varied as required.
- Self Cleaning – conveying system.
- Easy to install – with use of OK pipe
system.
- Universal connections – All blowers use
the same pipe system.

The high-pressure blowers are available in a wide range of sizes
to match any specific conveyance requirement.

Operation
Pressure Conveying

The conveying line is connected to the blower’s outlet. The
blower generates a powerful air stream through the pipes. The material
to be conveyed is fed into the pipe system via an intake unit (venturi
or rotary valve). By means of diverters the flow may be directed
to different destinations.
Suction Conveying

Suction is used, for instance, when the material is delivered to
a cleaner. At the same time, part of the dust is separated from
the grain. The crop is sucked from the grain pit or store using
a suction head. The material is pulled through the pipe system and
is delivered to the cleaner via a cyclone and rotary valve. The
dust may be discharged to the open or to a set of filter bags.
