2. Conveying Methods
Drag Conveying
– Material height being transported is less than or
equal to the flight height. This method applies to
horizontal or up to 10° incline conveyors.
Plastic Flights
En Masse Conveying
– Flight height can be as low as 12.5% of the
material height being transported in the
conveyor. This method applies to 25° to 90°
incline conveyors.

Drag Conveyor Material Depth En Masse Conveyor

3. En Masse Principle
Material, fed into the conveyor from the top, falls
through the moving chain to the bottom of the box.
Because the particles interlock, the material moves as
a single stream at the same speed as the chain.
This highly efficient conveying process allows nearly
the entire conveyor cross section to move as a bulk.

16. Product Testimonial - Bolt ‘N’ Go
To whom it may concern:
I have used 4B products such as elevator buckets, conveyor chain and motion
detection, with good results for many years. Our grain elevator handles several
commodities which include wheat, durum, and soybeans as the main products we
ship out and receive each year. We load grain by rail and ship and will load out
about 70,000,000 bushels a year.
We have several drag conveyors which use a forged steel chain with a typical pin
and circlip to assemble the chain. While this is a good and reliable assembly, it can
be very time consuming when changing out bent or broken chain flights.

In November of 2006 we installed a test section of 4B's new Bolt-n-Go chain and I
am quite pleased with the results. The Bolt-n-Go chain is very easy and fast to
install and maintain, as you eliminate the need to separate the chain each time while
installing a new flight. Also there is no need to slacken off the chain or re-tension
while changing flights. This alone will save untold hours on the routine maintenance
of these conveyors.
The Bolt-n-Go chain has been in service eight months and is running great with no
problems. As the old chain wears out I will definitely replace it with 4B Bolt-n-Go
chain.
