Conveying MethodsConveying Methods

Plastic Flights

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.

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.

En Masse PrincipleEn 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.

Product Testimonial Product Testimonial -- Bolt Bolt ‘‘NN’’ GoGo

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.
