Belt
Conveyor belts are used in a wide variety ofmaterial transport applications such asmanufacturing, food processing, and heavyindustry.
Commercial applications include:
• Agriculture
•
Construction - heavy building materials• Food and beverage processing
• Forestry - logging, sawmill, paper pulp, etc.
• Mining and quarrying
• Factory production line

Cont.$
%isadvantage
operates at relatively low rotational speeds
Abrasive problems arise at high speed
&ower consumption per unit weight
transferred is high

&oller A roller trac* for a storage rac* or roller conveyor, comprising a wall
arrangement, and a longitudinally-e$tending array of freely rotatable roller
units supported on the wall for supportive engagement with a load, the roller
units being disposed for rotation about generally parallel hori"ontal a$es
which are hori"ontally spaced along a longitudinally-e$tending conveying
direction, each roller unit including an annular roller housing supported
through an annular array of antifriction bearing elements on a support spindlefor rotation about the respective hori"ontal a$is.

'ibrating 1ibrating conveyor2s operation is typically
based on the natural frequency principle. Atthe natural frequency, the conveyor will
vibrate indefinitely with only a small energy
input. 3nce the drive initiates the conveyor4s
vibration, the supporting springs, by
alternately storing and releasing most of the
required energy, help maintain constant motionunder the conveyed load.
!epending on the frequency and the si"e of
the ob/ect can reach speeds as high as 56 fpm
7o programming is needed, uses an on or off
system to control it
