Heavy Duty Conveyor Roller Steel Pipe Conveyor Rollers For Mining
Machinery
Roller conveyors are suitable for conveying items with a flat
bottom, and are mainly composed of driving rollers, frames,
brackets, and driving parts. It has the characteristics of large
conveying capacity, fast speed, and brisk operation, which can
realize multi-variety co-line shunt conveying.
Structural form: From the driving form, it is divided into power, unpowered,
electric drum, etc. According to the layout form, it is divided
into horizontal conveying, inclined conveying and turning
conveying.
Size specifications: The inner width of the roller conveyor is specified by the
customer and can be made according to customer requirements. The
standard turning radius of the turning line is 300, 600, 900,
1200mm, etc., and other special specifications can also be used
according to customer needs. The diameters of the rollers used in
the straight rollers are 38, 50, 60, 76, 89mm and so on. The taper
of the turning drum will be designed according to the weight,
overall dimensions, and linear speed of the conveying object.
Frame material: carbon steel sprayed plastic, stainless steel, and aluminum
profile.
Power mode: geared motor drive, electric drum drive and other forms.
Transmission mode: single sprocket, double sprocket, O-belt, flat friction
transmission belt, timing belt, etc.
Speed regulation mode: frequency conversion speed regulation,
steeples speed change, etc.
Features of trough rollers
1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit
material.
2. Impact Rollers: Installed at the loading point to absorb the
shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its
return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt
deviation, preventing hunting and ensuring stable operation of
conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers
