CONVEYOR IDLERS
SALIENT FEATURE
* Conforms to IS:8598-1987.
* Minimum roller gap to maximize belt life as it eliminates
danger of pinching and damaging belt.
* Forward tilt of side rollers ensures proper belt
training.
* 'Drop in type' design facilitates easy mounting
and removal of rollers.
FRAME
Jig welded steel frame ensures precise roller alignment
and inter changeability.
Inverted angle base provides strength, and directs
spillage away from rollers thus preventing accumulation
of material under roller, ensuring free running of
roller without any power loss.
Foot straps each with two open end slot facilitate
initial alignment of belt.
ROLLER Roller shell is made of special ERW tubes with
close tolerance.
Bearing housings pressed out of CRCA steel sheet are
welded to the roller shell with the help of Co2 welding
machine to achieve least distortion and maximum strength.
All rollers are made free before dispatch.
Close tolerance solid shaft protects bearings by minimizing
deflection.
Rollers are fitted with seize resistant ball bearings.
These bearings are specially designed for Belt Conveyor
applications.
Double multilabyrinth seals ensures maximum protection
against dirt, dust and moisture to the bearings.
Bearing, seals and grease chambers are filled with
high grade lithium based grease and rollers are sealed
for life, thus saving high maintenance cost during
life of roller.
ACCESSORIES For Impact Idlers specially designed soft rubber
rings are fitted to absorb impact at loading and transfer
points.
Also manufacture special rubber lagged rollers or
PVC lined rollers for handling corrosive material.
Special rubber rings are provided for self cleaning
rollers.
SILENT FEATURES :
* Confirms to IS:8531-1986.
* Each Pulley is designed according to its position
in conveyor, considering all tension parameters.
* Pulleys are statically balance.
* All components are standardized and compatible, hence
less cost.
DESIGN AND CONSTRUCTION : * Welded steel pulleys are of drum type, with rim,
end disc and hubs designed to give maximum rim overhang,
prevents accumulation of material.
* Smooth Pulley surfaces provide maximum belt protection.
* Hubs and end disc are accurately machined to assure
concentricity.
* Pulleys are available with straight or crowned face.
* Pulleys shafts are made from carbon steel/EN-8 and
are designed for torque and bending moment.
* Normally shafts are keyed in hub. However, taper lock
blushing for ease of maintenance can be provided. Shafts
are welded to pulley hub in case of light duty.
RUBBER LAGGING
* Drive pulley lagging is usually provided to increase
traction between belt and pulley.
* Snub and bend pulleys rubber lagging resists accumulation
of material on pulley surface.
* Rubber lagging of following types are available
1. Plain 2. Diamond 3. Herringbone
