Introduction
WEARCO have over
40 years combined knowledge and experience in the field of
materials handling, engineering design and installation and
conveyor component selection and installation. WEARCO manufacture a comprehensive range of primary and secondary
belt cleaners/scrapers, return belt ploughs, belt training
devices and skirt containment systems.
IN THIS SECTION
Conveyor Idlers
WEARCO NSW supply
conveyor idlers, impact idlers and return belt idlers
assemblies, through such manufactures as DRC Rollers, Prok
Group, and Tyton Idlers, and Special roller
configurations.
WEARCO NSW supply
polymer rollers. These rollers are a new generation, heavy
duty alternative to steel rollers. The rollers are
constructed of glass-filled fibre, high density,
polyethylene (HDPE), which has proven to substantially
outlast steel rollers.
The significant
advantages which apply to applications utilising K-Poly
Conveyor Rollers are:
-
Less damage to
belting in event of roller collapse.
-
Noise reduction of
poly surface up to 9dba reduction over conventional
steel rollers.
-
Wear resistant.
-
Reduced material
build up upon roller shell.
-
Up to 50% lighter
than conventional idlers.
Belt Cleaning Systems
During the past twenty
years there has been significant improvements made in major
component design and efficiency of operation for belt
cleaning systems. WEARCO NSW has identified the need to
ensure high equipment availability is maintained with belt
cleaning systems which deliver an effective high percentage
of material carry back removal whilst maintaining a simple
approach to maintenance and accessibility.
WEARCO Head
Scraper WEARHEAD
WEARCO Head Pulley
conveyor belt cleaners are designed especially for the
high-cycle, high-speed vulcanized and clipped belts used in
the mining and quarry industry, coal-fired power
plants, coal loading facilities and coal preparation plants. The
WEARCO engineered WEARHEAD Scraper is designed to offer high
conveyor belt cleaning efficiency, reduced maintenance and
superior durability.
Urethane Blades. The
primary cleaner blades are constructed from 90 duro polyurethane
material for
increased blade life with an effective useable blade tip
depth of 60mm. The easy to see Coloured Built-in Blade Wear
Gauge ensures the active cleaning tip, which is colour-coded
orange, will make it easy to see when blade replacement is
required. The 200mm wide blade segments quickly conform to
the contours of the belt and maintain full blade-to-belt
contact for continuous cleaning through a mechanically adjusted
torque arm arrangement. Additionally, a spring
self tensioning arrangement can be adopted to suit all
models.
WEARCO Secondary
Scraper WEARSEC
WEARSEC Secondary
conveyor belt cleaners are designed especially for
high-speed vulcanized and clipped belts used in the mining
and quarry industry as well as coal-fired power plants, coal
loading facilities and coal preparation plants. The WEARCO
engineered WEARSEC Scraper is designed to offer high
conveyor belt cleaning efficiency and reduced maintenance.
The secondary cleaner
blades are constructed from 90 duro polyurethane material
for increased blade life with an
effective useable blade tip depth of 30mm. The easy to see
Coloured Built-in Blade Wear Gauge, which is colour-coded orange, will make it
easy to see when blade replacement is required. The 150mm
wide blade segments quickly conform to the contours of the
belt and maintain full blade-to-belt contact for continuous
cleaning through a mechanically adjusted torque arm
arrangement. Additionally, a spring self
tensioning arrangement can be adopted to suit all models.
The WEARCO Belt clear
assemblies are suitable for conveyor belt widths up to 1200mm
wide and belt speeds of 4.5 m/sec as standard design. For
applications where belt width or speeds are greater, our
qualified service representatives will inspect and provide
recommendations based upon the clients requirements.
WEARCO
Belt cleaners can be retrofitted in most cases to
existing structure and head chutes with minimal modification
to exiting plant. The life of WEARCO Poly blades will vary
upon the material being conveyed and moisture content
retained in the material. Similar the effectiveness of the
cleaners will vary upon moisture containment within the
material and surface condition of the belt.
WEARTUFF Return Belt
Ploughs
In many conveying
applications, material spillage which is carried back on the
top side of the return belt will pass between the tail
pulley and belting which causes excessive belt tracking
issues. Where large product lump size is evident, damage
through puncturing the belt can occur. Where
small dust material build up has occurred, this can increase
the diameter of the tail pulley and subsequently incur belt
tracking issues.
 WEARCO
have developed the WEARTUFF Plough arrangement to be
positioned prior to the tail pulley on the inside of the belt towards the direction
of belt travel. This arrangement will clean fine materials and remove larger
lump product. The plough has an adjustment turnbuckle
arrangement to reduce the potential of blades scalping the
belt.
WEARCO
Impact Cradle / Skirt Containment
The strongest and most
complete construction for installing Impact areas is to use a
Mounting Cradle. This replaces existing impact idlers. The
sides of the cradle are articulated, making the installation
of the system and replacement of worn-out impact bars and Impact idler assemblies
simple and quick. The belt edge is given the support
required to allow skirt sealing system to work in the
optimum way.
The side assemblies
are standard as a fixed angle to suit existing impact idler
replacement to the exact profile, however side assemblies can
be designed as an adjustable unit upon
request. 
Additionally WEARCO
have designed an improved curved saddle assembly which
incorporates either single block assemblies or full length
wear strips.
Conveyor Pulleys
WEARCO NSW supplies an
extensive range of drive and non-drive pulleys for
replacement or new capital project works. Shaft
configuration is either welded shaft or locking assembly
arrangement. Crowned, Flat and Self Cleaning styles are
available. Bearings supplied are plumber block type
housings and, unless otherwise required, sealing is
felt seal. Labyrinth and Tachonite seals are available.
  Pulley
lagging is selected based upon the application. As a general
rule, drive pulleys are a flat faced diamond pattern, Bend
Pulleys, GTU and Tail Pulleys are crowned with plain
lagging. Live shaft or dead shaft assemblies are available
and are selected based upon the application.
