Bucket Elevator Belt
Corrugated Side-Wall Belt
Pipe Belt
Pipe belt provides close transportation that can
avoid spillage and loss of bulk material to keep
environment neat; can prevent foreign matters
from mingling with or getting soaked by rain.
Transportation in a winding path.
Transportation at angles up to 30°.
Save space.
Can be used in various industries including
harbors, power stations, metallurgy, building
materials, bulk terminals, mining, cement,
paper-making etc.
Bucket elevator belt is designed for vertical
conveyance, and good for transporting materials
with powder and pellet, decreasing transporta-
tion distance .
It is suitable to be used in metallurgy, chemical,
building materials, mining, food, cement, feed,
crop oil etc.
Excellent design of cross rigidity and skirt part .
Corrugate side-wall belt can move material at
any angle of inclination with types of cleats and
height of the sidewalls. Saving the space and
length of conveyor system .
Save applied to harbors, metallurgy, mining,
power stations, foundry, building materials,
food, quarry, fertilizer etc.

Note : Rip stop steel cord conveyor belt need to consider warp strength. Rip stop steel cord conveyor belt also consider the belt speed, the environment, materials, the thickness of belt cover, width, ply number and other factors. The above specification reference in one single ply ( In the higher strength, speed, harsh environmen-tal conditions, the user need to consider in higher than specifications of 650 )

IW Steel Mesh Conveyor Belt
Advantages of steel mesh carcassHeat resistance Allowance of small pulleys Good troughability Impact resistance
Rip & tear resistance
Excellent adhesionbetween covers and carcass
Constructure of IW steel mesh
HYC IW steel mesh conveyor belt is constructed from high quality woven steel cord fabric with steel cord in longitudinal and transversal direction fixed together in 1 ply as carcass and special rubber compound to provide excellent impact and tear resistance, as well as thermal stability.
ApplicationRequirement for impact resistance:
mining, quarry, harbors……
Requirement for rip resistance:
metallurgy, mining, quarry, harbors……
Requirement for heat resistance:
metallurgy, cement, chemical……
Requirement for flexibility:
small pulley, bucket elevator
Steel warpThe longitudinal steel cables provide for both a limited elongation and a resistance to the compressive effects of impacts on the belt.
Steel weftThe weft is composed of high elongation thin steel wires compared to conventional steel-cord belts. It offers superior impact resistance, tear resistance, and good troughability.
Straight warp and weftIW steel mesh is built from woven steel cord fabric with steel cord in longitudinal and transversal direction fixed together in 1 ply.
