Components
Bulk material conveying systems, pipe conveyors, heavy-duty feeders and inspection equipment.
Drive and bend pulleys for transmitting power, changing belt direction and maintaining belt wrap.
Conveyor rollers, troughing sets, impact assemblies and nonmetal low-noise idlers.
Long-Distance Belt Conveyors
KDHI designs long-distance belt conveyor systems for bulk material routes linking mines, processing facilities and terminals.
Tubular Conveyor / Pipe Conveyor
KDHI pipe conveyors provide enclosed bulk material transport for ports, power plants, metallurgy, cement and mining applications.
Long-Distance Curved Belt Conveyors
KDHI designs long-distance belt conveyors with horizontal and vertical curves for bulk material routes across complex terrain.
Steep-Angle Belt Conveyors
KDHI designs steep-angle belt conveyors for uphill or downhill bulk material routes where space and elevation shape the layout.
Drive Pulley / Head Pulley
High quality ceramic coated, ceramic lagging drive pulleys, head rubber coated rollers and Lagging,Diamond shaped coated pulleys etc.
Bend Pulleys
Bend Pulley, Snub Pulley, Take-up Pulley, Tension Pulley, tail pulley, smooth surface pulley, etc
Heavy duty pulley
For high-capacity conveyors, we have specially designed heavy-duty pulleys, which have a more complex structure than conventional pulleys and greatly increase the strength of the pulleys,
Cage bend pulley
Installed at the tail section, take-up trolley and return bend positions of stacker-reclaimer.
Polymer roller / Nonmetal Low-Noise Idlers
KDHI's nonmetal low-noise idlers use modified ultra-high-molecular-weight polyethylene shells, low-noise deep-groove ball bearings and V-type contact sealing. The design addresses running noise, corrosion, material adhesion and roller weight.
Impact Idler Assemblies
Impact idler assemblies support conveyor belts at loading points, using resilient roller surfaces to accommodate material impact.
Troughing Idler Sets
Troughing idler sets support the loaded conveyor belt, using coordinated rollers and frames for bulk material transport.
Steel Conveyor Rollers
Steel conveyor rollers support the belt and bulk material, with bearing and sealing arrangements selected for conveyor duty.
Conveyor Control and Protection Systems
KDHI supplies centralized electrical control and protection systems for monitoring and operating belt conveyor lines from a control room.
Jupiter-1S Inspection Robot
The Jupiter-1S robot monitors conveyor rollers and belt condition, supporting inspection records and maintenance planning.
Heavy-Duty Belt Feeders
KDHI heavy-duty belt feeders introduce stored bulk material from bins or hoppers into conveying systems at a controlled rate.
Conveyor Steel Structures
KDHI designs and manufactures conveyor trusses, pulley and idler frames, support steelwork, access assemblies and rain covers.
