Structural Composition of the TD75 Conveyor System

The TD75 conveyor system consists of multiple standardized components working together to form a robust and reliable conveying solution.

Conveyor Structure and Frame

The conveyor structure provides mechanical support for the entire system. It is typically constructed from carbon steel profiles designed to withstand heavy static and dynamic loads. Depending on installation requirements, the structure may be ground-mounted, elevated, or supported by steel trestles.

The standardized frame design ensures consistent strength while allowing flexibility in conveyor length and layout.

Conveyor Belt

The conveyor belt is the primary load-carrying component. TD75 systems commonly use:

EP (polyester-nylon) conveyor belts
NN (nylon-nylon) conveyor belts
steel cord conveyor belts for long distances or high tension

Belt selection depends on material type, conveying distance, capacity, and operating conditions such as temperature and abrasiveness.

Drive System

The drive system supplies the power required to move the belt and transported material. It typically includes:

Electric motor
Gear reducer
Coupling
Drive pulley

For long or high-capacity conveyors, multiple drive units may be installed to distribute load and reduce belt tension.

Pulleys

Pulleys guide and drive the conveyor belt. In the TD75 system, common pulley types include:

Drive pulleys
Tail pulleys
Bend pulleys
Snub pulleys

Pulleys are often rubber-lagged to improve friction, reduce slippage, and extend belt life.

Idler Assemblies

Idlers support the belt and help form the material-carrying profile. TD75 conveyors use standardized idler sets, including:

Trough idlers
Impact idlers at loading points
Return idlers
Self-aligning idlers

Proper idler configuration ensures smooth belt operation and reduced energy consumption.

Take-Up Device

The take-up device maintains proper belt tension. TD75 systems commonly use gravity take-up or screw take-up mechanisms, depending on conveyor length and load.
