FUNCTION ON A CONVEYOR BELT
A head pulley sets the conveyor belt in motion. A geared motor will be installed on the head pulley to control the force required to move the conveyor belt. As the conveyor’s key component, the head pulley is subjected to the greatest stresses due to the torque of the geared motor and the tension of the belt. On a set, it’s the most massive, and it’s particularly important to size the set correctly.
DIFFERENT NAMES FOR THE HEAD PULLEY
The head pulley, also known as the motor drum or drive pulley supports the conveyor’s geared motor. Because of this key function, it is sometimes also referred to as the drive pulley, as it controls the movement of the belt. Finally, if it is positioned at the top of the conveyor, it may be called the head drum.
Implementation
To ensure the belt is centered on the conveyor, the head pulley is curved. This profile aligns the belt while the conveyor is running.

Lagging for handling drums
In most cases, the drive or motor drum is lined with diamond rubber or ceramic lining to increase belt adhesion. Conveyor drive depends on belt adhesion. It’s therefore important to pay close attention to this item. ALTEMA’s teams are at your disposal to help you choose the best suited lagging to your needs.
