The motorized drum is a compact and efficient power transmission component designed specifically for belt Conveyor Systems. Acting as the core driving element, the drum converts electrical energy into mechanical motion, transmitting torque directly to the Conveyor Belt through friction between the drum surface and the belt. Compared with traditional drive systems that rely on multiple external components, the motorized drum integrates power transmission, structural stability, and operational reliability into a single, highly efficient unit.
Motorized drums are widely used in bulk material handling, mining, ports, cement plants, metallurgy, logistics systems, and various industrial conveying applications. Their simple structure, stable performance, and long service life make them an ideal choice for modern conveyor systems requiring continuous operation and minimal maintenance.
In a conveyor system, the drum is the primary component responsible for transferring driving force to the belt. The rotational motion of the drum generates frictional traction that moves the belt and transports materials along the conveyor path. The effectiveness of this power transmission depends on the drum surface condition, shaft strength, bearing stability, and overall structural design.
Motorized drums are engineered to provide consistent torque output and smooth rotation, ensuring reliable belt movement even under varying loads and operating conditions.

To meet different operational requirements, motorized drums are available in multiple surface types.
Smooth drums are suitable for dry, clean conveying environments where belt tension and load conditions remain stable. They offer low resistance and efficient operation for general-purpose conveyors.
Rubber lagging enhances friction between the drum and the belt, improving traction and reducing the risk of belt slippage. This option is particularly effective in wet, dusty, or high-load environments.
Rubber lagging patterns include:
Smooth Rubber Lagging – Balanced friction for standard applications
Chevron (Herringbone) Rubber Lagging – Improved grip and drainage in wet conditions
Diamond Rubber Lagging – Maximum traction for heavy-duty or high-torque conveyors
Each lagging type is selected based on material characteristics, environmental conditions, and conveyor design.
Motorized drums feature a welded steel drum shell that provides excellent structural integrity and load-bearing capacity. The shell is manufactured using precision welding techniques to ensure uniform thickness and balance.
The drum shaft is made from high-strength 45# carbon steel, offering excellent torsional strength and fatigue resistance. This ensures stable power transmission even under heavy-duty operation.
All products use an integrated bearing housing design, which improves alignment accuracy and reduces vibration during operation. Bearing housings are available in cast iron or cast steel, allowing selection based on load requirements and operating conditions.
The bearing system plays a critical role in the service life of a motorized drum. High-quality rolling bearings are installed within the integrated bearing housing and lubricated with premium grease.
This grease-lubricated design minimizes friction, reduces heat generation, and protects bearings from dust and moisture. Under normal operating conditions, the motorized drum can achieve 3–5 years of maintenance-free operation, significantly reducing maintenance costs and downtime.

Commonly used in coal handling and ash conveying systems.
Suitable for automated material transport in factories and warehouses.

Proper installation is essential for optimal performance. The drum must be aligned accurately with the conveyor centerline to ensure even belt contact. Shaft ends should be mounted securely in bearing supports, and belt tension should be adjusted according to design specifications.
Rubber lagged drums require correct belt tension to maximize friction without causing excessive wear.
Before commissioning, inspect bearing lubrication, drum alignment, and belt condition. During operation, monitor noise, vibration, and temperature. Avoid overloading the conveyor or operating beyond rated parameters.
The motorized drum operates automatically without manual adjustment during normal use.
Thanks to the integrated bearing housing and grease lubrication system, maintenance requirements are minimal. Periodic visual inspections and routine checks are sufficient to ensure long-term reliability.
With correct selection and operation, the motorized drum can operate maintenance-free for 3–5 years under normal working conditions.
Belt Slippage
May be caused by worn rubber lagging or insufficient belt tension.
Abnormal Noise
Often indicates bearing wear or misalignment.
Uneven Surface Wear
Usually results from belt misalignment or improper installation.
When selecting a motorized drum, consider conveyor length, belt width, material characteristics, required torque, and environmental conditions. Rubber lagging type and bearing housing material should be selected according to load and operating environment.
Professional selection ensures optimal performance and long service life.
