Powered Package Handling Conveyor

To facilitate the flow of packages and other relatively small items, belt conveyor and roller conveyor are well suited and able to cater to the needs.




What is a belt conveyor?
A belt conveyor runs on two end pulleys and it has a continuous loop of material that rotates around it. It usually consists of two layers of material. The under layer which is known as carcass provides the strength to start and move the loaded belt, while the over layer is called a cover which protects the carcass from any damage.

Belt conveyor comes in many varieties and the most popular and common ones are flat belt conveyor, trough belt conveyor and magnetic belt conveyor.


1. Flat Belt Conveyor
It is normally used for carrying unit light and medium weight loads like bottles, boxes, or other packaged materials between operations, departments and floors. The friction between the belt and the load is able to adjust the goods into the right place on the conveyor without some unnecessary bumps. It also avoids smooth accumulation, merging and sorting on the belt. It is suitable when an incline or decline is included in the conveyor path and the adjustable angle belt conveyor can also be used.

2. Troughed Belt Conveyor


It is an efficient means to transport bulk materials such as concrete, ore and coal. They are built to contain the items on the belt without spilling over the edges. Trough angle selection of 20, 35 or 45 degrees should be adjusted with the flow characteristics of the product.

3. Magnetic Belt Conveyor

The belt consists of a magnetic slider bed or magnetic pulley which will help to attract the ferrous objects to the belt and overcome any angle of incline or decline. With the help of magnetic forces, the ferrous materials can be moved vertically, upside down and around corners.



Roller conveyor
Roller conveyors are suitable for accumulating loads, merging and sorting of materials. It can be categorized into four main types as shown below.

1. Line shaft conveyor
The conveyor is powered by a drive shaft running under the rollers with O-rings connecting the shaft to the rollers. When the motor turns the shaft, the shaft turns the rollers.

2. Chain-driven roller
The conveyor is designed with two sprockets welded to the end of the rollers connected to a chain under the roller bed. When the motor moves the chain, the chain moves the rollers.

3. Belt-driven roller
The conveyor is driven by a belt running under the top rollers. Similarly, when the motor moves the belt, the belt moves the rollers.

4. Motorized roller
Motorized conveyor is divided into small zones, and the rollers at each zone are connected by O-ring. The internal motor that is installed in at least one roller of each zone will turn the motorized roller and the other rollers in the same zone as well.
