How Does a Radial Stacker Work?

A radial stacker is a versatile piece of equipment used in material handling operations to create large stockpiles of bulk materials. It is designed to move in a radial arc around a central pivot point, which allows it to distribute materials in a controlled and efficient manner, creating a conical-shaped stockpile. Here's a detailed explanation of how a radial stacker works:

1. Bulk Material Loading

Bulk material is loaded onto the conveyor belt of radial stacker, typically from a feed hopper, crusher, or another conveyor system.

2. Conveyor Belt Movement

The conveyor belt, driven by motors, transports the material along the length of the radial stacker boom to the discharge point.

3. Radial Movement

• The stacker boom rotates around the central pivot point in a radial arc. This movement is driven by the rotational mechanism (slewing ring, turntable, radial undercarriage).
• The radial motion allows the stacker to deposit material over a wide area, creating a large conical-shaped stockpile.

4. Adjustable Height

• Many radial stackers feature adjustable booms that can be raised or lowered. This helps control the height of the stockpile and ensures even distribution of materials.
• Adjusting the boom height can also help manage dust and material segregation.
• The radial stacker conveyor boom can be extendable. This design will increase the piling height and piling area. The radial stacker can be retracted for transport on site or on the road.

5. Stockpile Formation

• By continuously moving in a radial arc and adjusting the boom height, the stacker efficiently builds a stockpile in layers, ensuring maximum use of the available space.
• Operators can control the stacker's movement and positioning to create uniform, stable piles.

6. Mobility

The stacker can be repositioned as needed, either along tracks or wheels. This mobility allows it to service multiple stockpile locations or move to different parts of a site.

Radial stackers are integral to efficient material handling operations, offering the ability to create large, uniform stockpiles with minimal manual intervention. Their mobility, flexibility, and automation capabilities make them indispensable in industries that handle bulk materials, ensuring operational efficiency, cost savings, and improved safety.
