Stacker

A stacker is a large machine used in bulk material handling applications. Its primary function is to stack bulk material such as limestone, ores, and cereals on to a stockpile. A stacker can typically move in at least two directions: horizontally along the rail and vertically by lifting its boom.

Types of Stackers

There are several types of stackers, each designed for specific applications and materials. The main types include:

• Portal Stackers: These stackers have a portal frame that straddles the stockpile and can move along the length of the pile.
• Bridge Stackers: These stackers have a bridge-like structure and are used for stacking materials in a linear fashion.
• Circular Stackers: These stackers are used for creating circular stockpiles and are often used in conjunction with reclaimers.

Components of a Stacker

A stacker typically consists of the following components:

• Boom: The long arm that extends from the stacker and is used to deposit material onto the stockpile.
• Conveyor Belt: A belt that transports the material from the source to the boom.
• Chassis: The base structure that supports the stacker and allows it to move along the rail.
• Control System: The electronic system that controls the movement and operation of the stacker.

Operation

Stackers are operated either manually or automatically. In manual operation, an operator controls the stacker from a control cabin or remotely. In automatic operation, the stacker is controlled by a computer system that uses sensors and algorithms to optimize the stacking process.

Applications

Stackers are used in various industries, including:

• Mining: For stacking ores and minerals.
• Cement: For stacking raw materials like limestone and clay.
• Power Generation: For stacking coal and other fuels.
• Agriculture: For stacking cereals and other bulk agricultural products.

Advantages

Using stackers in bulk material handling offers several advantages:

• Efficiency: Stackers can handle large volumes of material quickly and efficiently.
• Safety: Reduces the need for manual labor, thereby minimizing the risk of accidents.
• Cost-Effective: Reduces operational costs by automating the stacking process.
