McLanahan Feeder-Breakers

McLanahan Feeder-Breakers

Heavy-Duty Feeding and Primary Crushing in One Machine

McLanahan Feeder-Breakers combine the functions of a feeder and primary crusher into a single machine, providing a reliable solution for reducing large volumes of ROM (Run-of-Mine) material to a controlled size for downstream processing.

Designed for demanding mining applications, Feeder-Breakers can receive large, irregular feed directly from haul trucks, loaders or other mining equipment while controlling the material flow and reducing its size in a single operation.

This combination can simplify the material handling circuit, reduce the number of individual machines required and provide a compact solution for primary crushing.

How McLanahan Feeder-Breakers Work

Material is loaded into the Feeder-Breaker's hopper or receiving area.

The feeder section controls and regulates the flow of material toward the crushing mechanism. As the material moves through the machine, the breaker mechanism engages the larger pieces and reduces them to the required size.

The integrated feeding and crushing action provides a controlled material flow while preventing oversized material from entering the downstream conveying or processing system.

Depending on the model and application, Feeder-Breakers can be configured with different breaker roll designs, tooth configurations and product-size settings.

Feeding and Crushing in One Machine

A major advantage of the Feeder-Breaker is the integration of two functions into one machine:

Feeding + Primary Crushing

The feeder controls the rate at which material enters the crushing zone, while the breaker reduces the material to the required top size.

This can eliminate the need for a separate primary feeder and crusher in suitable applications, helping to reduce equipment count, footprint and material transfer points.

Controlled Product Size

The breaker section is designed to reduce oversize material while allowing appropriately sized material to pass through the machine.

Product size can be influenced by the breaker configuration, tooth arrangement, breaker setting and material characteristics.

The appropriate product size should be selected according to the requirements of the downstream conveyor, screen or processing equipment.

Handling Large ROM Material

McLanahan Feeder-Breakers are designed for applications where the feed material may contain large, irregular pieces.

Their robust construction and high-torque crushing action allow them to handle demanding primary crushing duties while maintaining controlled material flow.

This makes them particularly suitable for mine-site applications where material is delivered directly from excavation or blasting operations.

Low-Profile Design

Feeder-Breakers can be configured in low-profile arrangements, making them suitable for underground mining and other installations where available height is restricted.

Their compact configuration can also simplify integration with conveyors and other material-handling equipment.

Applications

McLanahan Feeder-Breakers are used in a variety of mining and material-handling applications, including:

• Coal mining

• Underground mining

• Surface mining

• ROM coal handling

• Mineral processing

• Aggregate applications

• Primary crushing

• Material transfer systems

Typical materials may include:

• Coal

• Salt

• Gypsum

• Potash

• Limestone

• Soft and medium-hard minerals

• Other suitable friable materials

Application suitability depends on the material's hardness, abrasiveness, moisture, feed size and other characteristics.
