McLanahan Jaw Crushers

McLanahan Jaw Crushers

Reliable Primary Crushing for Mining, Aggregates and Mineral Processing

McLanahan Jaw Crushers are robust primary crushers designed to reduce large, hard and abrasive materials into a manageable size for downstream processing.

Jaw Crushers use a simple compression crushing principle, making them well suited for a wide range of mining, quarrying, aggregate and mineral processing applications. Their rugged construction and reliable operation make them suitable for demanding operating environments where high reduction and dependable performance are required.

How McLanahan Jaw Crushers Work

A Jaw Crusher consists of two crushing surfaces: a stationary jaw and a moving jaw.

Material is introduced through the top of the crushing chamber. As the moving jaw moves toward the stationary jaw, the material is compressed and fractured.

When the moving jaw moves away from the stationary jaw, the crushed material moves downward through the crushing chamber. Once the material reaches a size smaller than the discharge opening, it exits from the bottom of the crusher.

This repeated compression cycle continues as new material enters the crushing chamber.

Primary Crushing

Jaw Crushers are commonly used as the first stage of size reduction in a crushing circuit.

They are capable of accepting relatively large feed material and reducing it to a size suitable for secondary crushing, screening or other downstream processing equipment.

The final product size is primarily influenced by the crusher setting, feed characteristics and operating conditions.

Crusher Setting

The discharge opening, commonly referred to as the Closed-Side Setting (CSS), is one of the main factors controlling the size of the crushed product.

Reducing the CSS generally produces a finer product, while increasing the CSS produces a coarser product and can increase the crusher's capacity.

The appropriate setting should be selected according to the required product size, feed characteristics and overall crushing circuit.

Heavy-Duty Construction

McLanahan Jaw Crushers are designed for demanding applications and can be configured to handle hard and abrasive materials.

Key components are engineered to withstand the high forces generated during crushing, while replaceable wear components help protect the crusher and simplify maintenance.

Hydraulic Adjustment and Protection

Depending on the model and configuration, McLanahan Jaw Crushers can incorporate hydraulic systems for crusher adjustment and overload protection.

These systems can allow the operator to adjust the crusher setting and provide protection when uncrushable material enters the crushing chamber.

Hydraulic features can also help simplify maintenance and improve operational flexibility.

The appropriate Jaw Crusher should be selected based on the complete application requirements, including:

• Material type

• Maximum feed size

• Required product size

• Required capacity (TPH)

• Material hardness

• Abrasiveness

• Moisture content

• Required reduction ratio

• Primary crushing duty

• Installation arrangement
