Tertiary Crusher

What is a Tertiary Crusher?

Before understanding the tertiary crusher, it is important to first know what crushers are. Crushers are machines designed to reduce the size of larger materials by applying force to break them down into smaller and more compact pieces. This can be done by compacting the mass or by using force to break the material into smaller fragments.

A tertiary crusher is used in crushing plants after secondary crushers, particularly for processing limestone, alluvium, and quarry materials. It works by applying high-speed impact to the material. The distance between the crusher rod pendulum and the rotor can be easily adjusted using a bolt, allowing for the production of materials in the desired size.

Working Principle of a Tertiary Crusher

Tertiary crushers operate on the principle of applying high-speed impact to the material through reversible breakers. These machines produce cube-shaped (cubic) material by throwing the material onto fixed counter pallets using a rotating rotor. The design of the rotor and crusher pallets ensures the efficient production of thin, high-quality materials. Tertiary crushers are known for their durability and low operating costs, making them ideal for long-term use.

Tertiary Crusher Characteristics

Tertiary crushers are divided into two main types:

1. Horizontal Rotor Impact Crusher
2. Vertical Shaft Impact Crusher

• Horizontal Rotor Crushers are specialized for breaking quarry materials, alluvium, and limestone. The material is impacted at high speed, causing it to break apart as it is thrown against the lining on the pendulums by means of crusher pallets. These crushers are suitable for softer materials like limestone and alluvium, as well as for harder stones like basalt and granite.
• Vertical Shaft Impact Crushers are designed for harder and more abrasive stones. The high-speed rotor throws the material against impact wedges, resulting in both low sand production and high sand yield.

Key Features of Tertiary Crushers:

• Adjustable Design: The distance between the rotor and the crusher rod pendulum can be adjusted to produce material of varying sizes.
• Reversible Rotor and Pallets: The rotor can rotate in both directions, increasing the lifespan of the pallets and improving the efficiency of material processing.
• High-Speed Impact: The high-speed rotor ensures maximum impact on the material, improving the quality of the final product.
• Easy Maintenance: Moving bodies on both sides can be fully opened, simplifying maintenance and part replacement.
• Versatile Applications: Tertiary crushers are suitable for use in concrete batching plants and asphalt plants, producing sand and materials in the required sizes.
