What is a Tertiary Impact Crusher and Where is it Used?

A tertiary impact crusher is a type of crusher used in the mining and construction industries to break down materials into smaller, more manageable sizes. It is specifically designed for the third stage of crushing, following primary and secondary crushers. Tertiary impact crushers are known for their high reduction ratios and ability to produce finely crushed materials with a cubic shape, making them ideal for producing high-quality aggregates.

How it Works:
The crusher uses high-speed impact forces to break down materials. Rocks or other materials are fed into the crusher, where they collide with hammers or blow bars rotating at high speeds. This impact shatters the material into smaller pieces, which are then discharged through adjustable grates or screens.

Applications:

  • Production of fine aggregates for concrete and asphalt.

  • Recycling of construction and demolition waste.

  • Crushing of soft to medium-hard materials like limestone, dolomite, and gypsum.

  • Mining operations where finely crushed materials are required.
