An 80 secondary crusher is a machine used in quarries, mining, and recycling industries to break down medium-sized stones into smaller pieces. The term "secondary" means that it is used in the second stage of the crushing process. It processes large stones that have already been crushed by a primary crusher and reduces them to smaller sizes for use in construction, concrete, and asphalt production.

Key Features and Advantages:

Processes Medium-Sized Material: Works with stones ranging from 200-400 mm.
High Capacity: Can crush approximately 80 tons per hour.
Impact or Cone Crushing Mechanism: Can use impact crushers or cone crushers, depending on material type.
Uniform Product Output: Produces evenly sized aggregates.
Low Maintenance Costs: Built with wear-resistant parts for durability.
Versatile Applications: Used in construction, road building, concrete production, and filling materials.

Working Principle:

Medium-sized rocks from the primary crusher are fed into the hopper.
The rotor or cone crushing system spins at high speed, breaking or compressing the material.
 The crushed material is screened to obtain the desired size.
The final product is ready for concrete, asphalt, and filling material production.
