A VSI (Vertical Shaft Impact) crusher is designed to produce high-quality, cubical-shaped aggregate from various types of materials. Its main components include:
A jaw crusher primarily consists of:
Rotor: The central rotating element of the VSI crusher that accelerates the material to high speeds.
Impactor: Located around the rotor, it imparts high-velocity impact on the material.
Cavity: The area where the material is accelerated and impacted to break it into smaller pieces.
Feed Hopper: The entry point where the material is fed into the crusher.
Discharge Port: The exit point where the crushed material is ejected.
Frame: The structural support for all components, often made from robust steel.
Fixed Jaw Plate: A stationary component mounted on the machine frame, usually made of durable cast steel.
Movable Jaw Plate: A component that moves back and forth, connected to a hinge mechanism.
Jaw Plate Support: Structures that support and secure the jaw plates, ensuring stability and durability.
Eccentric Shaft: Transfers power to the movable jaw plate, typically driven by an electric motor.
Flywheel: Stores and releases energy to help reduce vibration.
Base and Frame: The support structure for the entire machine, bearing all working components.
The VSI crusher operates on the principle of high-speed impact. The working process involves:
Jaw crushers operate based on compression and impact. The process includes:
Feeding: Material is fed into the rotor from the feed hopper.
Impact: The accelerated material is projected towards the impact plates or anvils where it is crushed by high-velocity impacts.
Feeding: Material enters the crusher through the feed opening.
Crushing: The movable jaw plate compresses the material between itself and the fixed jaw plate, breaking it down.
rushing Stage: Used primarily for shaping and fine crushing.
Applicable Material Hardness: Suitable for materials with high abrasiveness and hardness, including rocks and minerals with compressive strengths above 150 MPa.
Crushing Ratio: Typically around 4:1 to 8:1, depending on the material and application.
Feed Size: Maximum feed size generally ranges from 30 mm to 100 mm, depending on the model.
Output Size: Output sizes can be adjusted, usually ranging from 0.075 mm to 30 mm.
Output Particle Shape: Produces cubical or angular particles with consistent shape.
Production Capacity: Generally ranges from 30 t/h to 600 t/h, depending on the machine size and configuration.
rushing Stage: Primarily used for primary crushing.
Applicable Material Hardness: Suitable for materials with compressive strength between 150 to 300 MPa.
Crushing Ratio: Typically ranges from 6:1 to 10:1.
Feed Size: Maximum feed size ranges from 150 mm to 1500 mm.
Output Size: Discharge size is adjustable, generally from 10 mm to 300 mm.
Output Particle Shape: Typically irregular due to the compression mechanism; particles may be cuboidal, rectangular, or irregular.
Production Capacity: Generally ranges from 20 t/h to 1500 t/h.
High Cubical Shaped Product: Produces high-quality, cubical-shaped aggregate.
