The structural features of ore sand making machines mainly revolve around their vertical shaft impact design. The core of this design lies in achieving efficient sand making through a high-speed rotating rotor and a special crushing chamber. The following are its key structural features:
1. Core Structural Components
Feed Hopper: Material enters the equipment through this hopper.
Intermediate Chamber Liner and Crushing Chamber: These form the crushing space. The intermediate chamber liner is typically made of wear-resistant material.
Impeller (Rotor): The core component rotating at high speed. Material is subjected to centrifugal force and thrown out.
Main Motor and Transmission Device: Provides power to the equipment.
Vortex Crushing Chamber: Utilizing the stone-on-stone principle, material is crushed by impact within the chamber, reducing metal wear.
2. Key Structural Features
Vertical Shaft Impact Design: The mainstream structure, offering high crushing efficiency and good product particle shape.
Wear-Resistant Components: Impeller, distributor, impact liner, etc., are made of high-chromium wear-resistant material, ensuring a long service life.
Hydraulic cover opening device: Equipped on some newer models, facilitating maintenance and replacement of wear parts.
Double-sided inspection ports: Facilitate daily maintenance and inspection.
Dry oil lubrication system: The lower end of the spindle has a special sealing structure for easy maintenance.
