B Series Deep Rotor Vertical Shaft Impact Crusher

B Deep Rotor Vertical Shaft Impact Crusher

B Series Deep Rotor VSI Crusher is a new generation and high effective product which introduces German technology, and owns many independent patent properties. It integrates three crushing methods into one. All of these made it the core equipment in sand making industries. It is widely used in a variety of metallic and non-metallic minerals, cement, refractories, abrasives, glass raw materials, construction aggregate, sand, metallurgical and other industries.

Working Principle

Material falls down to impeller cavity. Under great centrifugal force, it hits material that is flowing around the impeller as an umbel. After hitting each other, they force a vortex between impeller and shell and hit each other for several times, and finally smaller stone comes out and forms closed cycle. The required end product shape is controlled by the screen equipment.

Features

  • 1. Deep cavity-type rotor design is optimized to increase material pass-through volume by 30%.
  • 2. Modular-design hammer, just to replace worn parts when wear out, it can reduce cost more than 30%.
  • 3. The core abrasion-resistant material is high degree wear-resistant and temperature-resistant material.
  • 4. Diamond-shaped impact block avoids stand plate being damaged after wear out.
  • 5. Bearing use Swedish and American international brand.
  • 6. Optimal shooting mouth and more fluid curve-shaped design reduce the resistance to the material flow, improving material pass-through capacity as well.
  • 7. Special seal structure in the spindle end, ensure no oil leak even without oil seal.
  • 8. Hydraulic openings device uses Japan imported parts, it is easy and quick to move upper lid, so the internal mechanical overhaul and replacement cost less labor effort.
  • 9. Uses high protection motor, which features high efficiency and low noise.

Safety

Safety is also a key element in the VSI crusher’s design and a hydraulically operated arm, called the “Hydra-Arm”, is available as an option on the machine, to lift and rotate the crusher lid, allowing safe and unobstructed access to the crushing chamber for maintenance. Bolt-on wear liners protect the tub and lid surface, for long service life, and allowing safe and easy maintenance with no welding required.
