Vertical Shaft Impactor : First choice for chipping and sand production
The Multirok® vertical shaft impactor (VSI) is used for tertiary and quaternary crushing to produce chippings and sands with high portions of cubical product. Depending on the application, customers have the choice between open and closed rotors as well as rock-on-anvil and rock-on-rock crushing. Regardless of the crusher configuration, crushing tools made of high performance materials ensure longest service life.
An Ideal Tertiary Machine for
- Concrete Aggregates
- Manufactured Sand
- Asphalt Mixing
- Road Base Materials
- Easy portabiity and quick insta•aticn With
- minimum support Structures.
- Variable capacity rnodds for tertiary
- Rack-or—Roch technology minimizes
- wearing cf parts, hence rmmimum
- operating and wear costs.
- Excelent cubicle shape product.
- Consistent product gradation.
- Simple maintenance.
- Quicker realacerr,ent of worn out parts –
- lesser dmvntime.
- Retr04t for conversion to Rock—co-Steel
- ior less abrasive rocks
RETRO-FITS FOR ROCK-ON-STEEL
Tkll offers anvil rings and rock box
combinations to convert the Rock-on-Rock to
Rock-on-Steel models for lesser abrasive
rocks to get higher product yield. The retro-
fits can be quickly installed in the existing
Rock-on-Rock models with minimum
changes in the machine, which can be
conveniently done at site. The retro-fits give
the flexibility to change-over between Rock-
on-Rock and Rock-on-Steel applications to
meet the differing product needs.
HOW IT WORKS
The mechamsm Invobed is verv simde. The
rock to be crushed is fed through the hopper
and e feed tube onto the center Of a dosed
rotor. The rotor spinning at high speed throws
the material with a great centrifugal force.
When the accelerated rock hits the stationary
rock-box, known as Rock-on-Rock High
Performance princide, it breaks by impact
along the natural fault lines resulting in a
cubical shaped product, which falls freely by
gravity on to a conveyor belt below.
The Rock-on-Rock principle simulates the
nature’s way cf impact and grinding that
occurs in generation Of particle shape in
The VSI crusher thus comes out a winner as
producer cf quality aggregates as as
Manufactured Sand, which is very close to
the natural sand in partide shape and
