Eastman sand making machine series

rock on rock

Rock on rock crush
This is a rock on rock (autogenous) crusher, whereby no wear parts are used to crush the rock.

bearing seal structure

Bearing Sealed structure
The sealing structure prevents oil leakage and dust from entering the bearing barrel.

Stationary, mobile version
Mobile VSI sand making machine (wheel or crawler type) easily moves in different  applications.

VSI Maker was first manufactured by the German. Our factory adopted this advanced technology and made some improvement on its rotor structure. Now it is the fourth generation of high-performance sand making equipment with the great improvement and optimized design.
Simple open table and enclosed rotor designs provide reliable performance and low maintenance.

sand making machine application

Sand Making machine working principle

A VSI crusher is typically a third stage crusher (maixmum feed size if 55mm) and crushes rock by the impact of rock agianst rock. The vsi sand making machine works by accelerating rocks using centrifugal gorce, to a very high speed and then impacting them into each other within the crushing chamber.

VSI Crusher has min. wear and max. profits

A properly configured VIS is the key to reducing wear costs and downtime and maximizing profits.

  • The crushing cavity internal items can be changed or repaired easily and fast because of adopting hydraulic device.
  • With the unique feeding structure it is convenient to realize the ‘rock on rock” and “rock on ore”can crush and shaping stones.
  • Dustproof sealing system completely avoid the external dust into the lubricating parts.
  • High quality materials and advanced technology improve the equipment quality and performance.
  • The best design of crushing cavity prolong the service time of wearing parts and reduce the cost.
  • Feeding pipe of high abrasive alloy material has a long service life
  • Feeding distributor are made of high chromium iron wear resistant material high manganese steel plate
  • Enclosed rotor designs provide reliable performance and low maintenance.
  • Forged hardened and tempered chrome molybdenum steel, large diameters to suit heavy duty application.
  • Vertical bearing are produced by the largest manufacturer nationwide and they can support the upper part effectively.
