Vertical Shaft Impactors
For over 16 years, our company is successfully engaged in serving our clients by manufacturing and supplying a widespread range of Vertical Shaft Impactors. These machines play a vital crushing role in diverse industrial sectors such as metallurgical industry, mining industry and so-forth. Offered range of impactors are highly obliged for their efficiency, stable working and admirable performance. Additionally, these impactor machines are precisely engineered so that these can higher feed rate for crushing hard materials at rapid rate. We provide these Vertical Shaft Impactors in both customized and non-customized solutions to satisfy the needs of our valuable clients.

ALMEDIATM the leaders in Jaw Crushers Technology are proud to introduce the Vertical Shaft Impactors.
It is a next generation tertiary machine designed & manufactured with quality workmanship. Hence a robust & tertiary machine for concrete aggregates, sand manufacturing, asphalt mixing & materials for road base.
ALMEDIATM VSI - How it works
It works on the principle of centrifugal force. Material to be crushed is fed into center of the rotor, through a vertical tube. The Rotor rotates at high speed of 50-60 m/sec. Due to centrifugal force3 the feed material starts attaining speed & gets distributed over the distribution rock box. As the material reaches the rotor vanes, towards the periphery, attains the same speed as the speed of rotor's periphery. At the instant of leaving the rotor, material attains a velocity which is the resultant of peripheral Velocity & radial velocity due to centrifugal force. The direction of resultant velocity is almost 45o to radial direction.
The high velocity feed particles attain tremendous kinetic energy, so after impact against the breaking surface, stresses are developed within the particles & they disintegrate into number of pieces.
ALMEDIATM manufacture both types of VSI :
- ROCK - ON - ROCK
- ROCK - ON - STEEL
ROCK - ON - ROCK TYPE : Rotor is designed in such a manner that stone layer gets formed on the vane & breaking surface is also formed by material built up. This reduces wear & tear of both, vanes & breaker walls. The advantage of this type of VSI is that, spare consumption is reduced but the cushioned surfaces reduce considerably the amount of crushing.
ROCK - ON - STEEL TYPE : In the type material to be crushed glides on the steel vanes & after getting released from the rotor, strikes on steel surfaces. Although the wear & tear of vane surfaces & breaker surfaces is high, we can use bigger feed - size (upto 100mm) & the reduction ratio is also high.
