Application Versatility

Jaw Crushers applies compressive force onto material to be crush that may produces flakiness to the material. Flakiness is not permissible after certain extent because it reduces the strength of the material. Maxwell VSI intakes the screened material of specified size into the rotor where it is accelerated to high speed. The Material gets high velocity into the rotor and then it discharge from fixed rotor openings and collide with the rocked outer periphery resulting into crushing. Maxwell VSI crushers offers multi-port rotor designs that provide large application range and crushing technology for rock-on-rock reduction. Maxwell VSI can operate on high rotor speed which provides high crushing ratio. Such high crushing ratio enable Maxwell VSI to produce crush send as well.

High Adaptability

The design of this machine is very users friendly. The maintenance of this machine is very easy. Any unskilled person with average competency  can maintain this machine. All parts are very ergonomically designed which avoids any miss fitment.

Trouble free working

Single Point, Centralized greasing system ensures trouble free working. Easy to inspect rotor parts enables operator to ensure the maintenance schedule.

High Performance, Low Cost

Maxwell VSI offers efficient rock on rock reduction that is cost effective due to low wear. All wear parts are made of higher wear resistible steel and easily replaceable that reduces downtime and ultimately reduces operating cost. The optimized design results in low cost spares as compare to other manufacturers.

Description

Vertical Shaft Impactor (VSI) is a type of crusher that is used to reduce the size of rocks and other materials to create aggregates and other construction materials. It is widely used in the mining and construction industries for its high efficiency and productivity. In this article, we will discuss the basics of VSI and its working principle, along with its advantages and types.

VSI is a machine that uses velocity to crush rocks into smaller sizes. VSI Stands for Vertical Shaft Impactor. The material to be crushed is fed into the center of the rotor, which then throws it outwards towards the rock chamber walls. The material collides with the rock chamber walls and breaks into smaller pieces. The material then falls down to the bottom of the crushing chamber.

VSI has a unique design that allows it to produce high-quality aggregates with reduced flakiness. The machine is designed to handle hard and abrasive materials, making it suitable for a wide range of applications.

VSI is made up of several components, including the rotor, rock chamber, shaft assembly, and feed tube. The rotor is the heart of the machine and is responsible for throwing the material outwards towards the rock chamber walls. The Rock Chamber is gradually developed by collecting the rocks coming out of the rotor. Every particle that exists the rotor collide with the rock chamber walls and to the rotating rotor until it gets down due to gravity. The feed tube is responsible for guiding the material into the rotor.

VSI is available in different designs and configurations, each with its own set of advantages and disadvantages. Some of the popular designs include open and closed rotor with rock-on-rock, and rock-on-steel. 

Open rotor VSI is a type of VSI that has an open rotor design, which allows larger feed size. The design is ideal for larger feed sizes and high capacity requirements. Closed rotor VSI, on the other hand, has a closed rotor design that limits the amount of material that can enter the rotor. The design is ideal for smaller feed sizes and finer products.

Rock-on-rock VSI is a type of VSI that uses the material itself to break down feed materials. The material is thrown against itself and the surrounding rock chamber wall (gradually developed on the outer side), which break it down into smaller pieces. The design is ideal for high abrasion material and high fines content. Rock-on-steel VSI, on the other hand, uses steel anvils to break down the material. The design is ideal for medium to high abrasion materials with high reduction ration. Among all Closed Rotor with rock-on-rock configuration is highly popular due to low operating costs.   

VSI has several advantages over other types of crushers. It has a high crushing ratio, which means it can produce more fine materials with less wear and tear on the machine. VSI is also simple and easy to operate, making it an ideal choice for many industries.

In conclusion, VSI is a versatile and efficient machine that is widely used in the mining and construction industries. It has a unique design that allows it to produce high-quality aggregates with reduced flakiness. VSI is available in different designs and configurations, each with its own set of advantages and disadvantages. VSI is very versatile machine making it an ideal choice for many industries.
