Impact crushers play an integral role in the aggregate industry. This includes the processing of a number of materials, from cement, concrete, asphalt,or crushed stone, to sand & gravel. These various elements are broken down into a salable product as efficiently and inexpensively as possible. Utilizing this machinery allows a site to break up the various materials in a number of ways. With a range of offers to suit a collection of needs, there are many ways to process and refine ideally. Read on to learn more.
Their Role
These heavy duty pieces of equipment may be used as primary, secondary, or tertiary elements of the process, depending on the required final result and size requirement. These machines are available in many forms, from stationary and track based, to more portable configurations. These offerings ensure you can meet any demand across a range of industries. Although impact crushers generally have a higher operating cost than other alternatives, they also tend to produce a much more uniform shape as a result. This ensures a high quality and more desirable material, especially for industry like asphalt production. Common types of machines on offer are horizontal shaft impactors and vertical shaft impactors. While they produce the same end results for the most part, the mechanisms they use are what duffers.
Horizontal Shaft Impactors (HSI)
This range consists of designs around a hopper, two or three aprons, a rotor, and hammers, all of which work to guide, funnel and breakdown the material. What happens in operation is large chunks of material are fed into the hopper where they come into contact with hammers on a spinning rotor. This in turn crushes the material into smaller pieces. As the material gets hit repeatedly by the hammers, it comes into contact with the aprons which then rebound it back towards the hammers. This is repeated until the correct sizing is achieved and the final product is discharged.
Vertical Shaft Impactors (VSI)
This machine on the other hand consists of a feed hopper, feed tube, a rotor, and either stationary anvils or rock shelves. What happens in this process is that the material is fed through the feed tube into the rotor, which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys or rock shelves. This focuses on using the natural stress lines of the rocks to break it apart by force. The final result is a cubical product. This method is both economical and simple to operate.
