What is Portable Impact Crushing Plant?

The mobile primary impact crusher and inclined screen plant is a portable unit which consists of feed hopper, grizzly feeder and primary impact crusher and screen on the same trailer chassis. One deck screen can be added to grizzly feeder as an option to remove the fine material. They are complete processing plants with high reduction ratios used for the production of 2-3 sizes of aggregate or sub-base.

Types of Portable Impact Crushing Plants

The portable primary impact crusher and screen plant is a single portable unit capable of producing 2 -3 products where the crusher works in closed circuit with the screen.

How Does Portable Impact Crushing Plants Work?

Sizes bigger than the grizzly opening of the feeder in the feed materail enters the crushing chamber of the crusher and is crushed by the impact of the blowbars on the rotor of the crusher and by hitting the breaker plates opposite of rotor. The crushed material is sent to the screen to classify the product and the oversize is returned to the crusher for further size reduction.

Advantages of Using Portable Impact Crushing Plants

In addition to the general advantages of the impact crusher like high capacity, cubical end products in the primary stage, the advantages of being portable are as follows;

Compact design: Possibility to produce 2-3 finished products with a single unit.
Ready for operation: Can be commissioned and started up quickly.
No concrete works: No need for much concrete and site preparation.
