Portable Impact Crushing Plants
MEKA Portable Impact Crushing plants are wheel-mounted rock crushing machines, engineered to operate as a complete stand-alone closed-circuit unit with two or three products capability. Featuring the MGF type grizzly feeder, highly reliable and productive MPI Impactor for primary crushing, closed circuit belt conveyors for excellent feed to the MS type screen, it offers a highly versatile, highend capacity plant capable of processing cubical products at a low cost-per-tonne operation.
Applications
Portable Impact Crushing plants are an extremely versatile and economical unit and has proven it’s effectiveness in a host of missions like crushing soft and medium-hard materials such as limestone, low abrasive rocks, for quarrying, concrete and asphalt recycling and are the optimal choice if you want to move the crushing plant from one site to another periodically. They are easily transportable between production sites and often utilized in aggregates production and recycling applications.

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.

Advantages of Using Portable Impact Crushing Plants
Portable Impact Crushing Plants Processes Applications
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.
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.
Quick and easy site change for another project
Portable impact crusher and inclined screen combined plants are suitable for crushing soft to medium hards, low abrasive rocks to produce 2-3 end products.
