Highways , railways, construction stones factory production is along the long-distance , long construction period, if the traffic inconvenience to the subsequent increase in the construction of many unnecessary trouble, stone production and transport is a big difficulty, both human and material cost , but also affect the progress of the project . For this situation, the development of Zhengzhou KEFID launched mobile stone crushing equipment - mobile crushing station, highway , stone integrated production , railway construction to create a flow type of stone crushing production line.

The so-called mobile crusher is relative to the now commonly used in the production of mining crusher in terms of fixed and stationary crusher compared to the series crusher in addition to the use of flexible , mobile convenience , the series also comes crushing station there are sets of crushing and screening system , operating more smoothly. Primary crusher can choose according to production requirements jaw crusher ( coarse crushing ) , cone crusher, VSI crusher or impact crusher ( crushing plastic ) to produce a variety of different size aggregates , sand material with high flexibility to meet the different needs of the construction period .

Set of mobile station equipment production flow process and general fixed sets of sand and gravel production line process is similar, but the performance quality of architecture and integrated production model, the mobile station production line is more prominent. Piles of stone construction materials by a bulldozer / bin pushed to mobile crushing station feeder , the feeder above a strainer , large stones are isolated on top into the mobile crushing station. After classification of construction waste was sent by tracked mobile screening machine, a magnet fixed to the top of the track , all the garbage in the wire, screws, etc. to be cleaned out . After entering the mobile screening machine , sand tracked by the following one sent, were sent to a layer of gravel above the track , then rinse that can replace natural building materials such as fine gravel aggregate .
