The Mobile Crushing and Screening Plants
(1) Applicantion
　The mobile crushing and screening plants is applied to multistage crush large materials, and then screen the discharges according to their different specifications. The whole set plants is widely used in mine, building material, highway, rail way and hydropower industries, etc., finish crushing and screening operations at one time, produce required size and output for consumers.

(2) Composition and working principle
　The mobile crushing and screening plants is composed of primary crushing and screening station and secondary one, belt conveyor, etc. Every crushing station is an independent working unit, they can respectively assume their different responsibility, and the belt conveyer is responsible for material transmitting and piling up between each crushing station.
2.1 The primary crushing station includes the following machines:
　The GZDO724 Feeder
　The PE400 Jaw Crusher
　The Half Suspension Trailer Chassis
　The Other Supporting Parts
2.2 The secondary crushing and screening station includes the following machines:
　The PF1210 Impact Crusher
　The 3YK1545 Vibrating Screen
　The WCD-610 Sand Washing Machine
　The Electric Equipment Controlling System
　The Washing Device
　The Half Suspension Trailer Chassis
　The other supporting parts
2.3 The Belt Conveyor
　It is responsible for transmitting materials to each crushing station and stacking.

(3) Features and Benefits
　The plants has the advantage of reasonable matching, unobstructed discharge all line, reliable working, convenient operation, high efficiency and saving energy. Especially the mobility is very good, so it can extend with the raw material places or the construction place, and it can also make multiple matching, get to different product requirements.
