It is the major equipment for bulk transport by scraper chain in a closed shell
It Has small volume, strong sealing, good rigidity, flexible, easy installation and maintenance , It can enhance Workers operating conditions and reduce Environmental Pollution.The Principle of scraper conveyor adopts internal friction and side pressure to ensure steady state between material layer. It can do  continuous stream by conveying chain.conveyor adopts internal friction and side pressure to ensure steady state between material layer. It can do  continuous stream by  conveying chain

usage and classify  

scraper transporter is widely used for Metallurgy, building materials, electric power, chemical, cement, coal, mining, port, wharf, grain and oil, food, feed, and other industries and departments. It is suitable for powder, granular and small lump materials
classify   
1、MS type   horizontal chain conveyor
2、MC type  Vertical scraper conveyor
3、 MZ type  Z type  scraper conveyor

 horizontal chain conveyor can be devided into Normal type and large tilt type. The installation angle of Normal type is 0°≤α≤15°, large tilt type is 15°＜α＜30°
the requirement of materials
1、   
unit weight : r=0.2～1.8t/m3 
2、
Temperature : the temperature of materials  t＜100℃ 
3、 
Water content : it is based on the material and viscosity.
4、
Granularity: it is based on the hardness,it is not easy to transport  great granularity materials.
