MS horizontal conveyor, because that means, scraper conveyor chains are buried in the material, so called MS scraper conveyor, And because the wind was buried trigger 500mm therefore called slot width MS50 type scraper conveyor. Materials to be conveyed with force and the lateral pressure inside brush etc. Vertical conveyor, which mainly rely on materials of arch characteristics. Sealing material in the slot machine by scraper chain in the direction of movement, and is constantly under the thrust of the feeding and prevent slipping on the resistance, transverse resistance, transverse lateral pressure, thus increasing the friction material, when materials within the friction between the inside wall of the room than material and the friction and weight materials, materials with scraper chain in movement, some materials are of vibration, thus will sometimes arch in the process of conveying material to produce a lag phenomenon chain, transmission capacity. Scraper conveyor consists mainly of closed cross-section of the shell (machine), scraper chain, driving device and a device etc. Parts. The equipment is simple in structure, smal
