Block Type Connector
Category
round steel link chain connectors, round link mining chain connectors, DIN 22252 mining chain, DIN 22255 flat link chain, DIN 22258-3 block type connectors, mining conveyor chain, flight bar chain system
Application
Armored Face Conveyors (AFC), Beam Stage Loaders (BSL), coal plows
AID Block Type Connector is designed and made to DIN 22258-3, with high alloy steel to meet the full mechanical properties.
The Block Type Connector is used for connecting DIN 22252 round link chains and DIN 22255 flat link chain in vertical position only.
The assembly of Block Type Connector is as shown above illustrations.
As an important accessory of scraper and slag extractor in coal mine, the connector has large cyclic bearing capacity and high utilization rate; In the process of operation, it bears tensile force, friction with chain, coal block and sprocket, and is eroded by mineral water.
The AID mining chain link connectors with reasonable geometric size, through rough machining, semi finishing, finishing, heat treatment, pre stretching, shot blasting and other processes, has high strength, high toughness, wear resistance, corrosion resistance, good cold bending ability, high breaking force and other comprehensive mechanical properties.
