How To Pairing, Installation And Maintenance DAWSON The Mining Flat Link Chains

Views: 25    

We're glad to share the ways of Pairing, Installation and Maintenance the Mining Flat Link Chains.

1. Product Features

Mining high-strength flat link chain has the characteristics of large bearing capacity, strong wear resistance, good impact toughness and long fatigue life.

2. Main Purpose and Scope of Application

It is widely used in Armored Face Conveyor (AFC) and Beam Stage Loader (BSL) in coal mine.

3. Executive Standard

MT / t929-2004, DIN 22255

4. Pairing and Installation

4.1   Flat link chains pairing

The accurate pairing of mining flat link chains is essential for the successful operation of the conveyor. When the chain leaves the factory, it is paired with one-to-one chain links to ensure that the scraper is in a straight line and the stability of the scraper in the middle groove. Place the paired flat link chains in a packing box and attach a label to each paired chain. Paired chains shall not be used separately. Pairing tolerance refers to the maximum allowable length of any pairing chain.

4.2   Flat link chains installation

The paired flat link chains are correctly assembled on the scraper to optimize the performance of the chain. This will ensure that the tolerances on both sides of the chain are minimized and that the chain tension is effectively controlled when the scraper conveyor is initially started. Ensure a good straight face and minimize the difference of pretension.

The chain is installed in pairs, and the long paired chain and short paired chain are assembled in turn. New sprockets and baffles are usually assembled when installing new flat link chains.

Make sure that the flat link chains do not run when it is first installed without lubrication guarantee. If it runs without lubrication, the chain link will wear quickly.

Ensure that the correct tensioning process is suitable for scraper conveyors and transfer machines. Check the pre tension every day in order to create a suitable tension value for each chain. Because the chain itself and its cooperation with the conveyor need to be run in place, the first few weeks of equipment operation are very critical.
