Causes of tailing in extrusion granulation and countermeasures
Thread Content
In production using extruders and pelletizers, particle tailing often occurs. This post will discuss the reasons for tailing and the measures to address it. Please explain the product production and trailing situation
For example, in the production of polyoxymethylene, when granulation is carried out using a granulator, tailing occurs: 1. There is a distance between the cutting blade and the die, preventing them from being in close contact, which results in tailing； The issue can be resolved by increasing the push pressure of the cutting blade. 2. The cutting blade is damaged, which causes trailing ； Sharpen the blade or replace it with a new one. 3. The water temperature is too high, preventing the particles from contracting effectively, which results in trailing ； The water temperature can be appropriately reduced
Poor cooling makes it difficult to cut, resulting in trailing strands and particles that do not separate
