Do You Know The Compression Ratio Of The Screw Jul 31, 2018

The compression ratio of the screw, also known as the geometric compression ratio of the screw, is the ratio of the first groove volume of the screw feed section to the last groove volume of the homogenization section. The compression ratio of the screw is determined by the ratio of the density of the product to the density of the material to be materialized. The compression ratio is an important indicator for determining whether the granular plastic is effective for plasticization and compaction and determining the internal pressure strength of the product.
