Application and Role of Spiral Blades in Crushers

Spiral blades play a crucial role in crushers (especially models like dual-shaft shredders and single-shaft shredders that handle complex or difficult materials). Their core applications and functions can be summarized as follows:

Forced Feeding and Stable Conveying: This is the most basic and primary function of spiral blades. They are typically installed below the crushers inlet or connected to the main shaft.

Material Pre-compression and Compaction: During the process of forcibly pushing materials, the structure of the spiral blades (especially the design of the pitch and the gap between the blade diameter and the inner cavity) creates a certain degree of compression and compaction on the materials.

Assisting in Overcoming Material Blockage: For materials that are prone to tangling and wrapping (such as waste wires, textiles, films, and plastic bags), relying solely on gravity feeding can easily cause knots and accumulation at the inlet or cutter rollers, leading to blockages.

Spiral blades in crushers are far more than just simple conveying components. They are a core device for ensuring efficient, stable, and reliable equipment operation, especially when processing difficult-to-feed materials. Their ability to actively force feed and stabilize material flow solves the pain points of traditional crushers that are prone to clogging, have low efficiency, and are difficult to handle specific materials. At the same time, they also help improve crushing efficiency, protect critical components, and enhance the equipments ability to handle complex materials. Selecting a crusher with suitable spiral blades is crucial for continuous and efficient operations in fields such as solid waste treatment and resource recovery.
