The core features of vertical impact crushing
High-efficiency crushing: Large crushing ratio and high output, ideal for large-scale production needs. Controllable particle size: By adjusting the impeller speed, modifying the structure of the crushing chamber, or altering the feeding method, the particle size of the finished product can be precisely controlled (typically adjustable between 3-8 mm).

Functions and Roles of Conveyor Supports
Support and Load Bearing: The conveyor frame primarily supports the conveyor belt and idlers, ensuring stable operation of the conveyor. Fixing and Adjustment: The idler bracket can secure the idlers and adjust their angles to meet various conveying requirements.

Conveyor Support Types and Structural Features
Roller supports are categorized into groove-type supports and self-aligning supports. The groove-type support features a two-section roller design with a hollow structure, combining the functions of reducing belt tension and providing self-cleaning capabilities. The self-aligning support enhances stability by being mounted on both sides and boasts dustproof, waterproof, and impact-resistant properties.

Key Considerations for Selecting Conveyor Drum Rollers
Load Capacity: Select the roller material and model based on the weight of the conveyed material to ensure adequate load-bearing capacity. Roller Length: Typically, use the rule “Conveyed Material Width + 50mm” to ensure stable conveyance of the material. Surface Treatment: Choose materials and processes according to the conveying environment—for example, in humid environments, rust-proof treatment is required; in the food industry, mirror-like polishing is necessary.
