Counter-Driven Screw Crusher for Centralized Material Flow

The cutting and crushing blades are segmented into modular blocks that can be independently arranged on the shafts. These segmented blocks allow for the integration of additional functional elements like feeders while maintaining the basic crushing capability. The segmentation enables flexible configuration to achieve both simple structure and improved productivity.

The cutting and crushing blades are designed with multi-functionality, serving both as cutting edges and as part of the material directing system. The blades are configured to simultaneously perform separation and guide material toward the center, eliminating the need for separate complex feeding mechanisms while improving productivity.

The cutting blocks on the counter-rotating shafts are positioned asymmetrically with intentional gaps rather than complete overlap. This asymmetric arrangement creates controlled material flow paths that prevent edge jamming while maintaining effective crushing in the center. The gaps allow material to be gradually fed into the crushing zone rather than being abruptly compressed.

The cutting blocks serve as intermediaries between the counter-rotating shafts and the material being processed. They are positioned to first guide material toward the center and then apply crushing force, mediating the interaction between the shafts and material to prevent direct contact at the edges that would cause jamming.

The scraping blocks are designed with multi-functionality, serving both as cleaning elements for the gaps between blades and as additional crushing elements. The blocks are positioned and shaped to scrape adhered material from the blade gaps while simultaneously applying crushing force to the material in those regions, eliminating the need for separate cleaning mechanisms.

The cleaning function and crushing function are merged into a single integrated system. The scraping blocks perform both cleaning and crushing operations simultaneously, combining what would traditionally be separate functions into one unified component, thereby improving ease of manufacture without significantly increasing device complexity.

The cutting blocks are arranged to engage material in a periodic sequence as the shafts rotate, with each block engaging at different positions. This periodic engagement allows material to be progressively separated in both machine directions while maintaining reduced specific pressure. The periodic action creates multiple separation opportunities as material passes through different blade configurations during rotation.

The blade arrangement incorporates dynamic elements where the engagement of cutting blocks changes continuously during rotation. The helical arrangement combined with counter-rotation creates a dynamic separation pattern that adapts to material flow, enabling effective separation in both directions while maintaining optimal pressure distribution throughout the crushing process.
