Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional crushing apparatuses face issues with material property deterioration due to increased heat generation and inefficient particle size distribution, especially when crushing high-fat or high-sugar materials, leading to oxidation and coalescence, which affects the quality and recovery rate of the final product.
Innovation Solution
A crushing apparatus design featuring rotating disks with through holes to gently introduce materials and guide powders to the center for minimal rotational force application, combined with adjustable blades and guide disks to control airflow and particle flow, allowing for efficient crushing and sorting without excessive force or heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed rotation of the rotating disk is used to intensify crushing force, then crushing efficiency is improved, but heat generation increases causing material property deterioration
Solution Approach 1:
The rotating disk is segmented into multiple blades arranged radially, allowing the crushing action to be distributed across multiple contact points rather than a single high-force impact, reducing localized heat generation while maintaining overall crushing efficiency
Solution Approach 2:
The blade configuration and rotational speed are optimized to create different crushing intensities in different regions of the crushing section, allowing gentle crushing in areas prone to heat generation while maintaining efficient crushing in other areas
2Manufacturing precision
If the classifying gap is narrowly set to improve particle size distribution, then crushing precision is improved, but material may stay inside the crushing section without being discharged
Solution Approach 1:
The rotating disk with blades creates dynamic airflow patterns that continuously move crushed material through the narrowing classifying gap, preventing material from stagnating even when the gap is set narrowly for precise particle size control
Solution Approach 2:
The rotation of the disk generates pneumatic flow that carries crushed material through the classifying section, enabling efficient discharge even with narrow classifying gaps by using air flow rather than purely mechanical conveyance
3Productivity
If high-fat or high-sugar materials are abruptly impacted against the rotating disk, then crushing efficiency is improved, but fat or sugar scatters causing powder coalescence and adhesion
Solution Approach 1:
The blade configuration applies crushing force in multiple incremental stages rather than a single excessive impact, preventing the scattering of fat and sugar while achieving sufficient crushing of high-fat or high-sugar materials
Solution Approach 2:
The blade design and rotational characteristics act as an intermediary that mediates between the material and the crushing force, distributing the impact in a way that prevents direct abrupt collision that would cause fat or sugar scattering
