Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing granulating and agglomerating tools require excessively long stirring times and yield low percentages of granulated materials in the 0.1-0.8 mm size range, limiting their effectiveness for producing finer granules.
Innovation Solution
A granulating tool with a disk-shaped element and V-shaped grooves on its circumferential surface, where the grooves are designed with specific dimensions and made of harder materials to enhance granulating efficiency, and optionally featuring swirl elements and multiple disk-shaped elements for improved performance.

Engineering Contradiction Analysis
1Productivity
If traditional stirring tools with radial arms are used for granulating, then the tool structure is simple, but the stirring time required is extremely long and the yield of fine granulated materials (0.1-0.8 mm) is low at 30-60%
Solution Approach 1:
The disk-shaped element is segmented into multiple V-shaped grooves that run parallel to the shaft axis. Each groove acts as an independent channel for material flow and granulation, increasing the effective working surface area and improving granulating efficiency without significantly increasing overall structural complexity
Solution Approach 2:
The invention transitions from traditional radial arm stirring (horizontal dimension) to axial groove structures (vertical dimension parallel to shaft). Material flows radially outward along the grooves from the shaft toward the periphery, utilizing the axial dimension of the grooves to enhance mixing and granulating action
2Productivity
If groove depth is increased to enhance granulating effect, then granulation efficiency improves, but material movement in radial direction is restricted
Solution Approach 1:
The groove depth is optimized to a specific parameter range (0.05-0.4 times the disk diameter, preferably 0.1-0.3 times) to balance two competing requirements: sufficient depth for effective granulation while maintaining adequate radial material flow. This quantitative parameter optimization resolves the contradiction between granulation efficiency and material movement
3Reliability
If groove walls are made of harder material to reduce wear, then tool durability increases, but manufacturing complexity and cost increase
Solution Approach 1:
Only the groove walls, which are the critical wear zones during granulating operation, are made of harder material. The rest of the disk-shaped element can be made of standard material. This localized application of hard material minimizes manufacturing complexity while maximizing durability where it is most needed
