Basket Mill Bypass Flow Path for High-Viscosity Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional basket mills experience inadequate mixing of materials and prolonged processing times, especially when grinding high-viscosity materials, leading to quality issues.
Innovation Solution
The introduction of a bypass flow path with a second conveyor device, utilizing pump impellers to generate additional material flow parallel to the grinding chamber, enhances mixing and circulation within the grinding container, and the incorporation of flow installations and a cooling device to improve turbulence and cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If material flows only through the grinding chamber, then grinding function is achieved, but mixing efficiency is insufficient and processing time is prolonged
Solution Approach 1:
The flow path is segmented into two parallel paths: one through the grinding chamber and another through the bypass flow path. This segmentation allows material to be divided into multiple streams, with one stream undergoing grinding while another stream circulates to enhance mixing, thereby resolving the contradiction between grinding function and mixing efficiency
Solution Approach 2:
The bypass flow path acts as an intermediary mechanism that facilitates additional circulation and mixing of the material without interfering with the primary grinding function. This intermediary path enables enhanced mixing efficiency while maintaining the original grinding process
2Ease of operation
If conventional basket mill structure is used, then device complexity is low, but mixing of high-viscosity material is insufficient
Solution Approach 1:
The device structure is segmented by adding a bypass flow path with a second conveyor device, creating a dual-path system. This segmentation enables enhanced mixing capability for high-viscosity materials while maintaining relative structural simplicity through modular addition rather than complete redesign
3Productivity
If grinding speed is increased, then productivity improves, but heat input to material increases
Solution Approach 1:
The material flow is segmented into parallel paths, allowing continuous circulation and cooling through the bypass path while maintaining high-speed grinding in the grinding chamber. This segmentation enables heat dissipation through the circulating stream, permitting higher grinding speeds without excessive heat accumulation
Solution Approach 2:
The bypass flow path enables continuous circulation of material through the grinding pot, providing ongoing cooling and heat dissipation. This continuous action allows sustained high-speed grinding by constantly removing heat from the system, preventing temperature buildup that would limit grinding speed

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration significantly reduces processing time for high-viscosity materials, improves mixing efficiency, and increases grinding speed while maintaining effective cooling and preventing heat input.
Implementation Method 1
the first conveying device is formed by a first pump impeller. The conveyance of the material to be ground to generate the flow through the grinding chamber is thus effected by a rotary drive of the first pump impeller
Implementation Method 2
incorporation of flow installations and a cooling device to improve turbulence and cooling efficiency
