Solution Overview

Problem

The existing methods for separating inorganic materials from crushing balls are time-consuming due to the weak force of contact between the balls and the sieve, leading to prolonged separation times.

Innovation Solution

A method involving causing the crushing balls to collide against a mesh member to separate the inorganic material attached to them, which allows for a stronger force of contact and faster separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If inorganic material attached to crushing balls is sieved through a sieve to separate the inorganic material from the crushing balls, then the separation process can be performed, but the force with which the crushing balls are in contact with the sieve is relatively weak and thus a period of time taken to separate the inorganic material from the crushing balls increases

Engineering Contradiction:

Core Design Contradiction:

Loss of timeVSForce

Solution Approach 1:

Instead of passing the crushing balls through a stationary sieve (traditional approach), the patent inverts the approach by having the mesh member rotate and passively allow balls to collide with it during normal ball mill operation. The crushing balls themselves become the active element that drives separation through their own motion, rather than being passively pushed through a sieve.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The ball mill operation itself provides the separation function without requiring a separate sieving step. The crushing balls' natural motion and collision with the rotating mesh member during milling automatically separates the inorganic material, making the system self-sufficient for both crushing and separation functions.

Inventive Principle:

Principle #25Self-service

2Productivity

If traditional sieving method is used to separate inorganic material from crushing balls, then the separation can be performed, but the contact force between balls and sieve is weak leading to prolonged separation time

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSForce

Solution Approach 1:

The patent reverses the traditional sieving mechanism by having the mesh member rotate while the crushing balls remain in their normal milling positions. The balls collide with the mesh member during their natural motion, creating strong contact forces without requiring a separate sieving operation.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent combines the crushing function and separation function into a single integrated process. The ball mill simultaneously performs both material crushing and inorganic material separation through the rotating mesh member, eliminating the need for separate sieving equipment and operations.

Inventive Principle:

Principle #5Merging (Combining)
