Vibration Mill Sliding Guide for Planar Oscillation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibratory mills experience undesirable vertical oscillations and tilting movements due to their suspension or setup, which affect the grinding process by introducing unwanted movement components perpendicular to the oscillation plane.
Innovation Solution
A vibratory mill design featuring a rigid holding device with a sliding guide that restricts movements to be parallel to the oscillation plane, using a frame-like structure with guide elements to prevent rotation or tilting, and an eccentric drive to ensure vibrations occur only in a controlled plane, along with a cooling system and adjustable discharge mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the grinding unit is suspended or set up on a fixed surface, then the desired vibration of the grinding vessel in an oscillating plane is achieved, but vertical vibrations and tilting movements occur perpendicular to the oscillation plane
Solution Approach 1:
A sliding guide is introduced as an intermediary component between the grinding unit and the fixed surface. This sliding guide allows the grinding unit to oscillate in the desired plane while preventing unwanted vertical vibrations and tilting movements, thus mediating between the oscillation drive and the fixed support structure.
Solution Approach 2:
The sliding guide changes the movement parameters by allowing motion only in the oscillation plane while constraining motion in perpendicular directions. This parameter change restricts the grinding unit to planar oscillations and eliminates vertical and tilting components.
2Ease of operation
If vertical movement play is provided for the grinding elements, then oscillating movement is enabled, but vertical oscillations and tilting movements are generated
Solution Approach 1:
The movement freedom is segmented into allowed and forbidden directions. The sliding guide segments the six-degree-of-freedom space into permitted oscillation in the horizontal plane and forbidden vertical and tilting movements, allowing oscillation capability while preventing precision-degrading motions.
3Adaptability or versatility
If the grinding unit is allowed to rotate or tilt, then oscillating movement in multiple directions is achieved, but grinding uniformity is compromised
Solution Approach 1:
The sliding guide acts as a mediator that selectively transmits desired oscillating movements while blocking unwanted rotation and tilting. This intermediary component maintains adaptability for planar oscillation while ensuring grinding uniformity by preventing multi-directional movements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures that the grinding unit performs only displacement and rotary movements within the oscillation plane, minimizing perpendicular movements and enhancing the uniformity and efficiency of the grinding process by maintaining a stable grinding gap and preventing temperature rise through cooling.
Implementation Method 1
the sliding guide includes at least one guide element which protrudes laterally beyond the basic contour of the housing of the grinding unit and is firmly connected to the grinding unit, and at least one guide counter-element which is firmly connected to the holding device
Implementation Method 2
the grinding unit can comprise a cooling device acting on the grinding wall, which preferably has at least one cooling channel directly adjoining the grinding wall on the outside

AI summary
The invention relates to a vibration mill, particularly a disk vibration mill (1), comprising a grinding unit (4) and an oscillating drive (3) by which the grinding unit (4) can be excited to oscillate. As an advantageous development, particularly vertical oscillations and tilting movements of the grinding unit and the associated disadvantages can be largely avoided by providing a holding device (2) to which the oscillating drive (3) is fastened and on which the grinding unit (4) is displaceably mounted plane-parallel to a vibration plane (S) by means of at least one sliding guide (12) engaging the grinding unit (4).
