Crushing Mill Compactor Apparatus for Refuse Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crushing mills face inefficiencies in processing incoherent scrap masses, leading to inefficient and discontinuous crushing processes, and safety issues due to spillage from the crushing chamber back to the feed box.
Innovation Solution
A crushing mill equipped with a compactor apparatus and a thruster member that compact and transfer refuse from an inlet pipe to a crushing chamber, synchronized with the loading process, and an introduction element that ensures the crushing chamber remains closed to prevent spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thrust means are used to push refuse into the crushing chamber, then the refuse can be fed into the chamber, but the thrust means are inefficient when dealing with incoherent scrap masses of any shape, size and volume
Solution Approach 1:
The compactor apparatus performs preliminary compacting of the refuse mass in the inlet pipe before it is thrust into the crushing chamber. This preliminary action transforms the incoherent scrap mass into a compacted form, making subsequent handling by the thrust means much more efficient and enabling continuous operation.
2Ease of operation
If the crushing chamber is open to receive refuse, then loading is possible, but refuse can spill from the crushing chamber and return toward the feed box creating safety problems
Solution Approach 1:
The introduction element acts as an intermediary between the inlet pipe and the crushing chamber. It provides a controlled interface that allows compacted refuse to be transferred into the chamber while preventing uncontrolled spillage. The element synchronizes its movement with the compacting and thrusting operations, opening to allow loading and closing to prevent spillage.
3Productivity
If a compactor apparatus is added to compact refuse in the inlet pipe, then continuous and efficient crushing is achieved, but the device complexity increases
Solution Approach 1:
The compactor apparatus is integrated into the existing inlet pipe structure of the crushing mill. The presser elements are positioned within the inlet pipe, and the compacting operation merges with the existing loading and thrusting sequence. This merging approach adds compacting functionality while utilizing existing structural elements, thereby limiting the increase in overall system complexity.
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
Enables rapid, uniform, and continuous crushing of scrap regardless of shape, size, or volume, while maintaining safety by preventing spillage and minimizing downtimes.
Implementation Method 1
one or more presser elements positioned in correspondence to the inlet pipe of the refuse to be crushed and configured to be moved from at least a first inactive position, in which they allow the loading of the refuse to be crushed into the inlet pipe, to at least a second active position in which they compact the refuse in the inlet pipe
Implementation Method 2
the mass of compacted refuse in the inlet pipe is sent to the crushing chamber by means of the thruster member
