Mobile Crushing Station Modular Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crushing stations in mining operations face inefficiencies due to increased transportation distances as the mine face advances, requiring costly relocation and significant downtime for disassembly and reassembly, which increases operational costs and reduces efficiency.
Innovation Solution
A self-propelled, mobile crushing station with an integral rock crusher and discharge conveyor that can receive and comminute excavated material from multiple dump trucks simultaneously, eliminating the need for disassembly and reducing the requirement for massive retaining walls and earthen ramps, allowing for efficient repositioning without substantial downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the crushing station is relocated closer to the mine face, then transportation distance is reduced and efficiency is improved, but the crushing station must be shut down, disassembled, and reassembled which causes significant downtime and increased costs
Solution Approach 1:
The crushing station is divided into multiple modular components including a tower structure with feed orifice, crushing mechanism, discharge orifice, and conveyor system. These segmented modules can be independently assembled and disassembled, enabling rapid relocation without complete shutdown of the mining operation. The modular design allows for efficient reconfiguration at new positions closer to the mine face.
Solution Approach 2:
The crushing station is designed with mobile capabilities including crawler tracks or wheeled assemblies that enable the entire structure to be moved as a integrated unit or in modular sections. This dynamic design eliminates the need for complete disassembly and reassembly, allowing the crushing station to be repositioned quickly to maintain optimal distance from the advancing mine face.
2Stability of the object's composition
If traditional crushing stations are used with massive retaining walls and earthen ramps, then structural stability is ensured, but the infrastructure requires enormous construction effort and cannot be easily repositioned
Solution Approach 1:
The traditional massive retaining wall and earthen ramp infrastructure is replaced with modular support structures including steel framework components and adjustable bracing systems. These segmented support elements provide necessary structural stability while being easily assembled and disassembled for relocation, eliminating the need for permanent infrastructure construction.
Solution Approach 2:
The static mechanical support system of massive earth structures is replaced with a mobile mechanical framework system using steel beams, columns, and adjustable support mechanisms. This substituted system provides equivalent structural stability while incorporating mobile elements such as crawler tracks and hydraulic positioning systems that enable easy repositioning as the mine face advances.
3Productivity
If the crushing station is moved frequently to keep up with the advancing mine face, then transportation efficiency is maintained, but the cost and complexity of relocation operations increase
Solution Approach 1:
The crushing station design integrates the tower structure, crushing mechanism, discharge system, and mobile platform into a unified modular assembly. This merged design allows the entire crushing operation to be relocated as a single integrated unit or in coordinated modular sections, significantly reducing the complexity of relocation operations compared to moving separate components.
Solution Approach 2:
The crushing station incorporates self-contained features including integrated conveyor systems that can be quickly deployed, self-supported tower structures that require minimal external assembly, and mobile platforms with built-in positioning capabilities. These self-service characteristics reduce the complexity and resources required for relocation operations.

AI summary
A mobile crushing station for receiving and comminuting excavated material from earth moving vehicles provides at least one moveable skip connected to a chassis or frame for receiving material from vehicles, such as rear unloading vehicles like dump trucks. The skips are configured to move to dump material fed into the skips into a feed hopper. The feed hopper is positioned to guide material onto a feed conveyor, such as an inclined apron conveyor. The feed conveyor is configured to transport material to a feed orifice of a crushing device, such as a sizer, a crusher, or a crushing circuit. The crushing device is configured to crush material fed into the crushing device. The crushing device also has a discharge orifice that is positioned above a portion of a discharge conveyor. The mobile crushing station is moveable so it may be repositioned closer to an excavation site as excavation activities progress.
