Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cone crushers have low crushing efficiency due to variable gap sizes, non-uniform material size output, large spatial requirements, and logistical complexities, with manual labor limiting throughput and increasing injury risks, and parts are difficult to insert or remove.
Innovation Solution
An articulable-arm-mountable pulverisation apparatus with a modular design featuring a unitary drive unit that can be easily replaced, a rotatable element with uniform gap width, and a scoop for automated material loading, allowing for interchangeable parts and efficient attachment to excavating machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cone crusher with gyratory rotation is used, then material can be crushed, but crushing efficiency is low due to variable gap sizes
Solution Approach 1:
The crusher housing is divided into multiple segments that can be independently adjusted, allowing each segment to be positioned to create a uniform gap width around the rotating element. This segmentation enables precise control of the crushing gap to ensure uniform material size output while maintaining high crushing efficiency.
2Productivity
If large-scale dedicated cone crushers are used, then material can be broken down, but spatial requirements increase and logistical complexity increases
Solution Approach 1:
The crusher is designed with interchangeable components including multiple rotatable elements with different geometries and multiple housing segments that can be reconfigured. This universality allows a single crusher unit to perform multiple crushing functions and adapt to different material processing requirements, reducing the need for multiple dedicated machines and thereby reducing spatial requirements and logistical complexity.
3Productivity
If manual loading is used, then material can be loaded into the cone crusher, but throughput is limited by labor force and injury risk increases
Solution Approach 1:
The crusher incorporates an automated material loading system with a hopper and conveyor mechanism that automatically feeds material into the crushing chamber. This self-service loading system eliminates the need for manual material handling, thereby increasing throughput by removing labor force limitations and eliminating injury risks associated with manual loading operations.
4Productivity
If traditional cone crushers are used, then material can be crushed, but individual parts are difficult to insert or remove
Solution Approach 1:
The crusher is constructed with modular segments including the housing, drive unit, and rotatable elements that are designed to be easily detached and reattached. Each segment is equipped with standardized connection interfaces that allow for quick replacement without requiring complex disassembly procedures, thereby facilitating easy maintenance and repair operations while maintaining crushing productivity.
