Portable Screening Plant Telescopic Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable washing and screening plants for stone and sand products require external cranes for configuration changes and are not legally transportable in their full capacity due to size and weight constraints.
Innovation Solution
A portable assembly comprising a scrubbing mill, vibratory screen, and fine material washer mounted on a trailer, utilizing telescoping tube supports and actuators to transition between transport and operational configurations without external crane assistance, allowing for legal highway transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the assembly is designed with significant capacity to process stone and sand products, then the processing capacity is improved, but the assembly becomes too massive to be legally transportable on state-regulated highways
Solution Approach 1:
The assembly is divided into separable components including the scrubbing mill, vibratory screen assembly, and fine material washer that can be independently positioned and configured. This segmentation allows the components to be arranged in a compact transport configuration while maintaining full processing capacity in operational configuration.
Solution Approach 2:
The assembly incorporates movable and adjustable components with telescoping tube supports and positioning mechanisms that enable dynamic reconfiguration between transport and operational states. The scrubbing mill and screen assembly can be moved between positions without removal, allowing the same structure to serve dual purposes.
2Productivity
If the assembly is designed with significant capacity, then the processing capacity is improved, but the assembly requires external crane assistance for configuration changes
Solution Approach 1:
The assembly incorporates self-contained positioning mechanisms including telescoping tube supports, actuators, and locking mechanisms that enable the components to be reconfigured without external crane assistance. The system serves itself by having integrated mechanisms for raising, lowering, and securing the scrubbing mill and screen assembly.
3Productivity
If the assembly includes all operating components in a compact design, then the processing capacity is improved, but the components must be removed for highway transport
Solution Approach 1:
The trailer frame and support structures are designed to serve dual functions: providing stable support during operational configuration and enabling compact transport configuration. The telescoping tube supports and positioning mechanisms serve both operational and transport purposes, eliminating the need for component removal.

AI summary
A portable screening and washing assembly includes a frame, and in addition, a scrubbing mill, a vibratory screen assembly and a fine material washer, all of which are mounted on the frame. Both the scrubbing mill and the fine material washer are adapted to move between a transport configuration and an operational configuration.
