In overseas mining operations, screening equipment plays a critical role in ore classification and production line stability. The installation quality, structural design, and service life of wear components such as screen panels and blind plates directly impact operational efficiency, equipment reliability, and maintenance costs.
A large open-pit mining company in the Democratic Republic of Congo (DRC), specializing in non-ferrous metal ore mining, crushing, and screening, encountered persistent operational failures after commissioning its production line. Two major problems became severe bottlenecks affecting stable production:
These recurring failures significantly disrupted continuous production, increased downtime, and raised spare part replacement costs, becoming a major operational challenge for the mine.

The mining project operates under demanding conditions, including high throughput, hard ore materials, and continuous heavy-duty screening processes. Due to prolonged high-load operation, equipment issues became increasingly severe.
Because of limitations in the original installation structure, unsuitable fastening methods, and poor compatibility between vibration parameters and screen panel fixing systems, the vibrating screen experienced repeated panel movement under high-frequency vibration.
During operation, screen panels became loose, shifted position, and even detached completely. This resulted in:
Routine maintenance, fastening, and replacement efforts failed to eliminate the problem at its root cause.

At the feed inlet, ore materials continuously impacted the blind plate at high velocity. Due to an unreasonable feed distribution structure and concentrated material impact, localized wear developed rapidly.
The original system suffered from:
Frequent blind plate replacement increased overseas operational expenses and placed additional burdens on maintenance teams.
After repeated unsuccessful repair attempts, the client sought a long-term technical solution and contacted Red Star Screens for professional engineering support.
Upon receiving the request, Red Star Screens immediately launched a dedicated overseas mining support process and assembled a professional technical service team.
Through close communication with on-site personnel and detailed analysis of operating conditions, the team systematically evaluated:
After comprehensive evaluation, the technical team identified the root causes:
The original fixing system used standard clamps and simple compression methods that lacked sufficient strength and vibration resistance.
Under continuous high-frequency vibration, locking components loosened, causing panel instability and detachment.
Insufficient contact between screen panels and support beams created vibration gaps and resonance movement, significantly increasing the risk of loosening and displacement.
Ore materials concentrated their impact on a single area of the blind plate, without proper buffering or material dispersion, leading to localized overload and premature wear.
Rather than simply replacing worn components, Red Star Screens adopted a root-cause engineering approach and developed a customized integrated solution combining:
Based on actual operating conditions at the DRC mine site, Red Star Screens implemented a fully customized technical rectification program, providing engineering guidance, technical support, installation assistance, and commissioning services throughout the project.
The original installation system was redesigned completely.
The team optimized:
Installation spacing, compression force, and assembly procedures were standardized to eliminate vibration gaps and resonance risks.
High-strength, vibration-resistant screen panels suitable for hard ore applications were also selected to improve durability and operational reliability.
As a result, panel jumping, loosening, and detachment were eliminated at the structural level.
To address abnormal blind plate wear, the feed system was redesigned.
The optimization included:
The upgraded system enabled smoother and more even ore feeding, reducing concentrated impact forces on the blind plate.
At the same time, high wear-resistant feed blind plates and improved installation geometry further extended service life.
Throughout implementation, the Red Star Screens technical team provided continuous remote engineering guidance to ensure accurate installation, efficient commissioning, and minimal production interruption.
Following technical optimization and commissioning, the mine successfully eliminated its long-standing screening equipment failures.
The upgraded mounting system achieved stable and reliable operation under continuous heavy-duty conditions.
No loosening, jumping, or detachment occurred during operation, significantly improving equipment reliability and production continuity.
Unexpected downtime caused by screen failures was eliminated.
Following feed system optimization, ore materials entered more evenly and smoothly.
Abnormal localized wear was effectively resolved, and blind plate service life increased significantly, greatly reducing replacement frequency and spare parts costs.
With dramatically reduced equipment failure rates, screening efficiency and separation accuracy became stable and reliable.
Maintenance workload, emergency repairs, and spare part consumption were substantially reduced, enabling the mine to improve productivity while lowering operational costs.
This successful DRC mining rectification project once again demonstrates the overseas technical service capability and engineering expertise of Red Star Screens.
Facing complex mining environments and demanding working conditions, Red Star Screens remains committed to solving customer problems at the source—not simply replacing parts.
