Servicing of Roller Press Weld Repair and Profiling in Cement Plants by Tarek Nasser Al Akeel Co. in Saudi Arabia
Introduction
In the cement industry, roller presses grind raw materials such as clinker and slag. As these machines operate under high pressure and handle abrasive material, they are subject to severe wear. Tarek Nasser Al Akeel Co. (TNA) specializes in the reconditioning of roller presses, focusing on weld repair and profiling to enhance life and efficiency.
Importance of Roller Press Maintenance
Roller presses are designed to crush materials through high-pressure compaction, leading to abrasion and localised impact wear on the rollers. Over time, this wear can result in decreased grinding efficiency and increased energy consumption. Weld repairs and profiling, are essential to maintain the roller presses work efficiently.
Weld Repair Techniques
Hardfacing
One of the primary methods employed by TNA for roller press maintenance is hardfacing. This process involves applying a wear-resistant material to the surface of the rollers to restore their dimensions and enhance their wear characteristics. TNA utilizes advanced welding techniques such as:
Flux-Cored Arc Welding (FCAW): Effective for thicker materials and provides excellent penetration and fusion.
This and other welding techniques are selected based on the specific wear patterns observed on the roller surfaces and the operational conditions of the cement plant.
Profiling
After the hardfacing process, profiling is conducted to restore the original geometry of the roller surfaces. This involves grinding the welded surfaces to achieve the required dimensions and surface finish. TNA employs insitu equipment to ensure that the rollers are accurately profiled, which is critical for maintaining the grinding efficiency.
TNA -Can rebuild both type KHD -Straight line profile and Chevron pattern for other Roller presses such as Polysius ,Thyssen Krupp with suitable on site rebuilding automated profile making machine using suitable welding wires with hardness range 50-55 RC
Process Overview
The servicing process at TNA is structured to ensure thorough and efficient maintenance of roller presses:
Initial Inspection: An assessment of the roller press is conducted to identify the amount of wear, wear patterns, cracks, and other damage.
Weld Repair: Based on the inspection results, appropriate building up and hard facing techniques are applied to restore the worn areas of the rollers.
3. Profiling: After hardfacing, the rollers are given suitable profile by weld bead either chevron or straight .
4. Quality Control: Each repaired roller undergoes rigorous quality checks such as pre and Post cleaning ,Stress relieving ,Short blasting to get the clean surface before welding post weld DP test, to ensure crack free welding before handing over repaired roller to client.
5. Reinstallation: The serviced rollers are then reinstalled in the roller press, ensuring proper alignment with the existing system. TNA Contracting division also undertake removal and installation of Roller presses -Several cement plant in KSA have benefited from efficient services of TNA Contracting Division as cement plant specialist.
