Recently, the British premium bearing brand ROOS-LAIS successfully completed a bulk supply of bearings to the Shaping Coal Preparation Plant of Shanxi Jinshen Energy Co., Ltd. The company has tailored specialised bearing products for the plant’s vibrating screens, centrifuges, belt conveyors, crushers and other core coal washing equipment. With robust performance characteristics including dust resistance, impact resistance, strong sealing and a long service life, these specialised bearings help the plant enhance equipment operational stability and reduce operational and maintenance costs, providing a powerful boost to the efficient and safe production of coal washing and beneficiation.

The Shaping Coal Preparation Plant of Shanxi Jinshen Energy Co., Ltd. is situated in Hequ County, Xinzhou City, Shanxi Province. As a core coal preparation facility under Jinshen Energy, it has a designed annual processing capacity of 5 million tonnes and employs internationally advanced full-heavy-medium coal preparation technology. It serves as a major coal preparation and processing base in North China and has been awarded numerous honours, including ‘High-Quality and High-Efficiency Coal Preparation Plant’ and ‘Quality Standardisation Coal Preparation Plant’. Coal washing operations are characterised by harsh conditions, with a combination of high dust levels, intense vibration, heavy impact loads and slurry corrosion placing extremely high demands on the sealing performance, load-bearing capacity and wear resistance of bearings. The reliability of the bearings in core equipment directly determines the operational efficiency and safety standards of the entire production line.

As a precision bearing manufacturer originating in the UK, ROOS-LAIS has specialised in the industrial bearing sector for many years. The company possesses automated precision production equipment and robust technical R&D capabilities. Its products incorporate internationally recognised manufacturing processes and reinforced structures, offering specialised engineering expertise in the fields of friction management, metallurgy and power transmission. ROOS-LAIS is particularly adept at providing customised bearing solutions for demanding operating conditions, such as those found in mining and coal processing. The bearings supplied on this occasion are precisely tailored to meet the diverse operational requirements of the various pieces of equipment at the Shaping Coal Preparation Plant:

- Vibrating screens (linear screens, circular vibrating screens, dewatering screens) are fitted with 22320, 22324 and 22326 series self-aligning roller bearings. Featuring a wide clearance design and reinforced sealing structure, these bearings can withstand severe vibration and heavy impact loads, whilst effectively preventing dust ingress;

- Centrifuges (horizontal vibrating centrifuges, vertical scraper centrifuges) are fitted with 22230 self-aligning roller bearings and 30228 tapered roller bearings, which balance high-speed operational stability with heavy-load capacity, whilst meeting the waterproof sealing requirements of wet coal slurry environments;

- Belt conveyor idlers are fitted with 6205 and 6305 double-sealed deep groove ball bearings, whilst drum drives are fitted with UCP208 and UCP210 flanged bearings, meeting the requirements for maintenance-free operation in low-speed continuous operation and high-dust environments;

- Crusher rotors and main shafts are fitted with 22328 and 22332 heavy-duty self-aligning roller bearings, manufactured from high-strength, wear-resistant materials with excellent impact resistance, capable of withstanding extremely heavy impact loads and high-dust operating conditions; 

This collaboration marks a significant milestone for ROOS-LAIS bearings in the coal washing and beneficiation sector in Shanxi, and serves as a vivid example of deepened cooperation between an international premium bearing brand and a major domestic coal enterprise. A representative from the Jinshen Shaping Coal Preparation Plant stated that, following multiple rounds of technical evaluation and operational compatibility testing, the product performance, quality consistency and customisation capabilities of ROOS-LAIS bearings are highly aligned with the plant’s production requirements. Since the first batch of products was put into service, equipment failure rates have fallen significantly and operational efficiency has improved substantially, providing a reliable guarantee for the enterprise to reduce costs, enhance efficiency and ensure safe production.

In the future, ROOS-LAIS Bearings UK will continue to address the key challenges facing the coal washing and beneficiation industry. Leveraging its strengths in research and development, the company will continually optimise product performance and launch a wider range of high-quality bearings designed to withstand the harsh operating conditions of mining sites. It will also deepen its collaboration with major domestic coal enterprises such as Jinshen Energy, utilising its precision manufacturing capabilities to drive high-quality development within the coal industry and support the modernisation of energy equipment alongside efficient and safe production.
