HISAN High Chromium Wear Resistant Coal Chute features a curved streamline design that completely eliminates coal blockages, dust emission and heavy impact. Made of high-chromium wear-resistant material with chromium content over 35% and hardness above HRC 60, it delivers greatly enhanced durability. HISAN curved coal chutes offer a service life of more than 5 years, significantly cutting costs and boosting efficiency to put an end to frequent pipe replacements.
Colleagues engaged in coal transportation at coal mines, thermal power plants and ports—are you constantly troubled by recurring problems with coal chutes?
Conventional straight coal chutes leave much to be desired. Frequent coal blockages force shutdowns for manual clearing, disrupting production and posing safety hazards. The pipe walls wear out rapidly under continuous scouring by coal, requiring replacements every few months and driving up operation and maintenance costs. Massive coal dust escapes during blanking, failing environmental compliance standards and endangering workers’ health. In addition, the strong vertical impact of falling coal easily damages downstream conveyor belts and other equipment.
These four major issues have long plagued the coal conveying industry. Custom HISAN high-chromium wear-resistant curved coal chutes deliver an all-in-one solution to eliminate all these troubles!
✅ Curved streamline design eliminates blockages, dust and heavy impact
Abandoning the traditional straight-tube structure, HISAN customizes curved flow channels in line with material flow rules. Structural parameters are adjusted according to actual working conditions including blanking height, material flow rate and particle characteristics. Coal slides smoothly along the pipe wall to fundamentally prevent coal accumulation and blockages. The design also guides induced airflow to suppress dust emission and buffer falling impact, protecting conveyor belts and auxiliary equipment to cut equipment repair expenses.
✅ Premium high-chromium wear-resistant material for drastically extended service life
These custom chutes are fabricated from 12+12mm surfacing wear-resistant plates with a chromium content of over 35% and hardness exceeding HRC 60, far outperforming ordinary wear-resistant steel plates and offering several times better anti-scouring performance against persistent coal abrasion. Welded from high-chromium composite wear-resistant steel plates, the finished products feature exceptional structural stability and seamless compatibility with existing conveying systems, preventing material jamming caused by structural deformation from both structural and material perspectives.
✅ Significant cost reduction & efficiency growth, eliminating frequent replacements
Standard coal chutes only last 3 to 6 months and demand frequent shutdowns for maintenance and part replacement. In contrast, HISAN curved coal chutes boast a service life of over 5 years, drastically cutting losses from production halts, spare part procurement and manual maintenance with outstanding overall cost performance.
Manufactured by HISAN, these high-chromium wear-resistant curved coal chutes have been widely deployed in numerous coal mines, thermal power plants and port coal transshipment projects. Proven reliable and durable through field applications, they stand as the top choice for coal enterprises to upgrade conveying systems while cutting costs, ensuring operational safety and meeting environmental protection requirements.
