Fineness: 250 Mesh
Application: Power Plant Desulfurization
Equipment: MTW European Trapezium Mill

Short-term cooperation relies on products, while long-term win-win outcomes depend on services. During return visits to multiple projects in Shanxi, technicians not only solved equipment operation and maintenance issues but also taught on-site operators skills for daily monitoring and wear prevention, fundamentally improving equipment stability and service life.

SBM return visit team also listened to customer feedback and transformed service experience into data support for product iteration and upgrading, forming a positive cycle of "demand-driven R&D and service-optimized products". This full-process service concept has earned SBM wide recognition from customers in Shanxi.
