In the equipment manufacturing industry, customer repurchase is a high recognition of product quality and service. The cooperation between a desulfurizer production enterprise in Shanxi and SBM vividly illustrates this concept. From the first purchase of three MTW European trapezium grinding mills production lines to the subsequent repurchase of the same type of MTW European trapezium grinding mill for production expansion after in-depth use, the five-year continuity of trust not only stems from the customer's deep reliance on SBM equipment for its "high stability and long service life," but also confirms SBM core competitiveness of "standing by technology and escorting with service."
Five Years of Trust: Forging the Bedrock of Collaboration
Nestled in the heartland of Shanxi, Taiyuan—an iconic energy industrial hub in China—boasts a dense network of thermal power plants, sustaining a perennial high demand for desulfurizers. A local enterprise, deeply entrenched in desulfurizer production, embarked on its first partnership with SBM by introducing three MTW European trapezium grinding mills for limestone processing. This strategic move culminated in the establishment of a state-of-the-art desulfurizer production line with an annual capacity of 300,000 tons, poised to meet the region’s environmental and industrial needs.
Over half a decade of operation, these three systems have stood as paragons of reliability, delivering high-quality desulfurizers to neighboring power plants with unwavering performance and operational efficiency. With a failure rate consistently below the industry benchmark and instrumentation data adhering strictly to design specifications, they have become the indispensable "cornerstone" of the client’s production ecosystem. The equipment’s ability to maintain peak functionality and data precision after five years of rigorous use is a testament to SBM engineering durability and technological prowess.
As the client’s partner power plants integrated two additional large-scale units, the original production capacity faced unprecedented strain, necessitating urgent expansion to secure desulfurizer supply. Rooted in unwavering confidence in SBM equipment reliability and exceptional after-sales support, the client readily renewed its partnership. This reaffirmation of trust not only underscores a successful collaboration but also heralds a new chapter in sustainable industrial innovation, where performance and partnership converge to power progress.
Material: Limestone
Fineness: 325 mesh
Application: Desulfurizer
Main equipment: MTW European trapezium grinding mill
As the core raw material for desulfurizers in thermal power plants, the fineness of limestone powder is directly linked to desulfurization efficiency and environmental compliance. The client has put forward three core requirements for this capacity expansion:
Leapfrog improvement in production capacity: The annual output needs to reach 300,000 tons, and the equipment must adapt to the flexible demand for further production increases in the future.
Refined quality control: The fineness of the finished product must be strictly controlled at 325 mesh to meet the stringent standards of new-generation desulfurization towers for the reaction activity of raw materials.
Rigid indicators for green production: The equipment must comply with national environmental protection policies and reduce energy consumption and operating costs.
SBM dispatched a professional technical team to conduct on-site inspections, carried out a thorough investigation of the original production line, recorded equipment wear data, analyzed the characteristics of limestone raw materials, and measured the spatial layout of the workshop. It was decided to innovatively adopt a parallel scheme of three MTW European trapezium grinding mills.
MTW European trapezium grinding mill
Technological Iteration Ensures Mature and Stable Equipment: With nearly four decades of experience in mill manufacturing, SBM Machinery has undergone four generations of grinding mill upgrades, maintaining technological leadership and stable equipment operation.
Special Grinding Design for High Efficiency: The curved surface shovel design increases the material grinding area, significantly enhancing powder production efficiency.
Bevel Gear Integral Drive Reduces Energy Consumption: The integral bevel gear drive and resistance-free air inlet volute design improve material fluidity and reduce energy consumption.
Oil Lubrication Prolongs Bearing Life: Both the main shaft drive system and the fan drive system adopt oil lubrication, which offers lower friction and lower oil temperature compared to traditional grease lubrication, effectively extending bearing service life.
New Frequency Conversion Powder Selector for High Precision: The new suspended cage-type powder selector with frequency conversion control enables adjustable and precise fineness, meeting the particle size requirements of various specifications.
The production line was installed and debugged as scheduled, successfully passing the continuous operation test in one go, with excellent finished products far exceeding customer requirements. Up to now, the equipment has been operating stably for eight years, cumulatively producing one million tons of desulfurizers and creating direct economic benefits exceeding 100 million yuan.
From the initial cooperation to the subsequent doubling of production capacity, SBM has witnessed the leap of Taiyuan's desulfurizer industry from extensive production to green intelligent manufacturing through its MTW European trapezium grinding mill.
In the future, with the deepening of ultra-low emission retrofits, SBM will continue to leverage technological innovation and service upgrades to help more enterprises achieve a win-win situation between environmental protection and economic benefits.
