In the equipment manufacturing industry, a customer's repeat purchase is a high recognition of product quality and services. The cooperation between a desulfurizer production enterprise and Zenith is a vivid embodiment of this concept — starting from the initial purchase of 3 MTW European Trapezium Mills production lines, to the re-purchase of the same type of MTW European Trapezium Mill for capacity expansion after in-depth use. This 5-year-long trust not only stems from the customer's deep reliance on Zenith equipment for its "high stability and long service life", but also confirms the core competitiveness of Zenith, which is "based on technology and supported by services".

An enterprise deeply engaged in the field of desulfurizer preparation, upon its first cooperation with Zenith, introduced three sets of MTW European Trapezium Grinding Mills for limestone processing and invested in building a desulfurizer production line with an annual output of 300,000 tons.

Over a 5-year-long operation cycle, these three sets of equipment, with their stable performance and efficient output, have continuously supplied high-quality desulfurizers to nearby thermal power plants. The equipment failure rate has long been lower than the industry average, and the instrument monitoring data has consistently met the design standards, making them the "stabilizing force" of the customer's production line.

After 5 years of operation, the original equipment still maintains stable performance and accurate, reliable instrument data, fully verifying the durability and technical advantages of Zenith equipment. Later, as the power plants supplied by the customer added 2 new large units, the existing production capacity could no longer meet market demand, and the customer urgently needed to expand production to ensure the supply of desulfurizers. Based on its recognition of Zenith's equipment performance and after-sales service, the customer did not hesitate to choose Zenith again.

Processing Material: Limestone

Finished Product Fineness: 325 Mesh

Finished Product 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 related to desulfurization efficiency and compliance with environmental protection standards. The customer put forward three core requirements for this capacity expansion:

Leapfrog Capacity Improvement: The annual output should reach 300,000 tons, and the equipment must be flexible enough to adapt to further capacity increases in the future.

Refined Quality Control: The fineness of the finished product must be strictly fixed at 325 mesh to meet the strict standards for raw material reaction activity required by the new-generation desulfurization towers.

Rigid Indicators for Green Production: The equipment must comply with national environmental protection policies to reduce energy consumption and operating costs.

Shanghai Zenith dispatched a professional technical team to the site for investigation. The team inspected the existing production line, recorded equipment wear data, analyzed the characteristics of limestone raw materials, measured the plant space layout, and finally decided to innovatively adopt a parallel connection scheme with three MTW European Trapezium Grinding Mill.

Bevel Gear Integrated Transmission for Reduced Energy Consumption

Thin Oil Lubrication for Extended Bearing Life

New Variable-Frequency Powder Separator for High-Finished Product Precision

The production line was installed and commissioned on the scheduled date, passed the continuous operation test in one go, and the finished products were of excellent quality, far exceeding the customer's requirements. Up to now, the equipment has been operating stably for eight years, with a cumulative desulfurizer output of one million tons, creating direct economic benefits of over 100 million yuan.

From the initial cooperation to the subsequent doubling of production capacity, Zenith, with its MTW European Trapezium Grinding Mill as the carrier, has witnessed the leap of the desulfurizer industry from extensive production to green and intelligent manufacturing.
