I. Customer Background 

Customer Name: A large non-metallic mineral processing company in the Central China region 
Processing materials: Limestone (with a Mohs hardness of around 3) 
Product application: Desulfurization in power plants, additive for building coatings 
Original problem: The customer's original old-type Raymond grinding machines had high energy consumption, severe dust pollution, and poor uniformity of product fineness, which failed to meet the strict requirements of high-end coating customers. 

II. Solution 

After conducting on-site inspections and material tests, Shanghai Cronus equipped it with the CRRM series integrated grinding powder production line. 
The core reasons for equipment selection: 
High stability: The Cronus series is equipped with reinforced reducers and maintenance-free grinding roller assemblies, enabling 24-hour continuous operation. 
High precision classification: Equipped with a new generation of turbine classification system, the fineness of the finished product can be freely adjusted within the range of 80 - 600 mesh. 
Energy conservation and environmental protection: A fully negative pressure closed-circuit circulation system is adopted, combined with a high-efficiency pulse dust collector. The workshop basically achieves no dust leakage outside. 

III. Project Implementation Process 

Customized solution: Considering the slightly high moisture content of limestone, the Cronus system has been equipped with an online drying and balancing device. 
Fast delivery: The modular design enabled the equipment to be installed and debugged on-site within just 15 days after arrival. 
Intelligent Training: The technical team of Cronus provided operation training on the PLC intelligent centralized control system for the client's operators. 

IV. Comparison of Operational Outcomes 

Indicator / Project	Traditional Raymond Mill (Old Equipment)	CRRM Series	Improvement
Hourly Output	4-5 tons / hour	8-12 tons / hour	Approx. 100% ↑
Product Fineness	325 mesh (Pass rate 85%)	325 mesh (Pass rate 98%)	More Uniform
Unit Energy Consumption	High power consumption	Energy saving approx. 20%-30%	Significant Cost Reduction
Noise Control	> 95 dB	< 80 dB	Complies with Environmental Standards

 

V. Customer Evaluation

"After switching to Cronus, the most immediate impression is 'stability'. Previously, the old grinding machines always had to be shut down for grinding drum maintenance. Now, they are basically inspected only once every half a year. Moreover, due to the extremely concentrated distribution of the finished powder particle size, the unit price of our desulfurization powder has also increased significantly in the market." —— Mr. Wang, the technical director of the company
