In this example, the crushing and grading host used by the customer is CSM (Air Classifying Mill)
We will recommend more suitable host equipment according to your actual needs, such as Pin Mill and Air Classifier.
The total installed power is about 109.2KW
Feeding system 2.2KW, mechanical pulverizer 55KW, grading rotor 15KW, centrifugal fan 37KW
Process
Sulfur crushing and grading equipment is specially designed and customized according to the actual needs of customers. The system adopts an integrated design system of automatic control, crushing and classification, and the technology has reached the international advanced level.
The material enters the pulverizer through the quantitative feeding system, the pulverized sulfur powder enters the classification area, and the qualified products are collected and packaged. After the nitrogen gas passes through the induced draft fan, it enters the secondary air outlet of the main machine of the pulverizer after being filtered and cooled to complete a cycle.
The PLC strictly controls the oxygen content in the whole process. When the oxygen content exceeds the standard, nitrogen is automatically added to ensure the safety of the entire crushing system.
The system has a clear process route, compact system design, good stability, high efficiency and energy saving, convenient equipment operation and maintenance, less peripheral supporting equipment, reduced construction scale, and high cost performance.
