  • A Delegation of Iraqi Clients Visited Our Company for a Field Inspection

    A Delegation of Iraqi Clients Visited Our Company for a Field Inspection

    Recently, a seven-person delegation from an Iraqi company visited our company to conduct technical exchanges and inspect the equipment supply status for the signed natural gypsum vertical mill project. During the meeting, our technical team provided a detailed introduction to the structure and working principle of the vertical mill. Focusing on the customer's concerns regarding product fineness and capacity matching, we elaborated on this topic by drawing on our extensive industry experience and rich track record. Subsequently, using flowcharts and project drawings, we systematically explained the complete process flow from material inlet to outlet. The team addressed the customer's inquiries about warranty, after-sales service, and replacement cycles of wear parts, providing actual operational data from previous projects as reference. Additionally, we introduced the selection and branding of key components. After the meeting, both parties visited the production workshop together to inspect the progress of equipment manufacturing. This exchange enhanced mutual understanding and trust, laying a solid foundation for the smooth progress of the project.
