China's bellows pump manufacturing industry has advantages in improving the transportation of cement powder. Bellows pump is a widely used conveying equipment for various powdery materials. Its working principle is to convey materials from one place to another through pneumatic force. The characteristics of bellows pump are simple structure, easy operation, low maintenance cost, dust-free transportation, and it is suitable for various harsh environments. In the short-distance transportation of cement powder, bellows pump can effectively prevent dust pollution and protect the environment.

In terms of environmental protection, the important role of bellows pump in short-distance transportation of cement powder in Iran is self-evident. It can effectively reduce dust pollution, protect workers' health and the safety of the surrounding environment. In addition, it can improve production efficiency and product quality.

China and Iran have close economic and trade relations. China is one of Iran's largest trading partners, and the trade volume between the two countries continues to grow.
