Tianjin Cement Pipe Factory: Requirements for Cement Concrete in Pipe Processing (Rongfeng)

To ensure the uniform quality of concrete pipes, the uniformity of the cement requires the mixing and grinding of various cement components. It is permissible to grind certain parts separately and then mix them, but the cement ground separately must maintain the same uniformity as that mixed together. It is also stipulated that qualified cement must be stored in a cement silo with sufficient capacity before it is shipped out, and it is not allowed to be shipped out directly without an intermediate storage after grinding or mixing. In recent years, new technologies and equipment have been adopted in raw material pre-uniformization, uniformized conveying of raw meal powder, and dust collection, especially with the emergence of off-burner decomposition technology, which has led to the birth of a new dry production process.

The fine grinding of cement clinker typically employs a circular flow grinding process, also known as a closed-circuit system. To prevent dust from飞扬 during production, dust collection equipment is usually installed. Electric dust collectors, bag dust collectors, and cyclone dust collectors are commonly used dust collection equipment in cement product factories.

Nowadays, over half of the cement in industrialized countries is used for conveying concrete, with 20-30% used in cement product factories, meaning that 80-90% of the cement is mixed into concrete through continuous mechanized production lines. On one hand, there is large-scale production, and on the other hand, the quality requirements for concrete are increasingly stringent. This necessitates that cement not only meets the quality standards for its intended use but also maintains uniformity and stability in quality, especially in terms of functional aspects such as water demand and setting characteristics. Otherwise, it can cause numerous complications in concrete mixing and affect the stability of concrete moisture content, workability, and overall quality.
