The requirements for raw materials in cement pipe processing can be said to be very strict. The quality of raw materials can be said to directly affect the quality of cement pipes. So what are the requirements for raw material cement concrete in cement pipe processing? Interested friends, let's find out with Wanxin Xiaobian.
In order to ensure the uniform texture of the cement pipe, the uniformity of the cement needs to be mixed and ground with various cement components. It is necessary to separate and grind some parts before mixing, but it is necessary to ensure that the divided and ground cement has the same uniformity as the mixed and mixed cement. It is also stipulated that qualified cement must be stored in a cement bin with a sufficient capacity before leaving the factory. It is not allowed to leave the mill directly after grinding or mixing without going through the intermediate bin. In recent years, new skills and equipment have been selected in terms of pre-homogenization of materials, homogenization of raw meal powder, and dust collection, especially the presentation of differentiation skills outside the kiln, and a new dry production process has followed.
The fine grinding of cement clinker is usually a circle grinding process, which is also a closed-circuit operating system. In order to prevent flying dust during production, dust collection equipment is usually installed. And electric dust collector, bag dust collector and cyclone dust collector are common dust collection equipment in cement products factory.
Today, more than half of the cement in industrially developed countries is used to transport concrete, of which 2-3% is used in cement product factories, that is to say, 80% to 90% of cement is formulated into concrete through successive mechanized production lines. On the one hand, it is produced on a large scale, and on the other hand, the quality requirements for concrete are getting higher and higher. This requires that cement not only has a quality that is suitable for the purpose of use, but also that the quality is uniform and stable, especially in the use function. In terms of water demand and cohesive hardening characteristics, it must be uniform and stable, otherwise it will bring a lot of trouble to the concrete preparation operation, and it will affect the stability of the water content of the concrete, affect workability and quality of the concrete.
From the above, we can see that in the process of making products, in addition to ensuring the quality of raw materials, reasonable dosage is also very important. Therefore, we should pay attention to these problems in cement pipe processing. Avoid formation loss!
