You will find two fundamental needs on concrete batching plant material proportion. The first is batching precision and yet another is average. For batching precision, weight weighing technique is more precise compared to volume weighing method, and also the two reasons can explain it.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China.

As everyone knows Sicoma planetary concrete mixer, the proportion water and cement is definite, however the proportion might be impacted by weather, temperature and atmosphere. Expansion and contraction, or wet weather could make volume unmanageable, that will cause a mistake. However, the precision of weight weighing method could be made certain generally, therefore we usually adopt this process to verify proportion. concrete batching plant Second may be the influence of gravel. Gravel is definitely an indispensable material in concrete batching. It's always unscientific to weigh the level of gravel. Since the level of gravel could be affected greatly by its place way. Therefore cement batching plant, it's more precise to consider the load weighing method. Another factor may be the precision of single weighing. As it is absolutely accurate, we ought to take weighing for a lot of occasions if condition enabling. Thus the end result could be more accurate. Therefore, the precision of concrete mixing plant material proportion is recognized by multiple weight weighing method, as opposed to the single volume weighing way.
