Models of small concrete mixing plant include HZS25, HZS35, HZS50, etc. According to the feeding way, such small-size mixing plants can be divided two groups: manual feeding and automatic feeding. Some customers tend to choose manual feeding to save cost. However, manual feeding presents many disadvantages in reality.   

In the first place, manual concrete mixing plant is not computer-controlled. As a consequence, the measurement of admixture is very like to be incorrect, which results in the instability of concrete quality. This situation can be completely avoided in full-automatic concrete mixing plant.

In the second place, when batching process is operated by human labor, it is prone to cause unnecessary material waste of water, cement, fly ash, or admixture, etc. In addition, worker salary is also large sum of money. That is, adopting manual feeding, companies save equipment cost, but the labor cost increases.

Finally, large area of dust in the concrete mixing plant does serious damage to both the environment and related workers.

So, it can be inferred that the computer-controlled full-automatic concrete mixing plant with electronic weighing is more convenient and efficient than the manual feeding mixing plant. Henan Huaning Machinery Equipment Co., Ltd produces energy-saving full-automatic concrete mixing plant with high quality and high efficiency.
