Custody of cement concrete mixing plant Precautions

Concrete concrete mixing plant is essential for the production process is one of the important elements , as one of important raw materials, mixing cement custody is also an important task in the custody process , there are many points to note , for you to take off today make a summary.
1 , moisture-proof waterproof cement work . Cement storage and transportation biggest threat so that rain and moisture , especially in the South more rain , so after the initial installation, carefully check the tightness of the entire pathway , from the principles and structure of the moisture and rain on the handling , to eradicate troubles , it is very necessary. If the design is not very tight, cement silo lower valve , and screw machine screw machine interfaces as well as the middle of the interface and the connection with the cement weigh hopper are likely to be rain and moisture intrusion , resulting in reduced performance and cement agglomeration phenomenon. In this case , one should try to strengthen the seal on the other hand to avoid retention of cement screw conveyor and weigh hopper .
2, the device design and maintenance . Cement weighing hopper upper material inlet and outlet connections screw machine , not too tight , nor too loose , too tight will affect the accuracy of the scale , too loose affect feed unobstructed ; concrete mixing batch plant weighing hopper feeding with the host the mouth of the connection process is bad, because the accumulation of material and solidified lumps formed on the supporting role in causing hopper , scales of measurement may be inaccurate ; hosts cement feed passage because by the influence of water vapor in the host , the channel easy to stick the wall of cement, the cement feed channel is getting smaller , affecting the speed of feeding , and the cement is not easy to clean, feed , and therefore the cement weigh hopper and down the channel be inspected and cleaned regularly to ensure accurate measurement of cement .
