1, check the accuracy of scales under static powder

(1).checking and cleaning up all the soft connections (including screw machines and scales, scales with the host connection and ventilation bellows) slack enough. Press the soft connection inside the bag by hand, and it can be recessed 3 ~ 4cm in four weeks. The soft connection will be moisture if it is wet, so we need to clean in time. And if we use ventilation for a long time, it will be easy to be hard, so we also need to make sure if it also has scalability.

(2) Confirm the hopper body without any interference from the outside world, and clean all the air ducts and bottom of the sensor.

(3), Inspection with enough weight scales. "Enough," that means it is full production of cement, two side machine less than 600KG, 3 square machine less than 800KG. Steps: first with F1.5 cleared the instrument and return to normal state to 100KG units to add weight on the scales, scales recorded test data. Weights placed at the center position as the center of gravity on time scales.
