Er ~ our company uses a laser coal winder to measure ~ but the cost of the machine is too high, and the technology content is high ~ and it is impossible to measure once a day ~ only for the first time, and then we will strictly collect the data of the warehousing documents to calculate the remaining inventory ~ this is the most helpless way ~

In this case, it seems that we can only get one coal tray instrument ~ our department spent more than 200 thousand to buy it ~ hehe ~ it's a bit like killing a chicken with a knife ~

In fact, the average coal pile boss doesn't even know how much coal he has ~ After all, it's not easy to weigh, and the heat is evaporating every day, which makes the weight drop ~ Either you can calculate the approximate weight through the documents in and out of the warehouse ~ Or you can cut a regular figure in your mind and then use a ruler to pull several lengths to calculate the volume. This method needs experience accumulation ~

The volume problem is difficult to solve ~ and the density is more troublesome ~ the quality and type of coal, the stacking environment and the storage time will all affect its density ~

So it's really unrealistic for you to measure the exact weight of that pile of coal ~
