Abstract
A container, normally a vehicle such as a hopper car or truck, capable of holding a predetermined maximum weight and a predetermined maximum volume with a bulk material is filled by feeding a batch of the material from a supply to a bin, weighing the batch in the bin, and then feeding the batch from the bin to the container. The volume of the material in the bin is measured the feed of the material is controlled in accordance with the measured volume.
Claims7
A method of filling a container capable of holding a predetermined maximum weight and a predetermined maximum volume with a bulk material, the method comprising the steps of sequentially:
- feeding from a supply into a bin only an amount of the material having a weight considerably smaller than the predetermined maximum weight;
- measuring the volume of and weighing the considerably smaller amount of the material in the bin;
- based on the ratio of the weight to volume of the considerably smaller amount, calculating the weight of the material that would have the predetermined maximum volume;
- thereafter recommencing feed from the supply into the bin until the weight of the material in the bin corresponds to the lesser of the calculated weight and the predetermined maximum weight;
- and
- feeding all of the material in the bin into the container.
