System for batch loading coal into railroad cars
A method is described for loading particles into railroad cars wherein a control weight of a railroad car loaded with particles is established and wherein particles are discharged through a discharge end of a weight bin and wherein a weigh gate assembly is connected to the discharge end of the weigh bin having an opened and a closed position. The particles are dischargeable through the discharge end of the weigh bin in an opened position of the weigh gate assembly and are prevented from being discharged from the weigh bin in a closed position of the weigh gate assembly, the railroad cars continuously moving under the weigh bin in a direction of travel. The method comprises the steps of: weighing each railroad car prior to loading particles in the railroad car to determine an unfilled weight of each railroad car; comparing the unfilled weight of each railroad car with the control weight to determine an unfilled differential weight for each railroad car. The unfilled differential weight of each railroad car is stored along with an associated car identification determined sequentially prior to loading. The particular railroad car associated with each unfilled differential weight is uniquely identified. Loading particles into the weigh bin prior to unloading the particles from the weigh bin into the railroad cars; weighing the weigh bin as the particles are being loaded into the weigh bin and terminating the loading of particles into the weigh bin when a weight of particles has been loaded into the weigh bin about equal to and less than the unfilled differential weight associated with the railroad car to be loaded with that unfilled differential weight of particles.
