Weiteq WBS belt scales.
Loading managment system.
From the railway:
The inadmissibility of overloading train car over capacity.
The uniform distribution of load between the two wheeled carriages of the car and the uniformity of pouring ore concentrate in the train car in the form of four cones.
Failure to comply with this requirement leads to re-loading "defective" cars, which is accompanied by the re-formation of the train.
From the plant:
Maximizing the effectiveness of using leased from railway rolling stock.
The maximum reduction of production costs, associated with re-loading wagons.
The existing system of loading:
The loading was controlled manually by an operator on the basis of a visual assesment of the amount of concentrate loaded in the wagon. The consequence is a significant underload of the wagons and a large percentage of "defects".
Belt scales were built into the feed conveyor.
Installed on the PC "operator workstation", which:
Using data on the intensity of the flow of concentrate supplied for loading, predicted the distribution of concentrate along the cones, the load uniformity over the wheeled carts with maximum loading of the wagon in general.
Based on promptly updated statistics, reflecting the reaction of the operator and the locomotive driver, the operator was given advance instructions to move the wagon (train) and switch the reverse conveyor through which the wagon is loaded.
The degree of loading of the car increased on average from 90-92% to 98-99%.
The overloading of wagons was practically eliminated.
Cheap solution: material investments were reduced to the cost of belt scales.
