Batch Controller – Truck loading and big bag dosage of freeﬂowing bulk solids. When loading bulk in trucks or other means of transportation, in many cases it is only possible to weigh the product after loading has been finished. To fill the truck at an optimal degree or to prevent a container from overloading a simple way of weighing is required. The Batch Controller combines pneumatic slider and baffle sensor in a very compact design. Because of that, it can easily be installed between loading hopper and truck inlet. It provides preselection and monitoring functions which distinctly simplify loading processes. Furthermore charging and discharging of big bags with simultaneous weighing is possible. The Batch Controller requires full product stock above the slider and free flowing products.
