A modern advanced control system can get the maximum throughput from a plant without compromising quality, says Paul Girdham, DSL Systems. It is almost always worthwhile optimising weighing and batching plants because the benefits re-occur day in, day out, year after year. Saving 30 seconds twice an hour works out at an extra 2 hours production per week, saving manpower and energy. All weighing and batching plants have a bottleneck in one area; sometimes this is weighing, sometimes mixing, grinding or other process. In some cases, long conveyors or elevators take time to transport material and then even longer to clean out. In all areas, there are things which can be done to speed up production; sometimes for every batch, sometimes on product change or maybe only at the start of a shift.
