Most quarries use static or dynamic weighing systems to manage the quality of the products they produce and to measure the quantity of material or finished products they deliver to their customers.
PRECIA-MOLEN, as a long established manufacturer of weighbridges, has utilised its wealth of knowledge of the aggregates industry to constantly develop and expand its range of weighing products to include integrating belt scales, on-board weighing systems, volumetric hatches, weighing conveyors and associated management and control software programs.
| APPLICATIONS | PRODUCTS | |
| Management of the shipping of materials to customers | Fixed or site weighbridge / truck input/output management software / driver terminal / acces control / barrier / two-colour indicators / solar power supply |  |
| Production management: determination of circulating load, regulation of supply to crushers and screens | Throughput controller with trend indicator / fine accuracy multi-line scale between primary and secondary crushers / production control software |  |
