The bagging of dry mortars and cement-based building products can be considered one of the most smashing Concetti achievements: over the last few years, our Company has in fact given to numerous Clients the possibility to change from pre-made valve bags to PE bags obtained from a tubular reel, preventing their batches to suffer any leakage and ensuring a cleaner and healthier environment for the operators, while still ensuring a nicely pillow-shaped bag and a very stable pallet.
It is a successful “packaging revolution” that the Concetti company didn’t miss a chance to promote and lead.
Thanks to our special auger feeding system, produced with a higher thickness and anti-abrasive coating to guarantee a longer durability and effectiveness, these products, often a blend of cement, little stones, gravel and sand, are fed to our one or two net weighers (NET/CC) and from there into the bag-holder of our Continua FFS machine.
In this type of machine, along with the usual vibration devices and option for corner sealing to improve the products distribution inside the bag, we find the Concetti patented handle-maker device, capable of creating one or two handles on the bag short sides to allow a better transportation and manipulation of the bag.
The full bags, ranging from 10 to 40 kg, are conveyed and treated along the way thanks to some specific Concetti vibrating and pressing devices to the palletising unit;
For this family of product, the ideal choice is a fed-from-above palletiser complete with bag flatting units and bag orientating device.
For the Clients who need to stick with flat or gusseted open-mouth paper bags, the Concetti solution for concrete premixes and dry mortars isn’t less brilliant: our IMF bagging machine class can work bags ranging from 5 to 20 kg, featuring several different closing systems and remarkable capacities, even if the use de-aeration probes is required.
The final result of this innovative packaging process has turned out to be so brilliant that some world-leading industrial Groups like Ameren, Hanson, Remix and Draco have decided to add a combination of several Concetti automatic bagging lines to their production process, enjoying the advantages of a top-level technology and the possibility to work in a cleaner and tidier environment.
