SYSTEM FLOW 

SYSTEM FLOW was developed to enable work with much higher quality standards, both in the production and in the maintenance of these types of systems. The following qualities make System Flow the most complete system on the market. Currently, bag filling systems for cement and mortars use mechanical and pneumatic control systems, with double-stroke pneumatic cylinders that control the so‑called coarse and fine filling stages. Once configured and adjusted for each type of product, the controllers manage the filling process. In fact, these systems are called conventional systems because they use a type of weight control that follows a process directive from the weight controllers available on the market, which in turn are controllers for various types of products and various types of flows. Conventional systems have many types of problems regardless of the origin of the equipment or manufacturer. Conventional systems using pneumatic cylinders cause many issues both in production and in maintenance. In production, this results in overweight or underweight bags due to wear on the cylinders and their components. In maintenance, a specific double-stroke cylinder, besides being expensive, wears out in a short period of time, which leads to weight deviations and almost daily operator intervention in weight parameter settings.

In other words, pneumatic cylinders have a service life that can be considered a “new” period of around 3 months. After this operating time, due to wear (sometimes caused by air supply lines and other times by dust accumulated inside), the cylinders are no longer precise in their final closures and the weights are no longer consistent. A major global problem that all companies have faced and continue to face is undoubtedly the overweight of bags, which represents every year a huge amount of raw material that industries fail to sell and continuously give away to customers because they cannot maintain standardized weight levels. Working with underweight bags, besides being prohibited, is not profitable in production because the rejection of many bags in a single shift increases daily expenses in both energy and labor. Working with overweight bags is even more damaging due to the annual quantity of material wasted—in this case given away to customers—along with increasingly higher transport and energy costs and reduced product quality. It was for these reasons, and based on more than 10 years of daily experience dealing with these problems, that SYSTEM FLOW was developed, with the conviction that it will bring improvements in all areas and guidelines.
