Production is carried out in electronically variable dispersers, on twenty raw materials used by the startup in the plant.
The storage park, located near external communication routes, in a peripheral area already designed for subsequent expansions and extensions, is of strategic importance.
The storage silos also deserve special mention, with a vertical cell with a capacity of 43 m3 and a maximum height from the ground of 13 meters, as well as a mass of the complete structure of 4 tons.
The functional diagram, accompanied by a principle diagram (which includes the various phases into which the process is broken down) and a running diagram (which shows the indications for its operation), is structured into a H2O line, an additive dosing system, a resin distribution and powder transfer circuit, integrated with the appropriate containment tanks, with a centrifugal filtration and suction system with an air flow rate of 3,500 m3/h, and finally a weight dosing machine for packaging the finished product.
Numerical analysis and the finite element model (FEM) allowed Idealtec to give static and seismic characterization to the structure according to the calculation criteria and indications provided by the European standards for structural design – with particular reference to the requirements of mechanical resistance, safety against overturning, sliding, collapse due to horizontal actions, and the capacity to dissipate the energy developed. Also crucial is the joint evaluation with the customer of the foundation elements, capable of resisting the effects of the shear actions, calculated at the base of the structure, without significant permanent deformations.
The materials are sent to the silos from the tankers by pneumatic loading and are extracted by means of screw conveyors. The interception and regulation of the flow is entrusted to the rotary valves, while the weight measurement is entrusted to the underlying load cells, which guarantee the selected flow rate values.
The geometry and the discharge section of the hoppers, influenced by the flow regime and the product discharge dynamics, are decisive in ensuring uniform emptying of the silo: they have an appropriate conicity (in relation to the friction coefficient of the material) and a fluidized bottom, so as to guarantee a constant and regular flow of the product, with the exclusion of the formation of cohesive arches, segregation and consolidation of the material, incomplete emptying, erratic or insufficient flow.
The material packaged in bags and big bags is instead delivered to the aspirated bag cutting cabin, via a duct connected to the centralized dust abatement system, and to the six FIBC emptying stations, arranged in parallel – which ensure the continuation of the production process even if one or more supplies fail.
These stations – given the appropriate checks of the relative safety coefficients (stress components, operating loads, service limit state) – are also equipped with load cells with accurate measurement capacity, and screw conveyors that feed the transport circuit in a controlled manner.
Thanks to the direct thrust in the aeromechanical conveying line, the composite materials advance along a mixed path, consisting of horizontal and vertical sections, which converges in a single distribution duct, whose flexible transmission organs hit and drag the product to the unloading point.
The material thus reaches the dispersers by gravity, set in the deck with an overhanging gallery – which flanks the equipment and facilitates operators in inspection and maintenance operations at height.
The final product is taken to the discharge point without introducing air into the receiving tank, with the consequent (and advantageous) exclusion of filtering baffles for the separation of the solid transported from the entraining gaseous fluid.
The mixing of the fluids with the solid products occurs using cowles agitators, while the effectiveness of the solvating action is guaranteed by the automatic valves located at the inlet of the dispersers.
The centralized monitoring of the operating conditions and set-point values is achieved using a PLC, with a graphical interface, which makes all the logical sequences in progress available and visible in real time, ensuring reliable planning, command and control of the plant’s performance.
