Construction of a glass sorting plant

The Coriano plants were built for the purpose of separating impurities consisting of foreign fractions present in the separate collection of the vitreous fraction. These impurities are identified as metals, plastic, paper, wood, infusibles, unbreakable glass, etc. The construction of the plant is aimed at obtaining glass output that meets CoReVe specifications. The construction of the plant was conducted in record time: four weeks on site and two months of supplying the machinery since the project was approved to see the plant up and running.

The project consists of the components summarised below:

• vibrating channel with an 8 m³ hopper, installed to feed the line with a robust machine that does not create clogging and crushing problems
• backhoe loader conveyor, delimited to prevent access under the machine during operation, given the hazardous nature of the material handled
• sorting belt fitted with speed variator that can be controlled by the operator if the line requires speed regulation or there are sorting needs, without causing stoppages to the line
• Safety rope that allows the machine to stop along its entire length
• Pre-fabricated sorting cabin with 4 sorting workstations
• stainless steel connection belt being located under the deferrization belt
• magnetic sorter with hoisting system (electric hoist)
• glass outfeed conveyor

In the realisation of the sorting cabin, particular attention was paid to the ease of use of the technology for the operators, more than containing costs for the client. The control of the system is managed via plc and touchscreen inside the cabin itself. Even the air conditioning system has a control command to customise its performance.

Another aspect taken into consideration during the construction of the plant was the breakage of glass bottles during in-line processing. Special resistant rubbers were applied at strategic points to cushion impacts and limit glass breakage for reduce the potential risks from breakage.

The vibrating channel, used as a loading hopper, is the first innovation in this project that was accepted by the client, a true example of efficiency.
