Presentation of three realizations in elastomers and compounds production
The customer deals with the production and marketing of rubber compounds. This activity, like most of those carried out within this productive sector, involves the emission of specific pollutants such as dust, fumes and odors. For this reason it is very important to have appropriate plants, that can monitor emissions and reduce them.
In this specific situation, the company presented a problem of rubber powders and black smoke emissions from the four mixers used in the production process. Initially, the customer had a suction system composed of an electrostatic precipitator which, however, proved to be unsuitable to solve the specific problems arising from the processing of rubber.
Tecnosida® was contacted to improve the existing suction system, creating a plant in line with the customer’s needs and compliant with current legislation.
Following an appropriate technical inspection (a normal activity executed to assess the specific situation of the production line, of the equipments in use and to get technical data and measurements), Tecnosida® proposed the construction of a plant able to treat the emission flow. The plant consists of:
The plant is also equipped with triboelectric probe, inverter and pressure stabilizer. The first, placed on the exhaust pipe, allows to monitor the emission of powders into the atmosphere. Instead the inverter has been placed inside the electrical panel and allows to monitor the energy consumption of the suction system; while the pressure stabilizer, through the inverter, keeps the pressure constant.

Our customer is a company that, in various production plants, produces a wide range of elastomers: compounds in synthetic rubber (EPDM, NBR, CR, HNBR, ACM, AU, ECO, EU, CSM, AEM) and natural rubber ( NR, SBR, SN) both black and colored, silicon compounds and fluorinated rubber. The company also produces customized solutions for the high-tech moulding industry.
The customer contacted us and requested the design, implementation and installation of a suction system able to manage three lines with variable operation and loading, equipped with various mixers with segregated (and non) functioning operation. The polluting load consists mainly of powders, some of which with binder behavior, and must be treated by a single centralized filter.
Tecnosida® accepted the request and performed a preliminary technical inspection to identify the critical points. They are linked to the high number of release points (over 20), the particular geometry of some production machines, the types of powders to be treated and the possibility of sudden changes in flow rate due to opening/ closing of some points of the production line.
The solution that was then proposed focuses on four points:
Tecnosida® plant has been realized in compliance with the BAT (D.MF.01) and has allowed to reduce emissions within the limits established by law, thus resolving the problem of the customer.
The customer is an Italian company that operates in the rubber industry and deals with the production and marketing of customizable pipes and compounds.
This type of processing involves the emission of rubber powders, so the company decided to contact Tecnosida® requiring the construction of a plant able to solve their problem. The system must be placed at the service of the production machines: three mixers and a calender positioned in the dosing department and in the production of the compounds.
Following careful technical inspections, Tecnosida® proposed the realization of an aspiration system consisting of localized suction systems and the Dustdown® self-cleaning bag filter. The localized suction represents the first stage of the abatement system, as it allows to capture pollutants directly at the source. It is composed of two extractor hoods placed at the service of an open mixer and a calender, two articulated and self-supporting suction arms made of aluminum and a series of vacuum cleaners for the capture and removal of dust from specific operating areas . This devices are very important to avoid dust dispersion and, consequently, to heal the working environment by protecting the health of the operators.
The flow of air aspirated by the devices described above is then conveyed and treated inside the Dustdown® filter. It is made of sturdy galvanized carbon steel sheet, is equipped with a 260m3 filtering surface and is complete with a suction unit and other elements that guarantee optimal operating efficiency. Furthermore, the filter is produced in compliance with the BAT of the DGR / 2913943-2003 relating to dust emission.
Tecnosida® realized the system in compliance with current regulations and paying the utmost attention to environmental protection. The electrical panel is in fact equipped with inverter for monitoring and reducing energy consumption; atmospheric emissions comply with limits established by the Italian Legislative Decree 152/2006.
