Manufacturing processes conveying system

Negative pressure dust control and pneumatic conveying systems usually have the exhaust fan on the clean air side of the dust collector or filter receiver, especially if the dust or conveyed solids are combustible. NFPA 654, Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids , permits the passing of combustible particulate solids through a fan or blower under certain conditions. See NFPA 654, 2006 Edition,...

The submission of an application conveys an acceptance of certain responsibilities, including the accuracy and the quality of the data as well as the required subsequent reporting and technical commitments for the product and its intended use. To assure the accuracy and quality of the data and information provided in applications, the Act gives the FDA broad authority to inspect pharmaceutical and medical device establishments, including manufacturers and other research testing facilities from which data are derived. Applicants therefore must have documented systems in place for all processes from which data are derived and included... 

A bursting disk is used to protect the reaction vessel. It should be properly rated to ensure that the internal pressure developed during the upset does not exceed the allowance made by ASTM Code Section VHI (or any other pertinent section) for pressure vessels. The actual disk relief area used is 25 to 60% larger than indicated by process requirements (as reported by the disk manufacturer) to account for incomplete bursting of the disk. An emergency relief system (ERS) manifold should be used to collect and convey the effluent material to a train of equipment where it is recovered or properly destroyed to avoid environmental contamination. 

Consideration must also be given to ancillary requirements that will be necessary to support the milling process. Such equipment could include cooling systems, dust collectors. special electrics and conveying mechanisms which will affect capital requirements and day to day operating costs. Dust-free manufacturing capability is a very important requirement in current industry standards. 

Besides the product, today the business is seen in terms of its sustainability at various production chains and it should encompass not only environmental protection, but also social accountability—accountability to the work force as well as to the consumers. A new OEKOTEX Certification System for various production sites can be used by the brands, retailers, and suppliers to convey to consumers that their production is completely sustainable. It guarantees environmentally friendly production processes, and in relation to social accountability, it assures optimum health and safety conditions and a socially acceptable work atmosphere. It apphes to fiber production, spinning and weaving, and finishing facilities, as well as garment manufacturing. As of Jun. 2013, OEKOTEX Certification for production sites was replaced by the Sustainable Textile Production (STeP) Certification label, and its responsibility is with the OEKOTEX Association, with 16 member institutes present in over 60 countries (https //www.oeko-tex.com/en/ manufacturers/concept/sustainable textile production step/step.xhlml).
