Loading bulk solids with explosive characteristics

TBMA has serviced the dry bulk industry for decades, focusing on the loading and conveying of all kinds of industrial bulk goods. The company has thereby gained
a vast experience within industrial bulk handling. This experience is constantly being put to use in developing new solutions which meet the demands of authorities
and users for functionality, quality and environment
friendly operation. The solutions have been developed on the basis of a product range consisting of various types of loading chutes for open and closed loading of dry bulk materials into e.g. trucks, rail wagons, containers, ships and for stockpiling. The loading chutes are sold under the brand name Moduflex.

Dust is an important issue when handling various bulk solids such as e.g. grain, paper, plastics, sugar, wood or other organic material, as it is the cause of many accidents in the work place. Not only because of the dangerous effects on the human body working in a dust laden area can have, but more because the storing and handling of these products always contains a high explosion risk that might cause destruction of buildings and production equipment and in worse case - loss of human life. However, recent years increased focus on dust emission with the implementation of the ATEX directive has proven to have a preventative effect.  

The correct design of transport equipment with regards to limiting the dust emissions is particularly important. The demands for explosion proof equipment imply that all supplied mechanical parts and electrical components are special constructed for application in equipment installed in high explosive risk areas. All precautions taken endeavour to create a safe working environment. Beyond the direct improvement of the working environment by bringing down the amount of airborne dust, the risk of creating an explosive atmosphere outside of the transport equipment is furthermore reduced.

Meeting ATEX demands
Through the years, TBMA has gained a great deal of experience when it comes to supplying loading and conveying equipment in compliance with all international regulations. The company has a standard working policy to insure that the supplied equipment is in compliance with the rules laid down in the ATEX-directive. Not only are the assembled parts scrutinised but the complete working unit where all factors including the build-up of static electricity and surface temperatures are taken into consideration.

Key words in connection with ATEX related equipment is approval, marking and documentation, where the manufacturer’s declaration plays a key role. As a part of the approval of the Moduflex loading chutes, is the compilation of a comprehensive technical dossier, which contains considerations concerning health and safety aspects relevant to the loading chutes in relation to the ATEX-directive.

Due to the factors mentioned above TBMA has already supplied several Moduflex loading chutes manufactured for plants where dust control, hygiene and compliance with the ATEX-directive are an essential prerequisite for the delivery. The Firma Liucija in Lithuania is a fine example with 8 Moduflex loading chutes of the type HDF400. Each loading chutes is fitted on a positioning unit for optimal manoeuvring when loading rail wagons from the same silo battery. The chutes will be used for loading soya beans and raw sugar, and due to the nature of the product the loading chutes are provided with explosion proof components in accordance with the ATEX directives. The chutes are equipped with a 13,5m³ built-in filter and a FlexPositioner

FlexPositioner; motorized unit for optimal positioning of the loading chuteEach loading chute is mounted under a FlexPositioner. This is a motorized unit for optimal positioning of the loading chute. This feature reduces loading times and increases safety. Now the train wagons do not have to be  positioned exactly under the loading chute. Instead the chute is automatically brought into position and then connected by remote. Especially with long trains, this leads to significant time savings
