Requirement of Innovation in the Design of Relescopic Chute for Dust Free Loading of Bulk Solid Material into Containers

This article provides information regarding importance of innovative design of telescopic chute for dust free loading of bulk solid material into various containers. The trends are changing, there are rising concerns about dust emissions. Awareness and emphasis about dust control has increased. With clean air and dust free working conditions becoming a top priority, telescopic chute has become an integral part of the bulk handling systems. Telescopic loading spout is widely used for handling of bulk solid material in high volume for loading them into like trucks, ships, locomotives, barges, etc.

The equipment is used for loading of free flowing solid bulk materials with improved process for loading such materials into closed containers which have small loading ports or opening.Wide variety of free flowing solid materials are stored and transported loose bulk form.  Typical examples of fine solid particles in agglomerated form include fly ash, chemicals and pigments, carbon black pellets, etc. Since such materials are stored and transported in bulkers which are completely closed, access to these container is only through small ports or openings.

Due to the type of applications where telescopic chute is used, there arise certain problems and challenges which needs to be address through innovation. As for example, when such powdered bulk solids are loaded into closed containers with small ports, the flow of material is not like liquid. The material do not get filled evenly but forms a conical heap into the container depending on the property of the bulk material. This creates void spaces around the peak of the conical heap within the container body.

Innovative design of telescopic loading spout can help in completely filling the container by filling the void spaces. This will be appreciated by the industry. Partially filled hopper cars or containers are economically inefficient. Also where there is a bottom ceiling of weight for freight rate calculation, companies suffer unnecessary losses due to under weighting which can be avoided by fully filing the containers. Hence innovation is of utmost importance for design of effective telescopic chutes which can help in loading free flowing materials efficiently into the closed containers.

Another problem is encountered when the bulk material is loaded into railroad covered hopper car. Too much dusting during loading can cause large quantity of dust to stick to the walls of the hopper car. In such a case unloading the car becomes extremely laborious. An effective design of telescopic loading spout can help in containing the dust effectively, thereby helping to solve this problem.

Many a times the bulk material handled in friable and it can cause damage to the material if the material freely falls from a certain height. There are innovative designs available for telescopic chutes that can handle such problems.

Certain bulk materials are hazardous and the dust produced by loading such material can cause explosions. It is imperative that when such materials are loaded from silo into the trucks or containers the propagation of dust needs to be as minimum as possible to avoid the accident caused due to such materials. In present scenario such concerns need to be addressed at any cost considering the safety norms and standards that the companies need to follow through regulations of governments. Effective dust control by telescopic chute can go a long way for such critical problems.

One last issue that pertains to loading of bulk material is the wide variety of cars into which the material is to be loaded for transport. Cars of various sizes are available. Innovative design of telescopic loading spout can help to get adapted to such various sizes of cars or containers.
