Loading of various bulk solids materials is one of the important
aspects of overall bulk material handling operations. Various devices are
available for particulate bulk material loading. Telescopic chute or telescopic
loading spout is a device that helps in loading free flowing bulk solids
material. These are also used for loading bulkers and trucks, ships and barges
and also for stock piling.

Downwardly suspended discharge chutes are used to load bulk
solids materials. Telescopic chute is a special type of loading chute that has
the capacity of retracting and expanding. The material freely falls through the
discharge chute in a stream influenced by gravitational force until it gets
deposited in the vehicle forming a stock pile. The bulk material also contains
dust and other foreign particles which gets carried along with the bulk
material.
While the material is getting loading, the dust that is
generated needs to be vented. A bag filter can be used for this operation. An
integral bag filter with reverse pulse jet mechanism can be used for effective
dust control.

There are many disadvantages associated with the dusting that is
generated while the loading of bulk material. First and foremost is that the
dust is harmful for the environment and causes air pollution. Also it is
harmful for the health of the people in the vicinity of the dusting area. The
lungs of the people inhaling the dust laden air gets affected negatively and
may cause serious health problems depending on the material and type of dust.
The workers need to wear protective masks to avoid this problem. However the
workers may not be sensitive towards their health and avoid using masks as they
find it inconvenient.
Secondly the dusting causes the violation of the norms laid down
by government and may attract penalties which adds up to the costs. Governments
lay down the acceptable levels of dust particles in the air and the norms need
to be followed.
The visibility in the area of dusting is also another problem.
Poor visibility can result in accidents and serious injuries to the employees.
In case the dust is explosive the dust control becomes all the more essential.
Hence telescopic chute or telescopic loading spout is an important dust control
equipment for loading of bulk solids material.
