Abstract – Blackboard and chalk piece are an indispensible part of a classroom, no matter how smart our classrooms have become. Erasing the board with a duster generates a fine suspension of chalk dust in the vicinity of the board, which is constantly inhaled by the teacher as well as the students near the board. Though this doesn’t appear serious, prolonged inhalation will result in breathing trouble. Hence automation of the board erasing process is attempted along with a mechanism for suction, which suppresses the dispersion of chalk dust in air. It is planned to implement this in our college class rooms on a step by step basis.
When we rub the board,we push the duster against the blackboard to rub. The duster attracts the chalk particles and pulls them to it and in this order rubs the things written on it. Hence it is both push and pull.Jun 5, 2019
