The ever increasing number of schools in Nigeria and other developing countries enlarges the demand and consumption of chalk. To meet this demand, it is imperative to align the demand with production. The aim of this work is to design, construct and test a chalk moulding machine with high level of local content and competitive produce. The constructed moulding machine was able to produce seventy-three packets of chalk, each packet containing eighty sticks of chalk, with an efficiency of seventy-six percent. The chalk produced writes smoothly and is easily erased.
