Definition of closed-circuit grinding A size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit. Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill "(Business in Cameroon) - Coeur d'Afrique", the association of ex-football star Roger Milla, plans to open this year in Douala (Cameroon's economic capital) another recycled plastic waste-based pavement production plant. This is a little more than two years after opening a first plant, in Yaound.

Cameroon - Cameroon - Transportation and telecommunications: The difficult terrain and heavy rainfall in the south have challenged the development and maintenance of an adequate transportation network. The north has traditionally been isolated from the south, and transportation infrastructure is more developed in some regions than in others. A major project was the completion of the first all

Cameroon - Cameroon - Manufacturing: The contribution of manufacturing to the economy grew strongly in the late 20th century, and in the early 2000s it accounted for almost one-fifth of the GDP. The industry is chiefly centred on the processing of the country's various agricultural commodities; significant focus is placed on sugar refining, cotton spinning, tobacco processing, and wood pulp
