Agricultural lime is used to correct soil acidification, and is found in many regions in southern Africa. It is an inexpensive mineral, with the greatest expense being the transportation of lime from commercial mines to farmers.
Engineers of the Technology Development Unit (TDAU) of the University of Zambia adapted a hammer mill originally used to mill grain to mill minerals such as lime. It is available from the TDAU at about E 1,860. Alternatively, entrepreneurs wanting to manufacture portable hammer mills, can enter into an agreement with TDAU.
