4. Conclusions
(1) Production of 35 mm briquettes made from groundnut shell using 35 mm die and
punch unit was satisfactory. Energy requirement per tonne of briquettes was more
(67 kWh) compared to 60 mm briquettes (56 kWh). The reason for increasing the power
requirement was due to reduction in the production rate of briquettes and due to over
rating of electric motor as modification was carried out on 60-mm-dia briquetting
plant.
