Cereal crops are the major dietary energy supplier in Africa especially in Nigeria. In most Africa countries, cereals supply estimated 80% of the energy requirements. Major categories of cereals produced in Nigeria include rice, sorghum, maize, etc. It is mostly grown in the savannah ecological zone of the country. Processing and storage of the products are the major factors that limit its commercialization in Nigeria. However, crushing of the products to smaller sizes for storage can help for its easy package and preservation, thus this research work. This research work is aimed at designing of cereal crops crushing machine. The machine consists mainly of feed hopper, electric motor, shaft, bearing, V-belt, pulley, etc. Detail design was carried out to know the value of required parameters and components for operation. The outcome of the results obtained show that torque of 15.05 Nm, shaft diameter of 20mm, crushing force and power of 650N, and 2hp were required for efficient operation of the machine.
