Cracked palm nut mixture was classified by sieve analysis, and the fractions retained on the 10 and 15 mm sieves were used for the evaluation of the machine performance. Operating the separator at 55 rpm yielded kernel recovery and kernel purity of 96% and 42.86%, respectively, for the mixture retained on 10 mm sieves.

2.2 Size of Palm Kernel Nut, Shell and Kernel. Measurement of sizes of the nuts was taken from Five (5) samples of 500 dura-nuts. Fifty nuts were measured in each sample, the average size of diameter of the palm kernel nuts ranged from. 11.00 to 29.60 mm and the size of shell thickness ranged from 2.20 to 8.60 mm.

The shell recovery, shell purity, separation efficiency and throughput capacity were 80.16, 94.17, 73.66 % and 313 kg/h, respectively. The results showed that the separation technique is viable for effective separation of the dry palm kernel and shell mixture.

Palm kernel and shell separators are of two types based on the wet and the dry methods. The wet method uses clay slurry, brine solution or a hydrocyclone, and generally exploits the differences in the densities of the kernel and the shell as the physical basis for separation (Hartley, 1977; Henderson & Perry, 1980; Opeke, 1997).
