The physical properties of cashew nut shells were studied as it is necessary in handling, drying, heating, CNSL extraction and other relevant processing operations. The physical properties of the cashew nut shell at moisture content of 10.16 per cent (wb) studied were size, surface area, bulk density, angle of repose, co-efficient of friction and terminal velocity. The cashew nut shells were classified into three sizes i.e. small, medium and large. The percentages of these sizes found in the commercially available sample of shells were 9.74 per cent, 77.46 per cent and 12.80 per cent, respectively. The average values obtained were 2410 mm2, 314 kg/m3 and 4.91 m/s for surface area, bulk density and terminal velocity, respectively. The angle of repose of medium size shells (23.250) was quite close to that of control (23.610) sample of shells. The co-efficient of friction was observed maximum for mild steel surface.

The physical properties of cashew nut shells were studied as it is necessary in handling, drying, heating, CNSL extraction and other relevant processing operations. The physical properties of the cashew nut shell at moisture content of 10.16 per cent (wb) studied were size, surface area, bulk density, angle of repose, co-efficient of friction and terminal velocity. The cashew nut shells were classified into three sizes i.e. small, medium and large. The percentages of these sizes found in the commercially available sample of shells were 9.74 per cent, 77.46 per cent and 12.80 per cent, respectively. The average values obtained were 2410 mm2, 314 kg/m3 and 4.91 m/s for surface area, bulk density and terminal velocity, respectively. The angle of repose of medium size shells (23.250) was quite close to that of control (23.610) sample of shells. The co-efficient of friction was observed maximum for mild steel surface.
