ABSRACT
The fabrication of a set of sieves and shaker was carried out in paliton workshop, Enugu. After a thorough analysis on the suitable materials to be used in fabrication, galvanized steel was chosen due to its advantages over materials of fabrication. The fabrication was carried out in order to analyze the sizes of particles. The component parts of the sets of sieve and their dimensions are as follows:
Height of sieve 5.5cm
Number of sieves 7
Diameter of sieve 13.5cm
Shape of sieve circular
Height of sieve set 44cm
In fabricating this set of sieves, some factors were taken into consideration and they are:
The capacity of the sieve.
The type of mixture that can be filtered in it.
The types of properties and composition of the mixture.
The type of material to be used for fabrication of the sieve and shaker.
The mechanism of the filtration process and also,
The cost, which is the determinant, factor in fabrication of any equipment.
These factors help greatly in the fulfillment of the objective of this project study. And after fabrication the projects were tested and seem to be working very efficiently with a reasonable separation of particle and cut diameter.
Using the above dimensions, the following fabrication procedures were undertaken, layout, cutting, drilling, welding, filling sand papering, washing and painting, drying assembling.
Finally, the set of sieves and shaker were subjected to the process of washing, painting and drying.
