Fabrication for a Set of Sieves and Saker

Fabrication for a Set of Sieves and Saker

ABSTRACT

The fabrication of a set of sieves and shakers was carried out in the Paliton workshop, Enugu. After a thorough analysis of 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 to analyze the sizes of particles. The 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

The shape of the 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 the fabrication of any equipment.

These factors help greatly in the fulfilment 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 sandpapering, washing and painting, drying assembling.

Finally, the set of sieves and shakers were subjected to the process of washing, painting and drying.

CHAPTER ONE

1.0 INTRODUCTION

Generally, all engineering aspects involve fabrication more especially for chemical plants or equipment, which are used for several processes. This fabrication is carried out to achieve and put to practice chemical processes with the help of some components for equipment used for the fabrication procedures enables engineers to deal with operations for separating the component of a mixture, which is automatically based on particle size analysis of materials from one particular sieve to another.

Chemical engineering mostly deals with the fabrication of sieve among other fabrications to fulfil the theory of separation technique. In separation processes especially particle size analysis is where sieving techniques are available.

During the operation of particle size analysis, many types of screens can be involved, which include Grizzy screens, Revolving screens, mechanical shaking screens, vibrating screens, electrically vibrated screens, oscillating screens, Reciprocating screens and Gyratory screens.

As this project involves the fabrication of a set of sieves, it, therefore, requires a good layout and easy separation of oversize and undersize in the contacting sieve unit.

Moreover, in the fabrication of a set of sieves, we have to bear certain qualities in mind which the set of sieves will have to portray such as determination of the size and shape of the equipment, which contributes to the efficiency of the equipment. Among the above aim, the set of sieves should be considered in terms of costing and also availability and portability of the set of sieves should be considered.

Above all, the set of the sieve is fabricated in such a way that the particle of larger size than that of the sieve will be retained on the sieve while the particle of lower size will pass through the sieve and be collected on and another sieve as undersize, which is also separated by that sieve.
