Horizontal Reciprocating Sand Sieving Machine – Mechanical Project

ABSTRACT –
A sieve is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net. This project focuses in design, fabrication of the mechanical part of machine and the system of the sieve machine. To achieve this project objective, this sieve machine body structure and mechanical system needs to concern some other criteria such as strength, safety and ergonomic design.
INTRODUCTION
Horizontal sieving machine is a machine designed to separate the particle according to their mesh size different levels.in many industry for example the pharmaceutical, it is often desirable to communite particulate matter. A small sieve such as used for sifting flour has very small holes. Depending upon the types of particles to be separated, sieves with different types of holes are used.sieve are also used to separate stones from stand. A metallic plate or sheet, or other similar device, with regularly spaced apertures of uniform sizes,mounted in a suitable frame or holder, for use in separating material according to size. A number used to designate the size of a sieve, usually the approximate number of openings per inch. The normal size of openings usually between cross wires of a testing sieve.

DESIGN CONCEPT

The design of sieve machine must have based on much aspect actually. The design consideration must be done carefully so that the design can be fabricate easily and the system functioning. Then the material used in each design influence the selection thing because absolutely .we need a lightweight material suitable with product size. The design is separated into three phases, firstly choose as many proposed design can be produce then choose 4 designs and try to improve it functionality and the last one is a new design with detail thing including dimension by using Solid Work software.
Beside that the cost to design and fabricate must reasonable mustn’t exceeded the budget given try to reduce waste .
The criteria that must be considered in designing the sieve machine are:
Durability: sieve machine must be durable whenrotate and vibrate. Material : The material that will be used must be suitable to fabricate the Sieve machine and easy to get.
Cost : It depends on material and manufacturing processes. It should reduce the cost to the minimum.

CONCLUSIONS

In this research study, the mild steel failure problems encountered by loads were successfully addressed by applying the Taguchi Method. A Taguchi orthogonal array, the signal-to-noise (S/N) ratio and analysis of variance (AVOVA) were used for the optimization of welding parameters. The optimum levels obtained are A3B3C3. It is found that welding speed has major influence on tensile strength of welded joints
