The document describes the design, fabrication, and evaluation of a multi-purpose siever. It discusses sieving processes and the need for a machine that can sieve different materials like sand, vermicast, and manure. The proposed siever aims to simplify and speed up sieving. It will be designed, built, and tested to determine its efficiency, fineness, power consumption, input/output capacities, and ability to recover products. Related studies on multi-purpose sieving machines are also reviewed to support the project.

EVALUATION OF A MULTI-
PURPOSE SIEVER

2. Sieving is a physical mechanism of particle
removal, where a particle is denied access
through a pore or passageway that is smaller
than the particle itself (Sterilization and
Sterility Assurance for Pharmaceuticals, 2013).

3. Sand, and organic materials such as,
vermicast and manure are the main factors
used to evaluate how well sieving machines
perform, according to studies (Meshram et al.,
2022; Hasan and Souruv, 2021; Kabudake et al.,
2020).

4. Sieve analysis determines the particle size distribution
of a given soil sample and hence helps in easy
identification of a soil's mechanical properties. These
mechanical properties determine whether a given soil
can support the proposed engineering structure. It also
helps determine what modifications can be applied to
the soil and the best way to achieve maximum soil
strength (Gradation Test, 2007).
RATIONALE

5. The problems of sieve analysis are that it requires
much time and reagents. The sieves may suffer
damage, they are difficult to clean and dry, it is
difficult to filter suspensions through sieves of
smaller mesh, fat globules may plug the mesh, and
processing the results requires much time and labor
(Lengyel S. et al., 1991).
RATIONALE

6. These problems can be alleviated using exchangeable
screen. This project has a home in this vital part of the
world. The machine is designed to be simple, and that it
can perform at a high rate of output. Now the goal is to
design, fabricate, and evaluate a simple, cost-effective,
and easy operation multi-purpose siever machine.

9. Sieving plays an important role in the daily operations of a
wide range of businesses in the field of technical education. The
systematic approach is the method of choice when building a
work device within specific parameters. Sieving is a simple
method for sorting particles according to their size. (Becker, M. Y.,
&Sewell, P., 2004; Berg, Seymour, & Goel, R., 2013; Bjeladinovic,
Marjanovic, & Babarogic, 2020; Chandra, 2015).

10. The use of sieving for analysis of particle sizes has been
around for hundreds of years. The process is thought to have
originated in ancient Egypt to measure grain harvests (and still is
used for that purpose today). Throughout the centuries, the
procedure has been applied to many different applications
(Humboldt Mfg. Co., 2023).

11. Vibrational sieving is a sieving method used to assess the
sizes of granular materials such as gravel. During this procedure,
the particles or objects are subjected to three-dimensional
shaking movements (usually a circular motion superimposed
with a vertical or horizontal motion) over a sieve
(Corrosionpedeia, 2023).

13. Vermicasting, also called vermicomposting, is the processing
of organic wastes through earthworms. It is a natural, odourless,
aerobic process, much different from traditional composting.
Earthworms ingest waste then excrete casts — dark, odourless,
nutrient- and organically rich, soil mud granules that make an
excellent soil conditioner.

Adhapure et al., (2021) presents the
concept of Design and Fabrication of
Multi-purpose Sieving Machine mainly
carried out for production-based
industries. They developed a conceptual
model of a machine capable of
performing different operations
simultaneously and easily. In this machine,
the main shaft is driven using a motor to
which the slider-crank mechanism is
directly attached; the slider-crank
mechanism is used for sawing operation.

construction sights. Sand can be sieved
with this machine as sand is both known
as powder and granular according to the
diameter of sand particle. This device is
normally designed for the building
construction labors of Bangladesh with
the construction theme of Screw
Conveyor. The materials of this device
have been selected under the
consideration of monetary value.

sand is sieved by old hand-operated

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. Depending
on their size the individual particles either
pass through the sieve mesh or retained
on the sieve surface (Chavan et al., 2022).
