The document describes a project to design and construct a horizontal sieving machine. It includes an introduction describing sieving and its uses. It outlines the objectives, materials used, tools used in the methodology. It describes the working mechanism, provides photos from construction, and concludes that the project provided learning and was essential for the pharmacy department. It encountered some problems during construction but overall achieved learning objectives and completing the project.

1. Project On Horizontal Sieving Machine
Presented by
 Niraj Bartaula (06)
 Ramendra Bastola (07)
 Santosh Bhatta (08)
 Dinesh Bhattarai (09)
 Ritu Bhusal (10)

2. Acknowledgement
We would like to express our gratitude to the project in-
charge and coordinator Mr. Badri K.C Sir for his continuous
support and help. Similarly, we are thankful to mechanical
work shop teacher’s and all our colleague’s who helped us to
make this project accomplished.

3. Introduction
 Horizontal Sieving machine is a machine designed to separate the
particle according to their mesh size at different levels.
 In many industry for example the pharmaceutical, it is often
desirable to comminute particulate matter i.e. to reduce the
particular size of a given material.
 Sieving is a simple technique for separating particles of different
sizes. 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. Sieves are also used to separate
stones from sand.

4.  Sieve: A metallic plate or sheet, or other similar device, with
regularly spaced apertures of uniform size, mounted in a suitable
frame or holder, for use in separating material according to size.
 Sieve number: A number used to designate the size of a sieve,
usually the approximate number of openings per inch.
 sieve size: The nominal size of openings, usually between cross
wires of a testing sieve.

7. Objective
 To design and construct economical and easy handling sieving machine for obtaining
uniform particle size of raw materials.
 To understand the basic principal of size separation.
 To know about the equipment and devices used in pharmacy lab.
 To develop interpersonal skills and to be familiar with the tools and process used in
mechanical workshop.

8. Material Used
 Wood and ply
 Iron sheet
 Rivets
 Sliding channel
 Nails
 Fevicol
 Rod and Angle bar

9. Tools and machines used
 Files
 Snip
 Plier
 Mallet And Hammer
 Center punch
 Chisel
 Drilling machine

10. Methodology Used
 Marking
 Cutting
 Filing
 Drilling
 Folding
 Riveting
 Welding

11. Working Mechanism
Steps:-
 Input from topmost sieve.
 The sieves are then vibrated and moved horizontally.
 Particles passing from lowest sieve are collected in receiver.

12. Cost Estimation
S.No Equipment Quantity Amount
1 Wood and Ply
2 Barring
3 Slider
4 Fevicol and Hot Glue
5 Sieve
6 Iron nail,Screw,Nuts and Bolt
7 Transpotation Carge and Others
8 Total

13. Scope And Limitation
 Wide application in the pharmaceuticals industries, lab.
 Separate compartment of different mesh size.
 It can be operated manually.
 Linear motion with vibration(due to striking) makes it more effective.
 The machine is easy to operate and anyone with a little knowledge also can
operate it.

14. Problem Encountered
 Due to the breakage of sliding channel, it has to be changed.
 Several parts made up of ply was replaced. Hence, it consumed more time and
cost.
 Less skills on Welding.
 Barring was jammed while grinding.
 The shaft didn’t get fitted in the flywheel.
 Coupling didn’t hold bearing properly.

15. Our Achivements
 Learned to handle mechanical tools and work in the workshop.
 Developed various interpersonal skills during the work.
 Learned to work in a team and help each other.
 Learned about various tools used in Pharmacy lab.

16. Conclusion
We felt great doing the project and are very happy after the
completion of the project. It is a matter of immense pleasure to be
able to contribute something that is essential to our own Pharmacy
department.
