The actual distribution of marks at different taxonomy levels (of R, U and A) in the cpiestion paper may vary from above table.
Suggested Student Activities:
Other than the classroom and laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course: Students should conduct following activities in group and prepare reports of about 5 pages for each activity, also collect/record physical evidences for their (students) portfolio which will be useful for their placement interviews:
- Identify the principle by which size reduction is done in Nut cracker and Filing.
- Compare Blake Jaw Crusher and Dodge crusher.
- Prepare list of size reduction equipment used in Cement industry.
- Prepare list of size reduction equipment used in Paint industry.
- List various principles by which solid-solid separation can be done.
- Identify the unit operation used for separation of
- Iron-wood chips
- Calcium Carbonate-water
- Visit nearby industries to study various conveyors.
- Visit nearby construction sites/industry to study working of various mixing equipment

Suggested Micro-Projects
Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project are group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.
The micro-project could be industry application based, internet-based, workshopbased, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry oriented COs.
A suggestive list of micro-projects are given here. Similar micro-projects could be added by the concerned faculty:
- Visit to plant: Visit the nearby industry and prepare report about various mechanical operations.
- Preparation of model: Prepare model of Belt/screw/bucket conveyor
- Preparation of model: Prepare model of plate and frame filter.
- Collection of different samples: Collect solid particle of different sizes and shapes from process industries/Laboratory.
