2. • Sand and gravelare essential materials
for construction,mining and agriculture.
• Sieving these materialscanbe time-
consuming and labor-intensive.
• Rotary sand gravelsieving machine is
adevice that cando this
work efficiently.
WHY?
3. • Itusesaperforated meshrolled in cylindrical
shape.
• Ithas adrive mechanism, a
small feeding hopper and arotating sieve
drum.
• Itseparatessand and gravelmixture by size asthe
drum rotates.
• Itcanbreakup lumps and agglomeratedmaterial.
HOW IT WORKS
4. • Themachine sievesfasterand more efficiently
than manual sieving.
• Themachine reduces time and labor costs for
sieving.
• Sieveslargequantity of material in ashorter period
of time.
• Themachine canbe used for different purposes
and industries.
WHAT IT DOES
5. POTENTIAL AREAS OF
IMPROVEMENT
• Incorporate sensorsand automation to enhance
sieving performance.
• Developamobile version of machine
for portability.
• Expand the range of materialsthe machine can
sieve.
6. • Learnedabout machine
componentsand specifications.
• Practiced welding,cutting, grinding
and drilling skills.
• Developed projectmanagement
skills,suchas time management,
budgeting and teamwork.
• Overall, enjoyed the projectasa
learning experience.
THINGS I LEARNED
