2. INTRODUCTION
• Sand Screening Machine is also called Sand Sieving Machine.
• Sand is one of the most important thing in industrial world. Now a days the industry
need the sand that are already been process known as sand product. As we know the
sand mixture with variety other component such as dirt and metal.
• As we know the way sand is been collected still used the conversional way such as
sieving using hand or machine. And human energy is needed to run the process. So to
make the process more efficient new technology is needed to help increase the
productivity so the human power can be reduce and also can cut the cost of the
process

3. INTRODUCTION
• Sand or any mixture usually comes in different size and grid since some product
required different size of sand or mixture that why this machine been design to sieve
the sand or sub stand into different size depend on requirement needed.
• The problem of size of sand in the market available. Need to spend more money if
we want the sand in specific size or category it will increase the budget and time to
wait the supplier preparing the goods.
MED-VAST TC 3

4. INTRODUCTION
• Now days people always prefer the most suitable way to cut their cost and time.
Example in a construction where they have to finish the work before the due date.
This might be a problem.
• However, sometime in big company there are high tech machine that can do this
work sieving any sub stand or mixture. But sometime in construction required a
special sieve machine that are comfortable and easy to use.

5. HISTORY OF SIEVE MACHINE
• The figure shows the process been use by people before us the ancestor way to sieve
the sand
• And collect the sand they wanted. This process sieve the sand into it size depending
on the size of the net been used. This smooth sand or the product usually use as main
material in construction to build building or house.
• Smooth sand is required to achieve better quality product example in making sand
casting or making any product based on sand.

7. HISTORY OF SIEVE MACHINE
• The figure shows modified sieving method. It use handle to rotate and make the
process sieving more efficient , mainly use in small manufactured process such as in
lab.
• Now a days it has been upgrade using motor to replace the human power. Since this
machine is important in our daily life it has been upgrade one bye one. And been
marked almost all over the world.

9. HISTORY OF SIEVE MACHINE
• The figure shows modern sieve machine. Using the electrical motor
it vibrate as it mechanism It has many different size layer so the sand
comes in variety size. We just need to chose the size. The magnet
also is installed in this machine to remove the any metal substance.
Because metal can cause corrosion.

• Important constituent of concrete is natural sand which is
expensive and scarce
• Crushing natural stone to desired size-easiest and cheapest way
• Screening is the process of removing larger sand particles and
impurities
• By screening, strength and quality of concrete increases
MED-VAST TC 12

13. CONSTRUCTION AND WORKING
• Sand to be screened filled in the drum using hopper
• Drum is mounted on a shaft driven by electric motor
• When the drum rotates then sand particles move randomly and
passes through the net.
• Here the process is used for screening sand size of 7.5 micron to
4.5mm
• The drum is inclined for good movement of the sand by gravity
process

A THREE STACK MECHANICAL SIEVE
SHAKER FOR DETERMINING AGGREGATES
• The size distribution of dry soil aggregates provides
information on soil’s physical structure
• Aggregates size distribution of soil is usually determined by
either wet sieving or dry sieving.
• Determining aggregates size distribution of a soil by hand is a
very laborious process in order to simplify the process
mechanical shakers are developed.

25. CONSTRUCTION
• There is rigid immobile load bearing frame(consist of base
frame front support vertical support U support and top bar)
• Three pins rigidly attached to base frame which support a big
ring
• This ring has series of evenly spaced cam like elevations
• Energy is transferred from 14 HP motor to the driven shaft by a
linked belt and pulley system
• Each soil sieving stack consist of 7 sieve ranging from sieve no.

26. PRINCIPLE OF OPERATION
• Soil to be sieved Is places in the top bowl
• Energy is transferred to the shaft with the soil sieve bases assembly
• The reciprocating vertical motion provides the sieving action
• If the system is shaken long enough eventually only soil particles
which are larger than the mesh size will be left in each sieve.
Result and discussion
• During the testing the constructed three stack mechanical shaker
produce a smooth oscillating
• Removal and placement of sieves was easier using the new machine

29. EXPERIMENT 2
• Examining permeability and capillary water in earth material
MED-VAST TC 29

30. • The speed with which the water moves through a material is
termed permeability
• Materials used :
1. funnel
2. Stop watch
3. Beaker
• The amount of water trapped between the particles as capillary
water or soil water can be determined
