How is it produced?
Sand is one of the most widely used materials in the construction industry, road construction, building construction, etc., which plays an important role in various sectors. has our life As a result of crushing or abrasion of stones, small stones are created which are called sand. In nature, stones are turned into small particles due to exposure to wind, rain or strong storms, and these particles with dimensions smaller than 2 mm are called sand, but there is another way to produce sand, and that is the production of this The products are in the factory.
How to produce sand
Sand: stones with dimensions between 4 and 60 mm are called sand, which can be natural or be formed artificially. According to the way sand is formed, these stones can be made of any mineral and stone, and depending on the place of formation, they can be seen in round, angular, etc.
< p>Sand: Small stones that have dimensions below 4 mm are called sand and can be called It is a kind of shrunken form of sand.انی Sands
Depending on the type of formation, sand is placed in two categories, natural and artificial. Sand is formed naturally in seas and deserts. These pebbles are formed in the deserts due to the wind and in the sea due to the impact of the waves on the rocks.
ی Natural sand and sand
Natural sand is produced by nature and humans are not involved in its production. Among the types of natural sand, we can mention river sand and wind sand. There is dirt in wind sands, which are washed to remove impurities before entering the market.
ان Sen artificial sand and sand
Sand production by synthetic method
To produce sand in factories, first the stones extracted from the mines are directed to the factory. Inside the factory, the stone is washed or its impurities are removed by the devices installed in the production line. Mineral stones are crushed with the help of stone crushers and their dimensions are reduced enough to be ready for use in construction and construction industries. Depending on their location, stone crushers are classified into three categories: primary stone crusher, secondary stone crusher and tertiary stone crusher, each of which has the ability to crush stones to certain dimensions.
انی The equipment used in sand production lines
⚫️ Jaw Crusher
The first device that is placed in the sand production lines is the jaw crusher. This stone crusher has the ability to crush all kinds of mineral stones and reduce their dimensions to a significant extent. The operation of shrinking the stones in this device is done by moving the movable jaw towards the fixed jaw.
⚫️ Cobate Breaker
After the stones exit from the jaw crusher, it is necessary to perform another operation on them to reduce the output size. For this, the stones enter a device called a qubit, which uses a hammer and a hammer to shrink the stones. Upon entering the qubit, the stones collided with a rotor covered with a hammer, and with the help of the hammer particles, their size was reduced and thrown towards the anvil. There are parts installed inside the anvil that reduce their size when they hit the stone.
⚫️ Models
In addition to the stone crushers installed in the first and second stages, in sand production factories, they use stone crushers called sand makers. which reduce the size of stones to a great extent and make them ready for use in other industries. Sand makers are divided into pocket sand makers, rabbit sand makers, rock and rock sand makers, etc. depending on the internal structure and how they work.
Salt
To increase the quality of the produced sand, they use a salt sand machine to remove the soil placed on the stones.
⚫️ Drag
After leaving the salt sand, the stones are directed to the dryer to remove their moisture.
⚫️ Calling
Inside manufacturing factories, conveyor belts are used to move products. This work will increase the speed of the production line and reduce financial and life injuries, and on the other hand, at the end of the day, the amount of the product produced can be estimated.
