Artificial sand making process pdf in Karnataka
Artificial sand is a type of sand that is made from crushed stone, slag, or other materials. It is often used in construction because it is more durable and consistent than natural sand.
In Karnataka, there are a number of artificial sand making plants. The process used to make artificial sand in Karnataka is similar to the process used in other parts of the world.
The first step in the process is to crush the raw material. This can be done using a variety of methods, including jaw crusher, cone crusher, and impact crusher.
Once the raw material is crushed, it is washed to remove impurities. The washed material is then dried.
The dried material is then fed into a sand making machine. The sand making machine uses a rotating screen to separate the sand from the larger particles.
The sand is then collected and stored.
The following are the steps involved in the artificial sand making process in Karnataka:
- Crushing
The first step in the process is to crush the raw material. This can be done using a variety of methods, including jaw crushers, cone crushers, and impact crushers.
Jaw crushers are the most common type of crusher used in Karnataka. They are simple to operate and maintain, and they are relatively inexpensive.
Cone crushers are more efficient than jaw crushers, but they are also more expensive. They are often used to crush materials that are difficult to crush, such as slag.
Impact crushers are the most efficient type of crusher, but they are also the most expensive. They are often used to crush materials that are very hard, such as granite.
- Washing
Once the raw material is crushed, it is washed to remove impurities. This is done by passing the crushed material through a water bath. The impurities float to the surface and are skimmed off.
The washing process helps to improve the quality of the sand by removing dirt, clay, and other impurities.
- Drying
The washed material is then dried. This can be done using a variety of methods, including natural drying, mechanical drying, and thermal drying.
Natural drying is the most common method used in Karnataka. The washed material is simply spread out in the sun to dry.
Mechanical drying is faster than natural drying, but it is also more expensive. The washed material is passed through a hot air dryer to dry it.
Thermal drying is the fastest method of drying, but it is also the most expensive. The washed material is heated to a high temperature to dry it.
- Sand making
The dried material is then fed into a sand making machine. The sand making machine uses a rotating screen to separate the sand from the larger particles.
The sand is then collected and stored.
The sand making machine is the heart of the artificial sand making process. It is responsible for producing the finished sand product.
There are a variety of sand making machines available, each with its own advantages and disadvantages. The most common type of sand making machine used in Karnataka is a vertical shaft impact crusher.
Vertical shaft impact crushers are efficient and produce high-quality sand. They are also relatively inexpensive.
- Collection and storage
The finished sand is then collected and stored. The sand is usually stored in a silo or bunker.
The sand is then ready to be used in construction.
Artificial sand is a versatile material that can be used in a variety of construction applications. It is more durable and consistent than natural sand, and it is also more environmentally friendly.
