sand maker; A machine for producing artificial sand
Sand is one of the main raw materials in various industries, especially the construction industry. This valuable substance is found in both natural and synthetic forms. Natural sand is formed through natural processes such as erosion of rocks in rivers, beaches and deserts. Due to the increasing demand for sand, its natural resources are rapidly decreasing. For this reason, artificial sand production has been considered in various industries. Artificial sand is produced by crushing larger rocks. In this process, various devices such as stone crushers, mills and salt sanders are used to turn large stones into fine sand grains. In this article, we are going to review the types of sand making machines and their use. Stay with us until the end of the article.
What are sand makers?
Sand makers are machines that convert medium-sized aggregates into finer ones. These devices are usually placed at the last stage of the crushing process and their output is sand with standard sizes. In general, sand makers are divided into three main categories:
Rock crushers: They crush rocks using hammered plates.
Impact crushers: stones hit each other at high speed and are crushed.
Centrifuges: use centrifugal force to crush rocks.
Each of these types of sand makers have different models such as rabbit, pocket and rock and rock sand makers. In the following, we will take a closer look at each of these models.
Types of sand making machines and their use
Each industry needs different sand according to its needs. As a result, a variety of sand making machines have been made to meet these needs. Among the most important types of sand makers, the following can be mentioned:
Rock and Rock sand maker
Rock and Rock sand maker is one of the most advanced and efficient rock crushing devices that works in a different way than other rock crushers. In this device, which is a type of impact crusher, instead of using tools such as hammer or jaw to crush stones, the stones themselves are used as crushing tools. After turning on the device, the stones hit each other at a very high speed inside the sand making chamber and are divided into smaller pieces. These successive collisions cause the rocks to gradually crumble and turn into sand grains. The size of the grains output from this machine is usually between 6 and 30 mm, and its production capacity is between 20 and 30 tons per hour.
One of the unique features of the rock and rock sand maker is the sharp and angular shape of its output grains. This feature is created due to the multiple collisions of stones with each other and makes the produced sand very suitable for certain uses such as concrete production. To increase the efficiency of this process, blades with different angles are installed on the rotor of the device, which causes the stones to collide with each other before hitting the walls of the chamber.
Another interesting feature of Rock and Rock sand maker is not using protective covers (liner) inside its chamber. In this device, the stones themselves protect them from wear by creating a protective layer on the walls.
Rabbit sand maker
Rabbit sand maker is one of the types of impact crushers that is used to crush stones into smaller pieces. In this device, there is a vertical shaft on which several hammers are installed. When the machine is turned on, this shaft starts to rotate and the hammers hit the incoming stones at high speed and crush them.
This shredding process is done by centrifugation; This means that the stones are thrown towards the walls and crushed by centrifugal force. The size of the grains output from this machine is usually between 0 and 6 mm.
One of the unique features of the rabbit sand maker is the presence of three access doors in different parts of the device. These doors allow technicians to easily access the interior of the machine and replace damaged parts. The production capacity of this machine is similar to rock and rock sand maker and is between 25 and 30 tons per hour.
Advantages and disadvantages of rabbit sand maker
benefits | Disadvantages |
Relatively high production capacity | More energy consumption than some other types of sand makers |
The ability to crush all kinds of stones | Limiting the size of stones entering the device (maximum 4 cm) |
Production of fine and powdered particles | |
Ease of access to internal parts for maintenance |
pocket sand maker
Pocket or double-sided sand maker is one of the types of impact crushers, which is used to crush stones into smaller pieces, especially soft and medium stones. Compared to Qubit stone crusher, this device has larger dimensions and higher production capacity. The overall performance of pocket sand maker is very similar to impact crushers. In this device, after entering the crushing chamber, the stones collide with the hammers connected to the rotor at high speed. Then, these stones are thrown towards the two pillars that are located on both sides of the chamber. The presence of two anvils in this device causes the stones to be affected by stronger blows and turn into smaller pieces.
In addition to hammers and anvils, there are other parts inside the pocket sand maker chamber that complete the crushing process by making repeated collisions with the stones. In this way, the stones entering the machine are gradually crushed to the desired size and come out of the machine in the form of sand.
Choosing the best type of sand maker; Which one is right for you?
Considering that there are different types of sand makers in the market and each one has its own features and uses, choosing the best sand maker depends on your needs. It is better to contact our experts at Aftab Machine before buying a sand maker so that you can get a suitable device for your needs.
For comparison, we can say:
Rock and Rock sand maker is widely used in concrete and asphalt production industries due to its high ability to crush very hard stones such as barite, dolomite and granite. Due to the sharp and angular shape of the grains, the sand produced by this machine has very good adhesion with cement and increases the strength of concrete.
Pocket or double-sided sand maker with high production capacity is mostly used for crushing large aggregates and materials extracted from mountains such as gypsum, lime and dolomite.
Rabbit sand maker is mostly used in sand mines due to its ability to produce broken sand with uniform granularity. The sand produced by this machine is very suitable for construction and road construction purposes.
summary
In this article, we got acquainted with different types of rock and rock, pocket and rabbit sand makers and described the uses of each in different industries. In the processes of crushing hard stones and producing high-quality sand for concrete and asphalt, or producing crushed sand for construction purposes, each type of sand maker plays its role.
The most common types of sand maker include rock and rock, pocket and rabbit sand maker.
Their main difference is in the way of crushing the stones. Rock and Rock uses rocks hitting each other, an envelope uses rocks hitting anvils, and a rabbit uses hammers hitting rocks.
Sand makers are used in various industries such as construction (production of concrete and asphalt), mines (crushing of minerals), cement production and mining industries.
