What is silica?
Silica has the chemical formula SIO2 and it is made from silica mines. This material is composed of silicon and is present in nature in free and silicate form. This material is non-metallic with 25% abundance and it is a hard material that is colorless or dark gray in color. Due to its very high resistance, silica stone has made it one of the most widely used stones in nature, according to that this substance has many uses and properties, you need silicon dioxide to complete your production process in one of the branches of the industry, Therefore, it is sometimes called filter sand silica.
This element is in the form of powder, food and stone, each of which has its own specific uses.
In fact, micronized silica is a type of industrial powder that is used in various industries. This mineral is one of the most widely used materials in industries. Resistance to heat, wear, and detection are among the uses of this non-metallic material in industries.
This product has a lot of diversity. And you should pay attention to this point. They produce and supply this type of silica in a ground and granulated form, which makes it possible for you to prepare according to your needs. Choose any of the sizes of this product. If you are planning to buy silica, you can visit PMD_GRP website and buy while knowing the current price of micronized silica and its different types.
Types of micronized silica mills
As we mentioned, silica stones are prepared for grinding after extraction and determination of their purity. In general, grinding this widely used mineral can be divided into several categories, including the following:
•Jet mill:
This method is usually used to produce food and pharmaceutical powders. In other words, in this method, silica collides with the high-speed energy of air and gas and turns into powder, which is called micronized silica.
•Raymond Mill:
In this method of grinding, milled silicas are used to produce industrial powders. In other words, in this method, which is also known as a roller, a roller is used to pulverize silicas.
•Advanced Raymond mill:
This micronized silica grinding method is often used to produce powders that are used in the form of fine and ultrafine granulation. It should also be noted that this grinding method is generally used to crush and grind stones such as calcium carbonate, iron ore, mica, and copper ore.
•Separator mill:
Separator can actually be considered as one of the newest and most up-to-date grinding devices that are used in the country today. One of the important features of this device is its speed, accuracy and high quality.
•Ball mill:
It is a cylindrical device whose other name is ball mill. Bullets inside this device rotate around an axis at high speed. This work causes any material such as minerals, colored and ceramic materials to be crushed and turned into powder.
Properties of micronized silica:
•High heat resistance
•Improve physical properties
•Improved moisture absorption
•Improved prevention of calcium carbonate formation

More details about micronized silica:
This powder increases mechanical strength and plasticity after mixing with liquids and solids. It also increases thermal resistance, adhesion coefficient, high durability against impact and wear and improves quality. The following can be mentioned from its physical and chemical characteristics when buying micronized silica powder

The price of silica powder
The price of this material is greatly influenced by what type of mesh it is. In Iran, various meshes are produced with the most equipped devices and the highest quality. This process is implemented by large industrial complexes. The price of silicon powder is competitive with foreign samples. The size of the mesh available in our factory is according to the following table:

Micronized: Filling all the tiny pores on the surface of concrete and mortar
Fine grain: Increased adhesion in tile sections
Sugar: Reduction of modulus of elasticity in coarse sand
