Ball mil or pellet mill
What is Ball mill?
A mill is a mechanical device with which solids and hard materials are converted into smaller pieces by cutting, crushing or pulverizing. In fact, the most important principle in the work of milling machines is to break solids and hard materials into smaller parts under the influence of mechanical force. At first, the mills worked with human muscle force, and soon after, humans were able to use animal force, wind and water for this purpose, but today there are many types of advanced mills that play a very important role in the industry.

If you are familiar with industrial mills, it is most likely that ball mill or pellet mills have been eaten into your meat. But the question is, what exactly is Ball mill and what does he do?
In a general and simple definition of ball mill, it can be said that ball mill is an industrial mill whose size and dimensions of output load are in nanoscale. ball mill or pellet mill, as the name implies, performs the mill’s work using bullets of different sizes that are located inside the body of the machine.
ball millcan be considered a kind of grinding machine. This functional device is composed of an empty nested cylinder that revolves around the horizontal axis. (The axis of the shell may also have a slight angle to the horizon. ) The inside of this cylinder is filled with steel or ceramic pellets, and when the material enters the pellet mill, they become as desired as the result of the threshing of the pellets placed inside the ball mill.
ball mill is used in various industries such as food, pharmaceutical, recycling or ceramic tile and its application is widespread in today’s world of industry.l
How does Ball mill work?
As to how a ball mill or granulator works, we can say that ball mill works on the principle of impact and abrasion. Because when the device begins to rotate around its axis, bullets fall on top of the material and due to the continuous and continuous impacts of the granules on the material, micronization is performed.
As mentioned earlier, a ball milll usually consists of a cylindrical or cone-shaped steel body filled with several granules. The material of the granules can vary depending on the application of the ball mill and the materials it grinds.
First, the body of the Ball mil device begins to rotate around a horizontal axis. With the beginning of the rotation of the mill body, friction between the mill wall and the granules inside it leads the granules upwards in the direction of rotation. After that, the pellets will quickly roll down and their collision with the materials in the mill will crush them. This is repeated over and over again, to the point that the materials are milled to the right sizes.
The conical ball mill hull consists of two cones and one part of the cylinders. The conical design of the ball mill hull allows for a significant increase in efficiency. Why and how? The speed of the environment along the conical drum decreases from the cylindrical part to the output part. The spiral angle of the granules is also slightly reduced, resulting in a decrease in the kinetic energy of the material on the edge of the exit. Placing larger pellets in the deeper and cylindrical parts of the housing reduces the size of the balls in the direction of the discharge outlet and increases the efficiency of the device.
Ball mill Bullets
ball mill bullets can be considered as the main part of the ball mill machine. ball mill a bullets are known as granulate
And a very large part of what The ball mill machine does is responsible for these bullets.
The material of ball milller pellets can vary depending on the application of the machine and is made of various materials such as steel, stainless steel, ceramics or rubber. Of course, in a limited number of cases, crushed stone bullets are also used due to lower prices and more cost-effectiveness.
Ball mill Applications
As can be guessed, ball milll’s application in industries and mines is vast and numerous applications can be counted for this device.
In general, it can be said that ball mill is used for milling or mixing materials, and the output materials are used in various processes such as mineral extraction, paints, pyrotechnics and ceramics.
Pellet mills are used to mill minerals such as coal and pigments. Feldspar used in the pottery industry is also prepared and prepared using ball milll.
ball mill also works in the pharmaceutical and health industries. Small or medium-sized pellet mills are used for the final milling of drugs or for grinding suspensions.
The pellet mill is also widely used in the food industry. In the process of producing products such as quotes, gum or smarts ball mill machine plays an effective role.
Ball mill in Industries and Mines
As mentioned earlier, pellet mill is a type of mill that is chosen for milling and mixing materials for use in mineral processing, paints, pyrotechnics, ceramics and some laser welds. used. Ball mills work on the principle of impact and abrasion, and in fact, by tapping, they reduce the size of the bodies inside the ball mil, and this process occurs with the help of balls being thrown inside the ball mil.
The pellet mill environment is usually filled with steel pellets that grind materials by rotating the mill to be converted into fine powder. The length of the cylindrical body of ball mills is usually 1 to 1.5 times their diameter. This shell is coated with abrasion resistant materials such as manganese steel or rubber to prevent wear and extend the lifespan of the machine.
In general, pellet mills are an important tool in many industries for milling and mixing materials and play an important role in the efficient and cost-effective processing of various materials.
ball mill in industries
Powdering minerals is one of the most important applications of ball mill . Powders of materials such as copper, lead, zinc, iron, silicate and a large number of industrial minerals are obtained using ball mill . ball mills used for this purpose usually have steel pellets and resistant bodies. Because the contact of the body and pellets with minerals requires a high level of resistance.
In the mining industry, pellet mills are used for milling ores and other materials in fine powder form. It is then processed to extract valuable minerals or metals. Pellet mills can also be used for secondary milling of materials after crushing.
In the chemical industry, pellet mills are used to mix chemicals and reduce particle size.
ball mill in the food industry:
ball mill machine is used to grind materials in the preparation and production of many foods such as chocolates, oily creams or breakfast chocolates.
ball mill in pharmaceutical industry:
The chemicals used in the preparation of many drugs will be milled using ball mill machine and ready for use in pharmacy.
ball mill in ceramic tile industry:
ball mill plays an important role in the production process of ceramic tiles. The raw materials of these industries must first be micronized using ball mill and the sauce should be made from the outlet materials of ball mill slurry.
ball mill in recycling industries:
ball mill is also a significant and important application in recycling plants. Preparation of an integrated powder of recycled materials is one of the most important applications of pellet mills.
ball mill in ceramic tile industry
There are several ceramic tile manufacturing plants in Iran and ball mill plays a very important role in the ceramic tile industry. This has made the pellet mill or ball mill a very important role in domestic production.
As mentioned above, one of ball mill’s most important and influential uses is in the ceramic tile industry. Iran has one of the largest ceramic tile products in the world and its rank among the countries producing ceramic tiles is 3. The daily growth of these industries has made v devices more important and their role more vital.
The raw materials of tile, ceramic and porcelain industries must be milled using ball mill machine and converted into particles of nanoscale size. After that, slurry is prepared using the produced particles and other steps will be applied according to the type of tile or ceramic. As you can see, ball mill is one of the main and most important parts of the ceramic tile industry.
Due to the abrasion and erosion properties of the raw materials of the ceramic tile industry, it is very important that the ball mill body is made of abrasion and resistant materials that are not reactive to these materials or use ball mill liner.
Ball mill Types
There are many criteria by which ball mill types can be categorized and distinguished from each other. From axis direction to how to enter and exit materials. In this part of the article, we will examine different types of ball mill with different criteria.
Based on axis orientation:
1-Horizontal ball mill : This type of pellet mill is the best-selling and most widely used bullet mill. Horizontal ball mill is longer and smaller in diameter than vertical ball millls. A large number of horizontal mills have timers, which will allow automatic shutdown of the device after the micronization process is finished.
2-Vertical ball mill : Vertical ball mills are more specific than horizontal ball millls and are usually produced only in limited cases according to the customer’s personalized order. The capacity and capacity of vertical ball mills are less due to their smaller dimensions.
Based on loading capacity:
1-ball mill Industrial: This model of is produced for use in manufacturing plants, industry and mining and can grind a large number of materials at the same time. The capacity and loading capacity of this type of ball milll is high.
2- Mobile ball millls (no more accurate translations) are vertical ball mills that are used in laboratories. Bullets and small compartments are prominent features of ball mill Mobiles. The processing capacity of this type of ball mill is much less than industrial ball millls due to its special application.
Based on how materials are imported and exited
1-ball mill Continuous(Continuous): In Continuous ball mills, materials are simply inserted into the machine from the inlet chamber and after finishing the milling process automatically and automatically, the milled materials are removed from the machine. The performance of this type of ball mill increases the efficiency of the micronization process and causes the trouble of discharging the device to disappear.
2-Ballmil dis Continuous (discontinuous): In dis Continuous or discontinuous ball mills, unlike ball mill Continuous which discharges the output load automatically, after finishing the mill operation, the machine must be turned off and the output load discharged.
Continuous Ball Mill
As mentioned in the previous section of the article, Continuous Ball Mill C or Continuous is a special type of ball mill that, unlike Ballmil dis Continuous , performs the load discharge automatically. Continuous ball millls have more fans among industry owners because of the fewer problems associated with unloading the outlet load. But Ball mill Cantinos’ advantages over Dis Cantinos do not end there. Here are some of ball mill Continuous benefits.
High quantity and quality: The materials imported into ball mill Cantinos are automatically removed from the machine after they have entered the machine and the milling process is finished. This reduces the likelihood of wasting materials or milling more or less.
Reduce the space required for machinery
Fully automatic micronized process
Reduce production costs
Energy saving

SAG mill
SAG mill or semi-automatic mill is recognized as the primary grinding tool. This functional mill is located just before ball mill . When the materials are extracted from the mines, we first grind them using a sagmill to pieces with dimensions of 13 to 16 cm. These parts are inserted into the ball mill machine and are removed from ball mill with a powder-shaped structure. That’s why we consider SAG millsas the primary mill and ball mill as a secondary mill.
In general, unlike ball mill , which converts small pieces into powder, Sagmill plays a role in converting relatively large parts into smaller pieces. Sagmill has a high diameter and shorter length compared to other mills. The application of this device can be found in gold, copper, platinum, silver mines as well as lead, zinc and nickel mines. One of the most important applications of semi-self-breaker mill is separation of precious metals such as gold from coal.
One of the most important advantages of Sagmill machine is that it is used to grind clay and sticky materials that other types of mills are unable to grind.

First, we will compare SAG mill and ball mill. SAG mill is a kind of primary milling tool and is placed before ball mill. In this way, the output load of the SAG mill device is usually used as the input load of the ball mill machine. We use ball milll to grind minerals in powder-like structures, while SAG mill merely reduces the size of larger parts to smaller sizes. Another difference between these two devices is their application. The powder-shaped structure that ball millgives to materials makes it possible in industries such as cement, gypsum, etc. to use. While SAG mill is commonly used in mines and for the separation of precious stones and metals from coal. The number of ball mill bullets, as mentioned earlier, is almost twice as many as the number of Seamill bullets.
ball Mill Liner
Maybe the name of the Ball mill liner has already reached your flesh, but what exactly is the Ball mill liner? What materials is made and what exactly is the reason for using it?
The inner body of ballmil machine always has contact with various materials. Substances with different and possibly traumatic properties. This causes wear, corrosion, rust and reactivity of ball mill body to be recognized as a major problem for industrialists and ignoring it causes great damages. This damage becomes more pronounced when the materials that Ball mill grinds are allergic to metal pollution.
Ball mill liner is designed for exactly this purpose. The pellet mill liner is located on the inner surface of the Ball mill chamber and protects the internal body of the device against impact and damage caused by friction between the body and bullets or the body and materials inside the mill. Exactly what ball mill liner is from or how it is designed varies depending on the application. For example, the ball mill liner that is supposed to deal with minerals and protect the body against them will be different from the ball mill liner that comes into contact with chemicals.
The use of ball mill liner also increases kinetic energy and makes milling better and more effective. The damage to Ball mill and the damage caused will also be significantly reduced. In sum, it can be said that the use of ball mill liner increases production and reduces the overuse of metal.l
ball mill lining
Ball mill liners have different types and in order to achieve the best results and efficiency of ball mill lining, according to the application of ball mill machine, liner should be designed and produced in accordance with the requirements and conditions of the device. Different types of Ball mill liner have different installation shapes.
If our criteria for classification of ball milll liners are materials, it can be stated that the pellet mill liner is usually made of materials including manganese steel, alloy steel, rubber, ceramic and magnet. Rubber liners are one of the most popular and functional types of liners, which are much easier to install and replace due to their light mass than other ball millls.
In general, the main materials used in ball milll lining are alloy steel and rubber. Alloy steel is highly resistant to impact and also has a shelf life of about twice as much as high manganese steel due to its special chemical and physical properties.
The rubber liner has a high wear resistance and the elasticity of the rubber makes this liner very resistant to tearing and abrasion. One of the most important advantages of rubber liner is that noise and noise pollution of ball mill device is significantly reduced.

FREQUENTLY ASKED QUESTIONS ABOUT BALL MILL
In general, it can be said that pellet mills are used to grind or grind materials in a completely fine and powdery form and are used in mineral processing or pharmaceutical industries.
Ball mill’s work is based on the principle of impact and abrasion. The rotation of the ball mill chamber around a fixed axis causes the bullets to go above the shell and from there to fall on the material. This will cause micronization of the materials inside the mill.
In terms of the way of entering and exiting the materials, ballmillls can be divided into two categories: continuous (cantinos) and discontinuous (dis cantinos). In Balmill continuously, unlike the continuous ballmill, the materials are automatically removed from ballmill after finishing the mill.
The role of ballmill liner in general is to protect the ballmill body against abrasion and abrasion. Balmil liner increases efficiency and prevents corrosion damage.
The main materials from which ballmill liners are made include rubber materials, alloy steel or anti-wear cast iron.
