Introduction to White Ash The effective content of white ash we usually refer to refers to the content of calcium oxide (CAO) and magnesium oxide (MGO) contained in white ash. These two substances play a decisive role in the strength of the crushed stone base of fly ash, especially after hydration reaction with fly ash. The influence of their content is more significant. Increasing the lime dosage to a certain extent can naturally improve the crushing of fly ash ..

Introduction to White Ash
The effective content of white ash we usually refer to refers to the calcium oxide (CAO) and magnesium oxide (MGO) contained in white ash The content of these two substances plays a decisive role in the strength of the fly ash crushed stone base, especially after hydration reaction with fly ash. The influence of their content is more significant. Increasing the lime dosage to a certain extent can naturally improve the strength of the fly ash crushed stone base, but this not only increases the construction cost, but also is very unfavorable for improving the crack resistance of the fly ash crushed stone base. Therefore, it is recommended to choose white ash with high effective content as much as possible. It is usually required that the white ash must meet the standard of grade 2 or above, that is, the content of effective calcium and magnesium oxide in white ash must not be less than 80%. This can not only meet the needs of oxidation and hydration forming of the fly ash crushed stone base, ensure the strength of the base, but also improve the stability of the base. It does not affect its crack resistance and is very beneficial for ensuring the quality of the base layer.

In the cylinder section, a conical cylinder has been added at the discharge end of the original cylinder, which not only increases the effective volume of the mill, but also makes the distribution of the medium inside the cylinder more reasonable. This product is widely used for material grinding in non-ferrous metal, black metal, non-metal mining sites, as well as in the chemical and building materials industries. In the production of aerated concrete, it is mainly used for white ash grinding and river sand fine grinding.

Picture of white ash ball mill
Structure of white ash ball mill Hongtong Machinery is one of the large-scale ball mill manufacturers in China. The white ash ball mill produced by the factory has a unique structural design, smooth operation, and the most favorable price among peers. It is a trusted old brand manufacturer of white ash ball mills by many customers.
The Hongtong white ash ball mill consists of main parts such as feeding section, discharging section, rotating section, and transmission section (reducer, small transmission gear, motor, electric control). The hollow shaft is made of cast steel and the inner lining can be replaced. The rotating large gear is processed by casting gear hobbing, and the cylinder body is embedded with wear-resistant lining plate, which has good wear resistance. The machine runs smoothly and reliably. According to the material and ore discharge method, dry ball mill and wet grid ball mill can be selected.

Working principle of white ash ball mill The material is uniformly fed into the first bin of the white ash ball mill through the hollow shaft screw of the feeding device. The bin of the white ash ball mill has stepped or corrugated lining plates, which are filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force, which brings the steel balls to a certain height and then falls down, causing heavy impact and grinding on the material. After the material reaches rough grinding in the first warehouse, it enters the second warehouse through a single-layer partition plate. The warehouse is lined with a flat lining plate and contains steel balls for further grinding of the material. The powdered material is discharged through the discharge grate to complete the grinding operation.
During the rotation of the cylinder, there is also a phenomenon of sliding of the grinding body. In the sliding process, the material is given a grinding effect. In order to effectively utilize the grinding effect, when grinding materials with a particle size of 20 mesh, the grinding body cylinder is divided into two sections by a partition plate, which becomes a double chamber. When the material enters the first chamber, it is crushed by the steel ball. When the material enters the second chamber, the steel end grinds the material, and the qualified material is discharged from the hollow shaft at the discharge end. When grinding materials with small feed particles, such as sand No. 2 slag, coarse fly ash, and white ash, the cylinder of the ball mill can be made into a single chamber cylinder without a partition plate, and the grinding volume can also be made of steel sections.

Performance advantages of white ash ball mill
The reason why Hongtong white ash ball mill sells so well is because its white ash ball mill has incomparable advantages compared to other ball mill manufacturers, which can meet various production needs of customers and create greater economic benefits for you. Let you realize your dream of becoming rich and prosperous on the road of entrepreneurship as soon as possible.
1. The transmission of the white ash ball mill adopts rolling bearings instead of sliding bearings, which greatly reduces friction, makes it easy to start, and significantly saves energy;
2. The discharge end of the white ash ball mill adopts a conical design, which not only increases the volume but also forces the steel balls at the conical end to be graded. The closer they are to the outlet, the smaller the diameter of the steel balls, which increases the effect of repeated grinding and further improves the fineness of the material;
3. The white ash ball mill adopts a groove type annular liner plate, which increases the contact surface between the ball and ore, enhances the grinding effect, and has the ability to lift the ore, reducing power;
4. The white ash ball mill adopts an integral frame, which is convenient for civil construction and equipment installation.

Methods to improve the working efficiency of white ash ball mill
The efficiency of the white ash ball mill directly affects the economic benefits of customers. Therefore, in order to create greater economic value for customers, Hongtong Machinery has accumulated the following five methods to improve the efficiency of the white ash ball mill through years of production practice experience.
1. Deceleration device.
Increasing the rotational speed is the best way to improve the efficiency of the white ash ball mill. As the rotational speed increases, the efficiency naturally improves. Therefore, appropriate improvements to the deceleration device can also have a certain effect, increasing the output per unit time. Conditional beneficiation plants can also choose to install frequency converters to adjust the speed and achieve satisfactory results.
2. Add water quantity.
The moisture in the ore also has a certain impact on the working efficiency of the white ash ball mill. Therefore, increasing the moisture content of the ore in the grinding chamber appropriately can also increase the efficiency of the white ash ball mill.
3. The lining plate of the ball mill.
The mill liner is mainly used to protect the cylinder and avoid direct impact and friction of the grinding body and materials on the cylinder. Different types of liners can adjust the movement state of grinding bodies in each compartment to achieve the best results.
4. Current.
For rotary dryers, increasing the current is to increase the speed. As the speed increases, the efficiency of the white ash ball mill naturally increases. The power of the motor should be roughly determined based on the tonnage of the grinding material loaded. However, it should be noted that increasing the current must be within the rated power range of the white ash ball mill and cannot exceed the maximum load. If the current is too high, it will burn out the mill and cause significant losses.
5. Ball stones.
It should be noted that the matching of ball diameters is also important here. To make the diameter of the ball stone vary, it is necessary to fully grind the ores of different sizes in the grinding chamber, which can also improve the working efficiency of the white ash ball mill.
