Introduction to slag
The residue of ore after beneficiation or smelting is called slag. Slag can be reused through a slag ball mill. In industrial production, slag plays an important role, especially in some major factories. Extracting and processing slag into slag cement, slag micro powder, slag powder, slag silicate cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, and slag vertical mill. Saved energy consumption. In addition, blast furnace slag can also be used as raw materials for casting stones, microcrystalline glass, fertilizers, enamel, ceramics, etc.
Slag grinding technology
1. Co grinding of slag, clinker, and gypsum;
2. Slag is ground separately and then mixed with fine powder of clinker and gypsum to form cement;
3. Slag is pre ground separately and then ground together with clinker and gypsum. However, due to the use of the first grinding process technology, slag is easily concentrated in the coarse powder during grinding, and only serves as a mixing material.

Scope of application of slag ball mill The slag ball mill is a key equipment for crushing materials before further crushing. It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics, for dry or wet grinding of various ores and other grindable materials.

Structure of slag ball mill Our Hongtong Machinery Factory in Gongyi City is a professional manufacturer of slag ball mills. The factory regards quality as life and reputation as the foundation. The slag ball mills produced have high cost-effectiveness, a wide range of applicable materials, reasonable structure, and good crushing effect. We are well-known in the same industry and are an excellent ball mill manufacturer recognized by customers.
The slag ball mill is composed of main components such as feeding section, discharging section, rotating section, and transmission section. The transmission section has a complex structure and consists of four parts: reducer, small transmission gear, motor, and electric control; The host includes a cylinder, bearings that support the cylinder and maintain its rotation, as well as driving components such as an electric motor, transmission gears, pulleys, and V-belts. The slag ball mill is composed of a horizontal simplified body, a hollow shaft for feeding and discharging, and a grinding head. The simplified body is a long cylinder with a grinding body inside. The cylinder is made of steel plate and has a steel lining plate fixed to the simplified body. The grinding body is generally a steel ball, which is loaded into the cylinder according to different diameters and certain proportions. The grinding body can also be made of steel sections; Regarding the parts called blades, they are not considered as the main components. If there is an internal spiral in the inlet of the component at the feeding end, it can be called an internal spiral blade. If there is an internal spiral in the outlet of the component at the discharging end, it can also be called an internal spiral blade; If a spiral conveyor is used in the auxiliary equipment at the discharge end, there will be parts called spiral blades in the equipment, but strictly speaking, they are no longer considered as parts of the ball mill.
In addition, the hollow shaft is made of cast steel, and the inner lining can be replaced. The rotating large gear is processed by casting hobbing, and the cylinder body is embedded with wear-resistant lining plates, which have good wear resistance; These conditions make the slag ball mill operate smoothly and reliably.

Working principle of slag ball mill Materials can only be thoroughly mixed and interact with each other after being ground to the required fineness, in order to achieve maximum strength in the finished product. According to the particle size selection of the grinding material, the material is loaded into the cylinder by the hollow shaft at the feeding end of the slag ball mill. When the slag ball mill cylinder rotates, the grinding material is carried away by the cylinder due to inertia and centrifugal force, and the frictional force is close to the cylinder lining plate. When it is brought to a certain height, it is thrown down due to its own gravity, and the falling grinding material shatters the material inside the cylinder like a projectile. The material is uniformly fed into the first compartment of the mill through the feeding device and the hollow shaft screw. There are stepped or corrugated liners in this compartment, which are equipped 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 drops them, causing heavy impact and grinding on the material. After rough grinding is completed in the first warehouse, the material enters the second warehouse through a single-layer partition plate, which is lined with a flat lining plate and contains steel balls for further grinding. The powder material is discharged through the discharge grate, completing the grinding process.
During the rotation process of the cylinder, if there is a sliding phenomenon of the grinding body, the material will be ground during the sliding process. In order to effectively utilize the grinding, for the general 20 mesh grinding of materials with larger particle size, the slag ball mill cylinder is divided into two sections with a partition plate, forming a double compartment. When the material enters the first compartment, it is crushed by the steel ball for rough grinding. When the material enters the second compartment, the steel ball grinds the material, and the qualified material after grinding flows out from the hollow shaft at the discharge end. For grinding materials with small feed particle size, the slag ball mill cylinder can be converted into a single chamber grinding cylinder without a partition.

Advantages of slag ball mill
1、 Advantages of slag ball mill system
The slag ball mill has sufficient starting torque during use to meet the requirements of large loading capacity of the slag ball mill, and to ensure that the equipment operates smoothly under variable frequency, ensuring that the motor has constant torque characteristics. The transformation of the original slag ball mill drive system using a frequency conversion speed control system meets the normal operation of the slag ball mill at low speeds, ensures normal process control requirements, and extends its service life.
2、 Advantages of slag ball mill components
The main bearing of the slag ball mill adopts double row radial spherical roller bearings, which can reduce the weight of the mill and friction torque, while ensuring automatic centering; The power of the electric motor is reduced by 20-40% compared to conventional mills; The large gear is installed at the connection between the cylindrical body and the cone, which improves the stress situation of the main bearing part, reduces the twisting stress of the cylinder, and correspondingly reduces the gear module and diameter, thereby reducing the self weight and load of the slag ball mill.
3、 Performance advantages of slag ball mill
The slag ball mill has the characteristics of high grinding efficiency, high efficiency and energy saving. It changes the traditional structure of the mill, integrates the machine body and chassis, and can be hung on the foundation plane at once during installation, saving labor and time; Improving the hydrodynamic performance and lubrication status of gear transmission has enhanced the operational reliability of slag ball mills.
4、 Advantages of slag ball mill grinding medium
Based on the customer's feed and product particle size requirements, we will provide the most suitable grinding medium to provide you with the best grinding effect. The grinding medium of slag ball mill includes wear-resistant steel balls, high alumina balls, steel bars, etc. The three types of slag ball mill grinding media all have the characteristics of high grinding rate, low energy consumption, and wear resistance, especially wear-resistant steel balls, which have high strength and hardness. Even after wear, they still maintain their original shape, are wear-resistant, corrosion-resistant, and have a long service life.
