working principle
The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The cylinder is a long cylinder with a grinding body inside the cylinder. The cylinder is made of steel plate, with a steel liner fixed to the cylinder, and the grinding body Generally, it is a steel ball, which is packed into the cylinder according to different diameters and a certain proportion. The grinding body can also be a steel section.
Choose according to the particle size of the grinding material. The material is loaded into the cylinder by the hollow shaft at the feed end of the ball mill. When the cylinder of the ball mill rotates, the grinding body is attached to the cylinder liner due to inertia, centrifugal force and friction. Carried away by the cylinder, when it is brought to a certain height, it will be thrown down due to its own gravity. The falling grinding body will crush the material in the cylinder like a projectile.
The material enters the first chamber of the mill uniformly through the feeding device through the hollow shaft of the feeding device. There is a step liner or a corrugated liner in the first chamber of the mill. The chamber is equipped with steel balls of various specifications. Falling after the height has a heavy blow and grinding effect on the material. After the material reaches the rough grinding in the first warehouse, it enters the second warehouse through the single-layer partition board. The warehouse is lined with flat liners and steel balls to further grind the materials. The powder is discharged through the discharge grate to complete the grinding operation.
When the cylinder is rotating, the grinding body also slips off. During the sliding process, the material is grinded. In order to effectively use the grinding effect, when grinding the material with larger particle size, the grinding body is fine. Divided into two sections by a partition board, it becomes a double silo. When the material enters the first silo, it is crushed by the steel ball. When the material enters the second silo, the steel section grinds the material, and the ground qualified material is hollow from the discharge end. When the shaft is discharged to grind the materials with small feed particles, such as sand No. 2 slag, coarse fly ash, the barrel of the mill can be formed as a single-chamber barrel mill, and the grinding body can also be made of steel.
The raw materials are fed into the hollow cylinder through the hollow shaft neck for grinding. The cylinder is equipped with various diameters of grinding media (steel balls, steel rods or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, the medium and raw materials contained in the cylinder will be separated from the cylinder when the cylinder reaches a certain height under the action of centrifugal force and frictional force. The inner wall is projected to fall or roll down, crushing the ore due to the impact force. At the same time, during the rotation of the mill, the sliding motion between the grinding media also has a grinding effect on the raw materials. The ground material is discharged through the hollow journal.
Mechanical structure
The ball mill is composed of feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor, electric control) and other main parts. The hollow shaft is made of cast steel, and the inner lining is removable. The large rotary gear is processed by casting gear hobbing. The cylinder is inlaid with wear-resistant liners, which has good wear resistance. The machine runs smoothly and works reliably.
The main body of the ball mill includes a cylinder, in which a lining made of wear-resistant materials is inserted in the cylinder, there are bearings that carry the cylinder and maintain its rotation, and there are driving parts such as a motor, transmission gears, pulleys, and V-belts.
As for the parts called blades, they are generally not the main components. The internal spiral blades in the component inlet of the feed end can be called internal spiral blades, and the internal spiral blades in the component outlet of the discharge end can also be called internal spiral blades.
In addition, if a screw conveyor is used in the auxiliary equipment at the discharge end, there will be parts called spiral blades in the equipment, but strictly speaking, it is no longer a part of the ball mill.
According to the material and discharging method, dry ball mill and wet grid type ball mill can be selected. The energy-saving ball mill adopts self-aligning double-row radial spherical roller bearings with low running resistance and significant energy-saving effect. In the barrel part, a section of conical barrel is added at the discharge end of the original barrel, which not only increases the effective volume of the mill, but also makes the medium distribution in the barrel more reasonable. This product is widely used in non-ferrous metals, ferrous metals, non-metallic mineral processing plants, chemical and building materials industries for material grinding.
Application:Ball mill accessories
Ball mill accessories include ball mill gear, ball mill pinion, ball mill hollow shaft, ball mill gear ring, ball mill gear ring, ball mill steel ball, ball mill compartment plate, ball mill transmission device, ball mill bearing, ball mill end lining, and so on.
The material selection of the big gear of the ball mill:
Big gear of ball mill
Big gear of ball mill
According to the working conditions of large gears, the following materials are commonly used for large gears: (1) Medium carbon structural steel (2) Medium carbon alloy structural steel (3) Carburized steel (4) Nitrided steel
The structure of the big gear of the ball mill has a variety of different shapes due to different usage requirements, but from the technological point of view, the gear can be regarded as composed of two parts: the ring gear and the wheel body. According to the distribution of gear teeth on the ring gear, it can be divided into straight teeth, helical teeth, and herringbone teeth.
Features:Improve efficiency
(1) Increase effective volume
Increasing the effective volume of the mill can increase the productivity of the mill compared with the same period of the previous year. The thick liner and heavy weight increase the power consumption, reduces the effective volume of the cylinder, and reduces the production efficiency of the ball mill. If the magnetic liner is selected, the effective volume of the cylinder can be increased, while the weight is relatively reduced, and the power consumption is reduced. However, the use of thinner magnetic liners also has certain disadvantages. Due to the small thickness, the anti-hit ability is not as good as the existing Cr-Mn-Mo alloy cast steel liners, which are prone to cracking problems. For example, in response to the problem of lining board, some manufacturers use grooved ring-shaped lining board, which increases the contact surface of ball ore, strengthens the grinding effect, and has the ability to lift ore, reduces energy consumption, and is widely used.
(2) Increase the filling rate and rotation rate
The processing capacity of the ball mill increases with the increase of the filling rate of the steel balls. Increasing the filling rate increases the probability of the steel balls to grind the ore and the self-grinding effect of the ore. When the filling rate of steel balls is 45%, the load of the ball mill is the maximum, and when the filling rate exceeds 45%, the load is greatly reduced with the increase of the filling rate. This is mainly because as the filling rate increases, the starting point of the steel ball is raised, the impact point of the falling steel ball is accelerated to approach and exceed the center of rotation, and the resultant moment is greatly shortened and becomes 0 to a negative value. The load required for the impact resultant moment of the steel ball (containing ore) falls from large to 0, until it becomes the driving force for the rotation of the cylinder (that is, the resultant force point exceeds the center, and the resultant moment is negative).
(3) Change the shape of the grinding medium
An elliptical sphere medium can be used to replace the current sphere medium. Compared with a round sphere, the elliptical sphere has the following advantages:
Compared with the round sphere, the ellipsoidal sphere can greatly improve the crushing and grinding capacity of the ball mill, and at the same time, it also reduces the equipment loss.

Tubular ball mill
After the material is crushed, it is the key equipment for crushing.
Superfine laminated mill
The superfine laminated ball mill is the most famous high-efficiency and energy-saving mill, and it is also the first mill in China.
1 ultra-fine laminated ball mill = crushing and screening system + 1/2 grinding and grading system
The superfine laminated self-grinding machine truly realizes "more crushing and less grinding". After adopting the superfine laminated self-grinding machine, the comprehensive benefits are significant: the medium and fine crushing and screening plant and equipment are omitted, and the dust removal unit is omitted. Take a ton/day concentrator as an example, it can save investment of more than 2-10 million yuan and save energy by 20-30%. It is a veritable dust-free crushing and grinding energy-saving and environment-friendly beneficiation process.
Cone ball mill
Conical ball mill is a common type of ball mill in ore dressing production. This machine changes the original structure of the mill, integrates the machine body and the chassis, and can be placed on the foundation plane at one time during installation. The main bearing adopts double-row spherical rollers. For sub-bearings, energy can be reduced by 30%, fine particle size can be improved, and processing energy can be increased by 15-20%. Cone ball mill is the key equipment for crushing materials after crushing. Ball mills are widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics, etc., for dry or wet grinding of various ores and other grindable materials. This machine is a horizontal cylindrical rotating device with outer gear drive, two bins, and a lattice type ball mill.
Ceramic ball mill
Ceramic ball mill is the key equipment for crushing materials after crushing. Ball mills are widely used in cement, silicate products, dry or wet grinding of various ores and other grindable materials. The ball mill is a horizontal cylindrical rotating device, driven by an outer gear, two bins, and a grid type ball mill.
Intermittent ball mill
Intermittent ball mill is the key equipment for crushing materials after crushing. Ball mill wide
It is widely used in the production industries of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, and glass ceramics. It is used for dry or wet grinding of various ores and other grindable materials. External gear drive, two bins, lattice type ball mill.
Folding overflow ball mill
With the rotation of the barrel and the movement of the grinding medium, the overflow type ball mill gradually spreads to the right after crushing materials such as ore, and finally overflows from the hollow journal on the right, hence the name.
Lattice ball mill
The grid type ball mill is equipped with a grid plate at the discharge end, which is composed of several fan-shaped orifice plates. The width of the grid hole is 7mm-20mm. The ore enters the space between the grid plate and the end cover through the grid hole. The lifting plate lifts the material upward, and the material slides down along the lifting plate, and then passes through the tapered block to the right to the hollow shaft journal and is discharged out of the machine.
Wind discharge ball mill
The material of the wind discharge ball mill enters the ball mill from the feed port. After the grinding medium impacts and grinds the material, the material gradually moves from the inlet of the mill to the outlet, and the outlet end is connected with the air pipe. In the system, a separator and powder selection are connected in series. At the inlet of the machine, dust collector and fan, when the wind discharge starts to operate, the ball mill body is relatively under low negative pressure. After crushing, the ground material enters the pipeline system from the discharge port with the wind. After the coarser particles are separated, they are sent to the inlet of the ball mill again, and the ground materials are separated and recovered by the separator.
Double chamber ball mill
After passing through the hollow shaft neck, the material of the double-chamber ball mill does not directly enter the medium containing the grinding balls in the cylinder, but when the cylinder rotates around the horizontal axis at a certain speed, the further sorting action starts, so that the bulk material falls into The crushing bin and the small pieces of material enter the grinding bin through the conveying device. In this way, when their own gravity is greater than the centrifugal force, they will break away from the inner wall of the cylinder and splash or roll down, so that the impact force generated on the liner will be targeted for crushing according to the different needs of different chambers.
Energy-saving ball mill
Energy-saving ball mill is the key equipment for crushing materials after being crushed. Energy-saving ball mills are widely used in cement, silicate products, dry or wet grinding of various ores and other grindable materials. This machine is a horizontal cylindrical rotating device with outer gear drive, two bins, and a lattice type ball mill.

Problem handling
The bearing position and bearing chamber of the ball mill reducer, under heavy load, low speed, heavy load and high speed, high torque start, and under the action of equipment vibration and radial impact, metal fatigue occurs in the bearing chamber or bearing position, resulting in permanent deformation; inside the bearing There is a clearance fit between the ring and the shaft or the outer ring of the bearing and the bearing chamber, resulting in wear due to relative movement. Once this problem occurs, it will seriously affect the normal production of the equipment. If the bearing chamber of the reducer of the ball mill is worn, it is difficult to repair and solve this type of problem on the spot by traditional methods. Outsourcing repair is limited by the material and wear size of the parts. It is difficult to repair, usually by replacing the new parts. Quickly, component stocking takes up huge amounts of money. In the 21st century, developed countries mostly use polymer composite materials for on-site repair, among which the more mature Blessing World Blue technology system. For different equipment, different operating conditions, and different wear conditions, the corresponding repair process can be used to repair quickly, simply and effectively. Especially due to the concession of polymer materials, 100% of the contact area is always maintained, which avoids the generation of matching gaps. The service life of the repaired equipment is even longer than that of the new equipment, which fundamentally solves the problem of shaft wear of the ball mill.
Specific ball mill application case: Equipment name: ball mill reducer, model: LDH80-6.74, speed ratio: 6.74, input shaft speed: 992 rpm, bearing chamber diameter: 400mm, bearing width: 106mm, and the wear depth is about 0.5mm. The bearing hole of the output shaft of the reducer of the coal pulverizer is worn out, and the upper and lower parts of the bearing chamber are worn to different degrees, and the number of wear is 4 bearing chambers. Equipment value: several hundred thousand yuan for the reducer housing. Equipment problem: 4 bearing chambers of low-speed shafts of 2 reducers are worn out. Solution: Metal repair 2211F polymer composite material has excellent adhesion, pressure resistance and various comprehensive properties. By using the bearing chamber as the reference of the wear surface and the corresponding relationship between the bearing and the bearing chamber, the construction can be done quickly and quickly. Worn bearing chambers can be repaired online to avoid scrap replacement and prolong the service life of the equipment. Polymer composite materials and application technology can enable enterprises to quickly and effectively repair on-site in the first time, effectively avoiding the loss of benefits due to long-term equipment shutdowns and production shutdowns; effectively avoiding transportation costs, lifting costs, and construction safety. Comprehensive factors ensure personal safety and corporate losses, saving the company valuable production time.
Installation matters
The ball mill should be installed on a solid concrete foundation. For the basic design and construction of the ball mill, please refer to the ball mill assembly drawing and foundation drawing. In order to ensure that the position accuracy of each component of the ball mill does not change greatly during use, the foundation of the ball mill should adopt a monolithic structure.
The ball mill can be installed on the concrete foundation after the compressive strength reaches more than 75%. Prior to installation, the quality of the foundation should be inspected. It is required that the concrete has no defects that affect the strength, the number and location of the reserved holes meet the requirements, and there is no debris, water, and oil in the reserved holes. When the "ground wire method" is used for installation, the "center target plate" should be pre-embedded on the surface of the foundation. Before installation, draw all centerlines on the foundation and make eye-catching punch marks on the "center target" as the centerline reference during installation.
Before hoisting, the ball mill should be fully inspected and accepted in different parts, and problems should be dealt with in time.
1. Refer to the assembly drawing of the main bearing components for the specific requirements of the main bearing part.
2. Refer to the assembly drawing of the rotating part for the cylinder part.
3. For the transmission part, please refer to the assembly drawing of the transmission part.
4. Refer to the assembly drawing for the overall relative position.
Correct operation steps
1. Before turning on the equipment, we first need to check the lubrication conditions between the mechanical parts. After confirming that all preparations have been completed, first start the discharge device of the ball mill, the total power supply of the ball mill, and finally the feeding device.
2. Before the material enters the box, first check whether the steel spheres installed in the box are set and whether the quantity is appropriate. 3. After the ball mill is turned on, it must be tested in an empty box first. After ensuring that the contact surface between the box body and the mechanical parts is sealed and well lubricated, the operation can be started. 4. In addition, the start of the ball mill is coordinated with the personnel of other working positions. The personnel who operate the machine must see the corresponding command signal before proceeding. 5. The discharge port can only be closed after confirming that the material and the feed port are stopped. 6. The maintenance of equipment should be timely, reasonable and comprehensive. After the ball mill is completely stopped, the grinding media in the box needs to be carefully cleaned to extend the service life of mechanical equipment and reduce industrial costs.
