Ball mills are widely used for ball mills in industries such as cement, mining, building materials, chemicals, food, compound fertilizers, etc. In order to control the temperature of the ball mill, thermocouples are installed on the in-outlet and out-feed devices, and the temperature of the ball mill can be displayed through the temperature meter. This provides a basis for better control of the operating temperature in the barrel (typically 350-380 degrees).
Cement ball mill is the key equipment after the material is ball milled and then crushed. It is one of the high-fine grinding machines widely used in industrial production. There are many types, such as cement ball mill, energy-saving ball mill, cement ball mill and so on. The ball mill is suitable for grinding a variety of ores and other materials and is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. Ball mills are widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass-ceramic industries, and dry or wet grinding of various ores and other abrasive materials.
The cement ball mill is a horizontal cylindrical rotating device with external gear drive, two positions and a lattice type ball mill. The material is fed into the mill silo uniformly by the feeding device through the hollow shaft of the feeding material. There is a step liner or a corrugated liner in the silo, which contains steel balls of different specifications. The cylinder rotates to generate centrifugal force and brings the steel ball to a certain height and then falls. , Produce heavy blow and grinding effect on the material. After the material reaches rough grinding, it enters the second bin through a single-layered barrier plate. The bin is set with a flat liner and contains steel balls to further grind the material. The powder is discharged through the discharge ramp.
1. The multi-stage counter cavities of the cement ball mill have enough ball milling space and are suitable for ball milling of large materials. The angle of the counter-attack plate of the cement ball mill can be adjusted to ensure that the material appears a proper angle when the impact between the counter-attack plate and the rotor is repeated, and the ball mill efficiency can be effectively improved. Stepping back to the ball milling process can effectively reduce the energy consumption during the ball milling process.
2. The counter-attack board adjustment system also doubles as the overload protection device of the whole machine. When the foreign matter (such as iron, etc.) or non-spherical material block enters the ball mill, the counter-attack board can automatically rebound and bounce, allowing foreign matter to pass through the ball mill and prevent foreign matter (such as Iron blocks, etc., or non-spherical blocks cause damage to the equipment.
3. The plate hammer is firmly fixed on the rotor, so the starting torque of the ball mill is small, the dynamic balance performance of the rotor part is easy to control, and the disturbance is small during operation. Smooth start.
(1) Crushing and impacting are adopted for hard materials with large or medium grain size, and teeth with different shapes are included in the crushing tools; for example, ball mills with ball mills, ball mills with tooth rolls, etc. (2) Smaller-size and hard materials are crushed and impacted. , Grinding, crushing tool surface without teeth, is smooth; such as the roller ball mill (3) powdery or mud-like materials using grinding, impact, crushing; such as ball mill (4) weak abrasive material using impact , blow, grinding, grinding tools with sharp teeth; 4. The rack part is a three-part structure, only to open the ball mill rear housing, you can replace the hammer, counterattack board, lining board repair and maintenance operation.
5. The interchangeability of parts is strong and the variety of wearing parts is small, which facilitates the procurement and management of spare parts. The hydraulic opening device is used to open and close the housing, which can effectively reduce maintenance labor intensity, improve maintenance work efficiency, and shorten maintenance work time.
6. The monitoring system can monitor the running status of the ball mill at any time. The monitoring signal can be interlocked with the main control system to ensure the safe and reliable operation of the machine.
7. The drive system adopts the motor + mechanical coupling + V-belt + ball mill, which can effectively improve the motor start-up performance and enable the motor to run smoothly. The belt transmission method can double the function of overload protection, the motor power required by the drive system is low, and the running cost is greatly reduced. This drive solution is a practical, high-performance, safe and reliable drive solution.
Before selecting the comminution equipment, the squeezing force should be clearly clarified. According to the material properties of the granules, the particle size, and the requirements of the crushed products, the corresponding urging method should be adopted, and then the smashing equipment type should be obtained.
(5) The abrasive material is mainly made of crushing, and the surface of the crushing tool is smooth; (6) The ductile material is sheared or quickly blown; For example, the hammer mill (7) uses multi-component materials for impact. Under the choice of crushed, you can also use a variety of force fields.
Rotary ball mill is a material heating and drying device. The material in the rotating cylinder of the coaxial sleeve row is ball-milled by the process of folding back and lifting the spiral blade and the intermittent spiral lifting plate between the inner and outer cylinders. The sleeve sleeve structure can shorten the length of the ball mill, and the heat dissipation surface is greatly reduced, so that the heat consumption is reduced, and the doubled heat exchange surface greatly enhances the heat efficiency. For materials that cannot touch the smoke, multi-cylinder rotary ball mills provide inner smoke pipes and annular smoke pipes respectively in the inner and outer barrels. Each smoke pipe communicates with a radial flue, which is also energy-efficient. It is easy to see that for hot and cold media, the machine becomes a tandem rotary cooler.
