The vertical mill is an advanced grinding equipment designed and developed based on the extensive use of advanced technologies at home and abroad, combined with years of experience in the production of various mills and vertical mills. It is an ideal equipment in the milling industry that integrates crushing, drying, grinding, and grading conveying. It can be widely used in cement, electric power, metallurgy, chemical, non-metallic mining and other industries. It is used to grind block, granular and powdery materials into required powdery materials. Raymond machine manufacturers

Main structureedit


The vertical mill is mainly composed of a powder separator, a grinding roller device, a grinding disc device, a pressure device, a reducer, a motor, and a shell. The separator is


Vertical mill


Vertical mill


An efficient and energy-saving powder selection device. Grinding rollers are used to crush materials. The grinding disc is fixed on the output shaft of the reducer, where the grinding roller crushes the material. The pressure device is a component that provides grinding pressure to the grinding roller, and provides enough pressure to the grinding roller to crush the material.


Working principleedit


When the vertical mill is working normally, the motor drives the grinding disc to rotate through the reducer, and the material falls into the center of the grinding disc from the inlet through the lock air feeder, and hot air enters the mill from the air inlet. With the rotation of the grinding disc, the material moves to the edge of the grinding disc under the action of centrifugal force. When passing through the annular groove on the grinding disc, it is crushed and crushed by the grinding roller. The crushed material is carried by the wind ring high-speed airflow at the edge of the grinding disc. The particles directly fall on the grinding disc and re-grind. When the material in the airflow passes through the upper separator, under the action of the rotating rotor, the coarse powder falls from the cone to the grinding disc and re-grinds. The dust collection device is the product. The material containing moisture is dried in the contact process with the hot air flow. By adjusting the temperature of the hot air, it can meet the requirements of materials with different humidity and reach the required product moisture. By adjusting the separator, the required thickness of different products can be achieved.


Main featuresedit


Low investment cost


As it integrates crushing, drying, grinding, and grading and conveying, the system is simple, the layout is compact, and the floor space is about 50% of the ball mill system, and it can be

 The open-air layout can greatly reduce investment costs.


Low operating cost


⑴High grinding efficiency: The grinding roller is used to directly grind the ground material on the grinding disc, which has low energy consumption and saves energy consumption by 30%-40% compared with the ball mill system.


⑵ Less wear: Because the grinding roller does not directly contact the grinding disc during work, and the grinding roller and liner are made of high-quality materials, it has a long service life and less wear.


Strong drying capacity


Because the hot air directly contacts the materials in the mill, the drying capacity is strong, and energy is saved. By adjusting the temperature of the hot air, the requirements of materials with different humidity can be met.


Easy operation


⑴ Equipped with automatic control system, which can realize remote control and easy operation.


⑵Equipped with a device to prevent direct contact between the roller sleeve and the grinding disc liner, avoiding destructive impact and severe vibration.


Stable product quality


Because the material stays in the mill for a short time, it is easy to detect and control the particle size and chemical composition of the product, reduce repeated grinding, and stabilize the product quality.


Easy to maintain


It is convenient and quick to replace the roller sleeve and liner by overhauling the oil cylinder, turning the boom, and reducing downtime loss.


Environmental protection


The vibration is small, the noise is low, and the equipment is sealed as a whole. The system works under negative pressure, no dust spills, and the environment is clean, meeting national environmental protection requirements.
