A vertical mill is a machine used to grind or grind materials, usually used to manufacture industrial products or process raw materials. It can grind and grind a variety of materials, including metals, non-metals, ores and chemical raw materials.

Structure:

The main structure of the vertical mill includes components such as the body, grinding disc, grinding roller, drive system, feeding system and classification system. Among them, the grinding disc and grinding roller are the most important parts of the vertical mill. They are made of high-strength alloy and can withstand the impact and wear during high-speed rotation.

Main structure: The main structure of the vertical mill includes components such as the body, grinding disc, grinding roller, drive system, feeding system and classification system.

Grinding disc: The grinding disc is the main working part of the vertical mill. It is generally composed of a pair of horizontally arranged discs, on which grinding rollers or grinding balls are installed. They are made of high-strength alloy and can withstand the impact and wear during high-speed rotation.

Transmission system: The vertical mill is equipped with a transmission system, including a motor, a reducer and a transmission device, which is used to drive the rotation of the grinding disc.

Working principle:

The working principle of the vertical mill is to add the material from the feed system into the grinding disc. The material is squeezed, ground and sheared by the high-speed rotating grinding roller in the grinding disc. After multiple grindings, the material will be ground into the required particle size, and then the required particles will be separated through the classification system.

Feeding and grinding: The raw material enters the grinding disc of the vertical mill through the feed port. Under the action of the grinding disc, it is ground and crushed by the pressure and friction of the grinding roller or grinding ball. The rotation of the grinding disc causes the raw material to be subjected to strong friction and shear force on the grinding disc, thereby achieving the effect of fine grinding.

Grading and discharge: After grinding, the finely ground material is graded through a screen or air flow classification system and divided into different particle size levels according to the size of the particle size. The finer particles are discharged from the bottom of the screen or classification system, while the coarser particles are re-sent to the grinding disc for re-grinding.

Circulation and circulating air: In order to improve the grinding effect and control the temperature of the mill, the vertical mill usually adopts a circulating air system. A part of the gas is introduced into the vertical mill through the fan to form an air circulation, thereby taking away the heat and fine powder and maintaining the temperature and humidity inside the mill.
