Grinding machine is a commonly used industrial equipment for processing and grinding various materials, such as metal, porcelain, glass and so on. It can grind the raw material into the desired fine powder or granular material through friction and collision. The working principle of the grinder will be described in detail below.
1. The structure of the grinder
The grinding machine is mainly composed of a motor, a transmission device, a grinding medium, a grinding cylinder and a control system.
- Motor: The motor of the grinder is the key component to provide power, which converts electrical energy into mechanical energy through the transmission device to drive the grinding machine to rotate.
- Transmission device: the transmission device includes belt, gear, etc., which is used to transfer the speed of the motor to the lapping cylinder so that it can rotate.
Grinding medium: The grinding medium is the material that plays the role of grinding in the grinding machine, and the common grinding medium is steel ball, steel rod, sand and so on.
Grinding cylinder: Grinding simple is the container that contains the grinding medium and raw materials in the grinding machine, which makes the grinding medium and raw materials friction and collision through rotation, so as to achieve the purpose of grinding.
Control system: The control system is used to control the operation of the grinding machine, including starting, stopping, speed regulation and other functions.
2. The working process of the grinder
The working process of the grinder can be divided into three stages: loading, grinding and unloading.
Loading: First, put the raw material to be ground and the appropriate amount of grinding medium into the lapping cylinder. Some grinding additives can be added according to the need to improve the grinding effect.
Grinding: After starting the grinding machine, the motor drives the grinding simple rotation through the transmission device. The grinding medium and the raw material are constantly friction and collision in the grinding sheet, so that the raw material is gradually ground into the required fine powder or granular material. The time and speed of grinding can be adjusted as needed.
Discharge: When the grinding is complete, stop the operation of the grinding machine. Open the discharge port of the grinding cylinder and pour out the ground material.
3. The working principle of the grinder
The working principle of the grinder mainly involves the friction and collision between the grinding medium and the raw material.
- Friction: The grinding medium and raw materials continuously rub against the grinding wall and other grinding media during the rotation process of the grinding sheet. Under the action of friction, a film on the surface of the raw material is worn away, making the raw material gradually finer.
Collision: During the rotation of the grinding medium and the raw material in the grinding cylinder, there will be a collision between them due to the role of centrifugal force. Under the action of collision, the particles of the raw material will be impacted and crushed by the grinding medium, so as to achieve the effect of grinding.
In addition, the working effect of the grinder is also affected by the choice of grinding medium, the shape and size of the grinding cylinder, the filling ratio of the grinding medium and the raw material. According to different requirements, different types of grinding machines can be selected for grinding.
In SUMMARY:
The grinding machine grinds the raw material into the desired fine powder or granular material through the friction and collision between the grinding medium and the raw material. Its working principle mainly involves the friction and collision between the grinding medium and the raw material. The working process of the lapping machine includes three stages: loading, grinding and unloading. The working effect of the grinding machine is affected by many factors, such as the choice of grinding medium, the shape and size of the grinding cylinder. According to different requirements, different types of grinding machines can be selected for grinding.
