Three separation powder selection machine is a device used in the field of food processing, mainly used to separate and screen impurities or materials of different particle sizes in powdered materials, in order to obtain products that meet the requirements. Its working principle mainly includes several key components such as material feeding, separation screen, vibration device, and aggregate port. The following will provide a detailed introduction to the working principle of the three separation powder selection machine.

Material feeding: The initial working step of the three separation powder selection machine is to input the material to be processed into the equipment through the feeding port. Materials can be in the form of powder, granules, or mixtures of particles and powders, such as flour, starch, pharmaceutical powders, etc. The input method of materials can be determined based on the structural design of specific equipment, usually using vibration feeding method, which uses vibration force to feed materials from the feeding port into the material slot of the separation screen.

Separation screen: The separation screen is one of the core components of the three separation powder concentrator, consisting of multiple layers of metal mesh, with fixed spacing between each layer of mesh, forming a series of sieve holes. The size of the sieve hole is designed according to the process requirements, which can screen out materials with a particle size range within a certain range. The screen material should have characteristics such as wear resistance, high temperature resistance, and corrosion resistance to ensure the service life and screening effect of the equipment.

Vibration device: The vibration device is a component used to generate vibration force and plays a crucial role in the three separation powder selection machine. It mainly consists of vibration motors, vibrators, and vibration springs. The vibration motor converts electrical energy into mechanical vibration energy, driving the vibrator to produce reciprocating vibration. The vibration spring plays a role in shock absorption and support, allowing the vibration to be transmitted to the separation screen and evenly distributing the material on the screen.

Separation process: After the material enters the separation screen, due to the vibration device, the material will be evenly distributed on the screen and move forward with the vibration of the screen. During the movement process, materials with different particle sizes and shapes will be subjected to different forces, resulting in a layering effect on the screen. Large particle materials will move forward in a straight line due to inertia, thus being separated onto a larger sieve layer; Small particles and powdery materials will be intercepted by the sieve holes, leaving them on the surface of the finer sieve holes. As a result, the material produces a classification and separation effect on the sieve.

Aggregation port: By setting the size of the sieve hole and vibrating the sieve, materials of different particle sizes are separated and concentrated on their respective sieve layers. Then, these materials will move along the slope or channel of the sieve to the aggregate opening. The aggregate port is the discharge port of the equipment, and multiple aggregate ports can be set as needed to achieve the separation or separation of materials with different particle sizes, thus meeting different process requirements.

Cleaning system: During the working process, continuous particle size and impurity separation may occur due to the vibration and movement of materials. In order to ensure the normal operation of the equipment and the quality of the product, the three separation powder concentrator is usually equipped with a cleaning system. The cleaning system includes air blowing and water washing, which remove residual materials and impurities from the screen by spraying air or water to maintain the smoothness and screening effect of the screen.

In summary, the three separation powder selection machine classifies and separates the granular powder materials in the mixture according to their particle size through the synergistic effect of several key components such as material feeding, separation screen, vibration device, and aggregate port, in order to obtain products that meet the requirements. Its working principle is simple and intuitive, but through reasonable design and optimization, efficient and stable separation effects can be achieved.
