Drying sand vibrating screen

Drying sand vibrating screen is a vibrating screening device specially used for screening dried sand. It is mainly used for screening and grading sand and gravel particles to remove impurities and control the particle size. The dried sand is usually used in the construction, casting, glass and other industries. It separates the dried sand of different particle sizes through the exciting force generated by the vibration motor, making the material on the screen jump, thus realizing the screening and grading equipment, separating the dried sand of different particle sizes to meet different application requirements.

What is the principle of drying sand vibrating screen?

Drying sand vibrating screen uses the exciting force generated by the vibration motor to make the drying sand particles on the screen surface jump in the vertical direction and throw in the horizontal direction. Particles smaller than the screen aperture pass through the screen and fall into the discharge port below, while particles larger than the screen aperture are retained on the screen surface and discharged from another discharge port.

The structure of drying sand vibrating screen

Screen frame: usually made of carbon steel or stainless steel, with sufficient strength and rigidity.

Screen: select screens with different apertures and materials according to the screening requirements.

Vibration motor: provides vibration power and is the core component of screening.

Shock absorber: reduces the impact of vibration on the equipment and the surrounding environment.

Feed inlet and discharge outlet: set according to the number of screening layers and particle size requirements.

What are the disadvantages of drying sand vibrating screen?

1. Limited drying effect: The drying effect is affected by the hot air temperature, wind speed and material residence time. If the parameters are not set properly, uneven drying or over-drying may occur. For some special materials, the drying process may destroy the material properties. For some special high-precision screening tasks, the screening accuracy of the drying sand vibrating screen may be limited and cannot meet the needs of all application scenarios.

2. High requirements for material properties: For sand with high viscosity or high water content, the screen is easy to clog, affecting the screening efficiency. If the sand contains impurities (such as soil, organic matter), odor or pollution may be generated during the drying process. The drying sand vibrating screen is suitable for a certain range of particle sizes and characteristics, and may not be suitable for particularly fine or large particles.

3. Operational complexity: The equipment needs to control the screening and drying parameters at the same time, which is difficult to operate and has high technical requirements for operators. If the automatic control system of the drying sand vibrating screen fails, it may affect the entire production process.

4. High energy consumption: The vibration motor of the drying sand vibrating screen needs to consume a lot of electrical energy to maintain high-frequency vibration in order to achieve the screening of the drying sand. Especially for the drying sand vibrating screen with a large processing capacity, its power is relatively large, and long-term operation will incur higher electricity costs.
