In mining screening equipment, the vibrating screen plays a vital role in mining production. The vibrating screen is a device that uses the exciting force generated by a vibrating motor or an exciter to make the material toss, jump, and move forward on the screen surface, thereby realizing the process of screening, grading, dehydration, etc.
Working principle of vibrating screen
The working principle of the vibrating screen mainly relies on the self-synchronous rotation of the vibrating motor or the exciter to make the screen box produce linear vibration or circular vibration. After the material falls into the screen box from the feed end, it quickly moves forward, loosens, and penetrates the screen under the action of the vibration force to complete the screening operation. When the hot ore screen is working, the screen plate is in direct contact with the high-temperature material, and it is required to have good wear resistance and heat resistance. Therefore, heat-resistant alloy cast steel and other materials will be used, and a thermal compensation mechanism will be provided to ensure that the screen plate is firmly fixed.
Types of vibrating screens
There are various types of vibrating screens. According to different vibration trajectories, they can be divided into linear vibrating screens, circular vibrating screens, banana screens, arc screens, elliptical screens, etc. Each type has its own unique advantages and scope of application, for example:
1. Linear vibrating screen: suitable for de-mediation and dehydration of materials, with simple structure and high screening efficiency.
2. Circular vibrating screen: suitable for pre-screening or grading screening of materials, with large processing capacity and high screening accuracy.
In the mining industry, vibrating screens are mainly used to screen materials such as ore, coal, limestone, etc. to ensure the quality and purity of the materials.
• Ore screening: The raw ore is screened through a vibrating screen to separate ores of different particle sizes to meet the needs of subsequent processing or sales.
• Coal screening: In coal production, vibrating screens are used to grade coal according to particle size to improve the utilization value of coal.
• Dehydration and desludging: In the wet beneficiation process, vibrating screens can also be used for dehydration and desludging of materials to improve the dryness and cleanliness of the product.
