Product Description
The variable-frequency multi-stage screen is a specialized screening equipment designed for the wet and sticky mineral raw materials with a fine particle size of 3-6mm. It is widely used in the coal washing and processing industry for the de-powdering of wet and sticky raw coal, in the circulating fluidized bed power generation industry for the screening, crushing, and particle size control of wet and sticky raw coal, and in the metal mining industry for the closed-circuit circulation of high-pressure roller mills and ultra-fine mineral powder screening. It is an essential key screening equipment in the basic industrial sector.
Wet and sticky fine-grained mineral raw materials have strong cohesiveness, poor fluidity, and are difficult to disperse, posing significant screening challenges. The variable-frequency multi-stage screen emphasizes variable-frequency vibration, enabling wet and sticky fine materials to move quickly on the screen with small jump heights, progressing through the screen holes with higher penetration probability, thereby achieving higher screening efficiency and ultra-large processing capacity.
Product Features
1. The screen casing does not vibrate, while the screen mesh vibrates.
2. The screen consists of multiple vibration units, with small-power motors providing independent vibration, resulting in low overall load.
3. The screen angle is adjustable, offering greater processing capacity compared to other models.
4. The screen is equipped with a frequency converter, allowing frequency adjustment between 25-50 Hz.
5. The screen is equipped with a distributor to evenly distribute material across the full width of the screen, ensuring a thin material layer, high screen surface utilization, and reduced screen wear.
6. The screen mesh can be flexibly configured with polyurethane or metal anti-blocking meshes depending on the mineral
friction coefficient.
7. The screen mesh adopts continuous tensioning technology and is designed with a quick-release mechanism.
8. The screen can be designed with multiple layers to achieve grading of various particle sizes.
9. The screen can be arranged in parallel to meet high-capacity requirements.
10. Multiple screens can be combined to achieve ultra-large-scale screening and closed-circuit crushing cycles.
11. The screen is equipped with an automatic lubrication system and a vibration exciter temperature measurement system, allowing remote control.
12.The screening machine is equipped with an automatic oiling system and a temperature measurement system for the exciter, and it can be remotely controlled.
