Overview
The MFS coal powder screen is specially designed to meet the strict requirements of screening coal powder in high-temperature industrial environments.
It adopts advanced vibration technology to ensure stable operation under harsh conditions, ensuring both screening efficiency and equipment durability.
The screen box is equipped with heat-resistant structures and sealing components, providing long service life and reliable performance.
This series is widely used in metallurgy, power plants, mining, building materials, and coal preparation plants, receiving consistent praise from end users.
Working Principle
The screen is driven by a vibration motor. Through the combined action of a primary vibrator, a secondary vibration plate, and dual vibration motors, the screen box performs reverse synchronous operation.
This generates powerful excitation forces, enabling periodic elastic motion of the screen surface.
Material fed into the screen is subjected to high-frequency vibration and directional movement, allowing fine particles to pass through rapidly while coarse particles are discharged smoothly.
This ensures stable material stratification and efficient screening.
Structural Features
- Integrated steel plate design — strong rigidity, reliable structure, and extended service life.
- Dual-vibration motor drive — high excitation force with stable synchronous motion.
- Multi-layer dynamic structure — primary vibration plate, secondary vibration plate, and bottom plate work together to enhance screening strength.
- High adaptability — suitable for hot materials, viscous materials, wet coal, and materials with strict environmental conditions.
- Excellent sealing performance — prevents dust leakage and ensures clean operation.
- Low noise and reduced dynamic load — thanks to optimized vibration structure and compact layout.
- Flexible installation — the motor can be positioned on either side of the screen to suit layout requirements.
- Low maintenance — fewer wearing parts and convenient disassembly.
