Short life of slurry screening equipment has long plagued the mineral processing industry. The main reasons are harsh operating conditions: continuous slurry corrosion, high-frequency mechanical vibration, enormous processing loads, and highly abrasive solid particles.
High Frequency Vibrating Screen significantly improves the service life and reliability of the equipment through a series of technological innovations.
Coreal Machinery has compiled some information for your reference.
The core technology mechanism of the High-Frequency Vibrating Screen to solve the pain point of short life
1. High-Frequency, Low-Amplitude Vibration Principle: The High-Frequency Vibrating Screen utilizes a high-frequency, low-amplitude operating mode. Low amplitude significantly reduces impact stress between the screen mesh and the screen body, reducing metal fatigue and structural damage. The high frequency allows fine slurry particles to vibrate gently and quickly through the screen, shortening screen retention time and reducing wear.
2. Advanced Excitation System and Power Transmission: Modern High-Frequency Vibrating Screens are often equipped with an externally sealed eccentric vibrator and an elastic coupling to drive the screen mesh. The power source is separated from the screen box, which is subject to slurry abrasion and impact, optimizing the motor's operating environment and extending its lifespan. The flexible connection absorbs impact, compensates for installation errors, and protects the motor bearings and transmission system.
3. Core Wear-Resistant Material Application:
Polyurethane (PU) Screen: Its wear resistance is 3-8 times that of steel screen, extending replacement cycles. It exhibits elasticity and toughness, allowing secondary vibration to prevent clogging under high-frequency vibrations. It is resistant to water and chemicals, preventing corrosion, and also reduces noise and equipment load.
Wear-Resistant Liner: Wear-resistant metal or ceramic liners are installed at the slurry inlet and screen box areas prone to wear to protect the main structure from erosion.
4. Reasonable Structural Design and Mechanical Optimization:
Main Body Reinforcement: Ribbed side panels and a box-beam structure are employed. Optimized through finite element analysis, this reduces weight while maintaining strength, eliminating stress concentration and preventing cracking.
Vibration Isolation Optimization: Rubber springs are used instead of steel springs for vibration isolation, better absorbing high-frequency vibration energy, reducing dynamic loads on the foundation, and extending fatigue life.
Modular Screen: The modular design of the screen allows replacement of only the damaged module, eliminating the need for a complete replacement, saving maintenance time and spare parts costs.
