Stone sand vibrating screen is to separate a mixture of different-sized stones and raw materials into multiple, uniform product grades based on particle size. Before selecting a specific model, we must first understand the primary types of vibrating screen.
Circular vibrating screen:
The vibrator generates a circular motion, causing material to travel in a spiral path across the screen deck. This action provides a combination of stratification and conveyance.
This vibrating screen is better for screening medium to coarse materials (e.g., crushed stone, ores, coal). They are ideal for high-capacity sizing and scalping operations where high throughput is a priority.
Linear vibrating screen:
The vibration is straight-line, propelling material down the deck at a consistent rate. This creates a uniform, straight-path travel.
This vibrating screen is for fine to medium-sized materials, dewatering, and desliming. Their controlled, linear motion is excellent for precise separations where particle travel speed needs to be managed.
High-Frequency vibrating screen:
As the name implies, these screens operate at a much higher speed (RPM) with a low amplitude. This creates a sharp, rapid vibration that minimizes blinding (pegging) of near-size particles.
This vibrating screen is used for fine and wet materials, especially where screen blinding is a major concern. They are the go-to solution for efficient fines recovery.
Selection of vibrating screen
When selecting the suitable vibrating screen, a comprehensive selection process must account for:
Material Characteristics: What is the particle size, shape, moisture content, and abrasiveness?
Capacity Requirements: What is the required tons-per-hour throughput?
Screening Efficiency: How critical is the precision of the final product gradation?
Operational Environment: Will the screen be installed in a dry or wet process? Indoors or outdoors?
Total Cost of Ownership: This includes not just the initial purchase price, but also energy consumption, maintenance downtime, and spare part costs.
Why Choose the Luoyang Dahua YK Series Vibrating Screen?
The frequency, amplitude, and angle of the vibrating screen can be adjusted to ensure a higher screening efficiency.
It can be equipped with tensioned modular wire mesh and polyurethane mesh, which have different sieve size.
The exciter adopts a block eccentric external modular integrated design, which can be automatically lubricated by grease or thin oil.
The side panel is flaged and connected to the beam and support seat with high-strength bolts, ensuring that the entire screen is free from welding fatigue stress.
Anti-vibration technology is employed to prevent lateral shaking caused by resonance during start-up and shutdown.
The vibrating spring is made of a rubber spring, which ensures stable vibration and low noise.
An optional for dust seal device of the vibration screen.
