Vibration Screener Machine

Vibration screener machines are widely used in the fertilizer industry due to their high screening efficiency, thorough dust removal, and reliable operation. The equipment utilizes high-frequency vibration, resulting in excellent separation of fine powder and small particles, making it particularly suitable for final dust removal of finished granules. The screen mesh is made of stainless steel or polyurethane, offering wear and corrosion resistance and a long service life. The vibrating motor is specially designed for stable operation under prolonged vibration. The machine has a compact structure, low operating noise, and simple maintenance. For fertilizer companies requiring strict control over finished particle size and appearance, vibration screener machines are highly efficient and durable fine screening equipment.

Working Principle

The screen box vibrates directionally under the excitation force of the vibrating motor. Material is continuously thrown up and fallen on the screen surface, creating a jumping forward motion. During each throw and fall, particles contact the screen surface; fine particles pass through the screen holes and fall to the lower layer, while coarser particles continue forward. Vibration loosens and stratifies the material, allowing small particles to settle to the bottom of the material layer and contact the screen surface, increasing the probability of passage. Multiple screens sequentially separate the material into different particle size grades, achieving multi-stage screening.

Performance Characteristics

Thorough Powder Removal: High-frequency vibration ensures fine powder passes through the screen, achieving a powder removal rate of over 90%.

High Screening Accuracy: Clear material stratification and accurate particle size classification, suitable for fine screening.

Commendable Processing Capacity: Large processing capacity per unit screen surface, meeting the requirements of small to medium-capacity production lines.

Long Screen Life: Stainless steel and polyurethane screens are wear-resistant and corrosion-resistant, with a long lifespan under normal use.

Stable Operation: Dedicated vibrating motor and shock absorption design ensure smooth and reliable operation.

Minimum Maintenance: Simple structure; only the screen and springs are vulnerable parts, making replacement easy.

Maintenance Methods

Check screen tension and damage every shift; repair or replace immediately if damage is found.

Clean residual material from the screen surface and remove dust from the screen box.

Tighten vibrating motor anchor bolts and screen clamping bolts weekly to prevent loosening.

Check shock absorption springs monthly for deformation or breakage; replace any abnormal ones promptly.

Add dedicated grease to the vibrating motor bearings quarterly; check motor wiring and insulation.

Replace all screens and shock absorption springs during annual overhaul; check screen box welds for cracks and repair welding if necessary. The vibration motor should be maintained according to the manufacturer’s specified maintenance schedule.
