Peneira vibratória

O ecrã vibratório is an efficient and reliable mining classification machine widely used for screening and grading bulk materials such as ore, coal, sand, gravel, slurry, and other mineral materials. By applying continuous and controlled vibratory motion, the equipment separates materials according to particle size, ensuring the appropriate feed size for downstream processes such as mineral processing, crushing, washing, and material handling.

A vibrating screen mainly consists of a screen deck and a vibrator. Different screen mesh sizes can be selected according to the material characteristics and screening requirements. In general, coarse screening can be performed at around 50 mesh, while fine screening can reach approximately 80 mesh.

Key Functions & Applications

• Ore & Mine Processing: Classifies crushed metallic ores (iron, copper, gold) and non-metallic minerals (limestone, phosphate). Removes fines or oversize particles before grinding or beneficiation.
• Coal Preparation: Segregates coal by size for washing, combustion, or transport.
• Aggregate & Construction: Grades sand, gravel, and crushed stone for concrete, asphalt, and road base.
• Slurry & Dewatering: Separates solids from liquids in tailings or dredged materials.

Tipos de crivos vibratórios

• By application: mining vibrating screen, light fine vibrating screen, experimenta/laboratory vibrating screen
• By motion trajectory or structure: linear vibrating screen, circular vibrating screen, high-frequency vibrating screen, double-deck vibrating screen, single-deck vibrating screen, and so on.

Advantages of Vibrating Screen

• High Screening Efficiency – Vibrating motion helps separate materials quickly and efficiently.
• Good Size Separation – It separates materials into different particle sizes accurately.
• High Capacity – It can process large amounts of ore, coal, sand, gravel, and other materials.
• Wide Application – It is suitable for mining, aggregate, coal, sand, and mineral processing.
• Simple and Reliable – The strong structure allows stable operation in tough working conditions.
• Continuous Operation – Materials are continuously fed, screened, and discharged, improving production efficiency.
• Easy to Maintain – The simple design makes inspection, screen replacement, and maintenance easier.
• Flexible Screening – Different screen sizes can be used for different material and particle-size requirements.
• Better Downstream Processing – Properly sized materials help improve the efficiency of crushing, washing, and other processing equipment.

Mining vibrating screens are designed for the harsh operating conditions of mining operations, characterized by high loads and high wear. Compared to conventional screening equipment, they offer key advantages such as high screening efficiency, wear resistance, and stable operation, making them the primary screening equipment in industries such as mining and metallurgy.
