Vibrating screen machine manufacturer: How to improve the screening rate of mine screening equipment

Vibrating screen is one of the commonly used classification equipment in concentrator. What is the importance of vibrating screen equipment? Vibrating screen machine manufacturers to take you to understand. Mining vibrating screen using vibration motor vibration, rubber spring vibration reduction, high wear-resistant material screen plate, sealed screen box and other excellent technology at home and abroad and excellent self-synchronous vibration principle, with long life, low noise, high screening rate characteristics, suitable for sinter, natural ore, coke and other powdery materials of a vibrating screening equipment.

In the production practice, the raw materials of vibrating screen machine equipment are mostly cylindrical (particle feed classification) or irregular particles, and the sieve is both circular and rectangular. The state of the material particles when they contact the sieve has a great influence on whether the particles can pass through, such as a 4×10 mm particle can pass through a 5 mm aperture sieve when it is upright, and the transverse can not. Therefore, the passage of particles has a certain contingency, can only be studied by statistical means. Generally for cylindrical particles, rectangular sieve through performance is better; For the irregular particles with small size difference in each direction, the passing performance of round holes is better.

One of the necessary conditions for screening process is that there is a suitable relative motion between the screening material and the screen surface. The method of producing this relative motion can be the horizontal reciprocating linear motion of the screen surface (rotation), vertical reciprocating linear motion (vibration) or a combination of both. Screen body only horizontal reciprocating motion or vertical reciprocating motion, screening effect is not ideal. The latter due to the lack of material and screen surface horizontal relative motion, easy to cause uneven material thickness. The practice shows that the rotary vibrating screen combined with two kinds of motion has better effect. There is also the material characteristics, such as material moisture absorption, it is necessary to control the temperature of the site, different use of the environment also has an impact on the screening effect.
