Working Principle of Vibrating Screen. Vibrating Screen (or Gyratory Screen) works on the principle of gyratory motion. The sieve placed on the rubber mounting rotates in a circular manner on a fixed axis by means of an eccentric flywheel.
Functional principle of a vibrating screen. The Allgaier vibrating screens are driven by a powerful vibration motor that generates an individually adjustable horizontal and circular tumbling motion. This causes the bulk material to move in a spiral pattern from the inside to the outside, resulting in efficient screening.
The dewatering screen is also called "dewatering vibrating screen", a common mining dewatering equipment.Also called sand and gravel dewatering screen, mining dewatering screen, coal slime dewatering screen, tailings dewatering screen, etc. The main function of the machine is dehydration, desliming, and demediation to solve the problem of water …
"A vibrating motor imparts both linear and vertical motion to a deck or screen surface, causing particles to move across the screen. As these particles encounter the openings in the screen mesh, smaller particles pass through, while larger ones are retained." The applications of vibrating screens are diverse, spanning various industries.
