ADPLUS Vibrating Screen. Trimax ADPLUS Vibrating Screen offers industry-leading screening efficiency with heavy-duty tough construction. The unique "Butterfly" design of the centrifugal counter weights not only allows flexibility in terms of amplitude, more importantly, it reduces unnecessary stress on the side walls of the vibrating screen.
What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.
In this wire mesh screening deck, the vibratory shaft is coupled to the centre of the alloy-toughened mesh sorting sieve. As it operates, short-wavelength jerks are delivered by a centrally mounted solenoid. Principle 2: Flywheel Weighted. Instead of a jerking motion, the screens move in larger wavelength loops.
