Vibrating screen takes dual vibration motor drive, when the two vibrating motors do synchronous reverse rotation, the exciting force generated by the eccentric block each other in a direction parallel to the motor axis of the offset, stacked in the direction perpendicular to the motor shaft a force and therefore the sifter’s trajectory is a straight line. Vibratory screen is a kind of doing a vibrating, numerous layers and high efficiency vibrating screen. Round vibrating screen takes a cylinder type eccentric shaft vibration exciter and partial block to adjust the amplitude, material sieve drip line, drum dryer, which has the advantage of reliable structure, strong exciting force, high screen efficiency, low noise, durable usage, easy maintenance and security for the mining operator and which also can be used in the classifying of the products such as mining, building material, transportation, energy saving and chemical industry. The main features of the vibrating screen are as follows: 1. the strong vibration of the screen box will solve the material blocking problems so that we can realize the high screening efficiency and productivity. 2. The simple structure makes it easy for users to change the screen surface. 3. It consumes little power to finish screening materials.With the increasing demands of construction aggregate. The vibrating screen’s net is made up of the upper screening layer and the lower bearing layer. The two layers contact each other quite closely in normal condition. If the net is tensioned to an inappropriate degree, the screen net will vibrate with large amplitude because the upper screening layer is loose while the lower bearing layer is too tight. In this case, it’s also easy for the net to be broken. If the receiving tray cracks, the costs of after-sales will be increased. The attachment of the bouncing ball depends on the screening requirements. Linear vibrating screen new screening equipment with elliptical vibration track is.circular...
