The vibrating screen is major divided into linear vibrating screen, circular vibrating screen (circular vibrating screen), the trajectory of circular vibrating screen is cylindrical, round vibrating screen moves round, it is a efficient new vibrating screen with a number of layers, Circular vibrating screen adopts a cylinder-type eccentric shaft vibration exciter and partial block to adjust the amplitude, material sieve drip line is long and hasmany screening specifications, which is specially designed for quarry screening material stone, also available for mining, coal preparation, mineral , building materials, electricity and chemical industries, and for the use of product classification, it is characterized by reliable structure, strong exciting force, high screening efficiency, low noise, durable, easy maintenance, and the safe use. Round vibrating screen is a kind of high efficiency vibrating screen. It is suitable for quarry screening aggregate, and it is used in the field of coal preparation, mineral processing, building materials, electricity and chemical industries, and product grading. Hongxing vibrating screen is mainly used for the aggregates production line, the aggregates production line production process is roughly as follows: (Silo) - vibrating feeder -> jaw crusher -> impact crusher (Crusher) -> vibrating screen ->sand Washing Machine (finished stone or finished sand), the middle of each device connected through the chute or belt conveyor. Structure of the vibrating screen (vibrating screen): It is made of the vibration source, sieve, sieve screen, damping device, the base, it is characterized by reasonable structure, sturdy and durable. Vibrating screen working principle: using the normal motor to drag the vibrator sieve body, and make the sieve move along the exciting force direction, materials move on the screen surface, so as to achieve the purpose of screening. Structural characteristics of the vibrating screen: 1. Ring groove rivet connection, advanced structure, strong and durable. 2. Adopt tire couplings, flexible connection, and smooth operation. 3. Adopt sieve beams and screen box with high-strength bolts, simple structure, and convenient maintenance. 4. Advanced structure, using block eccentric as excitation force, strong exciting force, low power consumption, small noise. 5. Small amplitude, high frequency, big dip structure, so that the high efficiency of the aircraft screening and largest processing capacity.
