Vibrating screen has been widely used in mining, construction, transportation , energy and chemical industries. Extend bearing life,proper lubrication, protection plans, and bearing condition monitoring should be considered . Inappropriate shaker bearing gap caused by metallic sound . Sharp squeaky noise may be due to inadequate lubrication cause.Dent bearings around the track will cause vibration , resulting in a smooth and crisp sound , scars caused due to the impact , if installed , will produce noise. The preparation screening of vibrating screen . As the name suggests , it refers to the next filter operation processing sequence . In sand production line , for example , the material out of the sand jaw crusher for screening screening machine, stone and sand making production line feed specification , which is crushing mechanism shall be returned to the sand does not meet the jaw crusher .Screening is the method of particle swarm optimization according to particle size,specific gravity, electrostatic and magnetic powder properties of separation. Many kinds of screening equipment, in the mineral processing industry commonly used according to the characteristics of their structure and motion, can be divided into fixed screen, cylindrical sieve, plane shaker, vibrating screen, sieve and sieve probability,these devices have different advantages and scope of application. Mining vibrating screen is a vibration motor for excitation, rubber spring, high wear-resistant material plate, sealing type screen box and other domestic and foreign advanced technology and advanced self synchronous vibration principle, has the characteristics of long service life, low noise, high efficiency screening, a vibrating screening equipment is suitable for sintering ore,and other natural the powdery material. The series vibrating screen adopt a new style of eccentric block which can produce great force make the screen frame vibrating so screening the material on the screen machinery,it is...
