Vibration motor is equipped with a set of adjustable eccentric blocks at both ends of the rotor shaft,utilizing the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block,thus the exciting force is obtained.It offer exciting vibration source for all kinds of vibrating machines such as vibrating screen, vibrating feeder, vibrating conveyor, vibrating flask shaker, vibrating crusher, vibrating molding machine, vibrating sand mixer, vibrating buffing machine, vibrating test-bed, etc.in power plant, building materials, grain, coal, mine, metallurgy, chemical industry, light industry, casting, railway, port and other industries. IP Grade IP (INGRESS PROTECTION) grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION ).IP grade is composed of two numbers, the first number represents for anti-invasion grade of external objects and dust, the second number shows the sealing degree of anti- invasion of moisture and water, if the number is greater, the degree of protection will be higher
