The tightness of at the margin of the sieve is excellent to prevent material leakage. (b) If the wire diameter of the screen is thick, using the stretched wire circle will affect the operation and increase the difficulty screening. Therefore, it had better not use the stretched wire circle. When the vibrating screen is working, under the effect of vibrator, the screen box and screen cloth will move on a circular, oval, or linear motion, which will make the material on the surface of screen scatter and move up and down. Thus, the fine particles can fall through the material layer and then expel from the sieve hole. And the bigger particles will continue to move forward under the effect of vibration. Through the careful observation to the operation process of vibrating screen, the researchers conclude the general steps for the daily maintenance of vibrating screen – Learn the operation state of the equipment through observing and listening.
That is to say, through observing the indicator on the sign, and combining the current amplitude of the equipment operation, give a synthetic judgment for the working state of the vibrating screen. And the listening means listening to the operation voice of the working equipment to know whether the situation of equipment components loosing exist. Discover in time and dispose in time. General Motors Company is often mentioned in discussions such as these. Another thing to notice is that the internal dust of the vibrating screen should be cleaned regularly. The domestic vibrating screens can be divided into circular vibrating screen, linear vibrating screen, vibrating oval screen, high frequency vibrating screen, high frequency vibrating fine screen, sieve bend, banana vibrating screen, probability screen, cold griddle, hot griddle and dewatering screen, which are more than 50 series and nearly 1000 kinds of specifications. The products have been widely used in many industries, such as metallurgy, mining, coal, electricity and building materials, which basically meet the needs of domestic economic construction. According to the industry survey in 2002, the screening machinery manufacturing enterprises have been more than 300.
