The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad. It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydro power, transportation, chemical industry, smelting and so on.
Vibrating Screen Structure
The body of Vibrating Screen machine is consists of base frame. and supporting structure. The base frame. is welded using heavy channels and angles and special care has been taken during design. Screen supporting structure and Screen are made from wear resistant special Coil Steels.
Vibrating Screen Working Principle
Circular vibrating screen is single-axis circular-movement inertial vibrating screen, the working of circular vibrating screen depends on inertial motor and inertial strength produced by eccentric plate, because of the vibration of screen box, the materials are threw out, so that materials of certain size go through the screen mesh, and the screening aim is realized. Since the magnetic exciter is installed on the gravity center of screen box, the two long elliptical axis form. a shape like a Chinese character, and the upper of long elliptical axis in inlet end is in the same direction with the outlet, which favors the spread of materials which is in the screen box. However, the upper of long elliptical axis in outlet end is opposite to the direction of the outlet, which can reduce the movement speed of materials, and help the difficult-screened materials go through the screen mesh. What’s more, the effective area of screen is increased because of the elliptical screen surface; as a result, the processing capacity is promoted.
Vibrating Screen Operation and Maintenance
1. Before starting, we should inspect every fasteners bolt of vibrating screen whether to become less crowded, if it has, we should fasten it one time.
2. After the sieve machine has empty motion for 4-6 hours, the sieve body should be steady. No sway and unusual sound and driver bearing temperature≤7512.
3. After idle operation movement, we should examine every spots spiral of vibrating screen fastens one time.
4. In normal work, it should have periodic inspection of every fasteners bolt tight situation.
5. Inspect vulnerable, the use and the maintenance frequently, please refer to the instruction for use. (vibrating motor should be refueled one time after 3 months, driver be refueled one time every month, a minor repair half year, a overhaul one year.)
