Product Description

Flashover screen is a kind of equipment used for screening fine, sticky, wet (such as viscous high moisture raw coal and coke of medium and fine particle size classification) and other difficult to screen materials, its design principle is by a single drive to produce double vibration, that is, through resonance, by a driver to provide two vibrations: linear vibration driven by the exciter fixed frame and vibration generated by the floating screen frame. The two move relative to each other. Especially in the case that the material being processed is prone to clogging the screen, the relaxation screen can achieve very high screening efficiency with a relatively small screen area and ensure that the screen is not clogging. Widely used in coal, electric power, coal chemical industry, metallurgy, building materials and other industries.

Product Performance

Working Principle

The relaxation vibrating screen is developed from the traditional circular vibrating screen, using the double vibration principle of basic vibration and additional vibration, the basic vibration is the circular vibration generated by the rotation of the eccentric block, and the additional vibration is the oval vibration driven by the basic vibration. The two reference masses vibrate relative to each other at the same frequency. Because the two ends of the surface are respectively installed on the fixed frame and the floating frame, the polyurethane screen surface continuously expands and contracts, thereby obtaining higher acceleration. The relative linear motion of the two reference masses is adjustable, and all necessary parameters can be adjusted according to the different components. The linear vibrating fixed screen frame and the excited floating screen frame form a resonance system, and the two produce relative motion.
