Electromagnetic Vibrating Screen(MVSz Screen)
MVS SCREEN(Electromagnetic Vibrating Screen)
The screening system adopts a brand-new design principle and fully-new structure with screen mesh vibrating only. It owns 14 patented techniques, has passed the technical appraisal organized by Hebei Science and Technology Department, and Liaoning science & Technology Department. It is now widely used in industries of metallurgical mineral processing, coal preparation, construction material, chemicals and foodstuff, etc.
1.The screen mesh is vibrated while screen box remains stable. The exciter is fixed on the screen box and drives the transmission system to vibrate the screen mesh. As the vibrating system is designed to work in a nearly resonant state, only a smaller power is needed for reaching the specified operation parameter. Because the whole screen box is unmoved and the whole machine supported by rubber damping sring, the dynamic load is very small. Therefore, no special foundation is required, and the machine can be placed anywhere.
2.The screen mesh is vibrated at a high frequency of 50Hz, with the amplitude being 1～2mm, and the vibration intensity is 8～10 times that of the acceleration gravity, 2～3 times that of the common vibrating screens. The screen mesh has a strong self-cleaning function, a high screening efficiency and a high throughput capacity. As a result, it is very suitable for screening and dewatering of fine powder materials,with a maxium feeding size of 15mm and a classification sizing –range of 0.043～3mm.
3.The screen installation angle can be easily adjusted at any time to meet the different feed properties and screening operations. For wet screening in concentrators, the installation inclination angle is 25±2° and for dry screening operation, 33±2°.
4.The screen's vibrating parameters are central-controlled by computer and the vibrating parameters for each vibrating system can be set and adjusted through software programming. Besides the vibrating parameters for general operation,intermittent-instant-strong-vibration parameters can also be set to keep a non-blinding sieving.
5.The specially designed electromagnetic vibration system is connected by high-quality rubber parts to ensure a reliable long-time operation. It has small power consumption-each electromagnetic vibration exciter only 0.15kW. The installed power for MVSK2420 – a model commonly used in mineral processing, is only 1.2kW. Therefore, this type of machine is energy-conserving.
6. Electric is configured for each screen machine. Different controller models are optional according to customers' requirements so as to realize many attached functions such as digital control, centralized remote, process recording and fault alarm.
