In contrast, the MVS high-frequency electromagnetic vibrating screen uses an electromagnetic exciter to drive the screen mesh to vibrate independently, while the screen box remains stationary. Its vibration frequency reaches 50Hz with an amplitude of 1-2 millimeters, and the vibration intensity is 2-3 times that of traditional vibrating screens. It can effectively break the surface tension of materials, greatly improve the probability of fine-grained materials passing through the screen, with a screening efficiency of more than 70% and better classification accuracy.
There are significant differences between the two in terms of energy consumption and operation and maintenance. Traditional vibrating screens mostly use motors to drive inertial exciters, resulting in high overall power consumption. In addition, the vibration of the screen box generates large dynamic loads, requiring special foundation support. After long-term operation, component wear is prone to occur, screen hole clogging is frequent, and the maintenance frequency and cost are high. The MVS high-frequency electromagnetic vibrating screen has a single exciter power of only 0.15KW, with extremely low overall power consumption, making it an energy-saving equipment. It adopts rubber elastic components, with small dynamic load and no need for special foundation. Moreover, the screen surface is composed of three layers of flexible screen mesh, which can automatically clean the screen holes with the intermittent instantaneous strong vibration function, greatly reducing clogging, extending the service life of the screen mesh, and reducing maintenance costs and workload.
In terms of operational adaptability, the adjustment of vibration parameters of traditional vibrating screens is cumbersome, mostly fixed parameters, which are difficult to flexibly adjust according to material properties. In addition, their structure is fixed, with limited applicable scenarios, mostly suitable for the screening of coarse-grained materials. The MVS high-frequency electromagnetic vibrating screen is controlled by computer integration, which can flexibly compile vibration parameters and support on-site or remote control, with simple operation. The installation angle of the screen machine can be adjusted according to material properties, and it adopts a modular design, with various structures such as single-double channel and single-multi layer, which can be flexibly customized. It is suitable for various operation needs such as dry and wet screening and dehydration of fine-grained materials in many industries such as mineral processing, coal preparation and building materials, with stronger adaptability.
