Vibratory Screening Machine

Product description

The rotary vibrating screen is a highly efficient screening equipment. It uses a vertical vibrating motor as the power source and generates three-dimensional compound vibrations in horizontal, vertical and inclined directions through upper and lower eccentric weights, causing the materials to move in a spiral parabolic motion on the screen surface. It adopts a multi-layer screen structure, which can complete the classification of multiple particle sizes at one time, and the screening efficiency is 30% higher than that of traditional equipment. The modular quick-disassembly design facilitates the rapid replacement of the screen mesh. The rubber spring shock absorption and low-noise operation reduce the environmental impact. The components in contact with materials are made of stainless steel, which is suitable for clean scenarios such as food and medicine. It can also be equipped with a screen cleaning device to prevent material blockage. It is widely used in fine screening operations in multiple industries such as chemical engineering, food, and new energy.

Working principle
The rotary vibrating screen takes the vertical vibrating motor as the power core. Through the eccentric weights at the upper and lower ends, it generates three-dimensional compound vibrations in the horizontal, vertical and inclined directions, causing the material to move in a spiral parabolic motion on the screen surface. After the material enters from the top, it diffuses in all directions under the action of vibration. Fine particles smaller than the aperture of the screen fall through the screen, while coarse particles are discharged along the edge of the screen. Multi-stage screening is achieved through multiple layers of screens. At the same time, the vibration amplitude and trajectory can be changed by adjusting the counterweight of the weight hammer and the phase Angle to adapt to the characteristics of different materials. Combined with the bouncing ball or ultrasonic cleaning device, it can prevent the screen from being clogged. It is widely used in fine screening operations in the chemical, food, pharmaceutical and other industries.
 
Features & Benefits

The rotary vibrating screen, with its unique design and functions, has demonstrated significant advantages in the field of material screening. Its three-dimensional compound vibration enables the materials to fully contact the screen, and the screening efficiency is increased by more than 30% compared with traditional equipment. Multi-layer screens can complete multi-stage screening with a single feeding, reducing the floor space and energy consumption of the equipment. The parameters are flexible and adjustable. By changing the counterweight and Angle of the weight hammer, it can adapt to different materials ranging from coarse particles to fine powder. The modular quick-disassembly structure enables the screen to be replaced in just 10 minutes, making maintenance convenient. The low-consumption shock-absorbing design ensures that the noise is ≤75dB and the operation is stable. The stainless steel material and sealing design comply with hygiene standards and are suitable for the food and pharmaceutical industries. The net cleaning device can also effectively solve the problem of material blockage.
