Vibratory Screening Machine

Product description

Rotary vibration screen is commonly used screening equipment, the structure includes screen box, vibration motor, vibration damping device and base. When working, the vibration force of the vibration motor makes the screen box high-frequency three-dimensional rotational vibration to achieve accurate screening of materials. It has outstanding advantages, high screening accuracy, and can be carefully graded. Large capacity, suitable for large-scale production; Suitable for a wide range of materials, can screen powder, granular materials; And the running noise is low. However, it also has disadvantages, the screen is prone to friction and wear due to vibration, the effect of dealing with large viscosity and high humidity materials is poor, and the capacity of single machine under the large production scale may not be enough. In general, the rotary vibrating screen has significant advantages and plays a significant role in the material screening link.

Working principle
Vibration motor as a power source, the eccentric block on its shaft produces centrifugal force when rotating, the centrifugal force makes the screen box produce high frequency vibration. This vibration presents the characteristics of three-dimensional rotational vibration, that is, it acts simultaneously in horizontal, vertical and inclined directions. After the material enters the screen surface from the feed port, it is quickly dispersed and makes complex movement under the action of three-dimensional rotary vibration force. Under the combined action of vibration and gravity, the fine-grained material less than the screen size is discharged from the corresponding discharge port through the screen. The coarse particles larger than the screen aperture move in a circle along the screen surface and are finally discharged from the other end of the discharge port to achieve efficient classification and screening of materials.
 
Features & Benefits

High screening efficiency: the unique three-dimensional rotational vibration movement makes the material evenly dispersed on the screen surface and quickly move, avoiding the accumulation and blockage of the material, which can effectively improve the screening efficiency and allow more materials that meet the requirements to pass through the screen in a short time.

Accurate accuracy: By adjusting the Angle and amplitude of the eccentric block of the vibration motor and other parameters, you can precisely control the movement trajectory and residence time of the material on the screen surface, so as to achieve high-precision screening, and can accurately grade the material of different particle sizes.

Strong applicability: According to different material characteristics and screening requirements, replace different materials, mesh screens, but also by adjusting vibration parameters to adapt to a variety of powder, granular and even have a certain viscosity of the material, in chemical, food, medicine, building materials and other industries have a wide range of applications.

Good sealing: the overall structure adopts sealing design, which can effectively prevent the leakage of materials in the screening process, avoid dust flying, not only ensure the cleanliness of the working environment, but also reduce the waste of materials, especially suitable for occasions with high environmental requirements.

Easy maintenance: The structure is relatively simple, the main components are easy to disassemble and install, the screen is convenient to replace, and the key components such as the vibration motor have a long service life, and the daily maintenance workload is small, reducing the maintenance cost and downtime of the equipment.
