Linear Vibratory Sifter

Introduction of Linear Vibratory Sifter

Linear vibratory sifter is suitable for dry powder or granular materials, as well as products with a high proportion of super large particles. 2-7 different levels can be achieved in one operation.

Linear vibratory sifter is divided into three different materials: carbon steel, stainless steel, and plastic. With the help of the weights installed on the upper and lower ends of the motor shaft, the exciting force of the motor is transmitted to the screen surface, and the screens of several specifications are produced through the multi-layer screen. The upper material and the lower material are discharged from their respective discharge ports. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust overflow, automatic discharge, and is more suitable for assembly line operations.

Working Principle of Linear Vibratory Sifter

Working Principle

Driven by dual vibratory sifter, when two vibrating motors rotate synchronously and in opposite directions, the excitation force generated by the eccentric blocks cancels each other out in the direction parallel to the motor axis, and stacks in the direction perpendicular to the motor axis to form a resultant force. Therefore, the trajectory of the screen is a straight line. There is an inclination angle between the two motor shafts relative to the screen surface. Under the reasonable action of the exciting force and the material's self-gravity, the material entering the equipment is thrown up on the screen surface, jumping forward and making a linear parabolic movement, which is produced by the multi-layer screen. Several specifications of the oversize and undersize items are discharged from their respective discharge ports to achieve the purpose of screening and classification.

Benefits of Linear Vibratory Sifter


1. The screening range is from 20-400 mesh, and the output can reach 20 tons per hour.

2. Equipped with double motors, which are installed vertically to each other to obtain proper vibration flow. The arrangement of the double motors makes the screen frame move and vibrate in a straight line perpendicular to the motor, so that the super large particles have a good forward effect.

3. Materials can be screened into 2, 3, 4, 5, 6 or 7 different grades, because it can build 1-6 layers.

4. Equipped with an adjustable vibration motor, which can help achieve different speeds and vibration levels according to the degree setting.

5. The fully enclosed structure can ensure that there is no dust pollution during the screening process.
