Vibrating Screen

The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyration vibration, while the lower rotating weight causes the screen surface to produce a conical gyration vibration. 

The combined effect causes the screen surface to produce a complex gyration vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface motion trajectory and change the motion trajectory of the material on the screen surface.

Vibrating screen is a mechanical equipment that uses vibration to screen materials such as ores. It is mainly used to classify materials with different particle sizes according to particle size. The following is a detailed introduction and manufacturing process of vibrating screen: - **Detailed introduction**: - **Working principle**: The vibrating screen generates reciprocating rotary vibration through the excitation of the vibrator, making the materials on the screen surface move up and down and in the forward direction. At the same time, due to the different movement of materials of different particle sizes, layering occurs, thereby strengthening the screening of fine particles. - **Basic structure**: The vibrating screen mainly consists of parts such as an exciter, a working body (screen box), and elastic elements (supporting or hanging devices). The exciter is used to generate exciting force. The working body is the working part that performs periodic movement. Elastic elements include main vibration springs and isolation springs. - **Classification**: There are many types of vibrating screens. According to the type of movement trajectory of their screen boxes, they can be divided into vibrating screens with circular movement trajectories (circular vibrating screens) and vibrating screens with linear movement trajectories (linear vibrating screens). According to whether they are close to or far from the resonance frequency, they can be divided into resonance screens and inertial screens. According to different exciting forces, vibrating screens can be divided into eccentric vibrating screens, inertial vibrating screens and electromagnetic vibrating screens. - **Application fields**: Vibrating screens are widely used in chemical, food, pharmaceutical, metallurgy, building materials and other industries. They are mainly used for filtering impurities and grading particle sizes. - **Manufacturing process**: - **Design and material selection**: According to the use requirements and working conditions of the vibrating screen, design and select materials. Select appropriate materials such as steel and rubber to ensure the strength and durability of the vibrating screen. - **Processing and manufacturing**: According to the design drawings, perform processing and manufacturing. This includes processes such as cutting, welding, and drilling to manufacture various parts of the vibrating screen. - **Assembly and debugging**: Assemble the manufactured parts and install the exciter, screen box, elastic elements, etc. Then perform debugging to adjust parameters such as the amplitude and frequency of the vibrating screen to ensure its normal operation. - **Quality inspection**: Perform quality inspection on the manufactured vibrating screen, including appearance inspection, dimensional inspection, and performance testing. Ensure that the vibrating screen meets relevant standards and requirements. - **Packaging and transportation**: Package the inspected vibrating screen to protect it from damage during transportation. Then transport it and deliver the vibrating screen to the user. It should be noted that different types of vibrating screens may have different manufacturing processes. The specific manufacturing process should be determined according to the type and requirements of the vibrating screen.
