Find out a suitable method to improve the screening efficiency as much as possible under the premise of unchanged processing parameters.
The vibrating motor, as the vibrating source of the vibrating screen has the advantages of reasonable design, simple structure, compact, high excitation efficiency, energy saving and easy installation.
The selection of vibration motor includes operating frequency, maximum exciting force, power and other parameters.
The linear vibrating screen with advantages of dehydration, sculping, desliming and effective screening is used widely for screening products.
During the working process, the main parts of vibrating screen endure long time high-frequency alternating loads, often resulting in crack on lateral board and beams.
The strength problem is much more serious for large-scale linear vibrating screen.
With the increase in coal mining mechanization, the requirements on the vibrating screen machine are increasing, therefore, the research, design, and manufacture on the large-scale linear vibrating screen has become more important.
A 27m2 large-scale linear vibrating screen was developed by the original Tangshan Coal Research Institute as the research object.
In the view of the breakage of beam fracture and the short operation life in domestic vibrating screens, from the perspective of dynamics and kinematics, dynamic performance analysis on the vibrating screen has been done.
Currently, new types of vibration sieve products are being sought to increase processing capacity and screening efficiency.
The system optimization of screening machinery, the unreliability of the vibration mode, the fatigue life, and vibration and noise pollution problems, screening technology and other issues of difficult sieving material are the seeking topics in the developing process of vibrating screen.
