Resonance screening example
At present, there are only a few manufacturers of resonance screens in China, such as Anshan Mine, Zhongzhong and Shangye Mine, and there are few types and specifications, all of which produce elastic link type resonance sieves (Table 1). The installation methods are all seat type. . Saddle ore production 3 sizes of GL type resonance screen, for coal, metallurgy, electric power, building materials, light industry and other industrial sectors for the grading of fine materials, dehydration, mud and sculping screening. Medium-heavy production of a GL-type double-layer resonant sieve with the largest domestic size and a screening area of ​​30m 2 is suitable for classification, dehydration and de-intermediation of coal, rock, ore and other materials with a particle size of less than 300mm. Shangye Mine is an early manufacturer of resonant screens in China, but the model is older and is almost no longer produced.
Table 1
Generally, the resonance sieve is divided into a single layer and a double layer, and the screen structure has two types of a punching sieve plate and a slit sieve plate. The mesh size is provided as required, the motor can be installed on the left side or the right side, and the foundation bolt is all used by the user. Bring your own. These are the design or user needs to note or pay attention to when selecting or ordering.
The dimensions and installation dimensions of the 2GL1540 Resonant Screen, GLM2075 and 2GLM2075 Resonance Screen are shown in Figures 1 and 2, respectively.
2GLM4075 Resonance Screen: The upper and lower screen boxes move in opposite directions, the whole device has good dynamic balance, and the dynamic load transmitted to the foundation is small. Since the buffer with gap is installed, the nonlinear characteristic of the system vibration is formed, the vibration characteristic curve is close to the resonance interval, and the slope is reduced, so that the amplitude variation of the resonance screen is small, and the work balance is good. The dimensions of the resonant screen are shown in Figure 3.
