Requirements of linear vibrating screen for grid structure

In addition to the requirements for the screen mesh, the linear vibrating screen may also have some choices for the grid frame There are two types of grid frame: wooden grid frame and steel grid frame Each type of grid frame has its own advantages: the wooden grid frame is easier to replace the screen mesh, but it is easy to damage; the steel grid frame is not easy to damage, but it is more difficult to replace the screen mesh Here we won't explain in detail In the following chapters, we will talk about the replacement of screen and some matters needing attention 1 After the straight-line screen frame is assembled to the screen box as required, remember to extend the multi cut 50-70mm screen into the corresponding outlet to avoid mixing; 2 When cutting, the straight-line screen width should be consistent with the screen frame, and the screen length must be 50-70mm longer than the straight-line screen frame 3 When the screen is installed, it must be tightened, because the tightness of the screen is an important factor affecting the screening efficiency of the linear screen; 4 When installing the spring ball for cleaning the screen, it must pay attention to the screening difficulty and mesh number of materials, and it cannot be installed blindly 5 When installing the pressing plate of the linear screen, pay attention to its flatness If possible, it is recommended to use the sponge sealing belt with strong expansion to lock it evenly, because this is not only the key to prevent the mixing stage, but also an important factor affecting the service life of the screen 6 If the proportion of materials is large or the number of mesh required for installation of linear screen is high, a suitable supporting mesh shall be added under the screen, so as to play a supporting role, reduce the pressure of materials on the screen and extend its service life 7 After the installation, a few materials shall be used to test the distribution and screening of the screen surface If the materials are evenly transported forward, and the grading is accurate, and there is no mixing phenomenon, then they can be put into use; otherwise, if there is uneven phenomenon such as deviation or clustering, the flatness and evenness of the screen surface of the linear screen or the eccentric hammer angle of the vibration motor shall be adjusted; if there is mixing, the levelness and evenness of the screen surface of the linear screen shall be adjusted Class phenomenon, should check the linear screen screen seal and whether the compression.
