How to adjust the upper and lower weight of the rotary vibrating screen?

Rotary vibrating screen is a kind of high-precision fine powder screening machine with low noise and high efficiency It takes 3-5 minutes to change the screen quickly It is totally closed structure and suitable for screening and filtering of particles, powder, mucus and other materials Rotary vibrating screen is a new type of high-precision fine-grained screening equipment, which can achieve satisfactory screening effect for particles and fine powder Under the excitation of the vibrator, the screen body produces the compound rotation vibration, which forces the material to form the track vortex in the screen machine This kind of vortex is very useful for the screening of the material By adjusting the relative position of the upper and lower hammers of the rotary vibrating screen, we can improve the movement track of the material on the screen surface, extend or shorten the residence time of the material on the screen surface, so as to achieve the ideal screening effect The following is a brief introduction to the adjustment method of the upper and lower hammers of a lower rotating vibrating screen, as follows: 1 Adjustment of additional weights An additional weight block is installed in the first measurement of the upper and lower weights Its function is to increase and decrease the exciting force of the screen machine according to the number of layers of the user's screen machine and the specific gravity of the materials The increase and decrease of the additional weight block can make the screen machine achieve a good screening effect of Zui 2 Do not adjust the angle of the upper hammer of the rotary vibration screen, open the adjustment hole of the bottom barrel, loosen the fixing bolt of the lower hammer, and adjust the phase angle of the upper and lower hammers in the opposite direction of the discharge port according to the screened material track (refer to the figure below) Then put a small amount of materials on the screen to make the screen machine run, and check the movement track of the screen surface materials If the processing parameters are all good, stop the machine and tighten the fixing bolts, and the adjustment is over (remember to tighten the fixing bolts) Note: sometimes due to the influence of the specific gravity, humidity, stacking angle and other parameters of the material, it is impossible to adjust the phase angle once, so the user should have enough patience to adjust, so that the screen machine can play its due rate 3 By changing the phase angle of the upper and lower hammers, the movement track and residence time of the material on the screen can be changed In order to adapt the screening machine to the separation state required by various materials, such as material distribution, handling capacity, separation efficiency, mesh passing rate and other changes, it should be adjusted to the Zui good state
