The insulation resistance should be measured when the roller screen is used after being placed for a long time

   Roller screen Hybrid solutions:

First, check the sealing degree of drum screen frame and screen body. A sealing strip is arranged between the screen frame and the screen body of the drum screen for sealing. The commonly used materials for sealing strips are natural rubber and silica gel. After the roller screen is used for a period of time, the sealing strip will be deformed or broken. It is suggested that the user should check the usage of the sealing strip regularly when using the roller screen, and replace it in time if it is damaged.

The second is the cause of the screen rupture. The screen of drum screen is a vulnerable part, and different screen materials have different wearing methods. In the continuous operation of the screen, the load of the screen is very large, which will damage the screen. In the production process should be found and replaced in time. Ensure the quality of screening materials.

Then the small particles on the sieve surface can not run completely on the sorting surface. Usually this is mainly the angle of the vibration motor. In general, the motor angle is adjusted to 65 degrees at the factory. In use, the motor angle can be adjusted according to the screening conditions of materials. In order to change the running track of materials on the screen surface. Thus, the screening accuracy is improved.

Drum screen electrical protection device:

1. During the initial operation of the machine, check the anchor bolts at least once a day to prevent loosening.

2. The drum screen shall be equipped with electrical protection device.

3. When the rotation direction of the motor does not meet the requirements, just adjust the power phase sequence.

4. The motor should be well lubricated. Replenish lithium base grease (zl-3) every two weeks or so. When refueling, add an appropriate amount of lithium grease through the oil cup. When sealed bearings are used, the motor is not equipped with an oil cup.

5. After the machine runs for 1500 hours, the bearing should be checked. If the bearing is seriously damaged, it should be replaced immediately.

6. Insulation resistance should be measured when it is used for a long time after being placed for a long time. When measuring a 500 V megohmmeter, it should be greater than 0.5 megohm.

Today, the editor teaches you how to install the screen frame in the roller screen. After changing the framework, I hope it can help you:

1: installation of wooden grid

The wood grid is divided into two types: Poplar and pine. Poplar accounted for more than 90% of the total. When installing wooden grid, its two ends should be high. Poplar has good toughness. After you have fixed part of the screen to the end of the grid frame, lower the bottom of the screen frame. The screen is naturally tightened by hand. Note that the flatness of the screen surface is sufficient. It should be noted that particularly thin screens should reduce tension. After installation, the middle part will be released slowly to restore the screen frame to its natural state. At the same time, remove both end pads and gently level both ends. After that, strengthen the nets on both sides. After completion, fix the strips on both sides, which requires the discharge end to extend forward about 2 cm to prevent mixing at the discharge end. After the screen is installed in the screen machine, the screen will become tight.

2: iron frame

The installation of the iron frame is more complicated. This requires that the middle of the frame should be designed to be concave and convex. After naturally tightening the screws on both sides, press the middle part into the bead. If the screen is thin, it is recommended to have a nylon lining at the bottom when installing the mesh cover. Protect the screen. The screw shall be symmetrically tightened on both sides of the material, and then the material end in the middle shall be pressed out.
