1. The bucket elevator should be driven with no load. Drain all materials in the hopper before stopping each time, and then stop.
2. it cannot be reversed. Derailment of the chain may occur when it is reversed, and it is very troublesome to troubleshoot the derailment.
3. Feed evenly. It is forbidden to increase the feeding amount suddenly. The feeding amount cannot exceed the conveying capacity of the elevator. Otherwise, it is easy to cause a "stuffy car" accident when the material at the bottom accumulates seriously.
4. Replenish lubricating oil in a timely and appropriate amount.
5. When the chain and hopper are severely worn or damaged, they should be replaced in time.

1. If this problem occurs when the newly purchased product is used for the first time, you should check whether the screen mesh of the rotary vibrating screen is at the same level as the outlet. If the screen mesh and the outlet are not level, it will cause the rotary vibrating screen to discharge The problem of slowness arises.

2. The second case is the adjustment of the motor angle. The angle of the eccentric block of the vibration motor of the rotary vibrating screen can be adjusted to change the trajectory of the material moving on the screen surface. The smaller the angle, the faster the material will spread out ;The larger the angle, the slower the material will spread out. Generally, the motor angle is adjusted to 35 degrees to 45 degrees. If the angle is above 45 degrees, there will be a problem of slow discharge, which is suitable for screening materials with less impurities.

The solution to the slow discharge of vibrating sieve

1. Increase the weight of the two heavy hammers

2. Change the included angle of the upper and lower weights

The installation requirements for screw conveyors are:
1. 20 days before the installation of the screw machine, the foundation should be well watered. This foundation should ensure sufficient stability of the screw machine during operation.
2. Before installing the screw machine, all parts should be thoroughly counted and various pollutants inside and outside should be cleaned.

3. The adjacent flange surfaces should be connected smoothly and tightly, and the misalignment deviation at the joints on the inner surface of the casing should not exceed 1.4mm.

4. Asbestos rubber plates are allowed to be placed between the casing flanges to adjust the accumulated error in the length of the casing and spiral body.

5. The nominal distance between the outer diameter of the screw and the casing is consistent

6. The suspension bearings of the screw conveyor should be reliably fixed on the lifting ears of the casing, and after connecting with adjacent screws, the screw rotation should be uniform. During installation, adjusting shims can be added between the suspension bearing support and the casing lifting ears to ensure that the coaxiality of the spiral axis meets the requirements

7. When the screw machine is single drive, the tail bearing blind cover should be opened, and the distance from the bearing end face to the blind cover should be measured to be less than 20mm.

8. The coaxiality between the main shaft of the screw machine and the reducer shaft should comply with the provisions of GB1184-80 "Regulations on Shape and Position Tolerances without Individual Tolerance Indications".
9. After the chassis of the screw machine is installed, tighten the foundation bolts.
10. Tighten all connecting bolts to a reliable level.
11. The cover of the screw conveyor should be installed in sequence, with a cover buckle installed at an interval of about 0.5m. The last cover at each overlap of the cover should have a cover buckle installed, and one to two cover buckles should be installed at both ends of the screw conveyor to ensure the sealing of the screw conveyor.
12. The dust collection port, feed port, and discharge port should avoid the overlap between the casing flange and the machine cover, and generally adopt on-site welding

The conveying distance of a screw conveyor can be determined based on a variety of factors, including the design and specifications of the screw conveyor, the nature of the material being conveyed, the conveying angle, and the support structure used. Generally speaking, the conveying distance of screw conveyors can range from a few meters to hundreds of meters.

For short conveying distances (within tens of meters), the screw conveyor can usually be installed directly on a support structure, and the motor drives the screw to rotate to transport the material along the pitch direction of the screw.

For longer conveying distances (hundreds of meters), more complex designs and configurations may be required. A common practice is to segment the screw conveyor into sections, usually 10 to 20 meters in length, and then connect the sections through bearings and couplings. This reduces stress and vibration on the entire system and makes maintenance and installation easier.

In addition, in order to support longer distance transportation, additional support structures may be needed, such as pipes, support frames, etc. The design and installation of these structures also need to be considered on a case-by-case basis to ensure the stability and safety of transportation.

It should be noted that the conveying distance of the screw conveyor is too long, which may affect the conveying capacity and efficiency. For longer conveying distances, the fluidity and accumulation of materials also need to be considered to avoid clogging and accumulation.

Therefore, the specific maximum conveying distance of the screw conveyor needs to be evaluated and determined based on the requirements of the actual application and engineering design.

1. Motor: See if the line is broken and crimped, whether the wire is not long enough, whether the motor current is correct, whether the lubricant is injected too much in a single operation.
2. Abnormal sound appears: see if the ring screws are tightened, whether the ring is fully fitted, whether the machine is stable, whether the spring is broken or cracked, the body collides with other hard objects, whether the motor alloy steel screws are loose, Whether the discharge port is in contact with other foreign objects.
3. Raw materials and discharge: observe whether the motor runs in the wrong direction, the angle between the upper and lower eccentric blocks is too large, and the device of the upper and lower eccentric blocks is wrong.
4. Fine mesh is easy to break: whether the raw material directly impacts the mesh surface, whether the fine mesh is tightened, whether the coarse mesh has been damaged, or the rubber pad has been worn thin.
5. The outlet of the stainless steel frame is cracked: whether the overweight pipe is connected or the heavy object is hung, whether the ring is locked evenly.
