The reason and solution of the slow feed of vibrating feeder

Vibrating feeder is a commonly used feeding equipment. In the production, it can send block or granular materials uniformly and continuously to the receiving equipment, which is the front-line process of the entire production line. After that, it often breaks with the jaw crusher. The working efficiency of the vibrating feeder not only has an important impact on the production capacity of the jaw crusher, but also on the production efficiency of the entire production line.

Some users have reported that the vibration feeder has a problem of slow feeding, which affects production. This article shares 4 reasons and solutions for the slow feed of the vibrating feeder.

Reasons for slow feed of vibrating feeder

Solution: Adjust the installation angle. Choose the fixed position of both ends of the feeder according to the site conditions.

Solution: Adjust by checking whether the two vibration motors are consistent.

Solution: The wiring of any one of the vibration motors needs to be adjusted to ensure that the two motors run in reverse, and the vibration path of the vibration feeder is straight.

Solution: It can be adjusted by adjusting the position of the eccentric block (the adjustment of the excitation force is achieved by adjusting the phase of the eccentric block. One of the two eccentric blocks is fixed and the other is movable. Loosen the bolts of the movable eccentric block. When the phases of the eccentric blocks coincide, the excitation force is very large, which decreases in turn; when adjusting, the phases of the eccentric blocks of the same group of motors should be consistent).

  • 1. The inclination of the chute is not enough
  • 2. The angle between the eccentric blocks at both ends of the vibration motor is inconsistent
  • 3. The vibration direction of the vibration motor is consistent
  • 4. The vibration motor has insufficient excitation force

In order to ensure the feeding speed and stable operation of the vibrating feeder, the following precautions are required for installation and operation:

Installation and use of vibrating feeder

The vibrating feeder is used for batching and quantitative feeding in order to ensure uniform and stable feeding and prevent the material from flowing freely. It should be installed horizontally. For continuous feeding of general materials, it can be installed down by 10 °. For viscous materials and materials with large water content, it can be installed by tilting down 15 °.

After installation, the vibrating feeder should be left with a clearance of 20mm, the horizontal should be horizontal, and the suspension device should be flexible.

Before the no-load test run of the vibrating feeder, all bolts should be tightened once, especially the anchor bolts of the vibrating motor, which should be re-tightened once after continuous operation for 3-5 hours.

The vibration feeder should always check the amplitude, the current of the vibration motor and the surface temperature of the motor during the operation, and it is required that the amplitude is uniform before and after, without swinging left and right, and the current of the vibration motor is stable. If an abnormal situation is found, it should be stopped immediately.

The lubrication of the vibration motor bearings is the key to the normal operation of the entire vibration feeder. During the use process, the bearings should be filled with grease regularly, once every two months, once a month in the high temperature season, and dismantled every six months Once the motor, replace the internal bearing.

1. Before starting

  • (1) Check and exclude the presence of materials between the body and the chute, springs and brackets that affect the movement of the body;
  • (2) Check whether all fasteners are fully tightened;
  • (3) Check whether the lubricating oil in the exciter is higher than the oil standard height;
  • (4) Check whether the drive belt is good, and replace it in time if it is damaged, and clean it if it is oily;
  • (5) Check whether the protective device is good, and remove it in time if there is any unsafe phenomenon.

2. When using

  • (1) Check whether the condition of the machine and transmission part is normal before starting;
  • (2) It must be started without load;
  • (3) After starting, if any abnormal situation is found, it should be stopped immediately, and it can be restarted only after the abnormality is identified and eliminated.
  • (4) Only after the machine has stabilized and vibrated, it can run with material;
  • (5) The feeding should meet the load test requirements;
  • (6) Shutdown should be carried out in accordance with the technological sequence. It is forbidden to shut down with materials or continue feeding during or after shutdown.
