Feed mixer is an indispensable equipment in modern breeding industry. It ensures that the nutritional needs of animals are met by efficiently and evenly mixing various feed raw materials. However, in the actual operation process, feed mixer sometimes has noise problems, which not only affects the working environment of operators, but also may indicate equipment failure or wear. This article will discuss in detail the reasons for the noise of feed mixer during operation and the corresponding solutions.

1. Causes of noise in feed mixer

Loose parts: During the long-term use of feed mixer, due to vibration and friction, some screws, nuts and other fasteners may gradually loosen, resulting in collision and friction between parts, thus making noise.

The gap between the mixing blade and the barrel wall is too large, which may also cause the material to hit the barrel wall during mixing, causing noise.

Bearing wear: Bearing is an important part of the feed mixer, and its lubrication state directly affects the running stability and noise level of the equipment. When the bearing is not lubricated enough or the lubricating oil is not replaced for a long time, the bearing wear will increase, resulting in noise.

Bearing damage is also an important source of noise. If the ball or raceway inside the bearing is worn, peeled off, etc., it will cause the bearing to run unsteadily and produce abnormal noise.

Transmission system failure: The transmission system of the feed mixer includes components such as motors, pulleys, and reducers. When any of these components fails, noise may be generated. For example, loose or worn pulleys can cause the belt to slip or break, resulting in sharp noise.

Wear or poor meshing of the gears inside the reducer can also cause noise. In addition, faults in the motor itself (such as winding short circuit, rotor imbalance, etc.) may also cause noise.

Material blockage: At the feed inlet or outlet of the feed mixer, if the material is too much or too wet, it may cause material blockage. At this time, the equipment needs to overcome greater resistance to push the material, which will cause noise.

Impurities in the material (such as metal fragments, stones, etc.) may also get stuck in the mixing mechanism, causing the equipment to run poorly and generate noise.

Improper installation: The installation position and method of the feed mixer have a great impact on its operating stability. If the equipment is installed on an uneven or unstable foundation, or if it is not calibrated and fixed according to the requirements of the instructions during installation, it may cause vibration and noise during the operation of the equipment.

In addition, if the supporting structure of the equipment is not strong enough or there is resonance, it will also amplify the impact of noise.

2. Solutions to the noise of feed mixers

Check and tighten parts: Check the fasteners of the feed mixer regularly to see if they are loose, especially the key parts such as the mixing blades and bearing seats. Tighten the loose parts in time to reduce the noise caused by collision.

Adjust the gap between the mixing blade and the barrel wall to the appropriate range (generally recommended to be 5-10mm) to reduce the noise of the material hitting the barrel wall.

Replace or repair bearings: Check the lubrication and wear of the bearings regularly. If the bearing is found to be insufficiently lubricated or severely worn, lubricant should be added or replaced with a new bearing in time.

Replace damaged bearings immediately to avoid damage to other parts and increased noise caused by bearing failure.

Maintain the transmission system: Check the working status of transmission parts such as pulleys and reducers regularly. Replace the pulleys with severe wear in time; adjust or repair the gears in the reducer if they are not meshed well.

Ensure that the motor runs smoothly and without abnormal noise. If a motor failure is found, repair or replace the motor in time.

Clear material blockage: Check the feed and discharge ports of the feed mixer regularly to see if they are unobstructed. The blocked materials should be cleaned up in time to avoid noise caused by overload operation of the equipment.

Before the materials enter the mixer, they should be screened to remove impurities and large pieces of materials to reduce the risk of noise caused by impurities blocking the mixing mechanism.

Optimize the installation method: Ensure that the feed mixer is installed on a flat and solid foundation to avoid increased equipment vibration and noise caused by unstable foundation. For large equipment, you can consider using shock-absorbing pads to further reduce vibration and noise levels.

Correctly install and calibrate the equipment according to the instructions to ensure that the relative positions of the various components are accurate to reduce noise problems caused by improper installation.

Use noise reduction materials and technologies: Adding noise reduction materials such as sound insulation cotton or sound insulation boards to the outer shell of the feed mixer can effectively absorb and isolate the spread of noise and reduce the noise level of the equipment during operation.

The use of advanced noise reduction technologies such as active noise reduction systems or mufflers can also further improve the noise reduction effect of the equipment, but it should be noted that the cost of these technologies is relatively high and needs to be selected and applied according to actual needs and economic conditions.

Strengthen daily maintenance and care: formulate detailed daily maintenance and care plans and strictly implement them to ensure that all parts of the feed mixer are always in good working condition, thereby reducing noise problems caused by equipment failure or wear.

Train operators to master the correct operating methods and maintenance knowledge to improve their professionalism and sense of responsibility to reduce the frequency of equipment failure and noise problems caused by human factors.

In short, the noise of the feed mixer during operation is a common problem, but as long as we master the correct solution, we can effectively reduce the noise level, improve the operating efficiency and service life of the equipment, improve the comfort of the working environment, and protect the health of the staff.
