The noise of the máquina de mistura de argamassa seca mainly comes from the bearings, especially the transportador de parafuso.

O elevador de parafuso é um equipamento rotativo de alta velocidade, and the length is generally more than 3 meters in a planta de argamassa de mistura seca. If the screw shaft is not concentric during manufacturing, the screw blade will likely rub against its wall, resulting in noise.

Além disso, the bearings below the hoist are generally buried in the ground. After a long time, it is easy to cause the lower path to lack lubricating oil, e ao mesmo tempo, powder enters the bearing, which causes the direction to die violently and generate noise.

How should we solve it?

For these noises, we not only need to strictly control the production process to prevent the conveyor shaft from being misaligned but also do an excellent job of sealing the bearing position, and we need you to do a good job in the maintenance of the equipment during use, and every 3 meses. The bearings below the hoist are filled with lubricating oil. If the output is too large and the working time of the mixer is too long, the maintenance time should be shortened. Ao mesmo tempo, all bearing positions should be filled with lubricating oil to avoid generating noise.

Primeiro, we need to know that there are two primary noise sources in the dry mortar mixing machine: the screw conveyor and the reducer. In the cycloid reducer used in the dry mortar mixer machine, the reducer drive’s friction, vibration, and collision will generate noise.

The noise of the reducer is a kind of high-frequency noise, and its frequency is generally up to 20,000 times per second. It isn’t easy to eliminate by ordinary means. The noise caused by the reducer mainly comes from the friction between the gear and the shaft, so it is best to improve the contact surface of the equipment and stick to reduce the friction between them.

How to effectively reduce or prevent the noise of the reducer?

Em primeiro lugar, the reducer should be filled with oil before use. The reducer is not filled with lubricating oil before leaving the factory. Geralmente, industrial gear oil or diesel oil can be added. The oil filling should not exceed the upper limit of the oil standard. Please pay attention to the amount of fat; it is best to change the oil every six months.

To sum up, the best way to reduce noise is regular maintenance, lubrificação, and replacement of worn parts. The noise of the dry mortar mixing machine is annoying. We need to take some measures to put forward strategies to suppress the noise of the mixing engine so that it won’t affect our work and life. If properly maintained and properly used, it can be operated safely.
