In addition, during normal operation, if the slurry concentration is high and the material contains certain impurities (such as sawdust), the filter screen at the outlet of the LM vertical roller mill will also be blocked, resulting in slurry rejection at the outlet of the LM vertical roller mill.

Therefore, we should select a reasonable filter screen aperture and keep the outlet filter screen clean.The LM vertical roller mill is easy to throw steel balls at the outlet.

When the LM vertical roller mill is in normal operation, there will be steel balls thrown out at the outlet, mixed with small stones.

When the inner liner of the ore milling plant is damaged or falls off, obvious impact sound can be heard locally.In case of such situation, stop the ore milling plant as soon as possible and deal with the damaged liner immediately, so as to avoid large-scale damage to the liner of the ore milling plant.

Slurry is easy to be thrown out at the outlet of the ore milling plant.During normal operation of the ore milling plant, slurry flows out of the outlet sundry pipe and is mixed with small stones.

The water material ratio in the ore milling plant is out of regulation, and the amount of water flowing through the cylinder of the ore milling plant is an important parameter in operation, and its size reflects the carrying capacity of solid particles in the ore milling plant.

The high wind pressure causes the fan to heat, which makes the fan temperature too high. During the operation of barite ore grinding plant, unconscious touch may cause the wind pressure of the fan to change, resulting in motor heating. When the fan temperature is too high, it will seriously affect the normal operation of barite ore grinding plant. Therefore, avoid such situations when using barite ore grinding plant.

Due to the equipment itself, for example, the equipment quality is not qualified, which requires users to carefully select large brand and high-quality equipment, such as Zenith barite ore grinding plant. In fact, normal maintenance is also very important, so Zenith suggests that you carry out regular maintenance on barite ore grinding plant to prolong the service life of the equipment.

Zenith specializes in producing Raymond Mill powder machine for more than 20 years, continuously introduces advanced technology at home and abroad, improves and develops barite ore grinding plant, and strives to provide customers with reasonable barite ore grinding plant equipment.

Pay attention to ventilation. The external air can be removed at the dust removal position to make the external air flow convection with the air flow in the cabin, so as to slowly reduce the temperature in the mill room. If necessary, a high-power exhaust fan can be installed for indoor cooling. 

The high wind pressure causes the fan to heat, which makes the fan temperature too high. During the operation of Raymond mill, unconscious touch may cause the wind pressure of the fan to change, resulting in motor heating. When the fan temperature is too high, it will seriously affect the normal operation of Raymond mill. Therefore, avoid such situations when using Raymond mill. 

Due to the equipment itself, for example, the equipment quality is not qualified, which requires users to carefully select large brand and high-quality equipment, such as Zenith Raymond mill. In fact, normal maintenance is also very important, so Zenith suggests that you carry out regular maintenance on Raymond mill to prolong the service life of the equipment. 

When it is found that the vibration sense of the vertical roller mill is strong, the fault cause can be analyzed from the vibration frequency. The vibration feeling is not obvious, which is mostly caused by the dislocation or damage of the indenter.

It is necessary to check the pressurizing device and replace the indenter in time to reset it; When it is found that the vibration sense of the vertical roller mill is strong, it is mostly caused by poor infrastructure, large steel blocks or large hard materials in the vertical roller mill, damage to transmission gears and bearings, etc.

After the problem is diagnosed, appropriate treatment measures can be taken. When it is found that the foundation of the vertical roller mill sinks locally, it is mainly caused by the uneven foundation construction, so it is necessary to stop the machine for treatment and add cushions to make it reach the level; When the vibration of the vertical roller mill often intensifies suddenly, the current changes little with impact sound, and the current increases.

It is very necessary to diagnose the operation state of vertical roller mill equipment, the causes of deterioration and the changes of operation information.

The diagnosis is mainly to compare various symptoms and standards of the vertical roller mill in operation to judge whether the vertical roller mill is in normal operation, so as to find out the causes and eliminate the problems in time before the failure, or predict the operation state of the vertical roller mill according to some symptoms and find the corresponding relationship between performance change and structure change, To make scientific judgments and decisions in order to prevent accidents.

Vertical roller mill diagnosis results and treatment methods for the fault diagnosis of vertical roller mill equipment, many faults will have omens before they occur, such as vertical roller mill sound change, vertical roller mill amplitude change, vertical roller mill temperature change, etc.

First, when purchasing vertical roller mill, you must choose vertical roller mill manufacturers with qualified quality.

Second: when installing vertical roller mill gear, it must be carried out in strict accordance with the requirements of national regulations to ensure that the top clearance, runout and contact of large and small gears meet the specified requirements.

Third: during the subsequent operation of the gear, the working state of the gear shall be checked regularly.

In this regard, SBM will configure corresponding vertical roller mill gears according to the needs and requirements of users, and adopt international well-known brands for supporting manufacturing, which can not only effectively ensure the efficient and stable operation of vertical roller mill, but also greatly reduce various problems of vertical roller mill.
