Compared with ordinary linings, the heat resistance and strength of composite linings have been greatly improved. Especially in service life, the composite lining is twice the function of traditional lining, which greatly improves the economic benefits of enterprises.

In addition, the composite lining has low noise, low weight and is easy to be popularized, but lacks practice. However, it has broad market prospects and has great development space in dealing with aging and wearing of lining.

In conclusion, in order to deal with such problems as the wear of lining plate of vertical roller mill, it is necessary to analyze the reasons for the wear of lining plate and put forward corresponding measures.For example, reasonable selection of steel balls and lining plates, control of the running state of the vertical roller mill, use of new material lining plates, etc., thus reducing unnecessary losses in operation.Welcome to leave a message to communicate your problems.

Material and heat treatment process of liner directly determine the mechanical properties of liner and will have an important impact on the wear of liner.If the lining material is not properly selected and the heat treatment process is unreasonable, the fatigue strength and service life of the lining will be greatly reduced, which will not meet the requirements of grinding operation of vertical roller mill, and even cause some problems such as plastic deformation and drum.

Heat treatment of lining plate is an important way to reduce wear of lining plate of vertical roller mill. Therefore, proper heat treatment process should be selected according to the material of lining plate.However, in actual work, the relevant staff lacks the knowledge of lining material, so in heat treatment, the processing of lining is not enough, which not only does not play a strengthening role, but also makes the strength of lining lower. When hit by steel balls and materials, plastic deformation will occur.

Grinding machine is widely used in grinding of mineral products in metallurgy, building materials, chemical industry, mines and other fields. According to the fineness of the plastic and the fineness of the material, the grinding machine can be divided into many kinds, such as Raymond grinding, superfine grinding, trapezoidal grinding, etc.

The production efficiency of vertical roller mill directly affects the profit of the manufacturer. For the factors affecting the production efficiency of the ultrafine vertical mill, more attention must be paid to it in the production. Today, we will discuss with you what factors affect the efficiency of the ultrafine vertical mill.

Material hardness is an important factor affecting the production efficiency of vertical roller mill. The harder the material, the more difficult it is to process, and the more serious the wear of the equipment.

When the user demands the higher the particle size of the finished product, the smaller the grinding ability of the grinder. Because the material needs to be ground in the grinder for a longer time, the finished products produced in the same time are relatively small and the production efficiency is reduced. If you have high requirements for the material discharging granularity, you can add other equipment according to your own production capacity and economic strength to ensure the production efficiency.

Besides the external factors described above, there are also some internal factors that will also affect the production efficiency of the grinder, such as improper operation of the operator and insufficient lubrication of the equipment. In the actual production, we should avoid these problems in time according to the actual situation, so as to improve the production efficiency of ultrafine vertical mill and ensure the economic benefits of the enterprise.

The wear of the nozzle ring and damage to the upper cover of the nozzle ring cause the wind speed in vertical roller mill to not reach the design wind speed, and the material cannot be lifted in time, causing spitting.

The grinding disc ring is severely worn, the gap is enlarged, and the air leakage is serious, causing slag spitting.

The guide cone is severely worn and cannot effectively play the role of guiding logistics and airflow.

The grinding roller skin and the grinding disc liner are severely worn, which causes the grinding pressure to drop, the grinding effect is not good, and the internal circulation load of vertical roller mill increases and causes slag spitting.

According to the actual situation, disengage the automatic grinding group when necessary, manually control the amount of coal, stabilize the load and steam temperature and vapor pressure. Immediately contact the coal handling duty officer to check the coal level of the original coal hopper to determine whether the original coal hopper is empty;

When the coal vertical roller mill is not tripped and the raw coal enters the coal vertical roller mill intermittently, the coal vertical roller mill must be cut to manual adjustment in time, strictly control the outlet temperature not to exceed 80 ℃, and put in fire-fighting steam when necessary to avoid air dust caused by the broken coal The ratio imbalance causes dust explosion in the coal vertical roller mill;

Strengthen the combustion adjustment, put oil in time for unstable combustion, start the backup coal vertical roller mill in time according to the load, and pay attention to the change of the main steam pressure and main steam temperature of the boiler.

The barrel is an important part of the vertical roller mill, and the price is relatively expensive. After the liner is installed in the barrel, the barrel will not directly bear the impact and grinding of the grinding medium and the material to be ground, thereby protecting the barrel and extending the barrel and the entire The service life of the equipment. The lining board and the cylinder body are tightly combined, and also play a role in enhancing the rigidity of the cylinder body.

In other words, the automatic grading liner can gather the larger steel balls in the same grinding bin at the feed end of the bin to smash larger pieces of material, and at the same time make the smaller steel balls gather at the discharge end of the bin.

With the advancement of technology, new material liners have also begun to be used in vertical roller mill. For example, a composite liner composed of rubber and cemented carbide steel can ideally solve the contradiction between the toughness and rigidity of the liner and reduce the liner. The impact force received during operation. 

Compared with ordinary liners, the heat resistance and strength of composite liners have been greatly improved. Especially in terms of service life, composite liners are twice as effective as traditional liners, which greatly improves the economic benefits of enterprises. In addition, the composite liner has low working noise, light weight, and is easy to promote, but it lacks practice. However, there is a lot of room for development in dealing with the problems of liner aging and liner wear.

Pay attention to the heating and cooling operation of the vertical roller mill. Most manufacturers do not pay attention to the heating and cooling operations of vertical roller mills, and fail to realize that reasonable heating and cooling operations can prolong the service life of key large bearings and wear parts.

Reasonable heating rate can heat the roller sleeve, liner plate and bearing uniformly, thereby prolonging the service life of the liner plate, roller sleeve and key bearing. Among the spare parts of the vertical roller mill, the price of these key parts is relatively expensive, and any one of them is damaged. Will directly affect the operation cycle of the vertical roller mill.

When welding construction in the vertical roller mill, attention must be paid to the connection and grounding of the welded parts. Welding current must not pass through the bearing or twisted point, otherwise it will damage the bearing or twisted point.
