The effective and perfect automatic control of LM series vertical roller mill can make the system adjust to…

Large scale ultra vertical mill is a new industrial project to recycle construction waste. With the continuous development of domestic sand and stone industry, the demand for ultra vertical mill is increasing.

In order to control the generation of dust in the process of crushing and sand forming, it is necessary to update the technology, The ultimate vertical mill is designed according to…

How can we choose a reliable manufacturer when choosing ultrafine vertical mill? This time, I will provide some suggestions for you to choose ultra vertical mill.

1. When choosing materials, we will choose high hardness and wear-resistant high manganese steel. The high manganese steel looks thick and smooth. When crushing materials, it has high strength and long wear time. When choosing…

Along with the rising demands of product fineness, fine-powder grinding technology is widely applied. The conveying facility of such equipment is ultrafine vertical mill. However, the capacity of ultrafine vertical mill sometimes can be much lower than designed. According to operating experiences, we summerize some reasons and solutions.

1.Insufficient bucket loading Loading quantity…

1. the joint surface of hydraulic components may be damaged during assembly and maintenance of vertical roller mill , or the paper pad is damaged by pressure oil, or there is flatness error in the joint surface during the repair or the screw of the joint is not tightened, etc. all may cause the joint surface leakage; If the operation is barbaric and excessive force, especially the knock on the cylinder block…

At atmospheric pressure, about 10% of the air can be dissolved in the hydraulic oil, and more air or gas will be dissolved in the oil under the high pressure of the hydraulic system. Air bubbles form in the oil. If the hydraulic system of vertical roller mill changes rapidly between high and low pressure in a very short time during the working process, the bubbles will burst at high temperature on the…

When the fault occurs, you need to touch the oil inlet pipe and radiator by hand, and find out whether there is temperature difference, so as to check the operation of the radiator.

The step is to check the quantity of working oil and the brand of oil used.

There are many reasons for the high oil temperature of vertical roller mill. Although these reasons are reflected in the vertical mill, it…

Vertical mill is an important mechanical equipment commonly used in highway engineering construction. Under the working condition of vertical mill, the phenomenon of ultra-high hydraulic oil temperature of vertical roller mill.

Although the machine is designed to work when the oil temperature can reach 120 ℃, in fact, when the oil temperature reaches 100 ℃, the machine will fail to work and the seal will…

This step is also a very important link to effectively prevent the belt from deviation. In a vertical roller mill equipment, there are several rollers, and the installation position of each roller and the center position of the movement direction of the length of the vertical roller mill should be in a vertical state. If it is not in a vertical state and the deflection is very large, then there will be…

The installation sequence of vertical roller mill should be the first to install the head frame, then the middle frame of each section, and finally the tail frame. Before installing the frame, the center position of the conveyor should be determined first, and all the working operation centers of the conveyor should be in a straight line.

In the process of installing each frame, the longitudinal…

The output of vertical roller mill often throws out ungrinded crushed stones, and the amount is relatively large, which not only increases the power consumption of grinding materials, but also increases the labor intensity of personnel. So what is the reason for this phenomenon?

The particle size of imported material is too large, resulting in insufficient output of vertical roller mill and stone…

The scraping range of hollow shaft bearing shells of vertical roller mills in smelters should be controlled at contact angle less than 35 according to the actual production requirements Below, it also needs to scratch clearance on both sides.

The spot distribution of contact should be distributed evenly and evenly along the whole length of bus, and there should be no excessive imbalance. The distance…

Bearing bush is the key part of vertical roller mill. The problem often occurs is that the temperature is overheated, which leads to the performance disorder. Generally speaking, its complexity mainly involves the following conditions:

In view of the typical faults encountered in the production of vertical roller mill, this paper analyzes the causes in detail and gives the targeted technical…

The electric roller is divided into internal electric roller and external electric roller. The main difference is that the built-in electric roller motor is installed inside the roller, and the external electric roller motor is installed outside the roller and rigidly connected with the roller.

The built-in electric roller motor has poor heat dissipation, and is generally used in the ultrafine…

The quality of seal structure design is related to the effect of seal and the life of seal ring. The sealing effect of the O-ring depends on the correct size of the mounting groove. The installation groove of the sealing ring is too deep, the compression of the sealing ring is not enough, so the sealing structure should be designed and processed reasonably to ensure the good sealing performance of the sealing device.

Install the sealing ring correctly to ensure the good sealing of the…

Prevent the equipment temperature from rising too high. If the working temperature of vertical roller mill is high, it is easy to cause plastic deformation of the liner under the impact and grinding of the material. Therefore, the lubrication of the equipment should be done well to reduce the phenomenon of too high temperature rise of the equipment and the plastic deformation of the lining plate.

The…
