When the valve of oil inlet pipe is not opened to the right position, it shall be adjusted to the right position in time; When the oil return groove on the bearing pedestal or spherical bearing bush is blocked, stop the machine for inspection and clean the oil return groove and oil return pipe in time.
Regularly check the wear of lining plate and the tightness of fasteners, and timely tighten...
The quality of lubricating oil becomes worse
reason:
During the operation of ultrafine vertical mill, when the seal of the water seal dust-proof device is not tight, a large amount of dust will enter into the lubricating oil in the machine body, so that the oil quality of the lubricating oil will be rapidly deteriorated, resulting in poor lubrication, causing accidents such as large and small...
In order to reduce the energy consumption of air flow and improve the production efficiency ultrafine vertical mill, we must first understand the reasons.
Generally speaking, the forms of solid particles accelerated by high-speed airflow are mainly composed of the following three methods:
Airflow particle acceleration nozzle: the airflow and particles are fully mixed and then accelerated...
The general development trend of non-metallic mineral raw materials or materials in the future is high purity, superfine and functionalization. Taking the high-purity and ultra-fine non-metallic mineral deep processing raw materials as the leader, comprehensively develop and utilize various non-metallic minerals. Although high-purity ultrafine powders can be prepared by chemical synthesis, the...
The ultrafine vertical mill is simple and compact in structure and high in reliability, and it is an important grinding equipment in metallurgy, chemical industry, cement, ceramics, construction, power and other fields.
However, the shortcomings of ultrafine vertical mills are obvious, that is, high energy consumption and high iron loss. In recent years, with the increase of energy...
At present, the biggest problem faced by the cement industry is serious overcapacity. To solve this problem, in addition to eliminating part of the production capacity through the survival of the fittest in the market, it is more important for enterprises to speed up the optimization and upgrading, promote the development of cement products in the direction of high technology, low energy...
Technology is also very important for mining machinery and equipment. The process mainly refers to the structure and shape of the equipment itself, and whether the steel plate welding is smooth, clean, seamless and other details.
As we all know, the general high-quality equipment has fine workmanship, and every detail is handled very well. The whole welding area is flat and clean, and there is...
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.

In order to prevent and control the leakage of the cement mill gydraulic system, strengthening the management and standardizing maintenance and repair procedures of hydraulic oil is an important way to control the hydraulic oil pollution and finally prevent the leakage of the cement mill gydraulic system. Therefore, the following three aspects of management must be strengthened in the...
Before starting the vertical roller mill, the operator needs to do some inspection work to ensure that all parts are normal and there is no material blocking in the crushing chamber. In addition, the inspection before startup can also help you find the fault in time, prevent the trouble in advance, and avoid greater losses. So, what aspects need to be checked before starting the vertical...
