Supporting pressurization grinding roller combination module for vertical roller mill

Abstract

The invention relates to the field of a supporting pressurization grinding roller combination module for a vertical roller mill. The supporting pressurization grinding roller combination module comprises an upright (1), wherein a grinding roller shaft (11) capable of rotating around the upright is connected to the upper end of the upright (1); a grinding roller (9) is arranged at the end part of the grinding roller shaft (11); and a grinding roller pressurizing device is arranged between the middle part of the grinding roller shaft (11) and the lower part of the upright (1). The supporting pressurization grinding roller combination module for the vertical roller mill is designed modularly so that the roller mill is miniaturized.

Description

technical field [0001] The invention relates to the field of a supporting pressure grinding roller assembly module for a vertical roller mill. Background technique [0002] The vertical roller mill integrates the functions of grinding, drying, classification (powder selection) and conveying, and has the advantages of high efficiency, low energy consumption, low abrasion, high operation rate, compact structure, small site and space occupation, low noise, The fineness of the product is easy to adjust and other obvious advantages, and it is more and more widely used in the grinding and ultrafine grinding of cement (raw meal, coal, clinker), metallurgical slag, materials, chemical industry and other materials. [0003] At present, there are three types of domestic vertical mills: 2-roll, 3-roll, and 4-roll. With the large-scale production lines of cement and metallurgical slag, the output is getting higher and higher. In order to meet the needs of production lines, large-scale m...

Problems solved by technology

[0003] At present, there are three types of domestic vertical mills: 2-roll, 3-roll, and 4-roll. With the large-scale production lines of cement and metallurgical slag, the output is getting higher and higher. In order to meet the needs of production lines, large-scale mills have become a development trend. , the current vertical roller mill basically enlarges the diameter of the grinding roller according to the principle of geometric similarity, resulting in an increase in the individual mass of the grinding roller, which also increases the dynamic load, and the vibration and noise of the mill

At the same time, the increase in the diameter and quality of the grinding roller also brings about an increase in the height and weight of the grinding table supporting the mill, thus increasing the cost of manufacturing, transportation and installation
